Inherits TQScrollView.
Inherited by TQDataTable.
TQTable is easy to use, although it does have a large API because of the comprehensive functionality that it provides. TQTable includes functions for manipulating headers, rows and columns, cells and selections. TQTable also provides in-place editing and drag and drop, as well as a useful set of signals. TQTable efficiently supports very large tables, for example, tables one million by one million cells are perfectly possible. TQTable is economical with memory, using none for unused cells.
TQTable *table = new TQTable( 100, 250, this );
table->setPixmap( 3, 2, pix );
table->setText( 3, 2, "A pixmap" );
The first line constructs the table specifying its size in rows and columns. We then insert a pixmap and some text into the same cell, with the pixmap appearing to the left of the text. TQTable cells can be populated with TQTableItems, TQComboTableItems or by TQCheckTableItems. By default a vertical header appears at the left of the table showing row numbers and a horizontal header appears at the top of the table showing column numbers. (The numbers displayed start at 1, although row and column numbers within TQTable begin at 0.)
If you want to use mouse tracking call setMouseTracking( TRUE ) on the viewport; (see TQScrollView).
TQTable supports a header column, e.g. to display row numbers, and a header row, e.g to display column titles. To set row or column labels use TQHeader::setLabel() on the pointers returned by verticalHeader() and horizontalHeader() respectively. The vertical header is displayed within the table's left margin whose width is set with setLeftMargin(). The horizontal header is displayed within the table's top margin whose height is set with setTopMargin(). The table's grid can be switched off with setShowGrid(). If you want to hide a horizontal header call hide(), and call setTopMargin( 0 ) so that the area the header would have occupied is reduced to zero size.
Header labels are indexed via their section numbers. Note that the default behavior of TQHeader regarding section numbers is overriden for TQTable. See the explanation below in the Rows and Columns section in the discussion of moving columns and rows.
Row and column sizes are set with setRowHeight() and setColumnWidth(). If you want a row high enough to show the tallest item in its entirety, use adjustRow(). Similarly, to make a column wide enough to show the widest item use adjustColumn(). If you want the row height and column width to adjust automatically as the height and width of the table changes use setRowStretchable() and setColumnStretchable().
Rows and columns can be hidden and shown with hideRow(), hideColumn(), showRow() and showColumn(). New rows and columns are inserted using insertRows() and insertColumns(). Additional rows and columns are added at the bottom (rows) or right (columns) if you set setNumRows() or setNumCols() to be larger than numRows() or numCols(). Existing rows and columns are removed with removeRow() and removeColumn(). Multiple rows and columns can be removed with removeRows() and removeColumns().
Rows and columns can be set to be moveable using rowMovingEnabled() and columnMovingEnabled(). The user can drag them to reorder them holding down the Ctrl key and dragging the mouse. For performance reasons, the default behavior of TQHeader section numbers is overridden by TQTable. Currently in TQTable, when a row or column is dragged and reordered, the section number is also changed to its new position. Therefore, there is no difference between the section and the index fields in TQHeader. The TQTable TQHeader classes do not provide a mechanism for indexing independently of the user interface ordering.
The table can be sorted using sortColumn(). Users can sort a column by clicking its header if setSorting() is set to TRUE. Rows can be swapped with swapRows(), columns with swapColumns() and cells with swapCells().
For editable tables (see setReadOnly()) you can set the read-only property of individual rows and columns with setRowReadOnly() and setColumnReadOnly(). (Whether a cell is editable or read-only depends on these settings and the cell's TQTableItem::EditType.)
The row and column which have the focus are returned by currentRow() and currentColumn() respectively.
Although many TQTable functions operate in terms of rows and columns the indexOf() function returns a single integer identifying a particular cell.
All of a TQTable's cells are empty when the table is constructed.
There are two approaches to populating the table's cells. The first and simplest approach is to use TQTableItems or TQTableItem subclasses. The second approach doesn't use TQTableItems at all which is useful for very large sparse tables but requires you to reimplement a number of functions. We'll look at each approach in turn.
To put a string in a cell use setText(). This function will create a new TQTableItem for the cell if one doesn't already exist, and displays the text in it. By default the table item's widget will be a TQLineEdit. A pixmap may be put in a cell with setPixmap(), which also creates a table item if required. A cell may contain both a pixmap and text; the pixmap is displayed to the left of the text. Another approach is to construct a TQTableItem or TQTableItem subclass, set its properties, then insert it into a cell with setItem().
If you want cells which contain comboboxes use the TQComboTableItem class. Similarly if you require cells containing checkboxes use the TQCheckTableItem class. These table items look and behave just like the combobox or checkbox widgets but consume far less memory.
for ( int j = 0; j < numRows; ++j )
table.setItem( j, 1, new TQCheckTableItem( &table, "Check me" ) );
In the example above we create a column of TQCheckTableItems and
insert them into the table using setItem().
TQTable takes ownership of its TQTableItems and will delete them when the table itself is destroyed. You can take ownership of a table item using takeItem() which you use to move a cell's contents from one cell to another, either within the same table, or from one table to another. (See also, swapCells()).
In-place editing of the text in TQTableItems, and the values in TQComboTableItems and TQCheckTableItems works automatically. Cells may be editable or read-only, see TQTableItem::EditType. If you want fine control over editing see beginEdit() and endEdit().
The contents of a cell can be retrieved as a TQTableItem using item(), or as a string with text() or as a pixmap (if there is one) with pixmap(). A cell's bounding rectangle is given by cellGeometry(). Use updateCell() to repaint a cell, for example to clear away a cell's visual representation after it has been deleted with clearCell(). The table can be forced to scroll to show a particular cell with ensureCellVisible(). The isSelected() function indicates if a cell is selected.
It is possible to use your own widget as a cell's widget using setCellWidget(), but subclassing TQTableItem might be a simpler approach. The cell's widget (if there is one) can be removed with clearCellWidget().
For large, sparse, tables using TQTableItems or other widgets is inefficient. The solution is to draw the cell as it should appear and to create and destroy cell editors on demand.
This approach requires that you reimplement various functions. Reimplement paintCell() to display your data, and createEditor() and setCellContentFromEditor() to support in-place editing. It is very important to reimplement resizeData() to have no functionality, to prevent TQTable from attempting to create a huge array. You will also need to reimplement item(), setItem(), takeItem(), clearCell(), and insertWidget(), cellWidget() and clearCellWidget(). In almost every circumstance (for sorting, removing and inserting columns and rows, etc.), you also need to reimplement swapRows(), swapCells() and swapColumns(), including header handling.
If you represent active cells with a dictionary of TQTableItems and TQWidgets, i.e. only store references to cells that are actually used, many of the functions can be implemented with a single line of code. (See the table/bigtable/main.cpp example.)
For more information on cells see the TQTableItem documenation.
TQTable's support single selection, multi-selection (multiple cells) or no selection. The selection mode is set with setSelectionMode(). Use isSelected() to determine if a particular cell is selected, and isRowSelected() and isColumnSelected() to see if a row or column is selected.
TQTable's support many simultaneous selections. You can programmatically select cells with addSelection(). The number of selections is given by numSelections(). The current selection is returned by currentSelection(). You can remove a selection with removeSelection() and remove all selections with clearSelection(). Selections are TQTableSelection objects.
To easily add a new selection use selectCells(), selectRow() or selectColumn().
Alternatively, use addSelection() to add new selections using TQTableSelection objects. The advantage of using TQTableSelection objects is that you can call TQTableSelection::expandTo() to resize the selection and can query and compare them.
The number of selections is given by numSelections(). The current selection is returned by currentSelection(). You can remove a selection with removeSelection() and remove all selections with clearSelection().
When the user clicks a cell the currentChanged() signal is emitted. You can also connect to the lower level clicked(), doubleClicked() and pressed() signals. If the user changes the selection the selectionChanged() signal is emitted; similarly if the user changes a cell's value the valueChanged() signal is emitted. If the user right-clicks (or presses the appropriate platform-specific key sequence) the contextMenuRequested() signal is emitted. If the user drops a drag and drop object the dropped() signal is emitted with the drop event.
See also Advanced Widgets.
Specifies how the current cell (focus cell) is drawn.
Call setNumRows() and setNumCols() to set the table size before populating the table if you're using TQTableItems.
See also TQWidget::clearWFlags() and TQt::WidgetFlags.
If you're using TQTableItems to populate the table's cells, you can create TQTableItem, TQComboTableItem and TQCheckTableItem items and insert them into the table using setItem(). (See the notes on large tables for an alternative to using TQTableItems.)
See also TQWidget::clearWFlags() and TQt::WidgetFlags.
The default behaviour is to move from top to bottom, i.e. move to the cell beneath the cell being edited. Reimplement this function if you want different behaviour, e.g. moving from left to right.
Remember to call TQTableSelection::init() and TQTableSelection::expandTo() to make the selection valid (see also TQTableSelection::isActive(), or use the TQTableSelection(int,int,int,int) constructor).
See also numSelections, removeSelection(), and clearSelection().

If you don't use TQTableItems you may need to reimplement this function: see the notes on large tables.
See also clearCellWidget() and setCellWidget().
Example: chart/setdataform.cpp.
If you don't use TQTableItems you may need to reimplement this function: see the notes on large tables.
If you don't use TQTableItems you may need to reimplement this function: see the notes on large tables.
This function deletes the widget at row, col. Note that the widget is not deleted immediately; instead TQObject::deleteLater() is called on the widget to avoid problems with timing issues.
See also cellWidget() and setCellWidget().
See also removeSelection().
This signal is emitted when mouse button button is clicked. The cell where the event took place is at row, col, and the mouse's position is in mousePos.
See also TQt::ButtonState.
Example: chart/setdataform.cpp.
See also columnPos() and rowAt().
If you want to change the column order programmatically, call swapRows() or swapColumns();
See also TQHeader::indexChange() and rowIndexChanged().
Returns TRUE if columns can be moved by the user; otherwise returns FALSE. See the "columnMovingEnabled" property for details.
See also columnAt() and rowPos().
See also setColumnWidth() and rowHeight().
The focus is moved to the cell where the TQDragEnterEvent occurred.

Reimplemented from TQScrollView.
This signal is emitted when the user invokes a context menu with the right mouse button (or with a system-specific keypress). The cell where the event took place is at row, col. pos is the position where the context menu will appear in the global coordinate system. This signal is always emitted, even if the contents of the cell are disabled.
If initFromCell is TRUE, the editor is used to edit the current contents of the cell (so the editor widget should be initialized with this content). If initFromCell is FALSE, the content of the cell is replaced with the new content which the user entered into the widget created by this function.
The default functionality is as follows: if initFromCell is TRUE or the cell has a TQTableItem and the table item's TQTableItem::isReplaceable() is FALSE then the cell is asked to create an appropriate editor (using TQTableItem::createEditor()). Otherwise a TQLineEdit is used as the editor.
If you want to create your own editor for certain cells, implement a custom TQTableItem subclass and reimplement TQTableItem::createEditor().
If you are not using TQTableItems and you don't want to use a TQLineEdit as the default editor, subclass TQTable and reimplement this function with code like this:
TQTableItem *i = item( row, col );
if ( initFromCell || ( i && !i->isReplaceable() ) )
// If we had a TQTableItem ask the base class to create the editor
return TQTable::createEditor( row, col, initFromCell );
else
return ...(create your own editor)
Ownership of the editor widget is transferred to the caller.
If you reimplement this function return 0 for read-only cells. You will need to reimplement setCellContentFromEditor() to retrieve the data the user entered.
See also TQTableItem::createEditor().
This signal is emitted when the current cell has changed to row, col.
Example: chart/setdataform.cpp.
Returns the current column.
See also currentRow().
Example: chart/setdataform.cpp.
Returns the current row.
See also currentColumn().
Example: chart/setdataform.cpp.
See also numSelections.
This signal is emitted when mouse button button is double-clicked. The cell where the event took place is at row, col, and the mouse's position is in mousePos.
See also TQt::ButtonState.
See also setDragEnabled().
By default this function returns 0. You might reimplement it and create a TQDragObject depending on the selected items.
See also dropped().
Additionally, drawContents() highlights the current cell.
Reimplemented from TQScrollView.
This signal is emitted when a drop event occurred on the table.
e contains information about the drop.
If replace is TRUE the content of this cell will be replaced by the content of the editor when editing is finished, i.e. the user will be entering new data; otherwise the current content of the cell (if any) will be modified in the editor.
See also beginEdit().
See also TQTable::EditMode.
If the cell is not being edited or accept is FALSE the function returns and the cell's contents are left unchanged.
If accept is TRUE the content of the editor must be transferred to the relevant cell. If replace is TRUE the current content of this cell should be replaced by the content of the editor (this means removing the current TQTableItem of the cell and creating a new one for the cell). Otherwise (if possible) the content of the editor should just be set to the existing TQTableItem of this cell.
setCellContentFromEditor() is called to replace the contents of the cell with the contents of the cell's editor.
Finally clearCellWidget() is called to remove the editor widget.
See also setCellContentFromEditor() and beginEdit().
Returns how the current (focus) cell is drawn. See the "focusStyle" property for details.
See also showColumn() and hideRow().
See also showRow() and hideColumn().
This header contains the column labels.
To modify a column label use TQHeader::setLabel(), e.g.
horizontalHeader()->setLabel( 0, tr( "File" ) );
See also verticalHeader(), setTopMargin(), and TQHeader.
Examples: chart/setdataform.cpp, helpsystem/mainwindow.cpp, regexptester/regexptester.cpp, and table/small-table-demo/main.cpp.
This is useful, for example, if you have a sparse table and want to use a TQIntDict to map integers to the cells that are used.
See also insertRows() and removeColumn().
See also insertColumns() and removeRow().
If you don't use TQTableItems you may need to reimplement this function: see the notes on large tables.
See also hideColumn() and isRowHidden().
Whether a cell in this column is editable or read-only depends on the cell's EditType, and this setting: see TQTableItem::EditType.
See also setColumnReadOnly() and isRowReadOnly().
If full is FALSE (the default), 'column is selected' means that at least one cell in the column is selected. If full is TRUE, then 'column is selected' means every cell in the column is selected.
See also isRowSelected() and isSelected().
See also setColumnStretchable() and isRowStretchable().
See also TQTable::EditMode.
Returns TRUE if the table is read-only; otherwise returns FALSE. See the "readOnly" property for details.
See also hideRow() and isColumnHidden().
Whether a cell in this row is editable or read-only depends on the cell's EditType, and this setting: see TQTableItem::EditType.
See also setRowReadOnly() and isColumnReadOnly().
If full is FALSE (the default), 'row is selected' means that at least one cell in the row is selected. If full is TRUE, then 'row is selected' means every cell in the row is selected.
See also isColumnSelected() and isSelected().
See also setRowStretchable() and isColumnStretchable().
See also isRowSelected() and isColumnSelected().
If row or col are out of range or no content has been set for this cell, item() returns 0.
If you don't use TQTableItems you may need to reimplement this function: see the notes on large tables.
See also setItem().
Example: regexptester/regexptester.cpp.
Returns the number of columns in the table. See the "numCols" property for details.
Reimplemented in TQDataTable.
Returns the number of rows in the table. See the "numRows" property for details.
Reimplemented in TQDataTable.
Returns the number of selections. See the "numSelections" property for details.
If selected is TRUE the cell is highlighted.
cg is the colorgroup which should be used to draw the cell content.
If you want to draw custom cell content, for example right-aligned text, you must either reimplement paintCell(), or subclass TQTableItem and reimplement TQTableItem::paint() to do the custom drawing.
If you're using a TQTableItem subclass, for example, to store a data structure, then reimplementing TQTableItem::paint() may be the best approach. For data you want to draw immediately, e.g. data retrieved from a database, it is probably best to reimplement paintCell(). Note that if you reimplement paintCell(), i.e. don't use TQTableItems, you must reimplement other functions: see the notes on large tables.
Note that the painter is not clipped by default in order to get maximum efficiency. If you want clipping, use code like this:
p->setClipRect( cellRect(row, col), TQPainter::CoordPainter );
//... your drawing code
p->setClipping( FALSE );
Use the other paintCell() function. This function is only included for backwards compatibilty.
paintEmptyArea() is invoked by drawContents() to erase or fill unused areas.
The painter p is already translated to the cell's origin, while cr specifies the cell's geometry in content coordinates.
See also setPixmap().
Example: chart/setdataform.cpp.
This signal is emitted when mouse button button is pressed. The cell where the event took place is at row, col, and the mouse's position is in mousePos.
See also TQt::ButtonState.
See also removeColumns(), hideColumn(), insertColumns(), and removeRow().
The array passed in must only contain valid columns (in the range from 0 to numCols() - 1) with no duplicates, and must be sorted in ascending order. Also clears the selection(s).
See also removeColumn(), insertColumns(), and removeRows().
See also hideRow(), insertRows(), removeColumn(), and removeRows().
The array passed in must only contain valid rows (in the range from 0 to numRows() - 1) with no duplicates, and must be sorted in ascending order. Also clears the selection(s).
See also removeRow(), insertRows(), and removeColumns().
See also addSelection() and numSelections.
Removes selection number num from the table.
See also numSelections, addSelection(), and clearSelection().
If you don't use TQTableItems you should reimplement this as an empty method to avoid wasting memory. See the notes on large tables for further details.
See also rowPos() and columnAt().
See also setRowHeight() and columnWidth().
Example: table/small-table-demo/main.cpp.
If you want to change the order programmatically, call swapRows() or swapColumns();
See also TQHeader::indexChange() and columnIndexChanged().
Returns TRUE if rows can be moved by the user; otherwise returns FALSE. See the "rowMovingEnabled" property for details.
See also rowAt() and columnPos().
See also TQTableSelection.
See also TQTableSelection.
See also TQTableSelection.
This signal is emitted whenever a selection changes.
See also TQTableSelection.
Returns the current selection mode. See the "selectionMode" property for details.
If there already exists a TQTableItem for the cell, it calls TQTableItem::setContentFromEditor() on this TQTableItem.
If, for example, you want to create different TQTableItems depending on the contents of the editor, you might reimplement this function.
If you want to work without TQTableItems, you will need to reimplement this function to save the data the user entered into your data structure. (See the notes on large tables.)
See also TQTableItem::setContentFromEditor() and createEditor().
By default widgets are inserted into a vector with numRows() * numCols() elements. In very large tables you will probably want to store the widgets in a data structure that consumes less memory (see the notes on large tables). To support the use of your own data structure this function calls insertWidget() to add the widget to the internal data structure. To use your own data structure reimplement insertWidget(), cellWidget() and clearCellWidget().
Cell widgets are created dynamically with the new operator. The cell widgets are destroyed automatically once the table is destroyed; the table takes ownership of the widget when using setCellWidget.
Example: chart/setdataform.cpp.
Sets whether columns can be moved by the user to b. See the "columnMovingEnabled" property for details.
Whether a cell in this column is editable or read-only depends on the cell's EditType, and this setting: see TQTableItem::EditType.
See also isColumnReadOnly(), setRowReadOnly(), and readOnly.
Example: chart/setdataform.cpp.
If the table widget's width decreases or increases stretchable columns will grow narrower or wider to fit the space available as completely as possible. The user cannot manually resize stretchable columns.
See also isColumnStretchable(), setRowStretchable(), and adjustColumn().
See also columnWidth() and setRowHeight().
Example: chart/setdataform.cpp.
Reimplemented in TQDataTable.
See also currentRow() and currentColumn().
See also EditMode.
Sets how the current (focus) cell is drawn to fs. See the "focusStyle" property for details.
If you don't use TQTableItems you may need to reimplement this function: see the notes on large tables.
See also item() and takeItem().
Examples: helpsystem/mainwindow.cpp and table/small-table-demo/main.cpp.
The verticalHeader(), which displays row labels, occupies this margin.
In an Arabic or Hebrew localization, the verticalHeader() will appear on the right side of the table, and this call will set the right margin.
See also leftMargin(), setTopMargin(), and verticalHeader().
Example: regexptester/regexptester.cpp.
Sets the number of columns in the table to r. See the "numCols" property for details.
Sets the number of rows in the table to r. See the "numRows" property for details.
If the cell does not contain a table item a TQTableItem is created with an EditType of OnTyping, otherwise the existing table item's pixmap (if any) is replaced with pix.
Note that TQComboTableItems and TQCheckTableItems don't show pixmaps.
See also pixmap(), setText(), setItem(), and TQTableItem::setPixmap().
Examples: chart/setdataform.cpp and table/small-table-demo/main.cpp.
Sets whether the table is read-only to b. See the "readOnly" property for details.
See also rowHeight() and setColumnWidth().
Sets whether rows can be moved by the user to b. See the "rowMovingEnabled" property for details.
Whether a cell in this row is editable or read-only depends on the cell's EditType, and this setting: see TQTableItem::EditType.
See also isRowReadOnly(), setColumnReadOnly(), and readOnly.
If the table widget's height decreases or increases stretchable rows will grow shorter or taller to fit the space available as completely as possible. The user cannot manually resize stretchable rows.
See also isRowStretchable() and setColumnStretchable().
Sets the current selection mode to mode. See the "selectionMode" property for details.
Sets whether the table's grid is displayed to b. See the "showGrid" property for details.
Sets whether a click on the header of a column sorts that column to b. See the "sorting" property for details.
If the cell does not contain a table item a TQTableItem is created with an EditType of OnTyping, otherwise the existing table item's text (if any) is replaced with text.
See also text(), setPixmap(), setItem(), and TQTableItem::setText().
Examples: chart/setdataform.cpp, helpsystem/mainwindow.cpp, regexptester/regexptester.cpp, and table/small-table-demo/main.cpp.
The horizontalHeader(), which displays column labels, occupies this margin.
See also topMargin() and setLeftMargin().
Example: regexptester/regexptester.cpp.
See also hideColumn() and showRow().
Returns TRUE if the table's grid is displayed; otherwise returns FALSE. See the "showGrid" property for details.
See also hideRow() and showColumn().
If wholeRows is TRUE, entire rows are sorted using swapRows(); otherwise only cells in the column are sorted using swapCells().
Note that if you are not using TQTableItems you will need to reimplement swapRows() and swapCells(). (See the notes on large tables.)
See also swapRows().
Example: table/statistics/statistics.cpp.
Reimplemented in TQDataTable.
Returns TRUE if a click on the header of a column sorts that column; otherwise returns FALSE. See the "sorting" property for details.
Usually you don't need to call or reimplement this function yourself.
See also dragObject().
This function is also called when the table is sorted.
If you don't use TQTableItems and want your users to be able to swap cells, you will need to reimplement this function. (See the notes on large tables.)
See also swapColumns() and swapRows().
This function is used to swap the positions of two columns. It is called when the user changes the order of columns (see setColumnMovingEnabled(), and when columns are sorted.
If you don't use TQTableItems and want your users to be able to swap columns you will need to reimplement this function. (See the notes on large tables.)
If swapHeader is TRUE, the columns' header contents is also swapped.
See also swapCells().
This function is used to swap the positions of two rows. It is called when the user changes the order of rows (see setRowMovingEnabled()), and when rows are sorted.
If you don't use TQTableItems and want your users to be able to swap rows, e.g. for sorting, you will need to reimplement this function. (See the notes on large tables.)
If swapHeader is TRUE, the rows' header contents is also swapped.
This function will not update the TQTable, you will have to do this manually, e.g. by calling updateContents().
See also swapColumns() and swapCells().
Use this function if you want to move an item from one cell in a table to another, or to move an item from one table to another, reinserting the item with setItem().
If you want to exchange two cells use swapCells().
See also setText() and setPixmap().
Example: chart/setdataform.cpp.
Reimplemented in TQDataTable.
This signal is emitted when the user changed the value in the cell at row, col.
Example: chart/setdataform.cpp.
