< hr > < a name = "details" > < / a > < h2 > Detailed Description< / h2 >
< p > The TQGridLayout class lays out widgets in a grid.
< p >
< p > TQGridLayout takes the space made available to it (by its parent
layout or by the < a href = "ntqlayout.html#mainWidget" > mainWidget< / a > ()), divides it up into rows and
columns, and puts each widget it manages into the correct cell.
< p > Columns and rows behave identically; we will discuss columns, but
there are equivalent functions for rows.
< p > Each column has a minimum width and a < a href = "layout.html#stretch-factor" > stretch factor< / a > . The minimum
width is the greatest of that set using < a href = "#addColSpacing" > addColSpacing< / a > () and the
minimum width of each widget in that column. The stretch factor is
set using < a href = "#setColStretch" > setColStretch< / a > () and determines how much of the available
space the column will get over and above its necessary minimum.
< p > Normally, each managed widget or layout is put into a cell of its
own using < a href = "#addWidget" > addWidget< / a > (), < a href = "#addLayout" > addLayout< / a > () or by the < a href = "ntqlayout.html#setAutoAdd" > auto-add facility< / a > . It is also
possible for a widget to occupy multiple cells using
< a href = "#addMultiCellWidget" > addMultiCellWidget< / a > (). If you do this, TQGridLayout will guess how
to distribute the size over the columns/rows (based on the stretch
factors).
< p > To remove a widget from a layout, call < a href = "ntqlayout.html#remove" > remove< / a > (). Calling
< a href = "tqwidget.html#hide" > TQWidget::hide< / a > () on a widget also effectively removes the widget
from the layout until < a href = "tqwidget.html#show" > TQWidget::show< / a > () is called.
< p > This illustration shows a fragment of a dialog with a five-column,
three-row grid (the grid is shown overlaid in magenta):
< p > < center > < img src = "gridlayout.png" > < / center >
< p > Columns 0, 2 and 4 in this dialog fragment are made up of a
< a href = "ntqlabel.html" > TQLabel< / a > , a < a href = "ntqlineedit.html" > TQLineEdit< / a > , and a < a href = "ntqlistbox.html" > TQListBox< / a > . Columns 1 and 3 are
placeholders made with < a href = "#addColSpacing" > addColSpacing< / a > (). Row 0 consists of three
TQLabel objects, row 1 of three TQLineEdit objects and row 2 of
three TQListBox objects. We used placeholder columns (1 and 3) to
get the right amount of space between the columns.
< p > Note that the columns and rows are not equally wide or tall. If
you want two columns to have the same width, you must set their
minimum widths and stretch factors to be the same yourself. You do
this using addColSpacing() and < a href = "#setColStretch" > setColStretch< / a > ().
< p > If the TQGridLayout is not the top-level layout (i.e. does not
manage all of the widget's area and children), you must add it to
its parent layout when you create it, but before you do anything
with it. The normal way to add a layout is by calling
parentLayout-> addLayout().
< p > Once you have added your layout you can start putting widgets and
other layouts into the cells of your grid layout using
< a href = "#addWidget" > addWidget< / a > (), < a href = "#addLayout" > addLayout< / a > () and < a href = "#addMultiCellWidget" > addMultiCellWidget< / a > ().
< p > TQGridLayout also includes two margin widths: the border and the
spacing. The border is the width of the reserved space along each
of the TQGridLayout's four sides. The spacing is the width of the
automatically allocated spacing between neighboring boxes.
< p > Both the border and the spacing are parameters of the constructor
and default to 0.

< / h3 >
Constructs a new TQGridLayout with < em > nRows< / em > rows, < em > nCols< / em > columns
and parent widget, < em > parent< / em > . < em > parent< / em > may not be 0. The grid
layout is called < em > name< / em > .
< p > < em > margin< / em > is the number of pixels between the edge of the widget
and its managed children. < em > space< / em > is the default number of pixels
between cells. If < em > space< / em > is -1, the value of < em > margin< / em > is used.
< h3 class = fn > < a name = "TQGridLayout-2" > < / a > TQGridLayout::TQGridLayout ( int nRows = 1, int nCols = 1, int spacing = -1, const char * name = 0 )
< / h3 >
Constructs a new grid with < em > nRows< / em > rows and < em > nCols< / em > columns. If
< em > spacing< / em > is -1, this TQGridLayout inherits its parent's
< a href = "ntqlayout.html#spacing" > spacing< / a > (); otherwise < em > spacing< / em > is used. The grid layout is called
< em > name< / em > .
< p > You must insert this grid into another layout. You can insert
widgets and layouts into this layout at any time, but laying out
will not be performed before this is inserted into another layout.
< h3 class = fn > < a name = "TQGridLayout-3" > < / a > TQGridLayout::TQGridLayout ( < a href = "ntqlayout.html" > TQLayout< / a > * parentLayout, int nRows = 1, int nCols = 1, int spacing = -1, const char * name = 0 )
< / h3 >
Constructs a new grid that is placed inside < em > parentLayout< / em > with
< em > nRows< / em > rows and < em > nCols< / em > columns. If < em > spacing< / em > is -1, this
TQGridLayout inherits its parent's < a href = "ntqlayout.html#spacing" > spacing< / a > (); otherwise < em > spacing< / em >
is used. The grid layout is called < em > name< / em > .
< p > This grid is placed according to < em > parentLayout< / em > 's default
placement rules.
< h3 class = fn > < a name = "~TQGridLayout" > < / a > TQGridLayout::~TQGridLayout ()
< / h3 >
Destroys the grid layout. Geometry management is terminated if
this is a top-level grid.
< p > The layout's widgets aren't destroyed.
< h3 class = fn > void < a name = "add" > < / a > TQGridLayout::add ( < a href = "qlayoutitem.html" > TQLayoutItem< / a > * item, int row, int col )< tt > [protected]< / tt >
< / h3 >
Adds < em > item< / em > at position < em > row< / em > , < em > col< / em > . The layout takes
ownership of the < em > item< / em > .
< h3 class = fn > void < a name = "addColSpacing" > < / a > TQGridLayout::addColSpacing ( int col, int minsize )
< / h3 >
< b > This function is obsolete.< / b > It is provided to keep old source working. We strongly advise against using it in new code.
< p > Sets the minimum width of column < em > col< / em > to < em > minsize< / em > pixels.
< p > Use < a href = "#setColSpacing" > setColSpacing< / a > () instead.
< h3 class = fn > void < a name = "addItem" > < / a > TQGridLayout::addItem ( < a href = "qlayoutitem.html" > TQLayoutItem< / a > * item, int row, int col )
< / h3 >
Adds < em > item< / em > at position < em > row< / em > , < em > col< / em > . The layout takes
ownership of the < em > item< / em > .
< h3 class = fn > void < a name = "addItem-2" > < / a > TQGridLayout::addItem ( < a href = "qlayoutitem.html" > TQLayoutItem< / a > * item )< tt > [virtual]< / tt >
< / h3 >
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
< p > Adds < em > item< / em > to the next free position of this layout.
< p > Reimplemented from < a href = "ntqlayout.html#addItem" > TQLayout< / a > .
< h3 class = fn > void < a name = "addLayout" > < / a > TQGridLayout::addLayout ( < a href = "ntqlayout.html" > TQLayout< / a > * layout, int row, int col )
< / h3 >
Places the < em > layout< / em > at position (< em > row< / em > , < em > col< / em > ) in the grid. The
top-left position is (0, 0).
< p > < em > layout< / em > becomes a child of the grid layout.
< p > When a layout is constructed with another layout as its parent,
you don't need to call < a href = "#addLayout" > addLayout< / a > (); the child layout is
automatically added to the parent layout as it is constructed.
< p > < p > See also < a href = "#addMultiCellLayout" > addMultiCellLayout< / a > ().
< p > Examples: < a href = "listbox-example.html#x1430" > listbox/listbox.cpp< / a > , < a href = "progressbar-example.html#x964" > progressbar/progressbar.cpp< / a > , < a href = "tutorial1-10.html#x2365" > t10/main.cpp< / a > , and < a href = "tutorial1-13.html#x2413" > t13/gamebrd.cpp< / a > .

< / h3 >
Adds the < em > item< / em > to the cell grid, spanning multiple rows/columns.
< p > The cell will span from < em > fromRow< / em > , < em > fromCol< / em > to < em > toRow< / em > , < em > toCol< / em > . Alignment is specified by < em > alignment< / em > , which is a bitwise
OR of < a href = "ntqt.html#AlignmentFlags-enum" > TQt::AlignmentFlags< / a > values. The default alignment is 0,
which means that the widget fills the entire cell.
< h3 class = fn > void < a name = "addMultiCellLayout" > < / a > TQGridLayout::addMultiCellLayout ( < a href = "ntqlayout.html" > TQLayout< / a > * layout, int fromRow, int toRow, int fromCol, int toCol, int alignment = 0 )

< h3 class = fn > void < a name = "addWidget" > < / a > TQGridLayout::addWidget ( < a href = "tqwidget.html" > TQWidget< / a > * w, int row, int col, int alignment = 0 )
< / h3 >
Adds the widget < em > w< / em > to the cell grid at < em > row< / em > , < em > col< / em > . The
top-left position is (0, 0) by default.
< p > Alignment is specified by < em > alignment< / em > , which is a bitwise OR of

< h3 class = fn > < a href = "ntqrect.html" > TQRect< / a > < a name = "cellGeometry" > < / a > TQGridLayout::cellGeometry ( int row, int col ) const
< / h3 >
Returns the geometry of the cell with row < em > row< / em > and column < em > col< / em >
in the grid. Returns an invalid rectangle if < em > row< / em > or < em > col< / em > is
outside the grid.
< p > < b > Warning:< / b > in the current version of TQt this function does not
return valid results until < a href = "#setGeometry" > setGeometry< / a > () has been called, i.e.
after the < a href = "ntqlayout.html#mainWidget" > mainWidget< / a > () is visible.
< h3 class = fn > int < a name = "colSpacing" > < / a > TQGridLayout::colSpacing ( int col ) const
< / h3 >
Returns the column spacing for column < em > col< / em > .
< p > < p > See also < a href = "#setColSpacing" > setColSpacing< / a > ().
< h3 class = fn > int < a name = "colStretch" > < / a > TQGridLayout::colStretch ( int col ) const
< / h3 >
Returns the < a href = "layout.html#stretch-factor" > stretch factor< / a > for column < em > col< / em > .
< p > < p > See also < a href = "#setColStretch" > setColStretch< / a > ().
< h3 class = fn > void < a name = "expand" > < / a > TQGridLayout::expand ( int nRows, int nCols )
< / h3 >
Expands this grid so that it will have < em > nRows< / em > rows and < em > nCols< / em >
columns. Will not shrink the grid. You should not need to call
this function because TQGridLayout expands automatically as new
items are inserted.
< h3 class = fn > < a href = "ntqsizepolicy.html#ExpandData-enum" > TQSizePolicy::ExpandData< / a > < a name = "expanding" > < / a > TQGridLayout::expanding () const< tt > [virtual]< / tt >

Returns whether this layout can make use of more space than
< a href = "#sizeHint" > sizeHint< / a > (). A value of < a href = "ntqt.html#Orientation-enum" > Vertical< / a > or < a href = "ntqt.html#Orientation-enum" > Horizontal< / a > means that it wants
to grow in only one dimension, whereas < tt > BothDirections< / tt > means that
it wants to grow in both dimensions.
< p > Reimplemented from < a href = "ntqlayout.html#expanding" > TQLayout< / a > .

< / h3 >
Searches for widget < em > w< / em > in this layout (not including child
layouts). If < em > w< / em > is found, it sets < tt > < em> row< /em> < / tt > and < tt > < em> col< /em> < / tt > to
the row and column and returns TRUE; otherwise returns FALSE.
< p > Note: if a widget spans multiple rows/columns, the top-left cell
is returned.
< h3 class = fn > bool < a name = "hasHeightForWidth" > < / a > TQGridLayout::hasHeightForWidth () const< tt > [virtual]< / tt >
< / h3 >
Returns TRUE if this layout's preferred height depends on its
width; otherwise returns FALSE.
< p > Reimplemented from < a href = "qlayoutitem.html#hasHeightForWidth" > TQLayoutItem< / a > .
< h3 class = fn > int < a name = "heightForWidth" > < / a > TQGridLayout::heightForWidth ( int w ) const< tt > [virtual]< / tt >
