The TQToolBar class provides a movable panel containing
widgets such as tool buttons.
< p >
< p > A toolbar is a panel that contains a set of controls, usually
represented by small icons. It's purpose is to provide quick
access to frequently used commands or options. Within a
< a href = "ntqmainwindow.html" > TQMainWindow< / a > the user can drag toolbars within and between the
< a href = "ntqdockarea.html" > dock areas< / a > . Toolbars can also be dragged
out of any dock area to float freely as top-level windows.
< p > TQToolBar is a specialization of < a href = "ntqdockwindow.html" > TQDockWindow< / a > , and so provides all
the functionality of a TQDockWindow.
< p > To use TQToolBar you simply create a TQToolBar as a child of a
TQMainWindow, create a number of < a href = "ntqtoolbutton.html" > TQToolButton< / a > widgets (or other
widgets) in left to right (or top to bottom) order and call
< a href = "#addSeparator" > addSeparator< / a > () when you want a separator. When a toolbar is
floated the caption used is the label given in the constructor
call. This can be changed with < a href = "#setLabel" > setLabel< / a > ().
< p >
< pre > TQToolBar * fileTools = new TQToolBar( this, "file operations" );
fileTools-> < a href = "#setLabel" > setLabel< / a > ( "File Operations" );
fileOpenAction-> < a href = "ntqaction.html#addTo" > addTo< / a > ( fileTools );
fileSaveAction-> < a href = "ntqaction.html#addTo" > addTo< / a > ( fileTools );
< / pre >
< p > This extract from the < a href = "simple-application-example.html" > application/application.cpp< / a > example shows
the creation of a new toolbar as a child of a < a href = "ntqmainwindow.html" > TQMainWindow< / a > and
adding two TQActions.
< p > You may use most widgets within a toolbar, with TQToolButton and
< a href = "ntqcombobox.html" > TQComboBox< / a > being the most common.
< p > If you create a new widget on an already visible TQToolBar, this
widget will automatically become visible without needing a < a href = "ntqwidget.html#show" > show< / a > ()
call. (This differs from every other TQt widget container. We
recommend calling show() anyway since we hope to fix this anomaly
in a future release.)
< p > TQToolBars, like TQDockWindows, are located in < a href = "ntqdockarea.html" > TQDockArea< / a > s or
float as top-level windows. TQMainWindow provides four TQDockAreas
(top, left, right and bottom). When you create a new toolbar (as
in the example above) as a child of a TQMainWindow the toolbar will
be added to the top dock area. You can move it to another dock
area (or float it) by calling < a href = "ntqmainwindow.html#moveDockWindow" > TQMainWindow::moveDockWindow< / a > (). TQDock
areas lay out their windows in < a href = "ntqdockarea.html#lines" > Lines< / a > .
< p > If the main window is resized so that the area occupied by the
toolbar is too small to show all its widgets a little arrow button
(which looks like a right-pointing chevron, '» ') will appear
at the right or bottom of the toolbar depending on its
orientation. Clicking this button pops up a menu that shows the
'overflowing' items. TQToolButtons are represented in the menu using
their textLabel property, other < a href = "ntqbutton.html" > TQButton< / a > subclasses are represented
using their text property, and TQComboBoxes are represented as submenus,
with the caption text being used in the submenu item.
< p > Usually a toolbar will get precisely the space it needs. However,
with < a href = "ntqdockwindow.html#setHorizontalStretchable" > setHorizontalStretchable< / a > (), < a href = "ntqdockwindow.html#setVerticalStretchable" > setVerticalStretchable< / a > () or
< a href = "#setStretchableWidget" > setStretchableWidget< / a > () you can tell the main window to expand the
toolbar to fill all available space in the specified orientation.
< p > The toolbar arranges its buttons either horizontally or vertically
(see < a href = "ntqdockwindow.html#orientation" > orientation< / a > () for details). Generally, < a href = "ntqdockarea.html" > TQDockArea< / a > will set the
orientation correctly for you, but you can set it yourself with
< a href = "ntqdockwindow.html#setOrientation" > setOrientation< / a > () and track any changes by connecting to the
< a href = "ntqdockwindow.html#orientationChanged" > orientationChanged< / a > () signal.
< p > You can use the < a href = "#clear" > clear< / a > () method to remove all items from a toolbar.

< h3 class = fn > < a name = "TQToolBar" > < / a > TQToolBar::TQToolBar ( const < a href = "ntqstring.html" > TQString< / a > & label, < a href = "ntqmainwindow.html" > TQMainWindow< / a > *, ToolBarDock = DockTop, bool newLine = FALSE, const char * name = 0 )
< / 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 >
< h3 class = fn > < a name = "TQToolBar-2" > < / a > TQToolBar::TQToolBar ( const < a href = "ntqstring.html" > TQString< / a > & label, < a href = "ntqmainwindow.html" > TQMainWindow< / a > * mainWindow, < a href = "ntqwidget.html" > TQWidget< / a > * parent, bool newLine = FALSE, const char * name = 0, WFlags f = 0 )
< / h3 >
Constructs an empty horizontal toolbar.
< p > The toolbar is called < em > name< / em > and is a child of < em > parent< / em > and is
managed by < em > mainWindow< / em > . The < em > label< / em > and < em > newLine< / em > parameters
are passed straight to < a href = "ntqmainwindow.html#addDockWindow" > TQMainWindow::addDockWindow< / a > (). < em > name< / em > and
the widget flags < em > f< / em > are passed on to the < a href = "ntqdockwindow.html" > TQDockWindow< / a > constructor.
< p > Use this constructor if you want to create torn-off (undocked,
floating) toolbars or toolbars in the < a href = "ntqstatusbar.html" > status
bar< / a > .
< h3 class = fn > < a name = "TQToolBar-3" > < / a > TQToolBar::TQToolBar ( < a href = "ntqmainwindow.html" > TQMainWindow< / a > * parent = 0, const char * name = 0 )
< / h3 >
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
< p > Constructs an empty toolbar called < em > name< / em > , with parent < em > parent< / em > ,
in its < em > parent< / em > 's top dock area, without any label and without
requiring a newline.
< h3 class = fn > void < a name = "addSeparator" > < / a > TQToolBar::addSeparator ()
< / h3 >
Adds a separator to the right/bottom of the toolbar.
< p > Examples: < a href = "canvas-chart-example.html#x2894" > chart/chartform.cpp< / a > , < a href = "fileiconview-example.html#x895" > fileiconview/mainwindow.cpp< / a > , < a href = "helpviewer-example.html#x1033" > helpviewer/helpwindow.cpp< / a > , < a href = "qfd-example.html#x2010" > qfd/fontdisplayer.cpp< / a > , and < a href = "scribble-example.html#x943" > scribble/scribble.cpp< / a > .
< h3 class = fn > void < a name = "clear" > < / a > TQToolBar::clear ()< tt > [virtual]< / tt >
< / h3 >
Deletes all the toolbar's child widgets.
< h3 class = fn > < a href = "ntqstring.html" > TQString< / a > < a name = "label" > < / a > TQToolBar::label () const
< / h3 > < p > Returns the toolbar's label.
See the < a href = "ntqtoolbar.html#label-prop" > "label"< / a > property for details.
< h3 class = fn > < a href = "ntqmainwindow.html" > TQMainWindow< / a > * < a name = "mainWindow" > < / a > TQToolBar::mainWindow () const
< / h3 >
Returns a pointer to the < a href = "ntqmainwindow.html" > TQMainWindow< / a > which manages this toolbar.
< h3 class = fn > void < a name = "setLabel" > < / a > TQToolBar::setLabel ( const < a href = "ntqstring.html" > TQString< / a > & )< tt > [virtual]< / tt >
< / h3 > < p > Sets the toolbar's label.
See the < a href = "ntqtoolbar.html#label-prop" > "label"< / a > property for details.
< h3 class = fn > void < a name = "setStretchableWidget" > < / a > TQToolBar::setStretchableWidget ( < a href = "ntqwidget.html" > TQWidget< / a > * w )< tt > [virtual]< / tt >
< / h3 >
Sets the widget < em > w< / em > to be expanded if this toolbar is requested
to stretch.
< p > The request to stretch might occur because < a href = "ntqmainwindow.html" > TQMainWindow< / a >
right-justifies the dock area the toolbar is in, or because this
toolbar's < a href = "ntqdockwindow.html#isVerticalStretchable" > isVerticalStretchable< / a > () or < a href = "ntqdockwindow.html#isHorizontalStretchable" > isHorizontalStretchable< / a > () is
set to TRUE.
< p > If you call this function and the toolbar is not yet stretchable,
setStretchable() is called.
< p > < p > See also < a href = "ntqmainwindow.html#rightJustification-prop" > TQMainWindow::rightJustification< / a > , < a href = "ntqdockwindow.html#setVerticalStretchable" > setVerticalStretchable< / a > (), and < a href = "ntqdockwindow.html#setHorizontalStretchable" > setHorizontalStretchable< / a > ().
< p > Examples: < a href = "fileiconview-example.html#x896" > fileiconview/mainwindow.cpp< / a > and < a href = "helpviewer-example.html#x1034" > helpviewer/helpwindow.cpp< / a > .
< hr > < h2 > Property Documentation< / h2 >
< h3 class = fn > < a href = "ntqstring.html" > TQString< / a > < a name = "label-prop" > < / a > label< / h3 >
< p > This property holds the toolbar's label.
< p > If the toolbar is floated the label becomes the toolbar window's
caption. There is no default label text.
< p > Set this property's value with < a href = "#setLabel" > setLabel< / a > () and get this property's value with < a href = "#label" > label< / a > ().
