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 tquick
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-&gt;<a href="#setLabel">setLabel</a>( "File Operations" );
        fileOpenAction-&gt;<a href="ntqaction.html#addTo">addTo</a>( fileTools );
        fileSaveAction-&gt;<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, '&#187;') 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.

<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQToolBar"></a>TQToolBar::TQToolBar ( const&nbsp;<a href="ntqstring.html">TQString</a>&nbsp;&amp;&nbsp;label, <a href="ntqmainwindow.html">TQMainWindow</a>&nbsp;*, ToolBarDock = DockTop, bool&nbsp;newLine = FALSE, const&nbsp;char&nbsp;*&nbsp;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&nbsp;<a href="ntqstring.html">TQString</a>&nbsp;&amp;&nbsp;label, <a href="ntqmainwindow.html">TQMainWindow</a>&nbsp;*&nbsp;mainWindow, <a href="ntqwidget.html">TQWidget</a>&nbsp;*&nbsp;parent, bool&nbsp;newLine = FALSE, const&nbsp;char&nbsp;*&nbsp;name = 0, WFlags&nbsp;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>&nbsp;*&nbsp;parent = 0, const&nbsp;char&nbsp;*&nbsp;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
retquiring 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>&nbsp;* <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&nbsp;<a href="ntqstring.html">TQString</a>&nbsp;&amp; )<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>&nbsp;*&nbsp;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>().
