<div class="descr">
<h2>Detailed Description</h2>
<p>The Q3MainWindow class provides a main application window, with a menu bar, dock windows (e.g. for toolbars), and a status bar.</p>
<p>Main windows are most often used to provide menus, toolbars and a status bar around a large central widget, such as a text edit, drawing canvas or <a href="qworkspace.html" class="obsolete">QWorkspace</a> (for MDI applications). Q3MainWindow is usually subclassed since this makes it easier to encapsulate the central widget, menus and toolbars as well as the window's state. Subclassing makes it possible to create the slots that are called when the user clicks menu items or toolbar buttons.</p>
<p>We'll briefly review adding menu items and toolbar buttons then describe the facilities of Q3MainWindow itself.</p>
<pre class="cpp"> <span class="type">Q3MainWindow</span> <span class="operator">*</span>mw <span class="operator">=</span> <span class="keyword">new</span> <span class="type">Q3MainWindow</span>;
<span class="type"><a href="qtextedit.html">QTextEdit</a></span> <span class="operator">*</span>edit <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qtextedit.html">QTextEdit</a></span>(mw<span class="operator">,</span> <span class="string">"editor"</span>);

mw<span class="operator">-</span><span class="operator">></span><a href="q3mainwindow.html#setCentralWidget">setCentralWidget</a>(edit);
mw<span class="operator">-</span><span class="operator">></span><a href="qwidget.html#show">show</a>();</pre>
<p>Q3MainWindows may be created in their own right as shown above. The central widget is set with <a href="q3mainwindow.html#setCentralWidget">setCentralWidget</a>(). Popup menus can be added to the default menu bar, widgets can be added to the status bar, toolbars and dock windows can be added to any of the dock areas.</p>
<p>The main window will take care of the dock areas, and the geometry of the central widget, but all other aspects of the central widget are left to you. Q3MainWindow automatically detects the creation of a menu bar or status bar if you specify the Q3MainWindow as parent, or you can use the provided <a href="q3mainwindow.html#menuBar">menuBar</a>() and <a href="q3mainwindow.html#statusBar">statusBar</a>() functions. The functions <a href="q3mainwindow.html#menuBar">menuBar</a>() and <a href="q3mainwindow.html#statusBar">statusBar</a>() create a suitable widget if one doesn't exist, and update the window's layout to make space.</p>
<p>New dock windows and toolbars can be added to a Q3MainWindow using <a href="q3mainwindow.html#addDockWindow">addDockWindow</a>(). <a href="qt-qt3.html#Dock-enum">Qt::Dock</a> windows can be moved using <a href="q3mainwindow.html#moveDockWindow">moveDockWindow</a>() and removed with <a href="q3mainwindow.html#removeDockWindow">removeDockWindow</a>(). Q3MainWindow allows default dock window (toolbar) docking in all its dock areas (<tt>Top</tt>, <tt>Left</tt>, <tt>Right</tt>, <tt>Bottom</tt>). You can use <a href="q3mainwindow.html#setDockEnabled">setDockEnabled</a>() to enable and disable docking areas for dock windows. When adding or moving dock windows you can specify their 'edge' (dock area). The currently available edges are: <tt>Top</tt>, <tt>Left</tt>, <tt>Right</tt>, <tt>Bottom</tt>, <tt>Minimized</tt> (effectively a 'hidden' dock area) and <tt>TornOff</tt> (floating). See <a href="qt-qt3.html#Dock-enum">Qt::Dock</a> for an explanation of these areas. Note that the *ToolBar functions are included for backward compatibility; all new code should use the *DockWindow functions. <a href="porting4.html#qtoolbar">QToolbar</a> is a subclass of <a href="q3dockwindow.html">Q3DockWindow</a> so all functions that work with dock windows work on toolbars in the same way.</p>
<a name="dwm"></a><p>If the user clicks the close button, then the dock window is hidden. A dock window can be hidden or unhidden by the user by right clicking a dock area and clicking the name of the relevant dock window on the pop up dock window menu. This menu lists the names of every dock window; visible dock windows have a tick beside their names. The dock window menu is created automatically as required by <a href="q3mainwindow.html#createDockWindowMenu">createDockWindowMenu</a>(). Since it may not always be appropriate for a dock window to appear on this menu the <a href="q3mainwindow.html#setAppropriate">setAppropriate</a>() function is used to inform the main window whether or not the dock window menu should include a particular dock window. Double clicking a dock window handle (usually on the left-hand side of the dock window) undocks (floats) the dock window. Double clicking a floating dock window's title bar will dock the floating dock window. (See also <a href="q3mainwindow.html#DockWindows-enum">Q3MainWindow::DockWindows</a>.)</p>
<p>Some functions change the appearance of a Q3MainWindow globally:</p>
<ul>
<li><a href="q3dockwindow.html#setHorizontalStretchable">Q3DockWindow::setHorizontalStretchable</a>() and <a href="q3dockwindow.html#setVerticalStretchable">Q3DockWindow::setVerticalStretchable</a>() are used to make specific dock windows or toolbars stretchable.</li>
<li><a href="q3mainwindow.html#usesBigPixmaps-prop">setUsesBigPixmaps</a>() is used to set whether tool buttons should draw small or large pixmaps (see <a href="qicon.html">QIcon</a> for more information).</li>
<li><a href="q3mainwindow.html#usesTextLabel-prop">setUsesTextLabel</a>() is used to set whether tool buttons should display a textual label in addition to pixmaps (see <a href="qtoolbutton.html">QToolButton</a> for more information).</li>
</ul>
<p>The user can drag dock windows into any enabled docking area. <a href="qt-qt3.html#Dock-enum">Qt::Dock</a> windows can also be dragged <i>within</i> a docking area, for example to rearrange the order of some toolbars. <a href="qt-qt3.html#Dock-enum">Qt::Dock</a> windows can also be dragged outside any docking area (undocked or 'floated'). Being able to drag dock windows can be enabled (the default) and disabled using <a href="q3mainwindow.html#dockWindowsMovable-prop">setDockWindowsMovable</a>().</p>
<p>The <tt>Minimized</tt> edge is a hidden dock area. If this dock area is enabled the user can hide (minimize) a dock window or show (restore) a minimized dock window by clicking the dock window handle. If the user hovers the mouse cursor over one of the handles, the caption of the dock window is displayed in a tool tip (see <a href="q3dockwindow.html#windowTitle">Q3DockWindow::windowTitle</a>() or <a href="q3toolbar.html#label-prop">Q3ToolBar::label</a>()), so if you enable the <tt>Minimized</tt> dock area, it is best to specify a meaningful caption or label for each dock window. To minimize a dock window programmatically use <a href="q3mainwindow.html#moveDockWindow">moveDockWindow</a>() with an edge of <tt>Minimized</tt>.</p>
<p><a href="qt-qt3.html#Dock-enum">Qt::Dock</a> windows are moved transparently by default, i.e. during the drag an outline rectangle is drawn on the screen representing the position of the dock window as it moves. If you want the dock window to be shown normally whilst it is moved use <a href="q3mainwindow.html#opaqueMoving-prop">setOpaqueMoving</a>().</p>
<p>The location of a dock window, i.e. its dock area and position within the dock area, can be determined by calling <a href="q3mainwindow.html#getLocation">getLocation</a>(). Movable dock windows can be lined up to minimize wasted space with <a href="q3mainwindow.html#lineUpDockWindows">lineUpDockWindows</a>(). Pointers to the dock areas are available from <a href="q3mainwindow.html#topDock">topDock</a>(), <a href="q3mainwindow.html#leftDock">leftDock</a>(), <a href="q3mainwindow.html#rightDock">rightDock</a>() and <a href="q3mainwindow.html#bottomDock">bottomDock</a>(). A customize menu item is added to the pop up dock window menu if <a href="q3mainwindow.html#isCustomizable">isCustomizable</a>() returns true; it returns false by default. Reimplement <a href="q3mainwindow.html#isCustomizable">isCustomizable</a>() and <a href="q3mainwindow.html#customize">customize</a>() if you want to offer this extra menu item, for example, to allow the user to change settings relating to the main window and its toolbars and dock windows.</p>
<p>The main window's menu bar is fixed (at the top) by default. If you want a movable menu bar, create a <a href="qmenubar.html">QMenuBar</a> as a stretchable widget inside its own movable dock window and restrict this dock window to only live within the <tt>Top</tt> or <tt>Bottom</tt> dock:</p>

<a href="q3mainwindow.html#setDockEnabled">setDockEnabled</a>(tb<span class="operator">,</span> Right<span class="operator">,</span> <span class="keyword">false</span>);</pre>
<p>An application with multiple dock windows can choose to save the current dock window layout in order to restore it later, e.g. in the next session. You can do this by using the streaming operators for Q3MainWindow.</p>
<p>To save the layout and positions of all the dock windows do this:</p>
<pre class="cpp"> <span class="type"><a href="qfile.html">QFile</a></span> file(filename);
<span class="keyword">if</span> (file<span class="operator">.</span>open(IO_WriteOnly)) {
<span class="type"><a href="qtextstream.html">QTextStream</a></span> stream(<span class="operator">&</span>file);
stream <span class="operator"><</span><span class="operator"><</span> <span class="operator">*</span>mainWindow;
file<span class="operator">.</span>close();
}</pre>
<p>To restore the dock window positions and sizes (normally when the application is next started), do the following:</p>
<pre class="cpp"> <span class="type"><a href="qfile.html">QFile</a></span> file(filename);
<span class="keyword">if</span> (file<span class="operator">.</span>open(IO_ReadOnly)) {
<span class="type"><a href="qtextstream.html">QTextStream</a></span> stream(<span class="operator">&</span>file);
stream <span class="operator">></span><span class="operator">></span> <span class="operator">*</span>mainWindow;
file<span class="operator">.</span>close();
}</pre>
<p>The <a href="qsettings.html">QSettings</a> class can be used in conjunction with the streaming operators to store the application's settings.</p>
<p>Q3MainWindow's management of dock windows and toolbars is done transparently behind-the-scenes by <a href="q3dockarea.html">Q3DockArea</a>.</p>
<p>For multi-document interfaces (MDI), use a <a href="qworkspace.html" class="obsolete">QWorkspace</a> as the central widget.</p>
<p>Adding dock windows, e.g. toolbars, to Q3MainWindow's dock areas is straightforward. If the supplied dock areas are not sufficient for your application we suggest that you create a <a href="qwidget.html">QWidget</a> subclass and add your own dock areas (see <a href="q3dockarea.html">Q3DockArea</a>) to the subclass since Q3MainWindow provides functionality specific to the standard dock areas it provides.</p>

<p>If <i>b</i> is true, then right clicking on a dock window or dock area will pop up the dock window menu. If <i>b</i> is false, right clicking a dock window or dock area will not pop up the menu.</p>
<p>The menu lists the (<a href="q3mainwindow.html#appropriate">appropriate</a>()) dock windows (which may be shown or hidden), and has a "Line Up Dock Windows" item. It will also have a "Customize" menu item if <a href="q3mainwindow.html#isCustomizable">isCustomizable</a>() returns true.</p>

<p>Shows the dock menu at the position <i>globalPos</i>. The menu lists the dock windows so that they can be shown (or hidden), lined up, and possibly customized. Returns true if the menu is shown; otherwise returns false.</p>
<p>If you want a custom menu, reimplement this function. You can create the menu from scratch or call <a href="q3mainwindow.html#createDockWindowMenu">createDockWindowMenu</a>() and modify the result.</p>
<p>The default implementation uses the dock window menu which gets created by <a href="q3mainwindow.html#createDockWindowMenu">createDockWindowMenu</a>().
