|

| 134 |
|
|---|
| 135 | The QMainWindow class provides a main application window,
|
|---|
| 136 | with a menu bar, dock windows (e.g. for toolbars), and a status
|
|---|
| 137 | bar.
|
|---|
| 138 | <p>
|
|---|
| 139 |
|
|---|
| 140 | <p> Main windows are most often used to provide menus, toolbars and a
|
|---|
| 141 | status bar around a large central widget, such as a text edit,
|
|---|
| 142 | drawing canvas or <a href="qworkspace.html">QWorkspace</a> (for MDI applications). QMainWindow
|
|---|
| 143 | is usually subclassed since this makes it easier to encapsulate
|
|---|
| 144 | the central widget, menus and toolbars as well as the window's
|
|---|
| 145 | state. Subclassing makes it possible to create the slots that are
|
|---|
| 146 | called when the user clicks menu items or toolbar buttons. You can
|
|---|
| 147 | also create main windows using <a href="designer-manual.html">Qt
|
|---|
| 148 | Designer</a>. We'll briefly review adding menu items and
|
|---|
| 149 | toolbar buttons then describe the facilities of QMainWindow
|
|---|
| 150 | itself.
|
|---|
| 151 | <p> <pre>
|
|---|
| 152 | QMainWindow *mw = new QMainWindow;
|
|---|
| 153 | <a href="qtextedit.html">QTextEdit</a> *edit = new <a href="qtextedit.html">QTextEdit</a>( mw, "editor" );
|
|---|
| 154 | edit-><a href="qwidget.html#setFocus">setFocus</a>();
|
|---|
| 155 | mw-><a href="qwidget.html#setCaption">setCaption</a>( "Main Window" );
|
|---|
| 156 | mw-><a href="#setCentralWidget">setCentralWidget</a>( edit );
|
|---|
| 157 | mw-><a href="qwidget.html#show">show</a>();
|
|---|
| 158 | </pre>
|
|---|
| 159 |
|
|---|
| 160 | <p> QMainWindows may be created in their own right as shown above.
|
|---|
| 161 | The central widget is set with <a href="#setCentralWidget">setCentralWidget</a>(). Popup menus can
|
|---|
| 162 | be added to the default menu bar, widgets can be added to the
|
|---|
| 163 | status bar, toolbars and dock windows can be added to any of the
|
|---|
| 164 | dock areas.
|
|---|
| 165 | <p>
|
|---|
| 166 |
|
|---|
| 167 | <pre> ApplicationWindow *mw = new ApplicationWindow();
|
|---|
| 168 | mw-><a href="qwidget.html#setCaption">setCaption</a>( "Qt Example - Application" );
|
|---|
| 169 | <a name="x2115"></a> mw-><a href="qwidget.html#show">show</a>();
|
|---|
| 170 | </pre>
|
|---|
| 171 | <p> In the extract above ApplicationWindow is a subclass of
|
|---|
| 172 | QMainWindow that we must write for ourselves; this is the usual
|
|---|
| 173 | approach to using QMainWindow. (The source for the extracts in
|
|---|
| 174 | this description are taken from <a href="simple-application-example.html">application/main.cpp</a>, <a href="simple-application-example.html">application/application.cpp</a>, <a href="qaction-application-example.html">action/main.cpp</a>, and <a href="qaction-application-example.html">action/application.cpp</a> )
|
|---|
| 175 | <p> When subclassing we add the menu items and toolbars in the
|
|---|
| 176 | subclass's constructor. If we've created a QMainWindow instance
|
|---|
| 177 | directly we can add menu items and toolbars just as easily by
|
|---|
| 178 | passing the QMainWindow instance as the parent instead of the <em>this</em> pointer.
|
|---|
| 179 | <p>
|
|---|
| 180 |
|
|---|
| 181 | <pre> <a href="qpopupmenu.html">QPopupMenu</a> * help = new <a href="qpopupmenu.html">QPopupMenu</a>( this );
|
|---|
| 182 | <a href="#menuBar">menuBar</a>()->insertItem( "&Help", help );
|
|---|
| 183 |
|
|---|
| 184 | help-><a href="qmenudata.html#insertItem">insertItem</a>( "&About", this, SLOT(about()), Key_F1 );
|
|---|
| 185 | </pre>
|
|---|
| 186 | <p> Here we've added a new menu with one menu item. The menu has been
|
|---|
| 187 | inserted into the menu bar that QMainWindow provides by default
|
|---|
| 188 | and which is accessible through the <a href="#menuBar">menuBar</a>() function. The slot
|
|---|
| 189 | will be called when the menu item is clicked.
|
|---|
| 190 | <p>
|
|---|
| 191 |
|
|---|
| 192 | <pre> <a href="qtoolbar.html">QToolBar</a> * fileTools = new <a href="qtoolbar.html">QToolBar</a>( this, "file operations" );
|
|---|
| 193 | fileTools-><a href="qtoolbar.html#setLabel">setLabel</a>( "File Operations" );
|
|---|
| 194 | </pre><pre> QToolButton * fileOpen
|
|---|
| 195 | = new <a href="qtoolbutton.html">QToolButton</a>( openIcon, "Open File", <a href="qstring.html#QString-null">QString::null</a>,
|
|---|
| 196 | this, SLOT(choose()), fileTools, "open file" );
|
|---|
| 197 | </pre>
|
|---|
| 198 | <p> This extract shows the creation of a toolbar with one toolbar
|
|---|
| 199 | button. QMainWindow supplies four dock areas for toolbars. When a
|
|---|
| 200 | toolbar is created as a child of a QMainWindow (or derived class)
|
|---|
| 201 | instance it will be placed in a dock area (the <a href="qt.html#Dock-enum">Top</a> dock area by
|
|---|
| 202 | default). The slot will be called when the toolbar button is
|
|---|
| 203 | clicked. Any dock window can be added to a dock area either using
|
|---|
| 204 | <a href="#addDockWindow">addDockWindow</a>(), or by creating a dock window with the QMainWindow
|
|---|
| 205 | as the parent.
|
|---|
| 206 | <p>
|
|---|
| 207 |
|
|---|
| 208 | <pre> e = new <a href="qtextedit.html">QTextEdit</a>( this, "editor" );
|
|---|
| 209 | e-><a href="qwidget.html#setFocus">setFocus</a>();
|
|---|
| 210 | <a href="#setCentralWidget">setCentralWidget</a>( e );
|
|---|
| 211 | <a href="#statusBar">statusBar</a>()->message( "Ready", 2000 );
|
|---|
| 212 | </pre>
|
|---|
| 213 | <p> Having created the menus and toolbar we create an instance of the
|
|---|
| 214 | large central widget, give it the focus and set it as the main
|
|---|
| 215 | window's central widget. In the example we've also set the status
|
|---|
| 216 | bar, accessed via the <a href="#statusBar">statusBar</a>() function, to an initial message
|
|---|
| 217 | which will be displayed for two seconds. Note that you can add
|
|---|
| 218 | additional widgets to the status bar, for example labels, to show
|
|---|
| 219 | further status information. See the <a href="qstatusbar.html">QStatusBar</a> documentation for
|
|---|
| 220 | details, particularly the addWidget() function.
|
|---|
| 221 | <p> Often we want to synchronize a toolbar button with a menu item.
|
|---|
| 222 | For example, if the user clicks a 'bold' toolbar button we want
|
|---|
| 223 | the 'bold' menu item to be checked. This synchronization can be
|
|---|
| 224 | achieved automatically by creating actions and adding the actions
|
|---|
| 225 | to the toolbar and menu.
|
|---|
| 226 | <p>
|
|---|
| 227 |
|
|---|
| 228 | <pre> <a href="qaction.html">QAction</a> * fileOpenAction;
|
|---|
| 229 | </pre><pre> fileOpenAction = new <a href="qaction.html">QAction</a>( QPixmap( fileopen ), "&Open...",
|

| 230 | CTRL+Key_O, this, "open" );

| 231 | <a href="qobject.html#connect">connect</a>( fileOpenAction, SIGNAL( <a href="qaction.html#activated">activated</a>() ) , this, SLOT( choose() ) );
|
|---|
| 232 | </pre>
|
|---|
| 233 | <p> Here we create an action with an icon which will be used in any
|
|---|
| 234 | menu and toolbar that the action is added to. We've also given the
|
|---|
| 235 | action a menu name, '&Open', and a keyboard shortcut. The
|
|---|
| 236 | connection that we have made will be used when the user clicks
|
|---|
| 237 | either the menu item <em>or</em> the toolbar button.
|
|---|
| 238 | <p>
|
|---|
| 239 |
|
|---|
| 240 | <pre> <a href="qpopupmenu.html">QPopupMenu</a> * file = new <a href="qpopupmenu.html">QPopupMenu</a>( this );

|
|---|
| 243 | </pre>
|
|---|
| 244 | <p> The extract above shows the creation of a popup menu. We add the
|
|---|
| 245 | menu to the QMainWindow's menu bar and add our action.

| 251 | </pre>
|
|---|
| 252 | <p> Here we create a new toolbar as a child of the QMainWindow and add
|
|---|
| 253 | our action to the toolbar.
|
|---|
| 254 | <p> We'll now explore the functionality offered by QMainWindow.
|
|---|
| 255 | <p> The main window will take care of the dock areas, and the geometry
|
|---|
| 256 | of the central widget, but all other aspects of the central widget
|
|---|
| 257 | are left to you. QMainWindow automatically detects the creation of
|
|---|
| 258 | a menu bar or status bar if you specify the QMainWindow as parent,
|
|---|
| 259 | or you can use the provided <a href="#menuBar">menuBar</a>() and <a href="#statusBar">statusBar</a>() functions.
|
|---|
| 260 | The functions menuBar() and statusBar() create a suitable widget
|
|---|
| 261 | if one doesn't exist, and update the window's layout to make
|
|---|
| 262 | space.
|
|---|
| 263 | <p> QMainWindow provides a <a href="qtooltipgroup.html">QToolTipGroup</a> connected to the status bar.
|
|---|
| 264 | The function <a href="#toolTipGroup">toolTipGroup</a>() provides access to the default
|
|---|
| 265 | QToolTipGroup. It isn't possible to set a different tool tip
|
|---|
| 266 | group.
|
|---|
| 267 | <p> New dock windows and toolbars can be added to a QMainWindow using
|
|---|
| 268 | <a href="#addDockWindow">addDockWindow</a>(). Dock windows can be moved using <a href="#moveDockWindow">moveDockWindow</a>()
|
|---|
| 269 | and removed with <a href="#removeDockWindow">removeDockWindow</a>(). QMainWindow allows default
|
|---|
| 270 | dock window (toolbar) docking in all its dock areas (<a href="qt.html#Dock-enum">Top</a>, <a href="qt.html#Dock-enum">Left</a>, <a href="qt.html#Dock-enum">Right</a>, <a href="qt.html#Dock-enum">Bottom</a>). You can use <a href="#setDockEnabled">setDockEnabled</a>() to
|
|---|
| 271 | enable and disable docking areas for dock windows. When adding or
|
|---|
| 272 | moving dock windows you can specify their 'edge' (dock area). The
|
|---|
| 273 | currently available edges are: <a href="qt.html#Dock-enum">Top</a>, <a href="qt.html#Dock-enum">Left</a>, <a href="qt.html#Dock-enum">Right</a>, <a href="qt.html#Dock-enum">Bottom</a>, <a href="qt.html#Dock-enum">Minimized</a> (effectively a 'hidden' dock area) and <a href="qt.html#Dock-enum">TornOff</a> (floating). See <a href="qt.html#Dock-enum">Qt::Dock</a> for an explanation of these
|
|---|
| 274 | areas. Note that the *ToolBar functions are included for backward
|
|---|
| 275 | compatibility; all new code should use the *DockWindow functions.
|
|---|
| 276 | QToolbar is a subclass of <a href="qdockwindow.html">QDockWindow</a> so all functions that work
|
|---|
| 277 | with dock windows work on toolbars in the same way.
|
|---|
| 278 | <p> <a name="dwm"></a>
|
|---|
| 279 | If the user clicks the close button, then the dock window is
|
|---|
| 280 | hidden. A dock window can be hidden or unhidden by the user by
|
|---|
| 281 | right clicking a dock area and clicking the name of the relevant
|
|---|
| 282 | dock window on the pop up dock window menu. This menu lists the
|
|---|
| 283 | names of every dock window; visible dock windows have a tick
|
|---|
| 284 | beside their names. The dock window menu is created automatically
|
|---|
| 285 | as required by <a href="#createDockWindowMenu">createDockWindowMenu</a>(). Since it may not always be
|
|---|
| 286 | appropriate for a dock window to appear on this menu the
|
|---|
| 287 | <a href="#setAppropriate">setAppropriate</a>() function is used to inform the main window
|
|---|
| 288 | whether or not the dock window menu should include a particular
|
|---|
| 289 | dock window. Double clicking a dock window handle (usually on the
|
|---|
| 290 | left-hand side of the dock window) undocks (floats) the dock
|
|---|
| 291 | window. Double clicking a floating dock window's titlebar will
|
|---|
| 292 | dock the floating dock window. (See also
|
|---|
| 293 | <a href="#DockWindows-enum">QMainWindow::DockWindows</a>.)
|
|---|
| 294 | <p> Some functions change the appearance of a QMainWindow globally:
|
|---|
| 295 | <ul>
|
|---|
| 296 | <li> <a href="qdockwindow.html#setHorizontalStretchable">QDockWindow::setHorizontalStretchable</a>() and
|
|---|
| 297 | <a href="qdockwindow.html#setVerticalStretchable">QDockWindow::setVerticalStretchable</a>() are used to make specific dock
|
|---|
| 298 | windows or toolbars stretchable.
|
|---|
| 299 | <li> <a href="#setUsesBigPixmaps">setUsesBigPixmaps</a>() is used to set whether tool buttons should
|
|---|
| 300 | draw small or large pixmaps (see <a href="qiconset.html">QIconSet</a> for more information).
|
|---|
| 301 | <li> <a href="#setUsesTextLabel">setUsesTextLabel</a>() is used to set whether tool buttons
|
|---|
| 302 | should display a textual label in addition to pixmaps
|
|---|
| 303 | (see <a href="qtoolbutton.html">QToolButton</a> for more information).
|
|---|
| 304 | </ul>
|
|---|
| 305 | <p> The user can drag dock windows into any enabled docking area. Dock
|
|---|
| 306 | windows can also be dragged <em>within</em> a docking area, for example
|
|---|
| 307 | to rearrange the order of some toolbars. Dock windows can also be
|
|---|
| 308 | dragged outside any docking area (undocked or 'floated'). Being
|
|---|
| 309 | able to drag dock windows can be enabled (the default) and
|
|---|
| 310 | disabled using <a href="#setDockWindowsMovable">setDockWindowsMovable</a>().
|
|---|
| 311 | <p> The <a href="qt.html#Dock-enum">Minimized</a> edge is a hidden dock area. If this dock area is
|
|---|
| 312 | enabled the user can hide (minimize) a dock window or show (restore)
|
|---|
| 313 | a minimized dock window by clicking the dock window handle. If the
|
|---|
| 314 | user hovers the mouse cursor over one of the handles, the caption of
|
|---|
| 315 | the dock window is displayed in a tool tip (see
|
|---|
| 316 | <a href="qwidget.html#caption">QDockWindow::caption</a>() or <a href="qtoolbar.html#label">QToolBar::label</a>()), so if you enable the
|
|---|
| 317 | <a href="qt.html#Dock-enum">Minimized</a> dock area, it is best to specify a meaningful caption
|
|---|
| 318 | or label for each dock window. To minimize a dock window
|
|---|
| 319 | programmatically use <a href="#moveDockWindow">moveDockWindow</a>() with an edge of <a href="qt.html#Dock-enum">Minimized</a>.
|
|---|
| 320 | <p> Dock windows are moved transparently by default, i.e. during the
|
|---|
| 321 | drag an outline rectangle is drawn on the screen representing the
|
|---|
| 322 | position of the dock window as it moves. If you want the dock
|
|---|
| 323 | window to be shown normally whilst it is moved use
|
|---|
| 324 | <a href="#setOpaqueMoving">setOpaqueMoving</a>().
|
|---|
| 325 | <p> The location of a dock window, i.e. its dock area and position
|
|---|
| 326 | within the dock area, can be determined by calling <a href="#getLocation">getLocation</a>().
|
|---|
| 327 | Movable dock windows can be lined up to minimize wasted space with
|
|---|
| 328 | <a href="#lineUpDockWindows">lineUpDockWindows</a>(). Pointers to the dock areas are available from
|
|---|
| 329 | <a href="#topDock">topDock</a>(), <a href="#leftDock">leftDock</a>(), <a href="#rightDock">rightDock</a>() and <a href="#bottomDock">bottomDock</a>(). A customize
|
|---|
| 330 | menu item is added to the pop up dock window menu if
|
|---|
| 331 | <a href="#isCustomizable">isCustomizable</a>() returns TRUE; it returns FALSE by default.
|
|---|
| 332 | Reimplement isCustomizable() and <a href="#customize">customize</a>() if you want to offer
|
|---|
| 333 | this extra menu item, for example, to allow the user to change
|
|---|
| 334 | settings relating to the main window and its toolbars and dock
|
|---|
| 335 | windows.
|
|---|
| 336 | <p> The main window's menu bar is fixed (at the top) by default. If
|
|---|
| 337 | you want a movable menu bar, create a <a href="qmenubar.html">QMenuBar</a> as a stretchable
|
|---|
| 338 | widget inside its own movable dock window and restrict this dock
|
|---|
| 339 | window to only live within the <a href="qt.html#Dock-enum">Top</a> or <a href="qt.html#Dock-enum">Bottom</a> dock:
|
|---|
| 340 | <p> <pre>
|
|---|
| 341 | <a href="qtoolbar.html">QToolBar</a> *tb = new <a href="qtoolbar.html">QToolBar</a>( this );
|
|---|
| 342 | <a href="#addDockWindow">addDockWindow</a>( tb, tr( "Menubar" ), Top, FALSE );
|
|---|
| 343 | <a href="qmenubar.html">QMenuBar</a> *mb = new <a href="qmenubar.html">QMenuBar</a>( tb );
|
|---|
| 344 | mb-><a href="qframe.html#setFrameStyle">setFrameStyle</a>( QFrame::NoFrame );
|
|---|
| 345 | tb-><a href="qtoolbar.html#setStretchableWidget">setStretchableWidget</a>( mb );
|
|---|
| 346 | <a href="#setDockEnabled">setDockEnabled</a>( tb, Left, FALSE );
|
|---|
| 347 | <a href="#setDockEnabled">setDockEnabled</a>( tb, Right, FALSE );
|
|---|
| 348 | </pre>
|
|---|
| 349 |
|
|---|
| 350 | <p> An application with multiple dock windows can choose to save the
|
|---|
| 351 | current dock window layout in order to restore it later, e.g. in
|
|---|
| 352 | the next session. You can do this by using the streaming operators
|
|---|
| 353 | for QMainWindow.
|
|---|
| 354 | <p> To save the layout and positions of all the dock windows do this:
|
|---|
| 355 | <p> <pre>
|
|---|
| 356 | <a href="qfile.html">QFile</a> file( filename );
|
|---|
| 357 | if ( file.<a href="qfile.html#open">open</a>( <a href="qfile.html#open">IO_WriteOnly</a> ) ) {
|
|---|
| 358 | <a href="qtextstream.html">QTextStream</a> stream( &file );
|
|---|
| 359 | stream << *mainWindow;
|
|---|
| 360 | file.<a href="qfile.html#close">close</a>();
|
|---|
| 361 | }
|
|---|
| 362 | </pre>
|
|---|
| 363 |
|
|---|
| 364 | <p> To restore the dock window positions and sizes (normally when the
|
|---|
| 365 | application is next started), do following:
|
|---|
| 366 | <p> <pre>
|
|---|
| 367 | <a href="qfile.html">QFile</a> file( filename );
|
|---|
| 368 | if ( file.<a href="qfile.html#open">open</a>( <a href="qfile.html#open">IO_ReadOnly</a> ) ) {
|
|---|
| 369 | <a href="qtextstream.html">QTextStream</a> stream( &file );
|
|---|
| 370 | stream >> *mainWindow;
|
|---|
| 371 | file.<a href="qfile.html#close">close</a>();
|
|---|
| 372 | }
|
|---|
| 373 | </pre>
|
|---|
| 374 |
|
|---|
| 375 | <p> The <a href="qsettings.html">QSettings</a> class can be used in conjunction with the streaming
|
|---|
| 376 | operators to store the application's settings.
|
|---|
| 377 | <p> QMainWindow's management of dock windows and toolbars is done
|
|---|
| 378 | transparently behind-the-scenes by <a href="qdockarea.html">QDockArea</a>.
|
|---|
| 379 | <p> For multi-document interfaces (MDI), use a <a href="qworkspace.html">QWorkspace</a> as the
|
|---|
| 380 | central widget.
|
|---|
| 381 | <p> Adding dock windows, e.g. toolbars, to QMainWindow's dock areas is
|
|---|
| 382 | straightforward. If the supplied dock areas are not sufficient for
|
|---|
| 383 | your application we suggest that you create a <a href="qwidget.html">QWidget</a> subclass and
|
|---|
| 384 | add your own dock areas (see <a href="qdockarea.html">QDockArea</a>) to the subclass since
|
|---|
| 385 | QMainWindow provides functionality specific to the standard dock
|
|---|
| 386 | areas it provides.
