TQToolBar is a subclass of TQDockWindow so the + functionality provided for dock windows is available with the same + API for toolbars. + + \img qmainwindow-qdockareas.png TQDockWindows in a TQDockArea + \caption Two TQDockWindows (\l{TQToolBar}s) in a \l TQDockArea + + \img qdockwindow.png A TQDockWindow + \caption A Floating TQDockWindow + + If the user drags the dock window into the dock area the dock + window will be docked. If the user drags the dock area outside any + dock areas the dock window will be undocked (floated) and will + become a top level window. Double clicking a floating dock + window's titlebar will dock the dock window to the last dock area + it was docked in. Double clicking a docked dock window's handle + will undock (float) the dock window. + \omit + Single clicking a docked dock window's handle will minimize the + dock window (only its handle will appear, below the menu bar). + Single clicking the minimized handle will restore the dock window + to the last dock area that it was docked in. + \endomit + If the user clicks the close button (which does not appear on + dock windows by default - see \l closeMode) the dock window will + disappear. You can control whether or not a dock window has a + close button with setCloseMode(). + + TQMainWindow provides four dock areas (top, left, right and bottom) + which can be used by dock windows. For many applications using the + dock areas provided by TQMainWindow is sufficient. (See the \l + TQDockArea documentation if you want to create your own dock + areas.) In TQMainWindow a right-click popup menu (the dock window + menu) is available which lists dock windows and can be used to + show or hide them. (The popup menu only lists dock windows that + have a \link setCaption() caption\endlink.) + + When you construct a dock window you \e must pass it a TQDockArea + or a TQMainWindow as its parent if you want it docked. Pass 0 for + the parent if you want it floated. + + \code + TQToolBar *fileTools = new TQToolBar( this, "File Actions" ); + moveDockWindow( fileTools, Left ); + \endcode + + In the example above we create a new TQToolBar in the constructor + of a TQMainWindow subclass (so that the \e this pointer points to + the TQMainWindow). By default the toolbar will be added to the \c + Top dock area, but we've moved it to the \c Left dock area. + + A dock window is often used to contain a single widget. In these + cases the widget can be set by calling setWidget(). If you're + constructing a dock window that contains multiple widgets, e.g. a + toolbar, arrange the widgets within a box layout inside the dock + window. To do this use the boxLayout() function to get a pointer + to the dock window's box layout, then add widgets to the layout + using the box layout's TQBoxLayout::addWidget() function. The dock + window will dynamically set the orientation of the layout to be + vertical or horizontal as necessary, although you can control this + yourself with setOrientation(). + + Although a common use of dock windows is for toolbars, they can be + used with any widgets. (See the \link designer-manual.book TQt + Designer\endlink and \link linguist-manual.book TQt + Linguist\endlink applications, for example.) When using larger + widgets it may make sense for the dock window to be resizable by + calling setResizeEnabled(). Resizable dock windows are given + splitter-like handles to allow the user to resize them within + their dock area. When resizable dock windows are undocked they + become top level windows and can be resized like any other top + level windows, e.g. by dragging a corner or edge. + + Dock windows can be docked and undocked using dock() and undock(). + A dock window's orientation can be set with setOrientation(). You + can also use TQDockArea::moveDockWindow(). If you're using a + TQMainWindow, TQMainWindow::moveDockWindow() and + TQMainWindow::removeDockWindow() are available. + + A dock window can have some preferred settings, for example, you + can set a preferred offset from the left edge (or top edge for + vertical dock areas) of the dock area using setOffset(). If you'd + prefer a dock window to start on a new \link qdockarea.html#lines + line\endlink when it is docked use setNewLine(). The + setFixedExtentWidth() and setFixedExtentHeight() functions can be + used to define the dock window's preferred size, and the + setHorizontallyStretchable() and setVerticallyStretchable() + functions set whether the dock window can be stretched or not. + Dock windows can be moved by default, but this can be changed with + setMovingEnabled(). When a dock window is moved it is shown as a + rectangular outline, but it can be shown normally using + setOpaqueMoving(). + + When a dock window's visibility changes, i.e. it is shown or + hidden, the visibilityChanged() signal is emitted. When a dock + window is docked, undocked or moved inside the dock area the + placeChanged() signal is emitted. +*/ + +/*! + \enum TQDockWindow::Place + + This enum specifies the possible locations for a TQDockWindow: + + \value InDock Inside a TQDockArea. + \value OutsideDock Floating as a top level window on the desktop. +*/ + +/*! + \enum TQDockWindow::CloseMode + + This enum type specifies when (if ever) a dock window has a close + button. + + \value Never The dock window never has a close button and cannot + be closed by the user. + \value Docked The dock window has a close button only when + docked. + \value Undocked The dock window has a close button only when + floating. + \value Always The dock window always has a close button. + \omit + Note that dock windows can always be minimized if the user clicks + their dock window handle when they are docked. + \endomit +*/ + +/*! + \fn void TQDockWindow::setHorizontalStretchable( bool b ) + \obsolete +*/ +/*! + \fn void TQDockWindow::setVerticalStretchable( bool b ) + \obsolete +*/ +/*! + \fn bool TQDockWindow::isHorizontalStretchable() const + \obsolete +*/ +/*! + \fn bool TQDockWindow::isVerticalStretchable() const + \obsolete +*/ +/*! + \fn void TQDockWindow::orientationChanged( Orientation o ) + + This signal is emitted when the orientation of the dock window is + changed.
