\class Q3DockWindow |
|
747 |
\brief The Q3DockWindow class provides a widget which can be docked |
|
748 |
inside a Q3DockArea or floated as a top level window on the |
|
749 |
desktop. |
|
750 |
||
751 |
\compat |
|
752 |
||
753 |
This class handles moving, resizing, docking and undocking dock |
|
754 |
windows. Q3ToolBar is a subclass of Q3DockWindow so the |
|
755 |
functionality provided for dock windows is available with the same |
|
756 |
API for toolbars. |
|
757 |

\caption A Floating Q3DockWindow |
|

764 |
If the user drags the dock window into the dock area the dock |
|
765 |
window will be docked. If the user drags the dock area outside any |
|
766 |
dock areas the dock window will be undocked (floated) and will |
|
767 |
become a top level window. Double clicking a floating dock |
|
768 |
window's title bar will dock the dock window to the last dock area |
|
769 |
it was docked in. Double clicking a docked dock window's handle |
|
770 |
will undock (float) the dock window. |
|
771 |
\omit |
|
772 |
Single clicking a docked dock window's handle will minimize the |
|
773 |
dock window (only its handle will appear, below the menu bar). |
|
774 |
Single clicking the minimized handle will restore the dock window |
|
775 |
to the last dock area that it was docked in. |
|
776 |
\endomit |
|
777 |
If the user clicks the close button (which appears on floating |
|
778 |
dock windows by default) the dock window will disappear. You can |
|
779 |
control whether or not a dock window has a close button with |
|
780 |
setCloseMode(). |
|
781 |
||
782 |
Q3MainWindow provides four dock areas (top, left, right and bottom) |
|
783 |
which can be used by dock windows. For many applications using the |
|
784 |
dock areas provided by Q3MainWindow is sufficient. (See the \l |
|
785 |
Q3DockArea documentation if you want to create your own dock |
|
786 |
areas.) In Q3MainWindow a right-click popup menu (the dock window |
|
787 |
menu) is available which lists dock windows and can be used to |
|
788 |
show or hide them. (The popup menu only lists dock windows that |
|
789 |
have a \link QWidget::setWindowTitle() caption\endlink.) |

When you construct a dock window you \e must pass it a Q3DockArea |
|
792 |
or a Q3MainWindow as its parent if you want it docked. Pass 0 for |
|
793 |
the parent if you want it floated. |
|
794 |
||
795 |
\snippet doc/src/snippets/code/src_qt3support_widgets_q3dockwindow.cpp 0 |
|
796 |
||
797 |
In the example above we create a new Q3ToolBar in the constructor |
|
798 |
of a Q3MainWindow subclass (so that the \e this pointer points to |
|
799 |
the Q3MainWindow). By default the toolbar will be added to the \c |
|
800 |
Top dock area, but we've moved it to the \c Left dock area. |
|
801 |
||
802 |
A dock window is often used to contain a single widget. In these |
|
803 |
cases the widget can be set by calling setWidget(). If you're |
|
804 |
constructing a dock window that contains multiple widgets, e.g. a |
|
805 |
toolbar, arrange the widgets within a box layout inside the dock |
|
806 |
window. To do this use the boxLayout() function to get a pointer |
|
807 |
to the dock window's box layout, then add widgets to the layout |
|
808 |
using the box layout's QBoxLayout::addWidget() function. The dock |
|
809 |
window will dynamically set the orientation of the layout to be |
|
810 |
vertical or horizontal as necessary, although you can control this |
|
811 |
yourself with setOrientation(). |
|
812 |
||
813 |
Although a common use of dock windows is for toolbars, they can be |
|
814 |
used with any widgets. When using larger |
|
815 |
widgets it may make sense for the dock window to be resizable by |
|
816 |
calling setResizeEnabled(). Resizable dock windows are given |
|
817 |
splitter-like handles to allow the user to resize them within |
|
818 |
their dock area. When resizable dock windows are undocked they |
|
819 |
become top level windows and can be resized like any other top |
|
820 |
level windows, e.g. by dragging a corner or edge. |
|
821 |
||
822 |
Qt::Dock windows can be docked and undocked using dock() and undock(). |
|
823 |
A dock window's orientation can be set with setOrientation(). You |
|
824 |
can also use Q3DockArea::moveDockWindow(). If you're using a |
|
825 |
Q3MainWindow, Q3MainWindow::moveDockWindow() and |
|
826 |
Q3MainWindow::removeDockWindow() are available. |
|
827 |
||
828 |
A dock window can have some preferred settings, for example, you |
|
829 |
can set a preferred offset from the left edge (or top edge for |
|
830 |
vertical dock areas) of the dock area using setOffset(). If you'd |
|
831 |
prefer a dock window to start on a new line when it is docked use |
|
832 |
setNewLine(). The setFixedExtentWidth() and setFixedExtentHeight() |
|
833 |
functions can be used to define the dock window's preferred size, |
|
834 |
and the setHorizontallyStretchable() and setVerticallyStretchable() |
|
835 |
functions set whether the dock window can be stretched or not. |
|
836 |
Dock windows can be moved by default, but this can be changed with |
|
837 |
setMovingEnabled(). When a dock window is moved it is shown as a |
|
838 |
rectangular outline, but it can be shown normally using |
|
839 |
setOpaqueMoving(). |
|
840 |
||
841 |
When a dock window's visibility changes, i.e. it is shown or |
|
842 |
hidden, the visibilityChanged() signal is emitted. When a dock |
|
843 |
window is docked, undocked or moved inside the dock area the |
|
844 |
placeChanged() signal is emitted. |
