\class QDockArea qdockarea.h
|
|
\brief The QDockArea class manages and lays out QDockWindows.
|
|
|
|
\ingroup application
|
|
|
|
A QDockArea is a container which manages a list of
|
|
\l{QDockWindow}s which it lays out within its area. In cooperation
|
|
with the \l{QDockWindow}s it is responsible for the docking and
|
|
undocking of \l{QDockWindow}s and moving them inside the dock
|
|
area. QDockAreas also handle the wrapping of \l{QDockWindow}s to
|
|
fill the available space as compactly as possible. QDockAreas can
|
|
contain QToolBars since QToolBar is a QDockWindow subclass.
|
|
|
|
QMainWindow contains four QDockAreas which you can use for your
|
|
QToolBars and QDockWindows, so in most situations you do not need
|
|
to use the QDockArea class directly. Although QMainWindow contains
|
|
support for its own dock areas it isn't convenient for adding new
|
|
QDockAreas. If you need to create your own dock areas we suggest
|
|
that you create a subclass of QWidget and add your QDockAreas to
|
|
your subclass.
|
|
|
|

|
|
|
|
\target lines
|
|
\e Lines. QDockArea uses the concept of lines. A line is a
|
|
horizontal region which may contain dock windows side-by-side. A
|
|
dock area may have room for more than one line. When dock windows
|
|
are docked into a dock area they are usually added at the right
|
|
hand side of the top-most line that has room (unless manually
|
|
placed by the user). When users move dock windows they may leave
|
|
empty lines or gaps in non-empty lines. Dock windows can be lined
|
|
up to minimize wasted space using the lineUp() function.
|
|
|
|
The QDockArea class maintains a position list of all its child
|
|
dock windows. Dock windows are added to a dock area from position
|
|
0 onwards. Dock windows are laid out sequentially in position
|
|
order from left to right, and in the case of multiple lines of
|
|
dock windows, from top to bottom. If a dock window is floated it
|
|
still retains its position since this is where the window will
|
|
return if the user double clicks its caption. A dock window's
|
|
position can be determined with hasDockWindow(). The position can
|
|
be changed with moveDockWindow().
|
|
|
|
To dock or undock a dock window use QDockWindow::dock() and
|
|

dock windows can dock in a dock area use setAcceptDockWindow(). To

see if a dock area contains a particular dock window use

\l{hasDockWindow()}; to see how many dock windows a dock area

The streaming operators can write the positions of the dock

Save the positions to a QTextStream:

Restore the positions from a QTextStream:
