\class TQDockWindow ntqdockwindow.h
\brief The TQDockWindow class provides a widget which can be docked
inside a TQDockArea or floated as a top level window on the
desktop.
\ingroup application
\mainclass
This class handles moving, resizing, docking and undocking dock
windows. 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 ntqdockarea.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.

\fn void TQDockWindow::visibilityChanged( bool visible )
This signal is emitted when the visibility of the dock window

TQDockWindow is now visible to the dock area, otherwise it has been
hidden.
A dock window can be hidden if it has a close button which the

have its visibility changed (hidden or shown) by clicking its name
in the dock window menu that lists the TQMainWindow's dock windows.
