\class KDGanttMinimizeSplitter KDGanttMinimizeSplitter.h
\brief The KDGanttMinimizeSplitter class implements a splitter
widget with minimize buttons.
This class (and its documentation) is largely a copy of Qt's
QSplitter; the copying was necessary because QSplitter is not
extensible at all. QSplitter and its documentation are licensed
according to the GPL and the Qt Professional License (if you hold
such a license) and are (C) Trolltech AS.
A splitter lets the user control the size of child widgets by
dragging the boundary between the children. Any number of widgets
may be controlled.
To show a QListBox, a QListView and a QTextEdit side by side:
\code
KDGanttMinimizeSplitter *split = new KDGanttMinimizeSplitter( parent );
QListBox *lb = new QListBox( split );
QListView *lv = new QListView( split );
QTextEdit *ed = new QTextEdit( split );
\endcode
In KDGanttMinimizeSplitter, the boundary can be either horizontal or
vertical. The default is horizontal (the children are side by side)
but you can use setOrientation( QSplitter::Vertical ) to set it to
vertical.
Use setResizeMode() to specify
that a widget should keep its size when the splitter is resized.
Although KDGanttMinimizeSplitter normally resizes the children only
at the end of a resize operation, if you call setOpaqueResize( TRUE
) the widgets are resized as often as possible.
The initial distribution of size between the widgets is determined
by the initial size of each widget. You can also use setSizes() to
set the sizes of all the widgets. The function sizes() returns the
sizes set by the user.
If you hide() a child, its space will be distributed among the other
children. It will be reinstated when you show() it again. It is also
possible to reorder the widgets within the splitter using
moveToFirst() and moveToLast().
