+/*!
+ \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().

+/*!
+ \class KDGanttViewItem KDGanttViewItem.h
+ This class represents an item in a Gantt chart.
+
+ This class is an abstract base class, it cannot be instantiated
+ directly. Instead, you should create items of one of the
+ subclasses. This class provides methods common to all Gantt items.
+
+ The initialization of the shapes/colors of the item works as follows:
+
+ Shapes:
+ When a new item is created, the shapes are set to the default values
+ for items of the type of this item, defined in the KDGanttView class with
+ void setShapes( KDGanttViewItem::Type type,
+ KDGanttViewItem::Shape start,
+ KDGanttViewItem::Shape middle,
+ KDGanttViewItem::Shape end );
+ If there is no default value defined for this type,
+ the shapes are set as follows:
+ For TaskViewItems all three shapes are set to Square.
+ For SummaryViewItems all three shapes are set to TriangleDown.
+ For EventViewItems all three shapes are set to Diamond.
+
+ Colors:
+ When a new item is created, the colors are set to the default values
+ for items of the type of this item, defined in the KDGanttView class with
+ void setColors( KDGanttViewItem::Type type,
+ const QColor& start,
+ const QColor& middle,
+ const QColor& end );
+ If there is no default value defined for this type,
+ the colors of the shapes are set to the default color for items of this type,
+ defined in the KDGanttView class with:
+ void setDefaultColor( KDGanttViewItem::Type type, const QColor& );
+ The initial default color in the KDGanttView class is set to
+ blue for KDGanttViewItem::Event,
+ green for KDGanttViewItem::Task,
+ cyan for KDGanttViewItem::Summary.
+
+ Highlight Colors:
+ When a new item is created, the highlight colors are set to the default
+ values for items of the type of this item,
+ defined in the KDGanttView class with:
+ void setHighlightColors( KDGanttViewItem::Type type,
+ const QColor& start,
+ const QColor& middle,
+ const QColor& end );
+ If there is no default value defined for this type,
+ the highlight colors of the shapes are set to the default color for
+ items of this type, defined in the KDGanttView class with:
+ void setDefaultHighlightColor( KDGanttViewItem::Type type, const QColor& );
+ The initial default highlight color in the KDGanttView class is set to red
+ for all types.
+
+ Start/End time:
+ When a new item is created, the start time and the end time is set
+ automatically. The time, which is currently displayed in the middle
+ of the Gantt View, is set as start/end time. At startup of a newly
+ created Gantt view, this is the current time.
+
+ The Priority:
+ The priority is set with \a setPriority().
+ The priority determines which items are painted over which other items.
+ The item with the highest priority is painted on top of all others.
+ The priority for an item can be between 1 and 199.
+ A priority less than 100 means that the item is painted below the
+ grid in the Gantt chart.
+ For Task items, the default priority is 50, for all other items it is 150.
+ This feature only makes sense for an item which is a child of another item,
+ for which \a displaySubitemsAsGroup() property is set to true.
+
+ The Display Mode:
+ The display mode is set with \a setDisplaySubitemsAsGroup().
+ In the normal view mode (set with setDisplaySubitemsAsGroup( false ); ),
+ an item is displayed in the same manner, when its child items are
+ shown or not.
+ In the other mode (set with setDisplaySubitemsAsGroup( true ); ),
+ called "calendar mode", the item is displayed as follows:
+ If the item has no children, it is displayed as usual.
+ If the item is opened (i.e., its children are displayed), the
+ start/end time of this item is computed automatically according to
+ the earliest start time/latest end time of its children. The item
+ and its children are displayed as usual.
+ If the item is closed (i.e., its children are hidden in the left
+ list view), the item itself is hidden, and its children are displayed
+ on the timeline of this item instead. To control the painting of
+ overlapping children, call \a setPriority() for the childs.
+
+ Blocking of user interaction to open item:
+ If you want to block users to open items used as parents of calendar items,
+ call \a KDGanttView::setCalendarMode( true );
+
+ Example 1, Color:
+ If you create an instance of a KDGanttView class and add a SummaryViewItem
+ without setting any color/shape values, you get an item with three shapes
+ of the form TriangleDown in the color magenta. If the item is highlighted,
+ the color will change to the highlight color red.
+
+ Example 2, Calender View:
+ To use a Gantt view as a calendar view, call
+ \a KDGanttView::setCalendarMode( true );
+ \a KDGanttView::setDisplaySubitemsAsGroup( true );
+ Insert root items in the Gantt view.
+ Insert items as children of these root item in the Gantt view.
+ You may use any item type as parent and child; there are no limitations.
+ It is, however, recommended to use KDGanttViewTaskItems
+ Actually, you may add child items to the children themselves.
+ Such a child behaves then like a parent.
+ Now set the start/end time of the children to specify a time
+ interval for these items.
