Detailed Description

Base class of items in TreeMap.

This class supports an arbitrary number of text() strings positioned counterclock-wise starting at TopLeft. Each item has its own static value(), sum() and sorting(). The splitMode() and borderWidth() is taken from a TreeMapWidget.

If you want more flexibility, reimplement TreeMapItem and override the corresponding methods. For dynamic creation of child items on demand, reimplement children().

enum TreeMapItem::SplitMode

Split direction for nested areas: AlwaysBest: Choose split direction for every subitem according to longest side of rectangle left for drawing Best: Choose split direction for all subitems of an area depending on longest side HAlternate: Horizontal at top; alternate direction on depth step VAlternate: Vertical at top; alternate direction on depth step Horizontal: Always horizontal split direction Vertical: Always vertical split direction.

Member Function Documentation

void TreeMapItem::addFreeRect ( const QRect & r )

Definition at line 1108 of file treemap.cpp.

void TreeMapItem::addItem ( TreeMapItem * i )

Adds an item to a parent.

When no sorting is used, the item is appended (drawn at bottom). This is only needed if the parent was not already specified in the construction of the item.

Definition at line 982 of file treemap.cpp.

int TreeMapItem::borderWidth ( ) const

virtual

Reimplemented in CallMapCallerItem, CallMapCallingItem, PartItem, and BasePartItem.

Definition at line 1031 of file treemap.cpp.

TreeMapItemList * TreeMapItem::children ( )

virtual

Reimplemented in CallMapCallerItem, SubPartItem, CallMapCallingItem, PartItem, CallMapBaseItem, and BasePartItem.

Definition at line 1089 of file treemap.cpp.

void TreeMapItem::clear ( )

Definition at line 927 of file treemap.cpp.

void TreeMapItem::clearFreeRects ( )

Temporary rectangle list of free space of this item.

Used internally to enable tooltip.

Definition at line 1103 of file treemap.cpp.

void TreeMapItem::clearItemRect ( )

Definition at line 1097 of file treemap.cpp.

TreeMapItem * TreeMapItem::commonParent ( TreeMapItem * item )

Definition at line 913 of file treemap.cpp.

int TreeMapItem::depth ( ) const

Depth of this item.

This is the distance to root.

Definition at line 963 of file treemap.cpp.

const QFont & TreeMapItem::font ( ) const

virtual

Reimplemented from StoredDrawParams.

Definition at line 1019 of file treemap.cpp.

const QList<QRect>& TreeMapItem::freeRects ( ) const

inline

Definition at line 303 of file treemap.h.

int TreeMapItem::height ( ) const

inline

Definition at line 296 of file treemap.h.

int TreeMapItem::index ( ) const

inline

Temporary child item index of the child that was current() recently.

Definition at line 309 of file treemap.h.

bool TreeMapItem::initialized ( )

Definition at line 973 of file treemap.cpp.

bool TreeMapItem::isChildOf ( TreeMapItem * item )

Definition at line 901 of file treemap.cpp.

bool TreeMapItem::isMarked ( int ) const

virtual

Reimplemented in CallMapCallerItem, CallMapCallingItem, and CallMapBaseItem.

Definition at line 1025 of file treemap.cpp.

const QRect& TreeMapItem::itemRect ( ) const

inline

Definition at line 294 of file treemap.h.

TreeMapItem* TreeMapItem::parent ( ) const

inline

Parent Item.

Definition at line 286 of file treemap.h.

QStringList TreeMapItem::path ( int textNo ) const

Returns a list of text strings of specified text number, from root up to this item.

Definition at line 949 of file treemap.cpp.

DrawParams::Position TreeMapItem::position ( int f ) const

virtual

Reimplemented from StoredDrawParams.

Definition at line 1009 of file treemap.cpp.

void TreeMapItem::redraw ( )

Definition at line 921 of file treemap.cpp.

void TreeMapItem::refresh ( )

Definition at line 942 of file treemap.cpp.

void TreeMapItem::resort ( bool recursive = true )

Resort according to the already set sorting.

This has to be done if the sorting base changes (e.g. text or values change). If this is only true for the children of this item, you can set the recursive parameter to false.

Definition at line 1063 of file treemap.cpp.

int TreeMapItem::rtti ( ) const

virtual

Reimplemented in CallMapCallerItem, SubPartItem, CallMapCallingItem, PartItem, CallMapBaseItem, and BasePartItem.

Definition at line 1084 of file treemap.cpp.

void TreeMapItem::setIndex ( int i )

inline

Definition at line 310 of file treemap.h.

void TreeMapItem::setItemRect ( const QRect & r )

inline

Temporary rectangle used for drawing this item the last time.

This is internally used to map from a point to an item.

Definition at line 292 of file treemap.h.

void TreeMapItem::setParent ( TreeMapItem * p )

Definition at line 895 of file treemap.cpp.

void TreeMapItem::setSorting	(	int	textNo,
		bool	ascending = `true`
	)

Set the sorting for child drawing.

Default is no sorting: <textNo> = -1 For value() sorting, use <textNo> = -2

For fast sorting, set this to -1 before child insertions and call again after inserting all children.

Definition at line 1046 of file treemap.cpp.

void TreeMapItem::setSum ( double s )

inline

Definition at line 320 of file treemap.h.

void TreeMapItem::setValue ( double s )

Definition at line 321 of file treemap.h.

void TreeMapItem::setWidget ( TreeMapWidget * w )

inline

Definition at line 319 of file treemap.h.

int TreeMapItem::sorting ( bool * ascending ) const

virtual

Returns the text number after that sorting is done or -1 for no sorting, -2 for value() sorting (default).

If ascending != 0, a bool value is written at that location to indicate if sorting should be ascending.

Definition at line 1039 of file treemap.cpp.

TreeMapItem::SplitMode TreeMapItem::splitMode ( ) const
