Detailed Description
A dictionary for plot items.
QwtPlotDict organizes plot items in increasing z-order. If autoDelete() is enabled, all attached items will be deleted in the destructor of the dictionary. QwtPlotDict can be used to get access to all QwtPlotItem items - or all items of a specific type - that are currently on the plot.

Constructor & Destructor Documentation
| QwtPlotDict::QwtPlotDict | ( | ) | [explicit] |
Constructor
Auto deletion is enabled.
- See also:
- setAutoDelete(), QwtPlotItem::attach()
Definition at line 68 of file qwt_plot_dict.cpp.
| QwtPlotDict::~QwtPlotDict | ( | ) | [virtual] |
Destructor
If autoDelete() is on, all attached items will be deleted

Member Function Documentation
| bool QwtPlotDict::autoDelete | ( | ) | const |
- Returns:
- true if auto deletion is enabled
- See also:
- setAutoDelete(), insertItem()
Definition at line 103 of file qwt_plot_dict.cpp.
| void QwtPlotDict::detachItems | ( | int | rtti = QwtPlotItem::Rtti_PlotItem, |
| bool | autoDelete = true |
||
| ) |
Detach items from the dictionary
- Parameters:
-
rtti In case of QwtPlotItem::Rtti_PlotItem detach all items otherwise only those items of the type rtti. autoDelete If true, delete all detached items
Definition at line 137 of file qwt_plot_dict.cpp.
| void QwtPlotDict::insertItem | ( | QwtPlotItem * | item | ) | [protected] |
Insert a plot item
- Parameters:
-
item PlotItem
- See also:
- removeItem()
Definition at line 114 of file qwt_plot_dict.cpp.
| const QwtPlotItemList & QwtPlotDict::itemList | ( | ) | const |
A QwtPlotItemList of all attached plot items.
Use caution when iterating these lists, as removing/detaching an item will invalidate the iterator. Instead you can place pointers to objects to be removed in a removal list, and traverse that list later.
- Returns:
- List of all attached plot items.
Definition at line 165 of file qwt_plot_dict.cpp.
| QwtPlotItemList QwtPlotDict::itemList | ( | int | rtti | ) | const |
- Returns:
- List of all attached plot items of a specific type.
- Parameters:
-
rtti See QwtPlotItem::RttiValues
- See also:
- QwtPlotItem::rtti()
Definition at line 175 of file qwt_plot_dict.cpp.
| void QwtPlotDict::removeItem | ( | QwtPlotItem * | item | ) | [protected] |
Remove a plot item
- Parameters:
-
item PlotItem
- See also:
- insertItem()
Definition at line 125 of file qwt_plot_dict.cpp.
| void QwtPlotDict::setAutoDelete | ( | bool | autoDelete | ) |
En/Disable Auto deletion
If Auto deletion is on all attached plot items will be deleted in the destructor of QwtPlotDict. The default value is on.
