|
|
* The TDEStyle class extends the TQt's Style API by providing certain
|
|
* simplifications for parts of TQStyle. To do this, the TDEStylePrimitive
|
|
* elements were defined, which are very similar to TQt's PrimitiveElement.
|
|
*
|
|
* The first three Handle primitives simplify and extend PE_DockWindowHandle,
|
|
* so do not reimplement PE_DockWindowHandle if you want the TDEStyle handle
|
|
* simplifications to be operable. Similarly do not reimplement CC_Slider,
|
|
* SC_SliderGroove and SC_SliderHandle when using the TDEStyle slider
|
|
* primitives. TDEStyle automatically double-buffers slider painting
|
|
* when they are drawn via these TDEStyle primitives to avoid flicker.
|
|
*
|
|
* @li KPE_DockWindowHandle - This primitive is already implemented in TDEStyle,
|
|
* and paints a bevelled rect with the DockWindow caption text. Re-implement
|
|
* this primitive to perform other more fancy effects when drawing the dock window
|
|
* handle.
|
|
*
|
|
* @li KPE_ToolBarHandle - This primitive must be reimplemented. It currently
|
|
* only paints a filled rectangle as default behavior. This primitive is used
|
|
* to render TQToolBar handles.
|
|
*
|
|
* @li KPE_GeneralHandle - This primitive must be reimplemented. It is used
|
|
* to render general handles that are not part of a TQToolBar or TQDockWindow, such
|
|
* as the applet handles used in Kicker. The default implementation paints a filled
|
|
* rect of arbitrary color.
|
|
*
|
|
* @li KPE_SliderGroove - This primitive must be reimplemented. It is used to
|
|
* paint the slider groove. The default implementation paints a filled rect of
|
|
* arbitrary color.
|
|
*
|
|
* @li KPE_SliderHandle - This primitive must be reimplemented. It is used to
|
|
* paint the slider handle. The default implementation paints a filled rect of
|
|
* arbitrary color.
|
|
*
|
|
* @li KPE_ListViewExpander - This primitive is already implemented in TDEStyle. It
|
|
* is used to draw the Expand/Collapse element in TQListViews. To indicate the
|
|
* expanded state, the style flags are set to Style_Off, while Style_On implies collapsed.
|
|
*
|
|
* @li KPE_ListViewBranch - This primitive is already implemented in TDEStyle. It is
|
|
* used to draw the ListView branches where necessary.
