Detailed Description
Simplifies and extends the QStyle API to make style coding easier.The KStyle class provides a simple internal menu transparency engine which attempts to use XRender for accelerated blending where requested, or falls back to fast internal software tinting/blending routines. It also simplifies more complex portions of the QStyle API, such as the PopupMenuItems, ScrollBars and Sliders by providing extra "primitive elements" which are simple to implement by the style writer.

KStyle ScrollBarType:. Allows the style writer to easily select what type of scrollbar should be used without having to duplicate large amounts of source code by implementing the complex control CC_ScrollBar.

|
KStyle Primitive Elements:. The KStyle class extends the Qt's Style API by providing certain simplifications for parts of QStyle. To do this, the KStylePrimitive elements were defined, which are very similar to Qt's PrimitiveElement. The first three Handle primitives simplify and extend PE_DockWindowHandle, so do not reimplement PE_DockWindowHandle if you want the KStyle handle simplifications to be operable. Similarly do not reimplement CC_Slider, SC_SliderGroove and SC_SliderHandle when using the KStyle slider primitives. KStyle automatically double-buffers slider painting when they are drawn via these KStyle primitives to avoid flicker.

Constructor & Destructor Documentation
|
Constructs a KStyle object. Select the appropriate KStyle flags and scrollbar type for your style. The user's style preferences selected in KControl are read by using QSettings and are automatically applied to the style. As a fallback, KStyle paints progressbars and tabbars. It inherits from QCommonStyle for speed, so don't expect much to be implemented. It is advisable to use a currently implemented style such as the HighColor style as a foundation for any new KStyle, so the limited number of drawing fallbacks should not prove problematic.

Returns the default widget style depending on color depth.

|
Modifies the scrollbar type used by the style. This function is only provided for convenience. It allows you to make a late decision about what scrollbar type to use for the style after performing some processing in your style's constructor. In most situations however, setting the scrollbar type via the KStyle constructor should suffice. Definition at line 271 of file kstyle.cpp. |
|
Returns the KStyle flags used to initialise the style. This is used solely for the kcmstyle module, and hence is internal. Definition at line 276 of file kstyle.cpp. References KStyleFlags. |

This virtual function defines the pixmap used to blend between the popup menu and the background to create different menu transparency effects. For example, you can fill the pixmap "pix" with a gradient based on the popup's colorGroup, a texture, or some other fancy painting routine. KStyle will then internally blend this pixmap with a snapshot of the background behind the popupMenu to create the illusion of transparency. This virtual is never called if XRender/Software blending is disabled by the user in KDE's style control module.
