public abstract class QIconEngineV2
- extends QIconEngine
The QIconEngineV2 class provides an abstract base class for QIcon
renderers. An icon engine renders QIcon
s. With icon engines, you can customize icons. Qt provides a default engine that makes icons adhere to the current style by scaling the icons and providing a disabled appearance.
An engine is installed on an icon either through a QIcon
constructor or through a QIconEnginePluginV2
. The plugins are used by Qt if a specific engine is not given when the icon is created. See the QIconEngineV2 class description to learn how to create icon engine plugins.
An icon engine provides the rendering functions for a QIcon
. Each icon has a corresponding icon engine that is responsible for drawing the icon with a requested size, mode and state.
QIconEngineV2 extends the API of QIconEngine
to allow streaming of the icon engine contents, and should be used instead of QIconEngine
for implementing new icon engines.

public QIconEngineV2()
clone
public QIconEngineV2 clone()
- This method is reimplemented for internal reasons
- Overrides:
clone
in class java.lang.Object
key
public java.lang.String key()
- Returns a key that identifies this icon engine.
read
public boolean read(QDataStream in)
- Reads icon engine contents from the
QDataStream
in. Returns true if the contents were read; otherwise returns false. QIconEngineV2's default implementation always return false.
write
public boolean write(QDataStream out)
- Writes the contents of this engine to the
QDataStream
out. Returns true if the contents were written; otherwise returns false. QIconEngineV2's default implementation always return false.
