Class CCoeScreenDeviceChangeDefaultHandler

class CCoeScreenDeviceChangeDefaultHandler : public CCoeStatic;

Description

A default screen device change handler.

This class is used to activate a default view when a screen "flip" occurs, if the currently active view does not implement MCoeView::ViewScreenDeviceChangedL().

Derivation

• CBase - Base class for all classes to be instantiated on the heap.

• CCoeStatic - Base class for creating singleton objects that will be stored by CCoeEnv.

• CCoeScreenDeviceChangeDefaultHandler - A default screen device change handler.

IMPORT_C ~CCoeScreenDeviceChangeDefaultHandler();

Description

Destructor.

protected: IMPORT_C CCoeScreenDeviceChangeDefaultHandler();

Description

Default constructor.

protected: IMPORT_C CCoeScreenDeviceChangeDefaultHandler(TInt aDestructionPriority);

Description

Constructor specifying the destruction priority of the object.

Parameters

TInt aDestructionPriority Priority determining the order of destruction relative to other CCoeStatic-derived objects. The higher the destruction-priority of the object, the earlier that object is deleted. Objects with a positive destruction-priority are destroyed before the CCoeAppUi object is destroyed. Objects with a negative destruction-priority are destroyed after the CCoeAppUi object is destroyed.
