Class MCoeControlHitTest

class MCoeControlHitTest;

Description

Abstract interface for defining a control's hit region.

This could be implemented by a CCoeControl-derived class to define hit region checking. The object is installed by calling CCoeControl::SetHitTest().

The hit region is the area inside the control's rectangle in which pointer events are handled. It can be any shape, not necessarily rectangular.

Members

Defined in MCoeControlHitTest:
HitRegionContains(), MCoeControlHitTest(), MCoeControlHitTest_Reserved1(), MCoeControlHitTest_Reserved2()

protected: IMPORT_C MCoeControlHitTest();

Description

virtual TBool HitRegionContains(const TPoint &aPoint, const CCoeControl &aControl) const=0;

Description

Tests whether a pointer event occurred inside the control's hit region. This function is called by CCoeControl::HandlePointerEventL().

Parameters

const TPoint &aPoint The position of the pointer event. const CCoeControl &aControl

Return value

TBool ETrue if the specified point lies inside the hit region, EFalse if not.
