Detailed Description

Basic implementation of the ICursorProvider interface, representing the connection between a region on the screen and the cursor to be used when withing that region. Implementors of ICursorProvider should either derive from either this, or just use SimpleCursorProvider.

Member Function Documentation

virtual CursorSpec CCursorProvider::GetCursor ( IControlView *  viewUnderMouse, const SysPoint  globalLocation, ICursorMgr::eCursorModifierState  modifiers  ) const

virtual

Default behavior: returns kCrsrPointer

Implements ICursorProvider.

Reimplemented in CToolCursorProvider, and SnapCursorProvider.

virtual bool16 CCursorProvider::HasLockedState ( ) const

virtual

Default behavior: returns kTrue

Implements ICursorProvider.

Reimplemented in CToolCursorProvider.

virtual bool16 CCursorProvider::LocationAffectsCursor ( SysRgn  cursorRgn ) const

virtual

Default behavior: returns kFalse

Implements ICursorProvider.

virtual bool16 CCursorProvider::ModifiersAffectCursor ( SysRgn  cursorRgn ) const

virtual

Default behavior: returns kFalse

Implements ICursorProvider.

Reimplemented in CToolCursorProvider.

virtual void CCursorProvider::SetSingleCursor ( const CursorSpec &  )

virtual

Default behavior: does nothing. In debug builds, this asserts when called unless overridden. The SimpleCursorProvider implementation is intended for providers involving only a single cursor.

Implements ICursorProvider.
