Member Function Documentation

DeleteThis()

virtual void IRhRdkAngleDialDecorator::DeleteThis ( void  )

pure virtual

You must implement this method as

delete this; 

DialColors()

virtual void IRhRdkAngleDialDecorator::DialColors ( CRhRdkColor &  colOut1, CRhRdkColor &  colOut2  ) const

pure virtual

Implement this method to override the default dial colors when the style is kUnmarked, kCompass or kAzimuth. If you don't want to override the dial colors, implement a no-op stub.

See also

CRhRdkAngleCtrl::SetDialColors().

Draw()

virtual void IRhRdkAngleDialDecorator::Draw ( HDC  dc, const ON_4iRect &  dialRect, double  dRadius, double  dAngle, bool  bEnabled, bool  bHot  ) const

pure virtual

Implement this method to draw the decoration.

Parameters

dc	is the device context to draw into.
dialRect	is the rectangle of the dial.
dRadius	is the radius of the dial.
dAngle	is the angle being displayed by the control.
bEnabled	is true if the control is enabled, else false.
bHot	is true if the decoration should be drawn in hot-tracked style.

EVF()

virtual void* IRhRdkAngleDialDecorator::EVF ( const wchar_t *  , void *    )

pure virtual

Emergency virtual function for future expansion.

NextDecorator()

virtual IRhRdkAngleDialDecorator* IRhRdkAngleDialDecorator::NextDecorator ( void  ) const

pure virtual

Implement this method to return a pointer to an optional next decorator. This allows decorators to be chained together. Return null if not needed.
