Member Function Documentation

void TArcSliderControl2::CompatibleDraw ( RgnHandle inLimitRgn,

CGContextRef inContext,

bool inCompositing

) [protected, virtual]

The fun part of the control.
XXX need to test with vertically oriented images
Reimplemented from TSliderControl.

void TArcSliderControl2::DrawStaticBackground ( RgnHandle inLimitRgn,

CGContextRef inContext,

bool inCompositing

) [protected, virtual]

The fun part of the control.
XXX need to test with vertically oriented images
Reimplemented from TSliderControl.

void TArcSliderControl2::EraseBackground ( CGContextRef inContext,

bool inCompositing

) [protected, virtual]

Reimplemented from TViewNoCompositingCompatible.

bool TArcSliderControl2::GetProperty ( OSType propID,

double & value

) [virtual]

Reimplemented from TSliderControl.

virtual bool TArcSliderControl2::Prerender ( ) [inline, protected, virtual]

Reimplemented from TViewNoCompositingCompatible.

void TArcSliderControl2::SetProperty ( OSType propID,

double value

) [virtual]

Reimplemented from TSliderControl.

OSStatus TArcSliderControl2::StartTracking ( TCarbonEvent & inEvent,

HIPoint & from

) [protected, virtual]

Called before tracking.
The new control value is calculated so that the slider thumb ends up centered on the mouse. This takes into account all of the inset and size values, and also considers the background image and thumb orientation compared to the slider orientation.
Reimplemented from TSliderControl.

OSStatus TArcSliderControl2::StillTracking ( TCarbonEvent & inEvent,

HIPoint & from

) [protected, virtual]

Called during mouse tracking.
Works basically the same as the StartTracking() member function, except that thus function also calculates the amount of control value change based on how much the mouse position has changed since the last call to StillTracking(). This delta value is used for the control and option key modifiers, for higher precision slider control.
Reimplemented from TSliderControl.
