onChar()

bool HalfPlaneSlide3::onChar ( SkUnichar  uni )

inlineoverridevirtual

Reimplemented from CameraSlide.

Definition at line 512 of file ClipSlide.cpp.

onClick()

bool HalfPlaneSlide3::onClick ( Click *  )

inlineoverrideprotectedvirtual

Override to track clicks. Return true as long as you want to track the pen/mouse.

Implements ClickHandlerSlide.
