onClick()

bool SlidesSlide::onClick ( ClickHandlerSlide::Click *  )

inlineoverrideprotectedvirtual

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

Implements ClickHandlerSlide.

{ return false; }

onFindClickHandler()

Click * SlidesSlide::onFindClickHandler ( SkScalar  x, SkScalar  y, skui::ModifierKey  modi  )

inlineoverrideprotectedvirtual

Return a Click object to handle the click. onClick will be called repeatedly with the latest mouse state tracked on the Click object until it returns false.

Implements ClickHandlerSlide.
