    }

onClick()

bool MixerSlide::onClick ( Click *  )

inlineoverrideprotectedvirtual

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

Implements ClickHandlerSlide.

Definition at line 66 of file MixerSlide.cpp.

                                        {
        fRect.offset(click->fCurr.fX - click->fPrev.fX,
                     click->fCurr.fY - click->fPrev.fY);
        return true;
    }

onFindClickHandler()

Click * MixerSlide::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.

Definition at line 61 of file MixerSlide.cpp.

                                                                                {

                              SkScalarRoundToInt(y)) ? new Click() : nullptr;
