Member Function Documentation

onDisplay()

template<class ImageType >

void ImageBaseKnob< ImageType >::onDisplay ( )

overrideprotectedvirtual

A function called to draw the widget contents.

Implements Widget.

onMouse()

template<class ImageType >

bool ImageBaseKnob< ImageType >::onMouse ( const MouseEvent &  )

overrideprotectedvirtual

A function called when a mouse button is pressed or released.

Returns

True to stop event propagation, false otherwise.

Reimplemented from Widget.

onMotion()

template<class ImageType >

bool ImageBaseKnob< ImageType >::onMotion ( const MotionEvent &  )

overrideprotectedvirtual

A function called when the pointer moves.

Returns

True to stop event propagation, false otherwise.

Reimplemented from Widget.

onScroll()

template<class ImageType >

bool ImageBaseKnob< ImageType >::onScroll ( const ScrollEvent &  )

overrideprotectedvirtual

A function called on scrolling (e.g. mouse wheel or track pad).

Returns

True to stop event propagation, false otherwise.

Reimplemented from Widget.
