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.

The documentation for this class was generated from the following file:
