Member Function Documentation

◆ onDisplay()

void ImageKnob::onDisplay ( )

overrideprotectedvirtual

A function called to draw the view contents with OpenGL.

Implements Widget.

◆ onMouse()

bool ImageKnob::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()

bool ImageKnob::onMotion ( const MotionEvent & )

overrideprotectedvirtual

A function called when the pointer moves.

Returns: True to stop event propagation, false otherwise.

Reimplemented from Widget.

◆ onScroll()

bool ImageKnob::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:
