Detailed Description

template<class ImageType>
class ImageBaseButton< ImageType >

DGL Image Button class.

This is a typical button, where the drawing comes from a pregenerated set of images. The button can be under "normal", "hover" and "down" states, with one separate image possible for each.

The event logic for this button comes from the ButtonEventHandler class.

Member Function Documentation

◆ onDisplay()

template<class ImageType >

void ImageBaseButton< ImageType >::onDisplay ( )

overrideprotectedvirtual

A function called to draw the widget contents.

Implements Widget.

◆ onMouse()

template<class ImageType >

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

overrideprotectedvirtual

A function called when the pointer moves.

Returns: True to stop event propagation, false otherwise.

Reimplemented from Widget.

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

dgl/ImageBaseWidgets.hpp
