Interface ILcdGLEventListener

All Known Implementing Classes:

ALcdGLEventAdapter

public interface ILcdGLEventListener

Listener for events that applications can respond to by drawing into an ILcdGLDrawable. The drawable's OpenGL context is active when any of the methods in this interface are called, so the application can safely make OpenGL calls.

Method Details

init

void init(ILcdGLDrawable aDrawable)

Called by the ILcdGLDrawable after its OpenGL context has been initialized.

Parameters:

aDrawable - the ILcdGLDrawable

display

void display(ILcdGLDrawable aDrawable)

Called by the ILcdGLDrawable when it requires repainting. The drawable will swap its front and back buffers after the display() methods of all registered ILcdGLEventListeners have been called.

Parameters:

aDrawable - the ILcdGLDrawable

reshape

void reshape(ILcdGLDrawable aDrawable,
 int aX,
 int aY,
 int aWidth,
 int aHeight)

Called by the ILcdGLDrawable when it has been resized.

Parameters:

aDrawable - the ILcdGLDrawable

aX - the new X coordinate of the viewport's lower left corner

aY - the new Y coordinate of the viewport's lower left corner

aWidth - the new width of the viewport

aHeight - the new height of the viewport

dispose

void dispose(ILcdGLDrawable aDrawable)

preDisplay

default void preDisplay(ILcdGLDrawable aDrawable)

postDisplay

default void postDisplay(ILcdGLDrawable aDrawable)
