Here is the caller graph for this function:

◆ display()

void com.jogamp.newt.util.applet.JOGLNewtAppletBase.display ( final GLAutoDrawable  drawable)

Called by the drawable to initiate OpenGL rendering by the client.

After all GLEventListeners have been notified of a display event, the drawable will swap its buffers if setAutoSwapBufferMode is enabled.

Implements com.jogamp.opengl.GLEventListener.

Definition at line 295 of file JOGLNewtAppletBase.java.

◆ dispose()

void com.jogamp.newt.util.applet.JOGLNewtAppletBase.dispose ( final GLAutoDrawable  drawable)

Notifies the listener to perform the release of all OpenGL resources per GLContext, such as memory buffers and GLSL programs.

Called by the drawable before the OpenGL context is destroyed by an external event, like a reconfiguration of the GLAutoDrawable closing an attached window, but also manually by calling destroy.

Note that this event does not imply the end of life of the application. It could be produced with a followup call to init(GLAutoDrawable) in case the GLContext has been recreated, e.g. due to a pixel configuration change in a multihead environment.

◆ init() [1/3]

void com.jogamp.newt.util.applet.JOGLNewtAppletBase.init ( final GLAutoDrawable  drawable)

Called by the drawable immediately after the OpenGL context is initialized.

Can be used to perform one-time OpenGL initialization per GLContext, such as setup of lights and display lists.

Note that this method may be called more than once if the underlying OpenGL context for the GLAutoDrawable is destroyed and recreated, for example if a GLCanvas is removed from the widget hierarchy and later added again.

◆ keyPressed()

void com.jogamp.newt.util.applet.JOGLNewtAppletBase.keyPressed ( final KeyEvent  e)

A key has been pressed, excluding auto-repeat modifier keys.

See KeyEvent.

◆ keyReleased()

void com.jogamp.newt.util.applet.JOGLNewtAppletBase.keyReleased ( final KeyEvent  e)

A key has been released, excluding auto-repeat modifier keys.

See KeyEvent.

To simulated the removed keyTyped(KeyEvent e) semantics, simply apply the following constraints upfront and bail out if not matched, i.e.:

 if( !e.isPrintableKey() || e.isAutoRepeat() ) {
     return;
 }

Definition at line 337 of file JOGLNewtAppletBase.java.

◆ reshape()

void com.jogamp.newt.util.applet.JOGLNewtAppletBase.reshape ( final GLAutoDrawable  drawable,
final int  x,
final int  y,
final int  width,
final int  height 
)

Called by the drawable during the first repaint after the component has been resized.

The client can update it's viewport associated data and view volume of the window appropriately.

For efficiency the GL viewport has already been updated via glViewport(x, y, width, height) when this method is called.

Parameters
drawablethe triggering GLAutoDrawable
xlower left corner of the viewport rectangle in pixel units
ylower left corner of the viewport rectangle in pixel units
widthwidth of the viewport rectangle in pixel units
heightheight of the viewport rectangle in pixel units
