Examples with GLCanvas org.eclipse.swt.opengl.GLCanvas used on opensource projects

Example 1 with GLCanvas

use of org.eclipse.swt.opengl.GLCanvas in project lwjgl by LWJGL.

the class LWJGLInfoView method createPartControl.

/** 
	 * {@inheritDoc}
	 * @see org.eclipse.ui.part.WorkbenchPart#createPartControl(org.eclipse.swt.widgets.Composite)
	 */
@Override
public void createPartControl(Composite i_parent) {
    Text info = new Text(i_parent, SWT.READ_ONLY | SWT.LEFT | SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL);
    GLCanvas canvas = new GLCanvas(i_parent, SWT.NONE, new GLData());
    canvas.setCurrent();
    try {
        GLContext.useContext(canvas);
    } catch (LWJGLException ex) {
        // TODO Implement catch block for LWJGLException
        ex.printStackTrace();
    }
    String infoString = gatherInformation();
    info.setText(infoString);
}
