SWT/AWT flickering problem [message #464023]

Originally posted by: nlupanov.outsourcingbg.com

I am integrating existing Swing gui into Eclipse plugin - therefore i use
the
SWT_AWT.new_Frame() method to gain java.awt.Frame class and add swing
component to it.
This is the code of the eclipse plugin view:

public class ETL4ALLWorkerView extends ViewPart {

public static final String ID = "EclipsePluginETL4ALL.WorkerView";
Frame frame;
Composite swt_frame;
Canvas canvas;
public ETL4ALLWorkerView() {
super();
}

public void createPartControl(Composite parent) {

swt_frame = new Composite(parent, SWT.EMBEDDED | SWT.NO_REDRAW_RESIZE);
frame = SWT_AWT.new_Frame(swt_frame);
TransformClient clientFrame = null;
if((clientFrame = Perspective.getETL4ALLMainFrame()) == null){
clientFrame = TransformClient.plugin_main();
Perspective.setETL4ALLMainFrame(clientFrame);
}

//The following is a JDesktopPane that i use to add JInternalFrames to:
WorkerPanel workerPane = clientFrame.getWorkerPane();
frame.setBackground(new Color(180,70,220));
frame.add(workerPane);

public void setFocus() {

}

}

I am trying to add the swing JDesktopPane to java.awt.Frame .The
JDesktopPane includes
JInternalFrame.The problem is that the GUI is flickering when resized or
moved.
I migrated from jre1.4 to jre1.5 and the flickering of the JDesktopPane
stops but the
JInternalFrame is still flickering when resized/moved.I am wondering if at
this point this is
a SWT/Swing integration issue or AWT/Swing issue.

Following the example of this snippet may help:

http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.sni ppets/src/org/eclipse/swt/snippets/Snippet154.java?rev=HEAD& amp;content-type=text/vnd.viewcvs-markup

If you setup a root pane and possibly set the sun.awt.noerasebackground
property, flicker will be reduced (but, in my experience, not completely
eliminated).

Have you actually seen improvements with the early Mustang releases?

I noticed this bug fix too, and hoped it would help... but I didn't
really see a difference when I tried running with recent Mustang builds.

I am aware with this example it it still does not help.I am trying to embedd
a swing JDesktopPane into java.awt.Frame that is integrated with the SWT
Composite object of the plugin view.Another think i have noticed is that it
flickers with the java.awt.Frame's background so maybe it is an AWT/Swing
issue.
