[platform-swt-dev] Flickering on Resize using lwjgl
|
Dear all,
after googling and searching mailing list archives, i decide to join
this mailing list to ask for help.
We are developing a video player using Eclipse RCP/SWT/lwjgl:
Our current eclipse version is:
3.5.2.R35x_v20100210-0800-9hEiFzmFst-TiEn9hNYgDWg1XN8ulH_JvCNGB
OS is: Windows 7
We have some flickering problems when there is a resize event.
There is a factory class that return a GLCanvas/Composite depending on
preferences
....
public static Composite getVideoPlaybackStage(Composite parent,
VideoModel vm, MediaPlayerModel model)
{
IPreferenceStore store = Activator.getDefault().getPreferenceStore();
boolean isOpenGL = store.getBoolean(VideoPreferencesCostants.OPEN_GL);
Composite stage = createStage(parent, isOpenGL);
VideoRepainter vrp = new VideoRepainter(stage, vm, model, isOpenGL);
stage.setLayoutData(new GridData(GridData.FILL_BOTH));
stage.addPaintListener(vrp);
return stage;
}
private static Composite createStage(Composite parent, boolean isOpenGL)
{
Composite stage;
if (isOpenGL)
{
GLData glData = new GLData();
glData.doubleBuffer = true;
stage = new GLCanvas(parent, SWT.NO_BACKGROUND , glData);
}
else
{
stage = new Composite(parent, isMicrosoftWindows() ?
SWT.DOUBLE_BUFFERED : SWT.NONE);
stage.setBackground(Colors.BLACK);
}
return stage;
}
....
and a class (VideoRepainter: http://snipt.org/ngkki/) which is in
charge to actually repaint the composite/canvas
We can solve the repaint flickering on resize using SWT.NONE instead
of SWT.NO_BACKGROUND but the final result is worst,
because the background color is visible every 5/6 frame.
Do you have any suggestion?
Thanks in advance and I'm looking to hear news from you soon.
Regards,
Daniele
