RE: [platform-swt-dev] Transparent images in Labels

["Rob Hughes" <rhughes@xxxxxxxxxxxxxx>]

In order to get transparency working in a label you have to draw it
yourself.

Label imageLabel = new Label(parent, SWT.NONE);
InputStream is = this.getClass().getResourceAsStream("some.gif");
final Image image = new Image(imageLabel.getDisplay(), is);
imageLabel.addDisposeListener(new DisposeListener()
{
    public void widgetDisposed(DisposeEvent e)
    {
        //get rid of the image when the dialog closes.
        image.dispose();
    }
});
imageLabel.addPaintListener(new PaintListener()
{
    public void paintControl(PaintEvent e)
    {
        e.gc.drawImage(image, 0, 0);
    }
});

Subject: [platform-swt-dev] Transparent images in Labels


If I didn't misunderstand if I load a GIF and put it on a label
(setImage()) I should see the label's background color where the gif's
transparent color is setted.

The gif I'm using is transparent if I put it inside a word document.

Here's how I load the image.

...
InputStream is = this.getClass().getResourceAsStream("some.gif");
return new Image(this.getDisplay(), is);
...

I don't get the transparency effect.
Any thoughts?
