I have the impression that the transparancy set in a style is ignored.
When i register a style with transparency like this:
public static Style getStyleForOverlay(Diagram diagram) {
final String styleId = "OVERLAY"; //$NON-NLS-1$
Style style = findStyle(diagram, styleId);
IGaService gaService = Graphiti.getGaService();
if (style == null) { // style not found - create new style
style = gaService.createStyle(diagram, styleId);
...
style.setTransparency(0.7d);
}
return style;
}
A Figure is not transparent:
Rectangle rectangle = gaService.createRectangle(...);
....
rectangle.setStyle(StyleUtil.getStyleForOverlay(diagram));
only if i add:
rectangle.setTransparency(0.7d);
Is this an issue or am I doing something wrong?
Thanks in advance
Veit
