I can add an icon URI HandleToolItem. Where can I add the disabled icon? I only get the OS grayed icons.

You can add hints to the MHandledToolItem's transientData using the keys defined on

org.eclipse.e4.ui.workbench.IPresentationEngine#DISABLED_ICON_IMAGE_KEY

.

I know that, but I want to add this information at modeling time (in the application model). Transient data is available at runtime only.

Hello,

for my own reference and as a possible solution to others. I've found a workaround where the disabled Icon URI can be set in the application model similar to the normal icon URI:

Add a tag on the Supplementary tab like:

e4_disabled_icon_image_key=platform:/plugin/de.credo.{...}/hand_touch.png

where e4_disabled_icon_image_key is the constant value for IPresentationEngine.DISABLED_ICON_IMAGE_KEY. Do this with all of your icons which require special disabled icon versions.

Place the following code for example in the @PostConstruct routine of your part's code, inject MWindow and you're done. This routine copies tag values with known names (here: IPresentationEngine.DISABLED_ICON_IMAGE_KEY) to the relevant TransientData map.

	for (MTrimBar trimBar: window.getTrimBars()) {
		for (MTrimElement toolBar: trimBar.getChildren()) {
			if (toolBar instanceof MToolBar) {
				for (MToolBarElement toolBarElement: ((MToolBar) toolBar).getChildren()) {
					for (String tag: toolBarElement.getTags()) {
						if (tag.startsWith(IPresentationEngine.DISABLED_ICON_IMAGE_KEY)) {
							String disabledIconURI = tag.substring(IPresentationEngine.DISABLED_ICON_IMAGE_KEY.length() + 1);
							toolBarElement.getTransientData().put(IPresentationEngine.DISABLED_ICON_IMAGE_KEY, disabledIconURI);
						}
					}
				}
			}
		}
	}

Regards
Guido
