Word wrap on ConfigurableCompletionProposal tooltips - how? [message #1053330]

A very simple question. How do I enable word-wrap on the detail of completion proposals (see attached screenshot). Currently all of my proposal details are being clipped off-screen.

Code:

I'm using the following constructor to construct my completion proposals:

ConfigurableCompletionProposal completionProposal = new ConfigurableCompletionProposal(templateId,  context.getOffset() - prefix.length(),prefix.length(),templateId.length(), null /* Image */ ,new StyledString(templateId),null,templateDescription);

Hi,

we subclassed DefaultInformationControl and changed setVisible as follows

	@Override
	public void setVisible(boolean visible) {
		if (getShell().isVisible() == visible) {
			return;
		}
		getShell().setVisible(visible);
	}

then we extended XtextSourceViewerConfiguration to hook in the new class

	@Override
	public IInformationControlCreator getInformationControlCreator(ISourceViewer sourceViewer) {
		return new IInformationControlCreator() {
			@Override
			public IInformationControl createInformationControl(Shell parent) {
				return new BasisDefaultInformationControl(parent, SWT.TOOL | SWT.ON_TOP, SWT.WRAP, null, null);
			}
		};
	}

Thanks Christian. That worked.

I'm very happy indeed.

And I know its obvious to non-beginners, but for beginners reading this thread, you also have to add this to your YourAppNameUIModule.java

	public Class<? extends XtextSourceViewerConfiguration> bindXtextSourceViewerConfiguration() {
		return YourAppNameSourceViewerConfiguration.class;
	}
