I'm trying to show custom popup menu at text cursor position in editor. So I create a command and key binding then add command handler where I creates popup menu and open it. But how can I get text cursor position to show my popup at cursor?

do you mean the line number in the opened document where the cursor is currently positioned?

The current position of your cursor is represented by the offset. When you are in an text editor you can get the ITextEditor like that:


public static ITextEditor getITextEditor(IEditorPart editor) {
		ITextEditor textEditor = null;
		if (editor instanceof ITextEditor) {
			textEditor = (ITextEditor) editor;
		} else {
			textEditor = (ITextEditor) editor.getAdapter(ITextEditor.class);
		}
		return textEditor;
	}


When you have the text editor you can get the ITextSelection and in there the offset.

If you use a handler this might give you the neccessary selection where you find the offset:

HandlerUtil.getCurrentSelection(event)


Best,
Artur

Yep, I know how to get offset. But I don't know how to convert offset to exact position in pixels (x,y).

Hello NG,
I have the same problem. Is it possible anyhow to resolve the current x
and y coordinates in pixels for the current cursor position in a text
editor for displaying a tooltip at?

best regards,
Gilbert
