Java Forum / GUI / January 2004jEditorPane and getCaretPosition in HTML frames
Hello. :-) I've got a problem: when I'm viewing a HTML document that contains frames via a jEditorPane, the getCaretPosition method always returns 0. But if I view a HTML document that doesn't contain frames, getCaretPosition returns what I would expect it to. Is this a bug or am I missing something? I'm assuming here that I don't have go hunting through the frames of a document, do I? And if that's the case, how? If it's a bug, then can I somehow intercept the loading of frames and render them myself as individual documents?

Hmmm... They *are* rendered as individual documents in individual JEditorPane descendants of the JEditorPane displaying the frameset. Each frame has its own caret and thus its own caret position.

If that's so, how is it possible to query a caret position from a particular frame? >> > I've got a problem: when I'm viewing a HTML document that >> > contains frames via a jEditorPane, the getCaretPosition method [quoted text clipped - 12 lines] > If that's so, how is it possible to query a caret position from a particular > frame? Search for its editor pane: Find the element represent the frame (AttributeSet.NameAttribute == HTML.Tag.FRAME) find the corresponding ComponentView, use its getComponent, then search until you find its JEditorPane.
