I need oncollapse="" handler see #77506 in the mailnews 3 pane, we have the following optimization: if the message pane is collapsed, we don't load and displaying the message. if the message pane is collapsed, we tell the back end to supress message display. when the message pane is uncollapsed (expanded?) we tell the back end the state has changed and we load the currently selected message. to make sure we don't get into the state where the back end is supressing but the box is expanded, we poke the back end to much. (when the grippy is clicked and onmouseup on the splitter) it's a little tricky, see #77506 ideally, if I could add an oncollapse / onexpand handlers to the messagepane box then I could poke the back end only when the box state changes.
adding hewitt. this seems like something other xul developers would want, or perhaps something like it already exists.
