Continuing my quest to understand some of the fine points of menu handling with cascading items in LC, I'm now focusing on popup menus.
The contents of the menu in question are set up dynamically in a mouseDown handler and some data conditions can cause either a checkmark or a diamond to appear immediately before some of the cascading items (all using that standard !c and !r notation). No problem, all works fine. Now the user picks a cascading item from the popup menu and in my menuPick handler, I need to discover if the selected item has a check mark or a diamond before it because my handling of the selected item is different based on their presence or absence. First problem. The parameter to menuPick does not include any indication of whether the selected item has a checkmark or diamond before it. OK says I, that seems strange but no problem, I will use the menuHistory to get the line of the popup menu text that was selected and look for either !c or !r in it. Second problem. The menuHistory contains a line number that does not relate in any way to the line number that was selected. Not even to the primary line that contained the cascading item. In fairness, heaving read the dictionary entry for menuHistory after the fact, it does say that the menuHistory is "ambiguous" for cascading items. "Ambiguous"? Maybe flat out incorrect would have been a better description but by now I've come to realize that stuff like this will never het changed in LC even if it's accepted as a problem because "it might break existing applications". I can think of at least a couple of ways round this problem, by repeating the check that caused the checkmark or diamond to be placed there initially, or by somehow recording the actual text lines that contain a checkmark/diamond in a custom property of the menu. Are there any other recommended ways to get round this?
