The whole point of documentation is to educate the user, not to make them waste time guessing and trying things. > You could try it, but +runModalForWindow might not invoke -sendEvent: to > dispatch the events it pulls off the event queue within its nested runloop > invocation. I meant using sendEvent for handling all the events for this popup window *instead of* using runModalForWindow, since that won't work for clicks out side the window to dismiss it. > Let's back up to your original question.

I'm not sure how performClickWithFrame helps here. It's documentation says it displays the menu. That's not what I've been asking about. In our NSPopUpButtonCell subclass's trackMouse method, we create a window to display instead of showing the menu. This window has a 3-column NSBrowser in it for displaying a tree type structure. Clicks in column 1 will change what's shown in columns 2 and 3. Clicks in column 2 will change what's shown in column 3. Column 3 is the place where choices are ultimately made. Each column is individually scrollable. So, this control deviates from normal popup usage in that you can't mouseDown/drag/mouseUp to make a choice. A mouseDown/mouseUp shows it, multiple mouseDown/mouseUps can be made until a final mouseDown/mouseUp is made in the 3rd column, or the arrow and return keys can be used to navigate and make a final choice. -- Steve Mills office: 952-818-3871 home: 952-401-6255 cell: 612-803-6157 _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
