问题 I have a NSStatusItem and I want to popup a menu by rightclicking the item. I subclassed a NSView and overwrote the - (void)rightMouseDown:(NSEvent *)event method. I also implemented - (void)mouseDown:(NSEvent *)event for looking at the modifierflags. My problem is, that the view does not recieve the NSRightMouseDown -Event. And I don't know why? Any ideas how to get this event? Naturally I added the custom view to the statusitem. - UPDATE - Additional information: I have added a NSImageView

问题 I just want to add ContextMenu for several objects that I create dynamically, but The only way I found is to create ContextMenu in runtime like this: ContextMenu pMenu = new ContextMenu(); MenuItem item1 = new MenuItem(); MenuItem item2 = new MenuItem(); //I have about 10 items //... item1.Header = "item1"; item1.Click += new RoutedEventHandler(item1_Click); pMenu.Items.Add(item1); item2.Header = "item2"; item2.Click += new RoutedEventHandler(item2_Click); pMenu.Items.Add(item2); //and so on

问题 I currently have a menuitem (part of a context menu), with about ~35 menu items. Because of this, it causes the sub-menu to be huge. Even though I have scrolling ability, I would like to set the height of this submenu while having the ability to still scroll. I've messed w/ the MenuItem.Itemspanel but have not been able to set the sub-menu's height and still scroll. 回答1: Unfortunately, WPF does not allow this to be modified by properties. You will have to modify the default ControlTemplate.

问题 I'd like to add a menu item to the default ContextMenu of a RichTextBox . I could create a new context menu but then I lose the spell check suggestions that show up in the default menu.
