Detailed Description

UPopmenu: Contextual Menu.

UPopmenu objects are NOT automatically OPENED by their parent(s). There a two ways for opening Popmenus:

• 1) by using the UPopmenu::autoOpens() method
• 2) by adding appropriate callbacks to menu openers (see example below)

Note: as other Ubit UBricks, menus MUST HAVE at least one parent.

See also classes: UWin, UMenu.

Example (see also method: autoOpens()) :

  opener.addlist(menu + UOn::mpress / ucall(&menu, openMenu))

  void openMenu(UEvent& e, UPopmenu* pop) {
       popmenu->move(e, 0, 0);  // move the menu to Event location
       popmenu->open();         // open the menu
   }

Member Function Documentation

void UPopmenu::autoOpens (  UBox &  opener, const std::vector< InputCond > &  , bool  children_open_menu )  [virtual]

this 'opener' will automatically open the menu Arguments: 'button_mask' indicate which mouse buttons open the menu when pressed. It's an ORed combination of UEvent::MButton1, UEvent::MButton2, etc. if 'keysym' is not null it indicates which X keysym (= which logical key on the keyboard) opens the menu when pressed. 'children_open_menu' means that the menu is always opened, even if the event is located inside a child of the opener (default is false).
