A popup menu.
Popup menus are used as context menus or as part of a menu bar. Menus are not visible when created. Menus have a name which can be used in event handlers to identify it, and it is used in Menubars as well.
Currently, menu entries are not interpreted in any way. This may change in the future. To ensure upwards compatibility, avoid the '&' character in menu entries, since it may have a special meaning in future versions. Menus use the Font named "menu".
Please note the general remarks in GUI::TransientWindow
| GUI::Menu::Menu | ( | Window * | parent, |
| int | x, | ||
| int | y, | ||
| const STR | name | ||
| ) | [inline] |
Create a menu with given position.
Size is determined dynamically. parent is the logical parent. The true parent object is always the screen the logical parent resides on.
