Widget

└ ContextMenu

Popup menu opened at an arbitrary pointer position.

ContextMenu deliberately resolves the same Menu KSS rule and uses the same layout metrics as MenuBar popups. Context menus therefore keep an identical font, row height and padding in every theme and zoom level.

menu = ContextMenu()
menu.setItems([MenuItem("Open"), MenuItem("Delete")])
menu.selected += lambda(event as ContextMenuEvent): print(event.item.text)
menu.open(0, 0, window.clientWidth, window.clientHeight, mouseX, mouseY)

A pointer press outside the popup closes it automatically. The press is then routed normally to the widget under the pointer. Menus taller than their overlay remain inside it and expose a mouse-wheel scrollbar. The scrollbar supports track clicks and dragging. Up/Down, PageUp/PageDown and Home/End navigate enabled entries and reveal them automatically; Right/Left enter/leave submenus, Enter activates and Escape dismisses. Closing restores the widget that had focus before the menu opened.
