type ContextMenu struct {
// contains filtered or unexported fields
}ContextMenu paints an application-positioned menu without owning pointer, keyboard, or popup lifecycle state. PlaceOverlay, given a zero-size anchor at the pointer, places it with the flip a context menu needs next to a window edge.
BeginContextMenu#func BeginContextMenu(canvas *ui.Canvas, theme ui.Theme, bounds ui.Rect, options ContextMenuOptions) ContextMenuBeginContextMenu paints an open menu at the caller's context-menu position, using caller-owned layer, focus scope, and Escape action identities. Bounds are normalized to Vega's 9rem minimum (8rem for a submenu).
AddItem#func (menu *ContextMenu) AddItem(item ContextMenuItem) ui.RectAddItem paints one action, checkbox, radio option, or submenu trigger. The rectangle is empty when the row is scrolled out of the menu.
AddItemSlot#func (menu *ContextMenu) AddItemSlot(item ContextMenuItem) (row, slot ui.Rect)AddItemSlot paints an item like AddItem and also returns the rectangle its TrailingWidth reserved, vertically centered in the row and ending 8px from its edge. The slot is empty when the item has no TrailingWidth or is scrolled out of the menu. Paint into it between BeginContent and EndContent.
AddLabel#func (menu *ContextMenu) AddLabel(label string, inset bool) ui.RectAddLabel paints one medium-weight group label and returns its row geometry.
AddSeparator#func (menu *ContextMenu) AddSeparator() ui.RectAddSeparator paints the official -mx-1/my-1 divider geometry.
BeginContent#func (menu *ContextMenu) BeginContent()BeginContent enters the menu's layer and focus scope so the caller's own components, painted until EndContent, belong to the menu: above the page, inside its focus trap, and hit-tested over the row beneath.
Bounds#func (menu ContextMenu) Bounds() ui.RectBounds returns the normalized overlay geometry.
End#func (menu *ContextMenu) End()End paints the scrollbar of a menu whose items did not all fit, after the last item: call it once the last item is painted.
EndContent#func (menu *ContextMenu) EndContent()EndContent leaves the layer and focus scope BeginContent entered.
NextItemBounds#func (menu ContextMenu) NextItemBounds() ui.RectNextItemBounds returns the next keyboard-navigation row (RowHeight high) without advancing the declaration cursor.
