PopupMenu

继承： Popup < Window < Viewport < Node < Object

A modal window used to display a list of options.

描述

PopupMenu is a modal window used to display a list of options. Useful for toolbars and context menus.

The size of a PopupMenu can be limited by using Window.max_size. If the height of the list of items is larger than the maximum height of the PopupMenu, a ScrollContainer within the popup will allow the user to scroll the contents. If no maximum size is set, or if it is set to 0, the PopupMenu height will be limited by its parent rect.

All set_* methods allow negative item indices, i.e. -1 to access the last item, -2 to select the second-to-last item, and so on.

Incremental search: Like ItemList and Tree, PopupMenu supports searching within the list while the control is focused. Press a key that matches the first letter of an item's name to select the first item starting with the given letter. After that point, there are two ways to perform incremental search: 1) Press the same key again before the timeout duration to select the next item starting with the same letter. 2) Press letter keys that match the rest of the word before the timeout duration to match to select the item in question directly. Both of these actions will be reset to the beginning of the list if the timeout duration has passed since the last keystroke was registered. You can adjust the timeout duration by changing ProjectSettings.gui/timers/incremental_search_max_interval_msec.

Note: The ID values used for items are limited to 32 bits, not full 64 bits of int. This has a range of -2^32 to 2^32 - 1, i.e. -2147483648 to 2147483647.

方法说明

bool activate_item_by_event ( event: InputEvent, for_global_only: bool = false )

Checks the provided event against the PopupMenu's shortcuts and accelerators, and activates the first item with matching events. If for_global_only is true, only shortcuts and accelerators with global set to true will be called.

Returns true if an item was successfully activated.

Note: Certain Control s, such as MenuButton, will call this method automatically.

void add_check_item ( label: String, id: int = -1, accel: Key = 0 )

Adds a new checkable item with text label.

An id can optionally be provided, as well as an accelerator (accel). If no id is provided, one will be created from the index. If no accel is provided, then the default value of 0 (corresponding to @GlobalScope.KEY_NONE) will be assigned to the item (which means it won't have any accelerator). See get_item_accelerator for more info on accelerators.

Note: Checkable items just display a checkmark, but don't have any built-in checking behavior and must be checked/unchecked manually. See set_item_checked for more info on how to control it.

void add_check_shortcut ( shortcut: Shortcut, id: int = -1, global: bool = false )

Adds a new checkable item and assigns the specified Shortcut to it. Sets the label of the checkbox to the Shortcut's name.

An id can optionally be provided. If no id is provided, one will be created from the index.

Note: Checkable items just display a checkmark, but don't have any built-in checking behavior and must be checked/unchecked manually. See set_item_checked for more info on how to control it.
