- add_button(button: ButtonHandle) → bool
Adds the indicated button to the set of buttons that will be monitored for upness and downness. Returns true if the button was added, false if it was already being monitored or if too many buttons are currently being monitored.
- all_buttons_up()
Marks all monitored buttons as being in the “up” state.
- assign(copy: ModifierButtons) → ModifierButtons
- button_down(button: ButtonHandle) → bool
Records that a particular button has been pressed. If the given button is one of the buttons that is currently being monitored, this will update the internal state appropriately; otherwise, it will do nothing. Returns true if the button is one that was monitored, or false otherwise.
- button_up(button: ButtonHandle) → bool
Records that a particular button has been released. If the given button is one of the buttons that is currently being monitored, this will update the internal state appropriately; otherwise, it will do nothing. Returns true if the button is one that was monitored, or false otherwise.
- property buttons → Sequence[ButtonHandle]
Returns the nth button that the
ModifierButtonsobject is monitoring (the nth button passed toadd_button()). This must be in the range 0 <= index <get_num_buttons().
- get_button(index: int) → ButtonHandle
Returns the nth button that the
ModifierButtonsobject is monitoring (the nth button passed toadd_button()). This must be in the range 0 <= index <get_num_buttons().
- get_num_buttons() → int
Returns the number of buttons that the
ModifierButtonsobject is monitoring (e.g. the number of buttons passed toadd_button()).
- get_prefix() → str
Returns a string which can be used to prefix any button name or event name with the unique set of modifier buttons currently being held.
- has_button(button: ButtonHandle) → bool
Returns true if the indicated button is in the set of buttons being monitored, false otherwise.
- is_any_down() → bool
Returns true if any of the tracked button are known to be down, or false if all of them are up.
- is_down(button: ButtonHandle) → bool
Returns true if the indicated button is known to be down, or false if it is known to be up or if it is not in the set of buttons being tracked.
- is_down(index: int) → bool
Returns true if the indicated button is known to be down, or false if it is known to be up.
- matches(other: ModifierButtons) → bool
Returns true if the set of buttons indicated as down by this
ModifierButtonsobject is the same set of buttons indicated as down by the otherModifierButtonsobject. The buttons indicated as up are not relevant.
- remove_button(button: ButtonHandle) → bool
Removes the indicated button from the set of buttons being monitored. Returns true if the button was removed, false if it was not being monitored in the first place.
Unlike the other methods, you cannot remove a button by removing its alias; you have to remove exactly the button itself.
- set_button_list(other: ModifierButtons)
Sets the list of buttons to watch to be the same as that of the other
ModifierButtonsobject. This makes the lists pointer equivalent (until one or the other is later modified).This will preserve the state of any button that was on the original list and is also on the new lists. Any other buttons will get reset to the default state of “up”.
