52.1. Classes defined in module gui.menu¶
-
class
gui.menu.
BaseMenu
(title='AMenu', parent=None, before=None, items=None)[source]¶ A general menu class.
A hierarchical menu that keeps a list of its item names and actions. The item names are normalized by removing all ‘&’ characters and converting the result to lower case. It thus becomes easy to search for an existing item in a menu.
This class is not intended for direct use, but through subclasses. Subclasses should implement at least the following methods:
addSeparator()
insertSeperator(before)
addAction(text,action)
insertAction(before,text,action)
addMenu(text,menu)
insertMenu(before,text,menu)
QtWidgets.Menu and QtWidgets.MenuBar provide these methods.
-
class
gui.menu.
Menu
(title='UserMenu', parent=None, before=None, tearoff=False, items=None)[source]¶ A popup/pulldown menu.
-
class
gui.menu.
DAction
(name, icon=None, data=None, signal=None)[source]¶ A DAction is a QAction that emits a signal with a string parameter.
When triggered, this action sends a signal (default ‘CLICKED’) with a custom string as parameter. The connected slot can then act depending on this parameter.
-
class
gui.menu.
ActionList
(actions=[], function=None, menu=None, toolbar=None, icons=None, text=None)[source]¶ Menu and toolbar with named actions.
An action list is a list of strings, each connected to some action. The actions can be presented in a menu and/or a toolbar. On activating one of the menu or toolbar buttons, a given signal is emitted with the button string as parameter. A fixed function can be connected to this signal to act dependent on the string value.
