Adding Menu Actions

You can add actions to the default menu bar in 2 ways:

• Add any custom action to the “Actions” drop down

• Add a “save”, “save as”, and/or “load” function to the “File” drop down

To add to the menu bar, overload the menu_items() and file_menu_items() functions in your Display subclass. These functions should return dictionaries, where the keys are the action names, and the values one of the following:

• A callable

• A two element tuple, where the first item is a callable and the second is a keyboard shortcut

• A dictionary corresponding to a sub menu, with the same key-value format so far described. This is only available for the “Actions” menu, not for the “File” menu

Note

The only accepted keys for the “File” menu are: “save”, “save_as”, and “load”

An example:

from pydm import Display
class MyDisplay(Display):

    def __init__(self, parent=None, args=None, macros=None):
        super(MyDisplay, self).__init__(parent=parent, args=args, macros=macros)

    def file_menu_items(self):
        return {"save": self.save_function, "load": (self.load_function, "Ctrl+L")}

    def menu_items(self):
        return {"Action1": self.action1_function, "submenu": {"Action2": self.action2_function, "Action3": self.action3_function}}

    def save_function(self):
        # do something to save your data

    def load_function(self):
        # do something to load your data

    def action1_function(self):
        # do action 1

    def action2_function(self):
        # do action 2

    def action3_function(self):
        # do action 3
