Can’t change some menu shortcuts

bahman

I wanted to remove all menu shortcuts but apparently some are not added to the preferences yet. It's not possible to change them using a script either:

('Edit', 'Select All')
('Edit', 'Copy As Component')
('Edit', 'Paste in Layer')
('Python', 'Show Log File')
('Python', 'Jump Back')
('Window', 'Minimize')
('Window', 'New Space Center')
('Window', 'Zoom in A Bit')
('Window', 'Zoom out A Bit')
('Help', 'Application Help')

Sorry for nitpicking, but I need to remove them for a tool that its shortcuts can conflict with them.

I rewrote your code in another way that is more clear to me, maybe others would find this useful. This opens a window in which, the start button initiates the override RF keys state and also there is a stop button:

import AppKit
from vanilla import *

_ignore = {'⌘s', '⇧⌘s', '⌘q', '⇧⌘q'}

MODIFIER_INT_TO_STR = {
				AppKit.NSCommandKeyMask: '⌘',
				AppKit.NSControlKeyMask: '⌃',
				AppKit.NSAlternateKeyMask: '⌥',
				AppKit.NSShiftKeyMask: '⇧',
				AppKit.NSCommandKeyMask | AppKit.NSShiftKeyMask: '⇧⌘',
				AppKit.NSCommandKeyMask | AppKit.NSAlternateKeyMask: '⌘⌥',
				AppKit.NSCommandKeyMask | AppKit.NSControlKeyMask : '⌃⌘',
				AppKit.NSControlKeyMask | AppKit.NSShiftKeyMask: '⇧⌃',
				AppKit.NSAlternateKeyMask | AppKit.NSShiftKeyMask: '⇧⌥',
				}

class KeyEventMonitor(object):

	def __init__(self):
		self.monitor = None
		self.w = Window((300, 90), "KeyEventMonitor Debuggin window")
		self.w.b1 = Button((10, 10, -10, 20), "Stop",
							callback=self.stop)
		self.w.b2 = Button((10, 40, -10, 20), "Start",
							callback=self.start)
		self.w.bind("close", self.stop)
		self.w.open()

	def stop(self, sender):
		self._stopOverridingRFkeys()

	def start(self, sender):
		self._startOverridingRFkeys()

	def _startOverridingRFkeys(self):
		self._stopOverridingRFkeys()
		self.monitor = AppKit.NSEvent.addLocalMonitorForEventsMatchingMask_handler_(
			AppKit.NSKeyDownMask, self._keyDown)

	def _stopOverridingRFkeys(self):
		if self.monitor is not None:
			AppKit.NSEvent.removeMonitor_(self.monitor)
		self.monitor = None

	def _keyDown(self, event):
		allKeys = MODIFIER_TO_STR.get(event.modifierFlags(), '') + event.charactersIgnoringModifiers().lower()
		if allKeys in _ignore:
			print("overriding %s" %allKeys)
		else:
			self._stopOverridingRFkeys()
			AppKit.NSApp().sendEvent_(event)
			self._startOverridingRFkeys()

I didn't think of that! Thank you, Frederik. This is very interesting.

I would advise to take a different route... :)

Prepolator and MetricsMachine extensions have their own shortcuts with an option to overwrite the existing shortcuts. There are just not enough modifiers and keys...

an example:

subscribe when your tool/window becomes active and unsubscribe when it deactivates!

import AppKit

_specialCases = [
    ("w", AppKit.NSCommandKeyMask),  # close window, dont subscribe afterwards
    ("`", AppKit.NSCommandKeyMask),  # jump to next window, dont subscribe afterwards
    ("`", AppKit.NSCommandKeyMask | AppKit.NSShiftKeyMask),  # jump to prev window, don't subscribe afterwards
]

class KeyEventMonitor(object):
    
    def __init__(self):
        self.monitor = None
        
    def subscribe(self):
        self.unsubscribe()
        self.monitor = AppKit.NSEvent.addLocalMonitorForEventsMatchingMask_handler_(AppKit.NSKeyDownMask, self.eventHandler)

    def unsubscribe(self):
        if self.monitor is not None:
            AppKit.NSEvent.removeMonitor_(self.monitor)
        self.monitor = None
    
    def eventHandler(self, event):
        inputKey = event.charactersIgnoringModifiers()
        eventModifiers = event.modifierFlags()
        
        # check if inputKey and eventModifiers match with your shortcuts
        found = True
        if inputKey = "s" and eventModifiers & AppKit.NSCommandKeyMask:
            # overwrite cmd s
            pass
        else:
            found = False

        if not found:
            self.unsubscribe()
            AppKit.NSApp().sendEvent_(event)
            if (inputKey, eventModifiers) not in _specialCases:
                # don't resubscribe when the window is closed
                self.subscribe()
