Finding available shortcut keys (originally "Where's the 'New Window' command?")

Yes, it is larger than a “prompt” solution, and the TaskDialog is strictly defined by MS. You can only have what it provides.

If you want a custom dialog, you have to wrap DialogBoxes
but that is just as heavy, if not heavier, than the TaskDialog.

The prompt solution may be fine for simple scripts, but as soon as you need to parameterize a script with different settings depending on different models, it is much easier to use a guided dialog, at least in my opinion.

“Simple” scripts are really all we should be doing, with a tool such as the PythonScript plugin.

Of course, and probably more of late, some of mine haven’t exactly been “simple”, so I’m a violator of my above edict. :-)

And maybe sadly, I’ve got a doozy in the in-progress pipeline. Maybe my excuse for it is, let’s push the limits of a PS.

But maybe my overall point is, if I can keep the UI relatively simple-minded, I can spend more time on the “meat” of whatever the script is trying to accomplish.

Others can go off and make the UI part as polished (and as complicated and lengthy) as they want to, in their own scripts.

:-D for sure !! :-D

As for sys.exit, I found out that calling a “main” function and returning from that function serve the same purpose.

Due to the scope errors I’ve been getting, I decided to forego that, and just put everything as immediate commands.

@Alan-Kilborn said in Finding available shortcut keys (originally “Where’s the ‘New Window’ command?”):

I’m sure it works great.
IMO though, it seems “heavy”.

At 445 lines for do-nothing sample code, “heavy” seems an understatement. 😁

@TBugReporter said in Finding available shortcut keys (originally “Where’s the ‘New Window’ command?”):

How can I prematurely end my script (if something weird happens)?

Here’s what I came up with for this:

def bailout(msg):                               # routine to display error message and exit
    print(msg)                                  # duplicate msg to console
    notepad.messageBox(msg, "Error", 0)
    user32.keybd_event(VK_MENU,   0, 0,     0)  # press alt key
    user32.keybd_event(VK_P,      0, 0,     0)  # press P key (to activate "Plugins" menu)
    user32.keybd_event(VK_P,      0, KEYUP, 0)  # release P key
    user32.keybd_event(VK_MENU,   0, KEYUP, 0)  # release alt key
    user32.keybd_event(VK_P,      0, 0,     0)  # press P key (to activate "Python Script" submenu)
    # above assumes no other Plugins starting with "P" are installed
    user32.keybd_event(VK_P,      0, KEYUP, 0)  # release P key
    user32.keybd_event(VK_RIGHT,  0, 0,     0)  # press cursor right key (to enter submenu)
    user32.keybd_event(VK_RIGHT,  0, KEYUP, 0)  # release cursor right key
    user32.keybd_event(VK_DOWN,   0, 0,     0)  # press cursor down key
    user32.keybd_event(VK_DOWN,   0, KEYUP, 0)  # release cursor down key
    user32.keybd_event(VK_DOWN,   0, 0,     0)  # press cursor down key again (to move to "Stop Script")
    user32.keybd_event(VK_DOWN,   0, KEYUP, 0)  # release cursor down key
    user32.keybd_event(VK_RETURN, 0, 0,     0)  # press enter key
    user32.keybd_event(VK_RETURN, 0, KEYUP, 0)  # release enter key

… or you could have used

notepad.runPluginCommand('Python Script', 'Stop Script')

(When the only tools you know about are hammers, all your problems tend to look like nails.)

And now, question number umpteen-plus-one, regarding this part of your script:

    sk_mapper_hwnd = user32.FindWindowW(None, u'Shortcut mapper')
    if not sk_mapper_hwnd:
        print('Shortcut mapper was not found')
        return

    sys_tab_hwnd = user32.FindWindowExW(sk_mapper_hwnd, None, u'SysTabControl32', None)
    if not sys_tab_hwnd:
        print('SysTabControl32 was not found')
        return

    item_count = user32.SendMessageW(sys_tab_hwnd, TCM_GETITEMCOUNT, 0, 0)
    if not item_count:
        print('TCM_GETITEMCOUNT returned 0')
        return

    babygrid = user32.FindWindowExW(sk_mapper_hwnd, None, u'BABYGRID', None)
    if not babygrid:
        print('BABYGRID was not found')
        return

I’d like to add “Abort, Retry, Ignore?” dialogs to these, but I’m getting tripped up on the “Retry” part. What would you consider to be the best practice for this?

Ekopalypse

@TBugReporter

something like this

while True:
    result = notepad.messageBox('','', MESSAGEBOXFLAGS.ABORTRETRYIGNORE)
    if result != MESSAGEBOXFLAGS.RESULTRETRY:
        break

Alan Kilborn

It boggles the mind that someone would ever think to use the Stop Script menu item, in code, to “bail out”. Just write code that nicely returns, like @Ekopalypse 's main example from earlier. Stop Script should only be run from the menus as a last resort, a “kill my script” kind of thing. And I don’t think I’ve ever had a need to use it.

while True:
    result = notepad.messageBox('','', MESSAGEBOXFLAGS.ABORTRETRYIGNORE)
    if result != MESSAGEBOXFLAGS.RESULTRETRY:
        break

Okay, but where do I put the code that I want it to retry, and where do I put the code that tests whether to show the MessageBox? (without having to duplicate either of those?)

Yeah, but isn’t it nice to know that your mind can still be boggled? 😁

This was a stopgap measure for me - a placeholder until I could understand my difficulties with scope for variables. I think I got that under control; I just need to test it out and then I’ll do like you said.

or alternately, if it makes more sense to you,

while True:
    result = notepad.messageBox('','', MESSAGEBOXFLAGS.ABORTRETRYIGNORE)
    if result == MESSAGEBOXFLAGS.RESULTRETRY:
        # code to redo goes here
    else:
        break
    # code to redo goes here

@PeterJones

It seems to me that that structure won’t do the “code to redo” a first time without first putting up the A/R/I box…?

PeterJones

@TBugReporter ,

It seems to me that that structure won’t do the “code to redo” a first time without first putting up the A/R/I box…?

Then put the code in whatever order you think is logical for your needs.

while True:
   # code to do every loop goes here 
   result = notepad.messageBox('','', MESSAGEBOXFLAGS.ABORTRETRYIGNORE)
   if result != MESSAGEBOXFLAGS.RESULTRETRY:
        break

I’ve now tried this …

def bailout(msg):
    print(msg)
    user_response = notepad.messageBox(msg, "Error", MB_CANCELTRYCONTINUE | MB_ICONWARNING)
    if user_response == MB_RESULTCANCEL:
        notepad.runPluginCommand('Python Script', 'Stop Script')
    else:
        return user_response

def main():
    # ...
    while True:
        sk_mapper_hwnd = user32.FindWindowW(None, u"Shortcut mapper")
        if not sk_mapper_hwnd:
            action_to_take = bailout("Mapper window not found!")
        if action_to_take != MB_RESULTTRYAGAIN:
            break
    # ...

… but that gives me …

UnboundLocalError: local variable 'action_to_take' referenced before assignment

Where did I go wrong?

Ekopalypse

@TBugReporter

Scope problem. An if-block introduces a new scope and the variables defined there are only valid within this scope. Either the comparison with MB_RESULTTRYAGAIN is indented to have it in the same scope, or action_to_take must be defined at the same scoping level as the comparison.

I don’t know that I like the trend of this thread. It seems we’re teaching Python??

This discussion has stopped being about “new window” or about “shortcut keys”, and really ceased even being about Notepad++. And now it’s even attracting random posts as well.

This topic is being locked. If anyone has Noteapd++ related discussion, a new topic can be started quite easily; if you need to, provide a link back to this discussion for reference.
