Hide (or Toggle) Find Results panel with keyboard command

Alan Kilborn

So I have my Find Results panel (and Pythonscript console “grouped” with it) at the bottom of my Notepad++ main window (probably pretty typical?). I can press the X with the mouse on this grouping of panels to close it when I want more screen real estate, and it appears back again automagically when I do my next Find-All or Find-in-Files. Life is good.

However, it would be faster for me to do this closing/hiding (and maybe reopening too) with a keyboard shortcut. Is there one for this functionality, and if not, is it possible to assign one, or otherwise do this?

do you really wanna do this?
Because in order to achieve this you need to send grandpa to bed. ;-)

################################################################################# 
## close find result and/or python script window
import ctypes
from ctypes.wintypes import BOOL, HWND, LPARAM

WNDENUMPROC = ctypes.WINFUNCTYPE(BOOL, HWND,LPARAM)

FindWindow = ctypes.windll.user32.FindWindowW
GetWindowText = ctypes.windll.user32.GetWindowTextW
GetWindowTextLength = ctypes.windll.user32.GetWindowTextLengthW
SendMessage = ctypes.windll.user32.SendMessageW
EnumChildWindows = ctypes.windll.user32.EnumChildWindows
GetClassName = ctypes.windll.user32.GetClassNameW
GetParent = ctypes.windll.user32.GetParent

nppHandle = FindWindow(u'Notepad++', None)
curr_class = ctypes.create_unicode_buffer(256)
WM_CLOSE = 0x010

def foreach_window(hwnd, lParam):
    if curr_class[:GetClassName(hwnd, curr_class, 256)] == u'#32770':
        length = GetWindowTextLength(hwnd)
        if length > 0:
            buff = ctypes.create_unicode_buffer(length + 1)
            GetWindowText(hwnd, buff, length + 1)    
            if buff.value in [u'Python Script', u'Find result']:
                SendMessage(GetParent(GetParent(hwnd)), WM_CLOSE, 0, 0)
                return False
    return True
    
EnumChildWindows(nppHandle, WNDENUMPROC(foreach_window), 0)

F7 for find result window and a shortcut mapped to show python script console
will wake him up again.

One word of (serious) warning, when calling ctypes function make sure you
don’t overwrite it accidentally

I get the joke about grandpa (GetParent() + GetParent()). :-D

But I don’t understand the “serious warning” – can you elaborate?

Looks like another winner of a script, Claudia, as it is working fine! Thank you yet again.

So I notice that the PS console window will get shown again upon a script error (thanks to the functionality from here: https://notepad-plus-plus.org/community/topic/13277/pythonscript-show-console-on-error/). This is nice behavior! :-)

This got me to wondering how to make hitting a simple “print” statement in a script also re-show a currently hidden PS console window…hmmmm…I find that interesting…

Hi Alan,

warning is a bit extreme, maybe I should have said “info”.
As you already use some scripts which uses ctypes you need to take care
that you function definitions like, let’s say

GetWindowText = ctypes.windll.user32.GetWindowTextW

is used consistently because if a script, which you might run after this one, has something like

GetWindowText = ctypes.windll.user32.GetWindowTextA

than it will break this script. So I would recommend that you create a, let’s say, winapi.py file,
put all of this ctypes stuff in it and import it accordingly.

This got me to wondering how to make hitting a simple “print” statement in a script also re-show a currently hidden PS console window…hmmmm…I find that interesting…

Redefining a statement doesn’t work but redirecting the stdout output might be a possible way.
Or maybe try establishing a console.editor callback like charadded. I didn’t try both of them,
just some thoughts.

If you don’t mind changing your print statements into print() function calls, you should be able to adapt the technique shown here: https://stackoverflow.com/questions/550470/overload-print-python

into something like this (put it in startup.py):

from __future__ import print_function
import __builtin__

def print(*args, **kwargs):
    notepad.runPluginCommand('Python Script', 'Show Console') 
    return __builtin__.print(*args, **kwargs)

…could be a bit redundant, running the show-console command, even when already shown…
