Layout changes on a different screen resolution problem

[redoine32]

Hi Devs!
Iam very new to coding and i have a problem with my UI layout changes on defrent screen sizes even when i change the resolution of my screen here is my code i hope some one can help me with this Problem thanks in advance

here is the problem that i have the widget doesn’t fit on the screen when viewing it on a smaller screen resolution

it should be like this on every screen resolution

[Akascape]

Try this method:

customtkinter.deactivate_automatic_dpi_awareness()

[Akascape]

@redoine32 Ok, try these methods as well;

import ctypes
ctypes.windll.shcore.SetProcessDpiAwareness(0)

and

customtkinter.set_widget_scaling(1.0)
customtkinter.set_window_scaling(1.0)
customtkinter.deactivate_automatic_dpi_awareness()

[redoine32]

import ctypes
ctypes.windll.shcore.SetProcessDpiAwareness(0)

still the same Problem @Akascape

[Akascape]

@redoine32 Try to properly use rowconfigure and columnconfigure weights in grid layout.

[redoine32]

@redoine32 Try to properly use rowconfigure and columnconfigure weights in grid layout.

@Akascape what do you suggest cause iam very new to coding

[Schkimansky]

Redoine theres another way to do this, Although its cumbersome to use so i wouldnt recommend it unless you cant find a method that works.

Instead of doing width=200, Do width=inches(0.2). Using inches instead of pixels makes it immune to any resolution, any sizing changes or whatsoever.

Heres the implementation for the inches function:

root = ctk.CTk()

DPI = root.winfo_fpixels('1i')

def inches(in):
    return in * DPI
    
ctk.CTkButton(root, width=inches(1)) # Makes a button with the Width of 1 inch

Change anything that using pixels to inches IF it changes during resolution changes.
Note that i really dont recommend this and you should only use this if you cant find any other way since this is not properly compatible with ctk/tk grids.
