Tkinter guide?

[pythonprogrammer1101935]

Hi! I saw you wanted to resize the tkinter gui window to full screen so I came here to help.
It's very simple, it only takes one line!
First you need to see how wide and tall your computer is. Ex: 1000x900
Then you put it into a function, here is the code.
Let's use the example I just said(1000x900)
The code would be: win.geometry("1000x900")
Hope this helps! If you need more understanding on tkinter or you would like more help on anything, contact me! Have a good day

That is not a good way to make a full screen window. A better way is to use .attribute()

window.attributes('-fullscreen',True)

Or if you want to use geometry, use "winfo_screenwidth" and "winfo_screenheight" to get the screen dimensions.

width= window.winfo_screenwidth() 
height= window.winfo_screenheight()
window.geometry(f'{width}x{height}')

The problem with hardcoding a number is it will not work on different resolution monitors.

you can get current screen info for all monitors
you must install screeninfo if not already installed: pip install screeninfo
then run:

import screeninfo


for n, monitor in enumerate(screeninfo.get_monitors()):
    print(monitor)
    print(f"\nMonitor {n}:")
    print(f"    width pixels: {monitor.width}")
    print(f"    height pixels: {monitor.height}")
    print(f"    width mm: {monitor.width_mm}")
    print(f"    height mm: {monitor.height_mm}")
    print(f"    monitor name: {monitor.name}")

Typical output

Output:
Monitor 0:
    width pixels: 1920
    height pixels: 1080
    width mm: 598
    height mm: 336
    monitor name: DVI-I-1

Then what would be the point of using it as a function?

Not sure what you are responding to. If it is my post about why you can't make a window full screen by setting geometry, the reason why is hard coding numbers like 1000x900 only make the window full screen if the display size is 1000x900. If your display is smaller, part of the window will be hidden. If the display is larger, the window will not fill the screen.

.geometry() will work, but you should ask Python for the screen dimensions if you want your window to fill the screen regardless of what computer you are using.

[Larz60+]

you can get the screen size by using the method I show in post # 13.
Then use that in your geometry statement which is safe to use, as it code will adjust for the display being used.

if you still want to know how to open a window in full screen:

wm.attributes("-fullscreen",1)
