'BadAlloc (insufficient resources for operation)' error on XFCE window manager using PyGPSClient 1.6.0

[uilzzw]

Hi @uilzzw

Sorry you're having difficulties.

I'm not seeing this behaviour on any of the Debian or Fedora Linux platforms I normally use for testing - this may be specific to your GUI management environment - though it should be simple to resolve.

Occasionally the main window may extend beyond the current screen dimensions if you add additional widgets to an existing row, but it's generally just a matter of resizing or maximising the window to fit.

Can you provide a little more information, as per the requested Issue Template?

1. Can you confirm that by 'latest release' you mean v1.6.0?
2. Can you confirm your full tkinter version?

   from tkinter import Tcl
   print(Tcl().call("info", "patchlevel"))

3. When you say the window 'keeps expanding', do you mean of its own accord, without any user intervention?
4. Can you provide the FULL TRACEBACK for the 'crash', if possible?
5. Have you tried reverting to the previous version (1.5.23) and, if so, do you still see the issue?
6. Have you actually tried making the change you describe to main.py and, if so, does that definitely resolve the problem?
7. What native screen resolution are you using?

FYI I have a provisional branch for the next release v1.6.1 which includes the ability to save an initial screen geometry (root.geometry(f"{w}x{h}+{x}+{y}") the json config file. That may resolve your issue, but ideally I'd like to see a full error Traceback first.

Anyone else seeing this?

Thanks

Sorry, I just saw this message today. The following is the situation I encountered.
1.yes

./pygpsclient -V    
pygpsclient 1.6.0

2.tkinter version is 8.6.16

print(Tcl().call("info", "patchlevel"))
8.6.16

3.yes,without any user intervention
4.I cloned the source code and declared an initial window size to tk，Then it will not expand automatically
5. I did not use the previous version. I found that the window would expand from small to large until it crashed. Then I cloned a copy of the source code and declared an initial value for tk.
6.yes，I modified the source code to the following

    root = Tk()
    root.geometry("1800x800") 
    App(root, **kwargs)
    root.mainloop()
    sys.exit()

7. The resolution of my laptop is 1920x1080, and the resolution of the external monitor is 1920x1080.
8. My environment is archlinux+lightdm+xfce4, python venv is 3.11

Thanks

I am able to reproduce your issue using pygpsclient==1.6.0, but only on xfce - it appears to work fine with other Arch window managers (e.g. Gnome and Deepin). On xfce the main window expands until the system eventually runs out of pixel memory:

Try installing v1.6.1. This now sets an initial value for the screen geometry at 75% of full screen resolution (it does it in app.py rather than main.py). It also saves the current window geometry to the json config file and restores this on next restart.

I don't 'hard code' the initial screen geometry to a fixed value because different users have different screen configurations. PyGPSClient is designed to work with 'screens' (including VNC remote desktops) as small as 640x480.

It's not a definitive test, but I span up an Arch Linux + lightdm + xfce4 environment in VirtualBox and ran PyGPSClient 1.6.1 - it appears to work fine (I note the font scaling on the banner panel is a bit high but I think that's an XFCE artefact):

[semuadmin]

For yuks I span up another Arch Linux VM running Gnome (rather than xfce) at 1920x1080, and it all appears to work perfectly, with PyGPSClient versions 1.6.0 and 1.6.1:

I'll do further testing on xfce to see if there are any other gotchas, but for now I think updating to 1.6.1 should resolve the immediate issue.

But I'm inclined to recommend using a different window manager if possible - there are plenty of others to choose from!
