Error when applying mica

[sumeshir26]

Hi! Reallay awsome project!
I get this error when running on tkinter window:
Code:
ApplyMica(HWND=windll.user32.GetParent(app.winfo_id()), ColorMode=True)
Error:

  File "D:\Coding\TimerX\main.py", line 783, in makeWindowsBlur
    ApplyMica(HWND=windll.user32.GetParent(app.winfo_id()), ColorMode=True)
  File "C:\Users\suchi\AppData\Local\Programs\Python\Python310\lib\site-packages\win32mica\__init__.py", line 54, in ApplyMica        
    SetWindowCompositionAttribute(HWND, Wca)
ctypes.ArgumentError: argument 2: <class 'TypeError'>: expected WINDOWCOMPOSITIONATTRIBDATA instance instead of WindowCompositionAttribute

Can't you get the hwnd of the window using the .frame() function?

Becayer you need to apply this on each window, and not in the app itself

[marticliment]

*Because

Aditionally, Are you using any kind of library like PythonBlurBehind?

[sumeshir26]

I used to use PythonBlurBehind, but now removed it. The app's background is transparent for PythonBlurBehind. Should I make it solid again?

When using .frame, same error

[marticliment]

The issue is because of ctypes interferences. My soolution was to use a moded version of it. You only have to remove the declarations of the rgument datatypes.

SetWindowCompositionAttribute.argtypes = (HWND, WINDOWCOMPOSITIONATTRIBDATA)
SetWindowCompositionAttribute.restype = ctypes.c_int

I also faced the same issue, and finished by modding the module

[sumeshir26]

So I need to mod ctypes? I cant find matching lines in this code

[marticliment]

No need to mod ctypes but the pythonBlurBehind module

Although it may not be used, when the moduleis imported it interfiers with win32mica because of those two lines in the PythonBlurBehind Module. Commend them (the module will still work) and everyuthing should go fine

This is an exapmle taken from ElevenClock

That fixed it! But is there any way to remove the black box on the title or disable ExpandFrameIntoClientArea until the titlebar text is fixed on Beta Channel?

[marticliment]

I don't think so. My approach was to literally set an empty string as titlebar and an empty icon on window icon. With this set it does look good

Thank you for your help!
