Window position uses inconsistent coordinate units on Windows with display scaling

[alemariani]

python: 3.13
pywebview: 6.1
platform: Windows 11

I noticed an inconsistency when setting and reading the window position on Windows with display scaling enabled.

• When setting the window position, the display scale factor appears to be taken into account.
• When reading the window position, the returned coordinates appear to be in physical pixels.

This makes the reported window coordinates inconsistent and difficult to use reliably.

Steps to reproduce:

1. Use the example from: https://pywebview.flowrl.com/examples/move_window.html
2. Add an extra print statement to log new_x and new_y.
3. Run the example on a Windows 11 system with display scaling enabled.

This is the output I get:

Window coordinates are (375, 375)
Window dimensions are (996x738)
Primary screen: 2560x1440
new_x, new_y: (1464, 602)
Window coordinates are now (1830, 752)

This is my display setting

I pushed a fix to master.

Tested and the log is now coherent:

Window coordinates are (300, 300)
Window dimensions are (996x738)
Primary screen: 1920x1080
Moving window to (824, 242)...
Window coordinates are now (824, 241)

However the example should move the window close to the right-bottom corner of the screen, but the window goes partially off screen.
It looks related to the window size management.

I gave a try to the resize example (https://github.com/r0x0r/pywebview/blob/master/examples/resize.py).
The window is created with size 800x600 but then is read scaled to 996x738.
resize method instead looks working correctly.

this is the output I get:

Window size is (996, 738)
Window size is (420, 420)

Logical / physical pixel handling in Winforms was a mess, but the whole thing is revamped now. Now it uses and reports exclusively logical pixels. Screen object reports logical pixels, but there are now additional properties for physical pixels, scale and dpi.

Now everything looks good! thank you!

Actually, I still found some issue. The "scale" is not retrieved correctly.

Now these examples work well:

• https://pywebview.flowrl.com/examples/move_window.html
• https://github.com/r0x0r/pywebview/blob/master/examples/resize.py

This instead no:

• https://github.com/r0x0r/pywebview/blob/master/examples/screens.py

this is what I get

Screen 1:
  Position: (-1920, 164)
  Size: 1920x1080
  Scale: 1.0x
  DPI: 96
  Physical Size: 1920x1080

Screen 2:
  Position: (0, 0)
  Size: 2048x1152
  Scale: 1.0x
  DPI: 96
  Physical Size: 2048x1152

Screen 1 is right, while Screen 2 should have a
scale: 1.25
Physical Size: 2560x1440

Alright, fixed that one on master. I will make a new release soonish
