Expected Behaviour

What were you trying to do? Please explain the problem.

I want to resize the window, but the coordinates of the upper left corner remain the same, so I add the "direction SouthEast" parameter after the resize command.

Current resize direction SouthEast w+100p w+100p

Actual Behaviour

The window resize w+100p w+100p. However, the window extends from the center to the four sides , and the coordinates of the upper left corner is changed.

Hi @wenpengy

In testing this using xterm, your command is working how I would expect it to -- as in, the NW corner of the window remains where it is, and the window grows in a SE direction.

For the window you're using, can you run the command xprop on it, and send me the output? I'm specifically interested to know if the WM_NORMAL_HINTS(WM_SIZE_HINTS) XAtom contains a window gravity property.

For this specific window, it might be worth you looking at the Style options of::

To see if that changes anything for you,

Thank you!

Following your tips, I tested other program windows and they worked fine. The window program that doesn't work is kitty. Here is the xprop output of kitty: WM_NORMAL_HINTS(WM_SIZE_HINTS): window gravity: Static.

I tested style options of UseGravity and IgnoreGravity. However, the window still extends from the center to the four sides. The bug should be caused by the kitty program itself.

Thanks again.

Right. With Static gravity, fvwm is doing exactly what it can. This is not a fvwm bug.
