Gnome: Allow double click on title bar to maximize the window

[jankatins]

Is your feature request related to a problem? Please describe.

I'm used to double clicking the title bar of a gnome app (and also a mac one, but right now I'm an a GNOME laptop) to maximize a window. wezterm doesn't allow me that.

I think I remember not having that problem a while ago?

My gnome is configured to do this:

λ  gsettings get org.gnome.desktop.wm.preferences action-double-click-titlebar
'toggle-maximize'

Describe the solution you'd like

I would like to have a double click in the title bar maximize the wezterm window.

Describe alternatives you've considered

I could click the maximize button, but it's a much smaller target than the whole title bar. I can also use a custom key combo (WIN+UP in my case)

Can you share more about the environment in which you are running?

If you are running in wayland mode with a compositor that doesn't support server side decorations (eg: Mutter doesn't), then you are out of luck. This kind of titlebar action is handled by the window manager/compositor. For Wayland with client-side decorations, there is no standard protocol for sharing this kind of window environment policy with the application, unless the application is a GTK program and happens to cheat and encode all the same logic on the client side.

I recommend enable_wayland=false to cause wezterm to run under XWayland instead, which will effectively enable server side decorations and should make this work again.

Gnome reports that it is running Wayland and I run whatever debian gives me when I install gnome. So I'm probably out of luck, I guess?

λ  wmctrl -m

I noticed that Chrome also is a bit sluggish: if my perception is not misleading me, I have to tripple click... gitkraken (an electron app) works on double click. No idea if that is actually running in a gtk window under the hood?

That's not cheating, that's kinda what you're supposed to do. Alacritty does implement that for example.

With the configuration enable_wayland=false the redrawing in resize window is slow.
