Re: [PATCH] gtk: Add show_tabs=on|off command line option.

[Hanna Reitz]

Hi,

(Thanks for the patch!)
On 27.06.22 18:44, Felix xq Queißner wrote:
The patch adds "show_tabs" command line option for GTK ui similar to 
"grab_on_hover". This option allows tabbed view mode to not have to be enabled by hand at 
each start of the VM.

I’m not sure we have a hard rule on it, but I think generally commit 
messages should be wrapped at 72 characters.

I don’t really understand what “tab items” is supposed to mean. Perhaps 
“tabs item”?

But a bit more verbosity might be nice, too.  What about “Display the 
tab bar for switching between the various graphical interfaces (e.g. VGA 
and virtual console character devices) by default”?  (Note the 
imperative on “Display”, I think we generally use the imperative to 
document options.)

There is some documentation further below that explains the other 
options.  I think this new option should be explained there as well.  
(Probably reusing the documentation from qapi/ui.json.)

Not that I’d know any of this code, but FWIW, makes sense and looks good 
to me.

Thanks!
