[Gerbv-devel] RFC: fix default screen size on multiple monitor settings - test GTK3 missing.

[Clemens Koller]

Hello!

I was always wondering why gerbv starts by default with a good width (1500pix) but very limited height (450pix) window on my dual-monitor desktop (2x 2048 x 1152, horizontally aligned).

After some digging, I found that some multi monitor detection code does some odd math, messing up if nmonitors >1 aligned horizontally, touching the height as well.
Attached patch might fix that for the assumption that monitors are usually placed next to each other and not stacked on top of each other.
This is off course just an improvisational fix.

It seems that the GTK3 code would be a better solution, but I couldn't verify that code yet. Is there an configure option to build against GTK 3+?

Please comment if the patch is basically ok and how to test gerbv against GTK3.


Regards,

Clemens

Maybe we should just save/restore (via GtkSettings?) last used gerbv
window screen position and size?

GTK3 support require some patching (it was done couple of years ago by
someone and I think I do have those patches), and as GTK3 is not yet
in gschem nor in pcb, and than was no stable GTK3 port for Win, so
gerbv is on GTK2.

My GTK knowledge is very limited. I am not sure if GtkSettings is useful here to save/restore settings.

However having settings stored in ~/.config/gerbv/gerbv.conf definitely makes sense and the capability to choose config files -c, --config <filename> would increase productivity to work with different projects, IMO.

I.e. the configure switch and the new command line switch -u, --units would not be necessary anymore.

Sorry, it is GSettings

Should we really add one more configuration file? We can add units
field in project file, and we can support loading multiply project
files to override some settings.

Looks like it is it:

gsettings list-recursively org.gnome.gthumb

org.gnome.gthumb.browser browser-sidebar-width 285
org.gnome.gthumb.browser window-height 0
org.gnome.gthumb.browser window-width 0
