#7 --geometry command line control is broken

[Hamish B]

The --geometry switch doesn't work properly.

$ gpsdrive -M pda --geometry=320x240 &
$ xwininfo | grep -A1 'Width:'
Width: 610
Height: 659

$ gpsdrive -M pda --geometry=800x600 &
$ xwininfo | grep -A1 'Width:'
Width: 1090
Height: 1019

$ gpsdrive -M car --geometry=800x600 &
$ xwininfo | grep -A1 'Width:'
Width: 1280
Height: 1024
(actual screen dimentions)

$ gpsdrive --geometry=640x480 &
$ xwininfo | grep -A1 'Width:'
Width: 1366
Height: 1071

Yes with defaults it fits as fullscreen-but-windowed for me in car mode.

But --geometry should override that default.

That covers the --geometry=320x240 case, but why then are 800x600 and 640x480 both bigger than 1000x1000?

ok, I'll have a look inside the debugger and see if I can figure out
why it is going funny on my machine.

One thing I find is that the space around the dashboard numbers is a bit
too large. Perhaps that just depends on the font size you use, my
font_bigtext is 26 (Sans bold) and there is still about 1cm around all
edges.

Hi, I just added a gtk_window_get_size() + printf() call to gui.c.

starting gpsdrive with: gpsdrive --geometry=640x480
gtk_window_get_size() debug msg (and xwininfo) returns:
xsize=1499 ysize=1224 geometry=[640x480]

I see in the help that the parsing should happen after gtk_widget_show_all(), but then in the code example it is not. ???

http://library.gnome.org/devel/gtk/stable/GtkWindow.html#gtk-window-parse-geometry

something weird WRT the order of calls I guess..
