[maemo-developers] Problems with larger buttons in HButtonBox

[From: Markku Vire]

Hi,

In Maemo environment the buttons inside GtkHButtonBox have special style
attached to them. You can search the following kind of line from
gtkrc:

  widget_class "*.GtkHButtonBox.GtkButton" style "osso-dialogbutton"

All these buttons have this kind of border defined:

  border   = { 20, 20, 0, 0 }

This means that in vertical direction there is no "upper part" or
"lower part" defined, just the center piece. For horizontal
direction there is 20px of "left side" and "right side".

The sapwood theme engine does "filling the middle" by tiling
the images, so you'll end up having the button tiled in
vertical direction and good-looking in horizontal direction.

If you want to try, you can replace the zeroes by small integers,
remove/regenerate gtkrc caches and reboot... After these steps
the buttons should look better. Anyway, the same effect will show
up if you install your app to some other device.
