[Sugar-devel] Layout with gtk3

[Manuel Quiñones]

Hi,

sorry for not joining the discussion yet.  I'm a bit overloaded with
non-Sugar stuff.

I remember Agustín Zubiaga also mentioned Box(orientation) instead of
HBox, VBox at the time of the GTK3 port, and then I came to read about
Grid. When I checked, the GTK docs were recommending it, but most of
their code was not using it, and the API looked weird to me in Python,
less readable.  That is for a replacement of simple, flat boxes.  But
if Grid allows to remove the boxes nesting in Sugar widgets like
Palette, then we definetely should use it.

For the widget spacings and dimentions, keep in mind that part is done
in the Python code, and part in the artwork CSS. And some things can
be done in the two sides.

Example:

grid margin (Python):
https://developer.gnome.org/gtk3/stable/GtkWidget.html#GtkWidget--margin
margin (CSS) https://developer.gnome.org/gtk3/stable/GtkStyleContext.html#GTK-STYLE-PROPERTY-MARGIN:CAPS
separator height (CSS):
https://developer.gnome.org/gtk3/stable/GtkWidget.html#GtkWidget--s-separator-height

What I've been doing in styling is: use CSS as much as possible.  If
there is a CSS way and also a programmatic way, use CSS.

To check graphics regressions is good to do visual comparisons for example:
