[Sugar-devel] [PATCH sugar 3/7] Views: Replace the hippo based layout with one using GTK+ containers

Simon Schampijer simon at schampijer.de
Mon Aug 6 06:04:18 EDT 2012


The requirement was to be able to position and size the widgets with
different layouts in the Views. We need to be able to have fixed
positions (e.g. the owner icon and current activity icon) and we need
to be able to change the position (e.g. BuddyIcon in the Neighborhood
View) and move the widget by drag and drop (e.g. RandomLayout).

The implementation uses a gtk.Container (SugarViewContainer) without
an associated GdkWindow to hold the widgets since we do not want to do
drawing in this container. The desired layout and the owner icon and
optional activity icon are passed at initialization time.

A ViewLayout is responsible to calculate the positions and sizes for
the SugarViewContainer. To keep track of the positions it uses a grid
that is initialized on the first allocation. The owner icon
(activity icon) will be added to the grid to make sure it keeps the
fixed position.

The SpreadLayout used in the GroupBox and in the MeshContainer does
add all it's children to the grid in order to use the collision
detection from the grid to not place icons over each other.

The RandomLayout does place all it's children in the grid as well
for collision detection purposes.

This patch is based on the work from Walter Bender,
Daniel Drake and Raul Gutierrez Segales.
