Bug Description

I'm trying to write some tests for evince or gedit for evalutating autopilot with GTK. I currently find it really hard to test the expected state as the widget tree is not very easy to traverse (see also bug 1082388 and bug 1082385).

The objects on the application widget tree should have proper identifiers that are given to them in the GtkBuilder .ui files. These identifiers are the ones that the actual program code uses to refer to them, so they are both stable, and also the most appropriate means to identify a particular widget.

I know that GTK currently does not seem to expose the GtkBuilder IDs to the widgets, so we might need to fix that (and add a GTK+ task). It might be possible to access them at the C level though, in the autobuilder GTK module?

This sounds like an issue in autopilot-gtk to me. I've assigned Allan Lesage to look into this - hopefully between the three of us we can work this out.

Right, let's say I'll ask you on this bug or on IRC once I (or someone else) finds time to work on this. Thanks!

This is still one of the most important issues in my opinion. I'll try and see if this can be done entirely within ap-gtk, or whether it actually needs a GTK patch.

So, the existing "name" property, which is usually empty, actually comes from GtkWidget and is a custom name that the code can set with gtk_widget_set_name(), or a GtkBuilder file can set with "name", which can be referred to with CSS stylesheets, etc. So we should let this alone.

The name that I'm interested in is the GtkBuilder ID, which is unique and usually doesn't change in a project as code uses this to actually deal with the widgets (gtk_builder_get_object() ). So what we want to do is to use gtk_buildable_get_name() to get the GtkBuilder ID and export that to a property like "builder_name". I already verified that this gives the expected names, one can call Gtk.Buildable.get_name(obj) in GI.

summary: - Needs proper widget identifiers
+ Expose GtkBuilder widget identifiers

It turned out to be surprisingly simple. The hardest part is to pick a name for it, but the existing convention (globalRect, Children) seems to be to use identifiers with capital names as these don't occur as "real" GtkWidget GObject properties. So I picked BuilderName for now, but I'm open to changing this.

Not a branch for now, as this adds new tests, and this depends on https://code.launchpad.net/~pitti/autopilot-gtk/add-tests/+merge/171036 (which is in turn blocked by https://code.launchpad.net/~pitti/autopilot-gtk/testsuite/+merge/170607). To avoid having to do excessive branch surgery, I keep this as a patch for now.
