glibmm | object | Ver: unspecified
Summary: Allow dynamic module type registration
(g_type_module_register_type)
Product: glibmm
Version: unspecified
Platform: Other
OS/Version: Linux
Status: NEW
Severity: normal
Priority: Normal
Component: object
AssignedTo: gtkmm-forge@...
ReportedBy: murrayc@...
QAContact: gtkmm-forge@...
GNOME version: Unspecified
GNOME milestone: Unspecified

We need to allow classes to use
g_type_module_register_type():

http://library.gnome.org/devel/gobject/unstable/GTypeModule.html#g-type-module-register-type
instead of g_type_register_static(), currently used in
Glib::Class::register_derived_type(), called from the derived
SomeWidget_Class::init() functions.

The custom type-registration function would then be called by a plugin entry
point, such as the entry point,
void hd_plugin_module_load(HDPluginModule* plugin);
for a Hildon Desktop Widget.

Maybe we could add an optional
_DYNAMIC_REGISTRATION()
gmmproc macro that would _add_ a
SomeWidget::register_dynamic_type(GTypeModule* module)
that could be called from the entry point function,
and we could check for that previous registration in our regular
SomeWidget_Class::init() functions to avoid a second (static) type
registration.

glibmm_dynamic_gype.patch

An untested patch to implement this:

2009-06-19 Murray Cumming <murrayc@...>

Allow dynamic GType registration, using g_type_module_register_type().

* glib/glibmm/class.[h|cc]: Added a register_derived_type() overload
that
takes an extra GTypeModule* parameter, and which calls
g_type_module_register_type() instead of g_type_register_static().
* tools/m4/class_gobject.m4:
* tools/m4/class_gtkobject.m4:
* tools/m4/class_shared.m4: Added a _DYNAMIC_GTYPE_REGISTRATION macro
to
be used in the class in the hg file, to add a
*_Class::init(GTypeModule)
method, and a get_type(GTypeModule*) method that calls it.

TreePath::empty() does return false if the gobject_ is NULL. It should return
true, because it is invalid.

I can provide a patch if you want.

Gtk::TreeView::row_activated() require a TreeViewColumn. But
TreeView::get_path_at_pos() can return a NULL TreeViewColumn*. So we need an
overload that either just accept a TreeViewColumn* or one that does not
require the parameter.

I can provide a patch if you want.
