Emit a hover-url signal when the user mouses over a URL, ...

2004-01-04  ERDI Gergo  <cactus@cactus.rulez.org>

	* em-folder-view.c (emfv_on_url_cb): Emit a hover-url signal when
	the user mouses over a URL, ...
	(emfv_hover_url_impl): ... and use BonoboUI to change the status
	bar message...
	(em_folder_view_set_statusbar): ... unless we are asked not to, ...

	* mail-component.c (impl_createControls): ... like in the case of
	the mail component, ...
	(view_hover_url_cb): ... that uses the ActivityHandler to do the
	same

	Add these together, and #127536 is neatly solved.

2004-01-05  ERDI Gergo  <cactus@cactus.rulez.org>

	* e-task-bar.c (init): Create a separate label to the left of the
	progress messages...
	(e_task_bar_message): ...and allow components to set it...

	* e-activity-handler.c (e_activity_handler_message): ...through
	this new ActivityHandler method
