Connect to the model's "position" signal. (e_text_init): Set default value

2001-01-29  Jon Trowbridge  <trow@gnu.org>

	* gal/e-text/e-text.c (e_text_init): Connect to the model's
	"position" signal.
	(e_text_init): Set default value for rgba_object as blue.
	(e_text_destroy): Disconnect model position signal.
	(fix_selection): Some extra sanity checking to keep the selection
	from spilling outside of the bounds of the text string as it
	expands or contracts.  Should be obsolete due to the changes to
	objectify_uris --- but I'll leave this in here for now, in an
	attempt to avoid non-\0-terminated strings, segfaults, and all of
	that fun stuff.
	(e_text_text_model_position): Move our cursor according to the
	suggestions made by our ETextModel, via the "position" signal.
	(text_width_with_objects): Check that text is not NULL.
	(text_draw_with_objects): Accept an extra GdkGC for use in drawing
	objects.
	(e_text_set_arg): Properly handle the "position" signal when
	changing models.
	(e_text_draw): Initialize the GC for drawing objects, if
	necessary.
	(_insert): Comment out the code that adjustes text->selection_*.
	The cursor is now moved by the ETextModel directly via the
	position signal, not by the view.

	* gal/e-text/e-text-model-uri.c (objectify_uris): Add more
	sophisticated uri recognition via regular expressions.
	(objectify_uris): Changed to track position changes as model->text
	expands and contracts along with the objects.  Block the
	objectification of any chunks of text that straddle our current
	position.
	(e_text_model_uri_set_text): Added position info to objectify_uris
	call.
	(e_text_model_uri_insert): Added position info to objectify_uris
	call.
	(e_text_model_uri_insert_length): Added position info to
	objectify_uris call.
	(e_text_model_uri_delete): Added position info to objectify_uris
	call.

	* gal/e-text/e-text-model.c (e_text_model_class_init): Added a
	"position" signal that allows the ETextModel to send cursor
	positioning information back to any view.  We need this for text
	with objects, where the text string can grow and shrink in ways
	that the view doesn't expect.
	(e_text_model_real_insert): Added sanity checking of args and a
	position emission.
	(e_text_model_real_insert_length): Added sanity checking of args
	and a position emission.
	(e_text_model_real_delete): Added sanity checking of args.
	(e_text_model_suggest_position): A wrapper around the "position"
	signal emitter.
