Added; a new test program that demonstrates objects in ETexts.
2001-01-26 Jon Trowbridge <trow@gnu.org> * gal/e-text/e-text-model-test.c: Added; a new test program that demonstrates objects in ETexts. * gal/e-text/e-text-model-uri.c: Added; a text model that converts URIs in the text into objects that are passed off to the GNOME URI handler when activated. This is actually still extremely broken; I got it just working enough to test out my EText changes. * gal/e-text/e-text.c: A whole lot of changes, designed to make ETextModel objects render properly. The basic idea of the changes is pretty simple, though. (text_width_with_objects): First of all, this function is an alternative to e_font_utf8_text_width that takes into the account the embedded \1s in the text string and properly accounts for the width of the object strings. (unicode_strlen_with_objects): Next, this function finds the proper strlen of a string, expanding the \1s. (text_draw_with_objects): Finally, this is just a replacement for e_font_draw_utf8_text that does the right thing for objects. I've gone through all of e-text.c and replace calls by those original functions with my new object-enabled alternatives. (split_into_lines): Some tweaking to get line breaking to work properly. Made \1 into a "break character", so that we can break lines between multiple adjacent objects. (Which seemed like the right thing to do, but there may be cases where that is undesireable.) (_get_position_from_xy): Fixed to properly handle embedded objects, and to get the right selection semantics for objects. (Or at least semantics that feel right to me.) Also fixed a bug that caused selection, etc. to not work properly if the text was anchored anywhere other than with GTK_ANCHOR_NORTH*. (_get_position): Hacked to cause objects to activate when they are double-clicked. There is probably a better way to do this. * gal/e-text/e-text-model.c (e_text_model_real_object_count): Provide a default implementation of an object counter. Derived classes might want to override this for efficiency reasons. (e_text_model_strdup_expanded_text): Added. Allocates and returns a string contains the model's text with the objects "expanded" within. * gal/e-text/e-text-model.h: Added obj_count, get_nth_obj, and activate_nth_obj virtual methods to ETextModelClass. svn path=/trunk/; revision=7842
