This example shows how to manipulate TEXT and TEXTBLOCK parts from code.
The very first we are going to do is register a callback to react to changes in the text of our parts:
edje_object_text_change_cb_set(edje_obj, _on_text_change, NULL);
- Note
- Since edje_obj represent a group we'll be notified whenever any part's text in that group changes.
We now set the text for two our two parts:
- Note
- Since the "part_two" part is a TEXTBLOCK we can use formatting such as <b>
And we now move on to selection issues, first thing we do is make sure the user can select text:
edje_object_part_text_select_allow_set(edje_obj,
"part_two",
EINA_TRUE);
We then select the entire text, and print the selected text:
printf("selection: %s\n", edje_object_part_text_selection_get(edje_obj, "part_two"));
We now unselect the entire text(set selection to none), and print the selected text:
edje_object_part_text_select_none(edje_obj, "part_two");
printf("selection: %s\n", edje_object_part_text_selection_get(edje_obj, "part_two"));
Our example will look like this:
