Edje Text example
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);
_on_text_change(void *data __UNUSED__, Evas_Object *obj, const char *part)
- 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:
edje_object_part_text_set(edje_obj, "part_one", "one"); edje_object_part_text_set(edje_obj, "part_two", "<b>two");
- 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:

The full source code follows:

The theme used in this example is:
collections { group { name: "sel_group"; parts { part { name: "rect"; type: RECT; description { state: "default" 0.0; color: 0 255 0 255; /* green */ rel1.relative: 0.0 0.0; rel2.relative: 1.0 1.0; } } } } group { name: "example_group"; max: 500 500; min: 50 50; styles { style { name: "textblock_style"; base: "font=Sans font_size=22 color=#600 wrap=word"; tag: "br" "\n"; tag: "hilight" "+ font_weight=Bold"; tag: "b" "+ font_weight=Bold"; tag: "tab" "\t"; } } parts { part { name: "part_one"; type: TEXT; description { min: 50 50; state: "default" 0.0; color: 0 0 255 255; /* blue */ rel1.relative: 0.0 0.0; rel2.relative: 1.0 0.5; text { font: "arial"; size: 22; min: 1 1; } } } part { name: "part_two"; type: TEXTBLOCK; select_mode: EXPLICIT; source: "sel_group"; entry_mode: PLAIN; description { min: 50 50; state: "default" 0.0; rel1.relative: 0.0 0.5; rel2.relative: 1.0 1.0; text { style: "textblock_style"; min: 1 1; } } } } } }
