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:
_on_text_change(
void *data EINA_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:
- 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:
We then select the entire text, and print the selected text:
We now unselect the entire text(set selection to none), and print the selected text:
Our example will look like this:
The full source code follows:
#ifdef HAVE_CONFIG_H
# include "config.h"
#else
# define EINA_UNUSED
#endif
#ifndef PACKAGE_DATA_DIR
#define PACKAGE_DATA_DIR "."
#endif
#include <Ecore.h>
#define WIDTH (300)
#define HEIGHT (300)
static void
_on_delete(Ecore_Evas *ee EINA_UNUSED)
{
}
static void
_on_text_change(
void *data EINA_UNUSED,
Evas_Object *obj,
const char *part)
{
}
int
main(int argc EINA_UNUSED, char *argv[] EINA_UNUSED)
{
const char *edje_file = PACKAGE_DATA_DIR"/text.edj";
Ecore_Evas *ee;
return EXIT_FAILURE;
goto shutdown_ecore_evas;
if (!ee) goto shutdown_edje;
return EXIT_SUCCESS;
shutdown_edje:
shutdown_ecore_evas:
return EXIT_FAILURE;
}
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;
}
}
}
}
}
}
To compile use this command:
* gcc -o edje-text edje-text.c -DPACKAGE_BIN_DIR=\"/Where/enlightenment/is/installed/bin\" -DPACKAGE_LIB_DIR=\"/Where/enlightenment/is/installed/lib\"
* -DPACKAGE_DATA_DIR=\"/Where/enlightenment/is/installed/share\"
* `pkg-config --cflags --libs evas ecore ecore-evas edje`
