 Posted: Tue Aug 29, 2006 7:01 pm Post subject: Treeview - Activate row |
 |
|
Hi,
in my tool, i have a treeview as primary navigation... if a user quits the programm, all settings are stored to an history file. Also the last visited point in the navigation.
If a user restarts the tool, all data are shown like the last time.
No problem at all... that works fine....
BUT...
How can i hilight the last selected navigation point in my primary navigation treeview. What kind of data have i to store in my history file (plaintext). For all other data, i store a eccident-string as index (eg. gba, snes, gen) here....
Please give me some demo-code, if possible....
Thank you and regards,
andreas |

| Get the GtkTreeSelection object for the view, and get all selected rows (iters). Store their indices in your history file, and set them again when loading the program. |

Use the manual, or Dev_Inspector. It will show you that GtkTreeSelection has several select_* methods:
| Code: |
select_iter(GtkTreeIter $iter);
select_path($path);
select_range($start_path, $end_path);

Hm, i think, in the documentation i use at home (no internet connection availeable  ), these select_* methods arenīt documentated...  Hope, this will help, but i think so.
Where can i get the latest download-version of the php-gtk2 documationation? Everytime i download the docu, i get the php-gtk1 docu
I know, that you are one of the manual-writer .... thank you for the good job.
Is there a possibility, that there will be a php-gtk2 docu in extended chm like the php-docu found here: http://www.php.net/docs-echm.php

Thank you for this link....
Ok, finaly i found the way but having some problems:
| Code: |
/**
* First try! Not running
*/
// SET
list($model, $iter) = $obj->get_selected();
if ($iter) {
$this->ini->write_ecc_histroy_ini('nav_iter', base64_encode(serialize($iter)), false);
}
// GET
$treeview_nav_selection = $this->treeview1->get_selection();
if ($selected_iter = $this->ini->read_ecc_histroy_ini('nav_iter')) {
$iter = (unserialize(base64_decode($selected_iter)));
$treeview_nav_selection->select_iter($iter);
}
// RESULT
PHP Fatal error: Internal object missing in GtkTreeIter wrapper in D:\emuControlCenter-DEVEL-SQLITE2\ecc-system\ecc.php on line 543
Fatal error: Internal object missing in GtkTreeIter wrapper in D:\emuControlCenter-DEVEL-SQLITE2\ecc-system\ecc.php on line 543
/**
* Second try! Works fine!
*/
// SET
$treeview_nav_selection = $this->treeview1->get_selection();
if ($selected_iter = $this->ini->read_ecc_histroy_ini('nav_iter')) {
$treeview_nav_selection->select_path($selected_iter);
}
// GET
list($model, $iter) = $obj->get_selected();
if ($iter) {
$path = $model->get_path($iter);
$this->ini->write_ecc_histroy_ini('nav_iter', current($path), false);
}
|
Maybe you can say, why the first attemp is not running!

Seems like a bug in php-gtk. The "internal object missing" usually comes when you derive your own class from a php-gtk class and don't call the parent constructor in your own constructor.
Unserializing iters doesn't work, and you shouldn't try to serialize them at all. Use the row position or so, since iters are temporary objects only. |
