Hi, guys
I’m new here; I met a problem with combo box.
Our platform modified gtk combobox for performance consideration. Now, it works
as following:
There is a variable called: defer_menu_creation, if set to True, then the items
under combobox will not be created during combobox creation.
They will be created when user clicking the combobox.
============================ >8===============================
static void
gtk_combo_box_menu_setup (GtkComboBox *combo_box,
gboolean defer_menu_creation)
{
…
g_signal_connect (combo_box->priv->button, "button_press_event",
G_CALLBACK (gtk_combo_box_menu_button_press),
combo_box);
g_signal_connect (combo_box->priv->button, "state_changed",
G_CALLBACK (gtk_combo_box_button_state_changed),
combo_box);
if (!defer_menu_creation)
gtk_combo_box_menu_create (combo_box);
else
combo_box->priv->menu_creation_pending = TRUE;
…
}
void
gtk_combo_box_popup (GtkComboBox *combo_box)
{
…
if (combo_box->priv->menu_creation_pending)
gtk_combo_box_menu_create (combo_box);
if (GTK_WIDGET_MAPPED (combo_box->priv->popup_widget))
return;
…
}
============================ 8<===============================
So, I firstly let LDTP (http://ldtp.freedesktop.org) to popup the combobox,
but, I still can not select item (by name) inside combobox.
gail_item_get_name inside gailitem.c doesn’t get the item name because
GTK_IS_COMBO_BOX(parent) return false. I don’t understand.
============================ 8<===============================
gail_item_get_name (AtkObject * obj)
{
…
if (name == NULL)
{
…
else if (GTK_IS_MENU_ITEM (widget))
{
…
parent = gtk_widget_get_parent (widget);
if (GTK_IS_MENU (parent))
{
...
if (GTK_IS_ACCESSIBLE (parent_obj))
{
parent = GTK_ACCESSIBLE
(parent_obj)->widget;
if (GTK_IS_COMBO_BOX (parent))
// Here will be FALSE,
{
…
}
============================ >8===============================
Is there anything I need to do to support this kind of combobox?
Thanks very much!
Alex
