GtkListStore - stop editing a cell after "editing-started"

Hi,

Code:

void cell_end_edit(   GtkCellRenderer *cell,
                            GtkCellEditable *editable,
                            const gchar           *path_string,
                            gpointer         data ) {
   int i = 1;
   
}

void cell_start_edit( GtkCellRenderer *cell,
                            GtkCellEditable  *editable,
                            const gchar *path_string,
                            gpointer data ) {
   if ( GTK_IS_ENTRY( editable )) {
      .
      .
      do "something" here. 
      .
      . 
      gtk_cell_renderer_stop_editing( cell, TRUE );
   }
}

..
   renderer = gtk_cell_renderer_text_new ();
   g_object_set( G_OBJECT( renderer ), "editable", TRUE, "editable-set", TRUE, NULL );
   g_signal_connect( G_OBJECT( renderer ), "editing-started", ( GCallback )cell_start_edit, NULL );
   g_signal_connect( G_OBJECT( renderer ), "editing-canceled", ( GCallback )cell_end_edit, NULL );

After doing "something" i call "gtk_cell_renderer_stop_editing( cell, TRUE )" and "editing-canceled" singnal is send by cell. But the cell remain in edit mode and i must press "Esc" to exit from edit mode.
How can i solve that ?
Or maybe how can i detect a mouse click on a cell ?
Thanks !

Hi.

I thunk you're calling gtk_cell_renderer_stop_editing() too soon. General rule when using anything tree view is not to call signal emitting functions from signal handlers, since this can easily leave tree view in bad state. Try calling that function from idle handler, which will give tree view enough time to set straight it's internal state.

Cheers,
Tadej

@tadeboro
I believe you have right.
Is better to detect a mouse click on a cell.
I must read docs for that.

thanks.
