Hi again,
I'm trying to get clutter script working with vala. I can't figure out how
to access my rectangle in its button-press-event handler. how can I define
the params of the handler to get access to the ui object? ...
thnx
using Clutter;
using GLib;
bool button_press (ButtonEvent event, Script ui) { // wrong
stdout.printf("%s", "button press event");
Rectangle rect = (Rectangle)ui.get_object ("rectangle"); // this
segfaults
//rect.set_color(Color.from_string("white"));
return true;
}
int main (string[] args) {
//Stage stage = Stage.get_default();
string filename = "gui_test.json";
if (Clutter.init(ref args) != Clutter.InitError.SUCCESS) {
stdout.printf("%s", "Error Initializing Clutter");
return 1;
}
Script ui = new Script();
uint merge_id = ui.load_from_file (filename);
if (merge_id == 0)
{
stdout.printf("%s", "Error Loading ClutterScript");
return 1;
}
ui.connect_signals (ui);
Stage stage = (Stage)ui.get_object ("stage");
/* make the objects in the script available to all signals
* by passing the script as the second argument
* to clutter_script_connect_signals()
*/
stage.show_all();
Clutter.main();
return 0;
}
[clutter script]
