Hi everybody,
I'm experiencing some difficulties with a Gtk::Dialog built with Glade which I
instantiate from somewhere (I don't think it's relevant, but the somewhere is
just a Gtk::window...).
Basically, when I run it the first time, all is fine. When I run it a second
time or plus, the Gtk::Dialog becomes empty except for the dialog title :-/ I
think I'm doing something wrong... but where `??? All parameters of the
Gtk::Dialog are defined into the XML Glade.
I copy paste the relevant parts of my source below
Regards
////////////////////// the instantiation from the parent window
void metadataWindow::on_exportEBUCore_clicked(void){
metadataEncapsulationDialog * MetadataExportDialog;
// instantiate glade dialog
m_refGlade->get_widget_derived("MetadataExportDialog",MetadataExportDialog);
if (MetadataExportDialog->getResponse() == Gtk::RESPONSE_OK)
std::cout<<"it works, I pressed the save button..."<<std::endl;
// free memory
delete MetadataExportDialog;
}
