How can I add image before the label like a warning sign?? and how can I make bold the label?? Thanks!
OkCancelDialog::OkCancelDialog():Gtk::Dialog( "Clear all calls", false ){
Gtk::VBox * vbox = get_vbox();
Gtk::Table * table = new Gtk::Table( 2, 1, false );
Gtk::Label * label = new Gtk::Label( "Please Confirm..." );
//Gtk::Image * image = new Gtk::Image("dialog-warning.png"); <----this is wrong!
vbox->pack_start( *table, false, false );
add_button( Gtk::Stock::CANCEL, Gtk::RESPONSE_CANCEL );
add_button( Gtk::Stock::OK, Gtk::RESPONSE_OK );
//table->attach( *image, 0, 1, 1, 2 );
table->attach( *label, 1, 2, 1, 2 );
vbox->show_all();
set_default_size(100, 80);
}
