Using Gtkmm - 2.22 on Win7 with MinGW.
Well, this is what I have done so far, based on what I understand from the
libsigc++ tutorial, what am I doing wrong?
class myEntry : virtual public Gtk::VBox {
private:
Gtk::Entry* ntrTest;
Gtk::Label* lblTest;
public:
sigc::signal<void> signal_detected; // gcc complains, if it is private??
myEntry();
virtual ~myEntry() {}
bool notifyOutofFocus(GdkEventFocus* event);
};
myEntry::myEntry() {
this->ntrTest = Gtk::manage(new Gtk::Entry());
this->ntrTest->signal_focus_out_event().connect(sigc::mem_fun(*this,
&jme::myEntry::notifyOutofFocus));
this->lblTest = Gtk::manage(new Gtk::Label("test", Gtk::ALIGN_LEFT));
this->pack_start(*lblTest);
this->pack_start(*ntrTest);
}
bool myEntry::notifyOutofFocus(GdkEventFocus* event) {
signal_detected.emit();
return false;
}
class runner : public Gtk::Window {
private:
Gtk::Button* btnapply;
Gtk::Button* btnexit;
Gtk::HBox* btnhb;
Gtk::VBox* vb;
jme::myEntry* mentry;
public:
runner();
~runner() {}
void apply() { /*do something*/ }
void close() { this->hide(); }
bool warn_people();
};
bool runner::warn_people() {
std::cout << "Warning people" << std::endl;
return false;
}
runner::runner() {
btnhb = Gtk::manage(new Gtk::HBox);
vb = Gtk::manage(new Gtk::VBox);
mentry = Gtk::manage(new jme::myEntry);
////////// >> compile time error !!
mentry->signal_detected.connect( sigc::mem_fun(*this,
&runner::warn_people) );
//////// <<< compile time error ends
btnapply = Gtk::manage(new Gtk::Button(Gtk::Stock::APPLY));
//btnapply->signal_clicked().connect( sigc::mem_fun(*this,
&runner::apply));
btnexit = Gtk::manage(new Gtk::Button(Gtk::Stock::CLOSE));
btnexit->signal_clicked().connect(sigc::mem_fun(*this, &runner::close));
vb->pack_start(*mentry);
btnhb->pack_start(*btnapply);
btnhb->pack_start(*btnexit);
vb->pack_start(*btnhb);
set_default_size(200, 50);
this->add(*vb);
this->show_all();
}
int main(int argc, char *argv[]) {
Gtk::Main kit(argc, argv);
runner jaime;
Gtk::Main::run(jaime);
return 0;
}
