Re: [gtkmm] label en button_press_event problems

[bart <bart hakvoort castel nl>]

Thanks, it compiles now, but it doesn't seem to be working. Below is the
relevant part of my code:

--------PresenceWindow.hh---------------------------------------
class PresenceWindow : public Gtk::Window
{
	Gtk::VBox vboxMain;
	Gtk::Label testlabel;
	
public:
	PresenceWindow();
	bool labelklik(GdkEventButton *);

};
----------------------------------------------------------------

--------PresenceWindow.cc--------------------------------------
#include "PresenceWindow.hh"

PresenceWindow::PresenceWindow()
{
	testlabel.set_text( "TEST" );
	testlabel.signal_button_press_event().connect( SigC::slot(
*this,&PresenceWindow::labelklik )  );
 	vboxMain.pack_start( testlabel );

	show_all();
}

bool PresenceWindow::labelklik(  GdkEventButton* event  )
{
	std::cout << "LABEL --- check!!\n";
	return true;
}
-------------------------------------------------------------------

Making the label sensitive makes no difference. Does anyone know what
i'm doing wrong?

thnks!
bart
