RE: Gtk::MessageDialog

["Dos Santos, Oliveira" <dossantos ebu ch>]

Hi,

 

It doesnât make sense to use the manage() (widget life-cycle) function because a Gtk::MessagDialog has no parent container. Itâs like a Gtk::Window...

 

I recommend you this way to instantiate your MessageDialog into your UIException constructor :

 

// declaration jit

Gtk::MessageDialog MyExceptionMessageDialog( *this,

ÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂ âMy message,,,,â,

ÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂ ÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂFalse /*use markup*/,

ÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂ Gtk::BUTTONS_OK_CANCEL

ÂÂÂÂÂ ÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂ);

MyExceptionMessageDialog.set_secondary_text(âonce upon a time ...â); // just for illustration

MyExceptionMessageDialog.run(); // start the message dialog

Int response = MyExceptionMessageDialog.run() // capture the user action

std::cout<<((response == Gtk::RESPONSE_OK) ? âyou pressed OKâ : âyou pressed cancelâ)<<std::endl;

I am trying to create a gui interface for my Exception class, but I am getting some

errors from GTKmm library, this is the error message:

Earlier I was hit a wall like the one I am hitting now, but soldatov cleared things up when informed me that, since I am using VS10, I need to add this line in the main.cpp
int main( int argc, char **argv );
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine,int nCmdShow){
return main (__argc, __argv);
}

Now, could this problem be because I need to add other code than the one used in the examples? This is the code:

uiexception.hpp
~~~~~~~~~~~~~~~~
#ifndef UIEXCEPTION_HPP
#define UIEXCEPTION_HPP

#include "../../exception/exception.hpp"
#include <gtkmm/messagedialog.h> //<-- remove

namespace ns{
 class uiexception : virtual public Exception{
 public:
  uiexception();
  virtual ~uiexception()throw(){}
 private:
  Gtk::MessageDialog* dialog; //<-- remove
 };
}

#endif
--------------------------

uiexception.cpp
~~~~~~~~~~~~~~~
#ifndef UIEXCEPTION_HPP
#include "uiexception.hpp"
#endif

ns::uiexception::uiexception(){
 dialog = Gtk::manage(new Gtk::MessageDialog(
 " message",  //Message
 false, // Markup
 Gtk::MESSAGE_WARNING, //MessageType
 Gtk::BUTTONS_OK,      //Buttons
 false));               //modal
}

what could be causing this error messages?
