Hi,
It doesn’t make sense to use the manage() (widget life-cycle) function because
a Gtk::MessagDialog has no parent container. It’s like a Gtk::Window...
I recommend you this way to instantiate your MessageDialog into your
UIException constructor :
// declaration jit
Gtk::MessageDialog MyExceptionMessageDialog( *this,
“My message,,,,”,
False /*use markup*/,
Gtk::MESSAGE_QUESTION,
Gtk::BUTTONS_OK_CANCEL
);
MyExceptionMessageDialog.set_secondary_text(“once upon a time ...”); // just
for illustration
MyExceptionMessageDialog.run(); // start the message dialog
Int response = MyExceptionMessageDialog.run() // capture the user action
std::cout<<((response == Gtk::RESPONSE_OK) ? “you pressed OK” : “you pressed
cancel”)<<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:
1>------ Build starte[drive:] Project: vsApp, Configuration: Debug Win32 ------

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?
