Problems using gtk on object-oriented attempt
Hello,
Since lately, I am trying to write every code only more in C++ instead of
C.
Unfortunately I have problems handling gtk signals while using the
object-oriented attempt of C++.
I could write something like this...
#include
#include
using namespace std;
static void destroyWindow(GtkWidget *widget, gpointer data) {
gtk_main_quit();
}
class EmptyWindow {
private:
GtkWidget *window;
public:
void paintWindow(int argc, char **argv);
};
void EmptyWindow:
aintWindow(int argc, char **argv) {
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
g_signal_connect(G_OBJECT(window), "destroy", G_CALLBACK(destroyWindow), NULL);
gtk_widget_show(window);
gtk_main();
}
int main(int argc, char **argv) {
EmptyWindow *emptywindow = new EmptyWindow();
emptywindow->paintWindow(argc, argv);
return 0;
}
It actually works, but this signal function on top hurts the
object-oriented attempt, so how can I use signals with real methods, in
this case methods of "EmptyWindow"?
When i define a real method, I don't know how to access it with
g_signal_connect, due to its parameter.

Why not switch to use gtkmm - an object oriented layer on-top of gtk?

When I use these libraries, does that mean that people have to download
these libraries first to be able to compile the program (e.g. with a
make file to this program) or does it run anyhow with the usual gtk? I
guess a compiled program runs over gtk, but if someone wants to compile
it with a make file, he needs to download the three needed libraries
first. At the moment I am downloading it and see that I need libsigc and
glibmm for using gtkmm and I read that I naturally have to bind in other
header files than gtk/gtk.h. When someone wants to use my program, which
should be built with a makefile, he has to download these libraries too,
which is associated with work and the next problem is the compatibility to
Windows. At the moment I don't write anything for Windows and it's
possible to use the standard gtk on Windows too, so it wouldn't be a
problem to port programs to Windows. I found information about a gtkmm
runtime environment but who knows if this is as stable as the usual gtk
library.

Right -- if they're going to use the code, they have to have the
libraries. If they've got a reasonable distribution, though, getting
them is easy enough not to be a problem.

Actually you are right and if someone want's to get a program, it's
probably the least he can do to use it.
