The problem is that i'm using a class to create this new window. In my
main.cpp I have this:
gtk_signal_connect_object (GTK_OBJECT(button), "clicked",
GTK_SIGNAL_FUNC(create_param_window),
GTK_OBJECT (window));
And the callback create_param_window look like this:ç
void create_param_window(GtkWidget *widget)
{
ParamWindow* NewParamWindow = new ParamWindow(widget);
gtk_widget_show(NewParamWindow->GetWidget());
}
(With GtkWidget* GetWidget() { return _pwindow; } in my ParamWindow.h )
And it's the constructor of the ParamWindow class who makes
_pwindow = gtk_window_new (GTK_WINDOW_TOPLEVEL);
So, I want to create only one "ParamWindow" when THIS button is clicked,
but maybe I want to create later another window using my ParamWindow
class for any other purpose.
Is there anyway to do this? It's quite important for the project I'm
working in.
Thanks,
Ignacio Nodal
