Gtk+-2.0 Calling constructor [language C]

Four · 05-29-2008, 02:43 PM

Hi,

I'm making a widget and deriving it from a GtkVBox. How do I call the constructor of the GtkVBox? Looking at the tutorial on tictactoe widget. The widget is derived from the GtkTable, however there is no gtk_table_new()?

Thank you

Let's have this exampple:

Code:

class A
{
 A();
}

class B: public A
{
 B();
}

When you have

Code:

  B b;

it calls the constructor of B (B()) and the constructor of A (A()). So in your case, the constructor for the GtkVBox will be called automatically, after the call your widgets constructor.

Thank you LordAnta,

Unfortunately I'm dealing with only C without the C++ extensions working with GTK+-2.0 API. I made a widget using GtkTable like in the example, but I think (for my purposes) it would be better to use a GtkVBox.I don't understand how the GtkVBox will be initialized and how to change some of its parameters.

sorry, totally forgot that GTK is only in C. Too much Qt and OOP for me the in the last few days

L.E.: found this example on google: http://www.linuxheadquarters.com/how...box/vbox.shtml

Code:

  GtkWidget *vbox;
  vbox = gtk_vbox_new(FALSE,0);

Hope it helps.
