[Gtk-sharp-list] Gtk entry only for digits?

[Michael]

Jop, helped a lot :-)

I did it that way:

void InsertText(object o, TextInsertedArgs args)
        {                
                if(args.Text.Equals("1") || args.Text.Equals("2") 
                        || args.Text.Equals("3")
||                     args.Text.Equals("4") ||
                        args.Text.Equals("5") ||args.Text.Equals("6")
                        ||args.Text.Equals("7") ||args.Text.Equals("8")
                        ||args.Text.Equals("9") ||args.Text.Equals("0"))
                {
                        Console.WriteLine("Number pressed "+ args.Text);
                }
                else
                {                       
                        if(entry1.CursorPosition.Equals(0))
                        {
                                entry1.DeleteText(entry1.CursorPosition-2,entry1.CursorPosition-1);
                                Console.WriteLine("Text0: "+ args.Text);
                        }
                        else
                        {
                                entry1.DeleteText(entry1.CursorPosition,entry1.CursorPosition+1);
                                Console.WriteLine("Text1: "+ args.Text);
                        }
                }
        }

@ Draek: With KeyPressEventArgs you do not get any output in the console
if a digit is pressed. Only 'special keys' show an output.

Thanks a lot @ all
