LQL# HTB control

Now that LQL-Sharp has been released I thought I should put together a quick little demonstration of just how cool it is.

I have created a extremely simple GUI control that can modify the rate and ceiling parameters of a HTB class. This control should really subclass Gtk.Widget but it serves its purpose as is.

using System;
using Gtk;
using LQL;
class HTBControl {
	private LQL.ClassHTB klass;
	private LQL.Con con;
	private Gtk.SpinButton rateSpin;
	private Gtk.SpinButton ceilSpin;
	public HTBControl(LQL.ClassHTB klass, LQL.Con con)
	{
		this.klass = klass;
		this.con = con;
		Gtk.Window myWin = new Gtk.Window("TC GTK+");
		myWin.DeleteEvent += new DeleteEventHandler(WindowDelete);
		Gtk.VBox vbox = new Gtk.VBox(false, 3);
		Gtk.HBox hbox1 = new Gtk.HBox(false, 2);
		hbox1.Add(new Gtk.Label("Rate (bytes/sec): "));
		this.rateSpin = new Gtk.SpinButton(0, 10000000, 1);
		hbox1.Add(this.rateSpin);
		vbox.Add(hbox1);
		Gtk.HBox hbox2 = new Gtk.HBox(false, 2);
		hbox2.Add(new Gtk.Label("Ceiling (bytes/sec): "));		
		this.ceilSpin = new Gtk.SpinButton(0, 10000000, 1);
		hbox2.Add(this.ceilSpin);
		vbox.Add(hbox2);
		Gtk.Button modifyButton = new Gtk.Button("Modify");
		modifyButton.Clicked += new EventHandler(Modify);
		vbox.Add(modifyButton);
		rateSpin.Value = this.klass.Rate;
		ceilSpin.Value = this.klass.Ceiling;
		myWin.Add(vbox);
		myWin.ShowAll();
	}
	static void WindowDelete(object o, DeleteEventArgs args)
	{
		Gtk.Application.Quit();
		args.RetVal = true;
	}
	void Modify(object o, EventArgs args)
	{
		this.klass.Rate = (uint) this.rateSpin.Value;
		this.klass.Ceiling = (uint) this.ceilSpin.Value;
		this.klass.Modify(this.con);
	}
}

using System;
using Gtk;
using LQL;
class MainClass {
	public static void Main(string[] args)
	{
		Application.Init();
		LQL.Con con = new LQL.Con();
		LQL.Interface nIf = con.FindInterfaceByName("eth0");
		GLib.List classes = con.ListClasses(nIf);
		foreach (LQL.Class klass in classes) {
			if (klass is LQL.ClassHTB) {
				new HTBControl((LQL.ClassHTB) klass, con);
			}
		}
		Application.Run();
	}
}
