In case that other newcomers like me are in doubt how to use your class, maybe it’s a good idea you tell the newcomer that you have written about it in the blog.

I guess one side-effect of that could be that more people also writes in the blog :-)

using System;
using Gtk;

public partial class MainWindow: Gtk.Window
{	
	public MainWindow (): base (Gtk.WindowType.Toplevel)
	{
		Build ();
	}
	
	protected void OnDeleteEvent (object sender, DeleteEventArgs a)
	{
		Application.Quit ();
		a.RetVal = true;
	}
}

The function with the Build() in it is the class’s constructor (i.e. the form’s constructor). You can put your code in there after the Build() line.

Any controls you’ve added to the form (in this case the TreeView) will be in scope here (note it’s a partial class, the rest of the class is built by the designer) so, assuming you’ve given the name “tvTest” to it in the stetic designer then you can use

SimpleTreeView tree=new SimpleTreeView(tvTest);

Finally, this
‘SimpleTreeView tree=new SimpleTreeView(controlOnForm);’
the controlOnForm, is that the same as the name I put in properties-pane in stetic designer.?
If so, how am I supposed to access it – as it iss burried within the autogenerated gtk-gui/MainWindow – file.?

As we are using System.Collections.Generic at the top that’s a clue that we’re not using non-generic collections, and those lines you quote have no type parameter.

They should actually read:

List<Gtk.TreeViewColumn> _cols;
List<Gtk.CellRendererText> _cells;

As angle brackets are used in HTML to specify tags I can see why they disappeared! I’m going to replace the whole code section as I see other bits like this aren’t displaying.

Edit: The code in the article has now been replaced.

After reading you last post here – I installed Opera – same result. Chromium – Same result. And finally Google Chrome, and now I see your code as it should be :).

But Ok, I copie-pasted the code from Chrome. And now no errors within the foor-loops.

But the compiler still complains about the
List _cols;
List _cells;
part
giving the error:
“Error CS0305: Using the generic type `System.Collections.Generic.List’ requires `1′ type argument(s) (CS0305) (A6)”

Instead of commenting out parts of that for loop, search your code for the string “&lt;” and replace it with “<“.

The confusing thing is when you post your code here any HTML entities such as &lt; get displayed as the character they represent :)

for(int n=0; n</*_cols.Count;*/ ++n){

the n< thing was a typo. If you want, edit away the typo from the last post and remove this one.

I commented out _cols.Count; .

for(int n=0; n< /* _cols.Count;*/ ++n).

AFAIK, that does no harm.?

But now it halts on the List declaration at the very beginning.

List _cols;
***CS0305: Using the generic type `Stack’ requires `1′ type argument(s)***

Maybe i am not implanting the code right. I am very new to MonoDevelop, and to gui-programming in general. So any advices would be avesome.

Is it to much ask for a working project.?

Other than that- your code seems to be very good, and I am sure that I could earn a lot from it If I only can get it to work,

Still the same problem.
If you wish I can send the project and the build log.

Type[] t = new Type[3];
t[0] = typeof(string);
t[1] = typeof(int);
t[2] = typeof(decimal);
foreach (var x in t)
{
Console.WriteLine(x);
}
