I'm building a couple of designers and I would like to use the same drawing
that winforms classes use.
I managed to do this:

class ButtonComponent
{
}

class ButtonComponentDesigner
{
 Button b = new Button();
// b is synced with the ButtonComponent that we should design
}

When painting in the designer I want to draw using the logic from b. OnPaint
is protected so I had to inherit Button in my own class to access it. So
what I did was:

class FakeButton : Button
{
 public void DoFakePaint(PaintEventArgs e)
 {
    base.OnPaint(e);
 }
}

So now the designer becomes:

class ButtonComponentDesigner
{
 FakeButton b = new FakeButton();
// sync b like above with ButtonComponent

// when drawing just call b.DoFakePaint() and it works
}

This is all very good and it works but I have problems with the other
winforms controls: CheckedListBox, ComboBox, ListBox, PictureBox, TextBox -
they don't draw using this method.

Button, CheckBox, GroupBox, Label, LinkLabel all work perfectly.

Is it possible to steal the drawing form the more complicated controls?...
That's all I need, just for them to look the same, and doing it by hand
doesn't appeal to me.

Thanks.
