[Mono-winforms-list] Question about CommonDialog implementation

[Aleksandar Dezelin]

I don't understand, why are we making the instance of the DialogForm in 
the CommonDialog constructor? CommonDialog is an abstract class so one 
should make an instance of his own class inherited from DialogForm class 
like FontDialogForm in FontDialog constructor. This way we have one 
useless DialogForm instance.

Another thing. When I create an instance of FontDialog class, current 
Dialog implementation calls 
CommonDialog.DialogForm.FormParentWindow.CreateParams with undefined 
'owner' field and trows an exception. I've tracked it down, and found that
this internal c'to gets called:

internal FormParentWindow(Form owner) : base() {
...
}

which calls Control() c'tor that checks CreateParams property which is 
virtual and dependent on the 'owner' field' that's never been assigned 
so far.

Cheers,
Aleksandar Dezelin
