[Mono-winforms-list] MaskedTextBox.GetCharFromPosition Method

[aatdark at aol.com]

 Hi
I have written lots of nunit tests for the Function and they are all runnning well on MS .NET 2.0


 No i'm proceding with step 2.

for now i try to get the correct line with
Line line = document.GetLineByPixel(p.Y,false);



but the problem is: How can i get the char index from the position in pixels?
I can only use the 

LineTagToCharIndex

if i know the char index.

Because there could be different fonts. The only solution seems to be to call the Grapics.MeasureText method for each letter.

for example if the Text is:
HiTestText
I have to measure
H
Hi
HiT
HiTe
...

But this seems to be terrible slow?
Anyone a better solution for this ?

Yours,
Berni

You should probably start by unit testing TextBoxBase, I would just add
your tests to TextBoxTest at first, then we can add some more to
MaskedTextBox later.  But it is best to test from the bottom up.  Since
you will have to implement this feature from the bottom up.
