Description Mark McLaren CLA Friend 2005-08-06 19:27:01 EDT 
When running the sample Tree-with-columns snippet (Snippet170) I'm getting
'blurry' text in columns 2 and 3 after selecting an item.  It's like the
antialiasing has been applied many times.

Blurry text in columns 2 and 3

Attaching a screenshot of problem.  Note that the more you change the selected
tree item, the more blurry the text in columns 2 and 3 gets.

This WORKSFORME.  Are there some Windows settings I need to do to make this 
happen on my machine?
Comment 3 Mark McLaren CLA Friend 2005-08-08 18:18:25 EDT 
Sorry should have mentioned I have enabled 'Cleartype', Microsoft's nice little
antialising feature.  

Go to Control Panel -> Display -> Appearance, and select 'Clear Type'.  

Also, I'm using Windows XP Profession with SP2.
Comment 4 Steve Northover CLA Friend 2005-08-09 10:54:21 EDT 
Ok, I can make it happen now.

This has not been patched to 3.1.1.
Reopening to consider for 3.1.1.

Fixed in the maintenance stream > 20050909.
Comment 8 Veronika Irvine CLA Friend 2005-10-06 15:51:12 EDT 
Backed out change from 3.1.1 because it caused bug 111836
Comment 9 Florian Priester CLA Friend 2006-02-17 12:25:12 EST 
The problem is visible again in versions >= 3223. This bug should be reopened.
Comment 10 Steve Northover CLA Friend 2006-02-17 12:54:42 EST 
Ok then.

Fixed > 20060218 (again)

With all the recent changes to Tree, I keep forgetting that it is necessary to always fill the background where the text is drawn (ie. I fall for OS.SetBkMode (hDC, OS.TRANSPARENT)).  Thanks for keeping me honest.  Hopefully I won't fall for it again for 3.2!
