Description Timothy Mowlem CLA 2010-08-27 11:16:44 EDT 
Build Identifier: 3.7M1 - 3.6.0 I20100608-0911

Running 3.7M1 on MacOSX when I click the toolbar button to toggle on block selection mode the font height or leading seems to change even though the font is the same for "text font" and "block selection text editor font", both Consolas 14 pt.

Interestingly the preview box in the Font pref pane in Preferences also shows this extra spacing out.

Reproducible: Always

Steps to Reproduce:
1. Open Eclipse
2. Open a java editor
3. Toggle block selection mode on

If i change to Droid Sans Mono 14 pt then I don't see the apparent height adjustment so looks like it is font specific.
Comment 2 Markus Keller CLA 2010-08-27 12:43:23 EDT 
SWT implements the drawing in StyledText.
Comment 3 Scott Kovatch CLA 2010-08-27 13:02:40 EDT 
I'm not seeing this in the top-of-tree of SWT. I set up Consolas 14 as both the plain and block-selection font and the font isn't changing. StyledText.setFont() isn't being called, either. I'll get 3.7m1 just to be sure.

Felipe, can you give it a try?

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
