[jira] Created: (HARMONY-2243) [classlib][swing] j.s.text.GlyphView
incorrectly measures itself where text has tabs
[classlib][swing] j.s.text.GlyphView incorrectly measures itself where text has tabs
------------------------------------------------------------------------------------
Key: HARMONY-2243
URL: http://issues.apache.org/jira/browse/HARMONY-2243
Project: Harmony
Issue Type: Bug
Components: Classlib
Reporter: Alexey A. Ivanov
In situations where text has tabs, javax.swing.text.GlyphView will incorrectly measure itself which prevents the right layout.
GlyphView doesn't measure itself directly, it delegates to GlyphPainter instance and uses its getSpan() method. The method has x as one of its parameters, and it is used for tab expansion, which does depend on start coordinate. And this x is always 0.0 in Harmony.

[jira] Updated: (HARMONY-2243) [classlib][swing] j.s.text.GlyphView
incorrectly measures itself where text has tabs
Posted by "Alexey A. Ivanov (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/HARMONY-2243?page=all ]
Alexey A. Ivanov updated HARMONY-2243:
--------------------------------------
Attachment: H2243-GlyphViewTest.patch
This new test case demonstrates the problem, however indirectly.
It looks like during layout process each of GlyphViews gets notified somehow where it will be located, which is not the case for Harmony at the moment.
