FULL PRODUCT VERSION :
java version "1.6.0_10-beta"
Java(TM) SE Runtime Environment (build 1.6.0_10-beta-b21)
Java HotSpot(TM) Client VM (build 11.0-b11, mixed mode, sharing)
This bug is all the 6uX releaes;ie, 6u3, 6u4, 6u5, 6u6
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]
A DESCRIPTION OF THE PROBLEM :
The default width for a JFormattedTextField is often too narrow by a pixel or two. In both Windows and Metal look and feels. With the Windows look and feel this can actually cut off a pixel of text. In both look and feels there is a horizontal shift while selecting and editing.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run sample code.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The content of the JFormattedTextField in the example is fixed length and should not shift horizontally while editing. The leading pixels of the first '0' should not be clipped initially.
ACTUAL -
clipped pixels, horizontal shifts while editing and selecting.
REPRODUCIBILITY :
This bug can be reproduced always.
