A DESCRIPTION OF THE PROBLEM :
23-apr-2002

Painting of MotifRadioButton (and other buttons) is faulty.

Due to several bugs, a RadioButton is drawn incorrectly.
One bug, 4126679, reported already that the insets were
not taken into account when drawing in BasicRadioButtonUI.
Other problems are:
o in MotifIconFactory.RadioButtonIcon the start position
for drawing the icon is shifted right by 2.
This seems to be just a hack to fix the problem
really caused by not taking the insets into account
when painting, see above.
(( Same in CheckBoxIcon; others? ))
o MotifIconFactory.RadioButtonIcon says it is 13 wide and 13
high.
In its paint method lines are drawn from coordinates x+0
through x+13, and y+0 through y+13. Thus the icon is really
14 wide and 14 high.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
o split the enclosed source into files:
MyMetalLAF.java
MyMetalRadioButtonUI.java
MyMotifIconFactory.java
MyMotifLAF.java
MyMotifRadioButtonUI.java
MyRadioButton.java
MyWindowsLAF.java
MyWindowsRadioButtonUI.java
T01.java

o compile the files into a directory
o start T01 using one of:
<java-invocation> -Dlaf=windows T01
<java-invocation> -Dlaf=metal T01
<java-invocation> -Dlaf=motif T01
to have the program use one of its mini-lafs: MyWindowsLAF,
MyMetalLAF
and MyMotifLAF respectively

The program displays three labels and three RadioButtons.
The left RadioButton is an original swing JRadioButton.
The middle RadioButton is a MyRadioButton, behaving just
like the
standard JRadioButton, except that it paints its areas computed
by the paint method in its UI:

light blue : background of widgets
yellow : viewR: union of iconR and textR
light green: iconR: the rectangle into which the icon should
be drawn
light red : textR: the rectangle into which text should be drawn

The right RadioButton is a MyRadioButton, using fixes for
the problems,
except the one that the Motif icon reports a wrong size. It also
paints its areas like the middle button.

Methods were copied from jdk 1.4.0 sources as mentioned in
the sources.
Changes are marked:
//x : line is commented out
//{ : start change
//} : end change

  To localize fixes, search for "FIXED".

This bug can be reproduced always.
