[antlr-interest] Text focus bug in ANLTR works on Ubuntu make it unusable.

[Chris Dew]

Hi Everyone,

I've been interested in looking at ANTLR for several years.

There is a UI bug which prevents the foreground window's widgets from
gaining focus when you click on them.  The text cursor remains in the
background window, even when the foreground window is active and I
click in the Grammar Name widget.

The most ironic twist is that if you use the GIMPs screenshot facility
to get an image of the window, it will give focus to the foreground
window's widget.  Using GIMP screenshot for widget focus is not a
usable solution.  (The screenshot does not therefore show the issue.)

This bug has been present in all AntlrWorks / Ubuntu AMD64 releases
for at least two years and since at least Ubuntu 8.10.  (I try
AntlrWorks every six months or so.)

Things I've checked:

chris at chris-linux-desktop:~$ sudo update-alternatives --config java
There are 3 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                      Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061      auto mode
  1            /usr/bin/gij-4.4                           1044      manual mode
  2            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061      manual mode
* 3            /usr/lib/jvm/java-6-sun/jre/bin/java       63        manual mode

chris at chris-linux-desktop:~$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=10.10
DISTRIB_CODENAME=maverick
DISTRIB_DESCRIPTION="Ubuntu 10.10"

chris at chris-linux-desktop:~$ ls -lA antlrworks-1.4.3.jar
-rw-r--r-- 1 chris chris 3588307 2011-10-04 08:03 antlrworks-1.4.3.jar

chris at chris-linux-desktop:~$ java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)


Is anyone on this list successfully using AntlrWorks with Ubuntu AMD64?

Who is the administrator who I contact to get an account to submit a
bug?  http://www.antlr.org/jira/login.jsp?os_destination=%2Fbrowse%2FANTLR

Thanks,

Chris.
