Re: EventListener
One way is to store your frame somewhere in your MIActionListener. With
minimum changes in your code you can write like this
menulistener.addActionListener(new MIActionListener(this));
class MIActionListener implements ActionListener{
Frame f;
MIActionListener(Frame f) { this.f = f; }
public void actionPerformed(ActionEvent Ae){
f.setBounds(...); //...
}
}
Commonly used (but probably not the best) way to shorten code is to use
anonymous internal class in this manner:
menulistener.addActionListener(new MIActionListener()
{
public void actionPerformed(ActionEvent Ae){
JFrame.this.setBounds(...); //...
}
});
Hope this helps
All the Best

Coredump
Hi. I installed jre1.2 pre-v2 on my slackware machine running glibc 2.0.4. Everytime I try to run "java", i get a coredump. Has anyone else had this problem before? Thanks.

jdk for alpha (redhat 6.0)?
Hi, does anyone know if there is a port in the works for Alpha (EV56) running RedHat 6.0? I saw a message about it from a couple months ago and I was wondering if there was any update. I don't see anything about it on the JCK page. Also will it support JNI? Thanks. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
Status of JDK1.2

RH5.0 and JDK1.2 -> Segmentation fault
Hello! I've got a RH5.0 running on a I386. I previously installed JDK117 and it was running perfect. Now a customer needs JDK1.2 and I downloaded glibc2.0-version last week. The first problem running ./java in the /bin-directory was libjava.so. I fixed it by editing the .wrapper...-file and hardcoding APPHOME-Path. When I now try to run ./java or java I get a "segmentation fault (Core dumped)"-error instead of the usage. Where is the problem ??

RE: Problems installing JDK 1.1.7 and JDK 1.2 pre-v2
Hi guys... I have finally managed to install JDK1.1.7_v1a and JDK1.2... You won't imagine what I was doing wrong! As I previously wrote, I did download the proper archives (all of them, and not only the native threads one, as somebody suggested). Also, I wasn't running from the /bin directory (which is problematic only for JDK 1.2, anyway). What happened is that, to download the tar files, I used an NT machine, linked to my Linux PC via Samba. So far so good. But, being lazy in typing "tar -xvf" under Linux, I used WinZip to un-tar and then copied the extracted files into the Linux JDK directory (1.1.7 or 1.2, respectively) directly. Well, I don't know why (please somebody explain), but with this procedure I kinda "lost" files during the WinZip extraction!!! The jdk/bin directory contained only a few of the scripts, (.java_wrapper, java-rmi.cgi, checkVersions, and jre for JDK1.1.7 and only the first two of these for JDK 1.2)!!! Weird! So far I have un-tared several archives with WinZip, without any problems. Is there any shell script automatically running after un-taring with tar, which (reasonably) WinZip cannot execute? I know have a silly problem with JDK 1.1.7. Namely, while I can compile my application (containing several .java files organised in a number of packages), when I attempt to run it, it doensn't run! My environment is $JAVA_HOME = $CLASSPATH = .:$JAVA_HOME/lib/classes.zip:$JAVA_HOME/swingall.jar I can compile the source files from whichever directory I want (typing $JAVA_HOME/bin/javac /*.java) without any problems. However, when I try running a (just compiled) class, even from its directory, I get a "Can't find class" message. When I attempt the (not-so-redundant-as-I-believed) command $JAVA_HOME/bin/java -classpath $CLASSPATH I get a "Unable to initialize threads: Can't find java/lang/Thread" message. I have even played with the scripts in $JAVA_HOME/bin, inserting debugging comments, and they seem to be after the correct path... This must be a really silly error, could someone please help? I suspect all this has to do with paths, since JDK 1.2 works just fine... > Also, is version 3 of the Linux jdk1.1.7 implementation for libc2.0 (as > well as libc2.1) or not?

Is JVMDI supported ?
Does JDK 1.2pre2 support Java Virtual Machine Debug Interface (JVMDI)? My understanding is that it is a C API described in JDK_ROOT/include-old/jvmdi.h.

RE: Problems installing JDK 1.1.7 and JDK 1.2 pre-v2
Hello again... I think I 've solved most of the silly problems I was experiencing, thanks for your help and advises... The only one remaining is a NullPointerException I 'm getting when launching my application from JDK 1.1.7. It has to do with the initial JFrame. The interpreter resolves this to the Motif peer, so I suspect it is related to Swing (JFC 1.1.1). I haven't seen any Linux-specific JFC port, so what I did is I included the swingall.jar file from the Javasoft Solaris distribution of JFC 1.1.1 (which is an identical file to the Win32 distribution, by the way). Is anyone aware of any bugs/problems (and solutions) in Swing 1.1.1 support for JDK 1.1.7 in Linux? Cheers, Dimitris -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Re: Problems installing JDK 1.1.7 and JDK 1.2 pre-v2
Actually, I believe the problem is related to the fact the NT doesn't support symbolic links. Almost all the files in the ($JAVA_HOME)/bin directory are symbolic links to .java_wrapper. The only two files that aren't symbolic links are .java_wrapper and java-rmi.cgi (atleast on 1.2).

display problem I need some advice and help
Hello, I use JDK 1.1.7 v3 linux and latest version of all program and libs that ship with redhat I devlop program using a windows GUI (powerJ) I want to use my what I develop in MS windows under linux. I have 2 problems (i am using the same screen resolution under MS win and X) : - The windows are not the same size under MS win it depend on the pixel and it seems that under X it depend on the font used for X.(I have not a good idea how to control those fonts and how to make a match between the screens MS win => X) Is there any solution ? - Under MS win a SetEnable(false) text field is readable it only change color. Under X not but i want to be able to read it. Using setEditable() might have been the solution but then when you "TAB" between text field it entre the also the non editable field which is use less and i want to avoid that. I know that it is X that deal with the disable, enable text look/font/display Is there a way to work around this ?
