JDialog not visible
Hi, Following is a code which i use to invoke a JDialog on Red Hat 7.0 using blackdowns jdk1.2.2. But the Dialog doesn't seem to be visible. I see that it is being created at the status bar,but it still doesn't show up The same code works perfectly well on Windows NT. Can anybody tell me the reason behind it. Note: The following code is in an applet. /*Code Start*/ JDialog npd=new JDialog(Dialog d,String s); npd.show(); npd.setSize(250,250); /*Code End*/ Q)Why there is diference between presentation of applets in windows and linux? Thanks and Regards Amol -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

Amol, Some more context would be helpful. This behavior may be dependent on something you're not showing; can you provide a complete, small program and indicate how you run it? As for your question about different presentation, again - some more detail please... are you talking about the look and feel of the GUI, the JDialog display problem, or something else entirely?

Can anybody tell me > the reason behind it. I don't remember the specific details, but the gist of the problem is that the native peers for JWindow, JDialog, and JFrame perform some native pack()/revalidate() calls on their own, masking the need to do them in Java. I've encountered a number of apps written by windows developers which behave this way on Solaris and Unix because the java code doesn't call the *validate() methods it needs to be calling. I'm sorry, but I don't remember the specifics. The last time I had source available to fix this was 8 months ago and I've long forgotten what I had to fix. > /*Code Start*/ > JDialog npd=new JDialog(Dialog d,String s); > npd.show(); > npd.setSize(250,250); > /*Code End*/ Shouldn't you do the setSize() before the show()? -- Joi EllisSoftware Engineer Aravox Technologies [EMAIL PROTECTED], [EMAIL PROTECTED] No matter what we think of Linux versus FreeBSD, etc., the one thing I really like about Linux is that it has Microsoft worried.

Java on Linux talks at Javaone?
Hi all, Is Calvin or anyone else giving any talks on their work to get the latest JDK and Hotspot going on Linux? Calvin sent some intriguing hints about the work he had to do to get Hotspot performing well on Linux, but I'd like more info or even documentation on it. Also, who is using native threads in production using Sun's JDK 1.3. I am planning on porting a Jakarta/Tomcat/JSP app from Solaris to Linux and would like to hear from those who are using the latest and greatest in production. (i.e. what is the most stable highest performance setup?) Thanks, Ed Phillips -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

j2sdk 1.3.0 for sparc-linux?
I really /need/ j2sdk 1.3.0 running on sparc-linux to run some java clients on my sparc box, what's the status on this one? The last news item dates back to September 2000 and there's been nothing new since. I do have j2sdk 1.2.2, but this doesn't seem to work with the client I'm using. I'm really desperate, I'll even help beta, or even alpha test sparc-linux j2sdk binaries. Or if you have no sparc boxes, I can help with that. System configuration: Linux kernel 2.2.19 glibc 2.1.3 binutils 2.10.1 gcc 2.95.3 not forgetting X11 - Xfree86 4.0.3. running on sparc32.

Re: JDialog not visible
I have also encountered the same "symptom", when a file dialog menu was shown for a second time. The first time presented it it displayed. The second, and all other times is was created 'minimized' ( i.e. on the task bar ). This, I think, is a bad interaction between the awt & the motif used to do the linux port. There is an #ifdef linux fix in the area that causes the problem in jdk1.3.1, but the true test was the actual running of the intel jdk binaries which no longer exhibited the problem. On other linux platforms, with sharable metrolink motif, one has to nuke the code under the #ifdef linux for it to work properly ( for that instance ). /gat btw i cannot tell u what code ( jdialog, or otherwise ) was being used, as all I had was .class files.

Blackdown J2SDK 1.4 port?
Since Sun released their J2SDK 1.4 beta today. I was wondering when and if Blackdown would release their port. I've always found the Blackdown VMs to be of the highest quality, and would really like to use them over Sun's. But I would also like 1.3.1 and 1.4.0 support. I hear that 1.3.1 support is in the works and will be a few days, cool. Any idea when a 1.4 port might be ready?

very small main window
Hi, I just installed the jdk1.3.1 and run one of my program on Redhat 7.1, But I find my program's GUI main window becomes very small. The program was run well on Redhat 6.2.

Hi all, Thanks for your responces. I found the solution for this one. I just shifted functions show and setSize in the code and got the JDialog visible. Original code: /*Code Start*/ JDialog npd=new JDialog(Dialog d,String s); npd.show(); npd.setSize(250,250); /*Code End*/ Changed code: JDialog npd=new JDialog(Dialog d,String s); npd.setSize(250,250); npd.show(); Well I cant make out the reason behind this. Now a real question :Is java 100% platform independant? I know its a foolish question to ask after you have seen results like this. For the second question of applets on windows and Red Hat Linux i am specific about the look and feel of GUI . Is awt,swings applets behaviour dependant on platforms. Is there any such info available form blackdown or anyone else. Thanks and Regards Amol -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

The core Java platform is platform-independent, but... - In any complicated spec, there are always lots of little details that are not specified and might behave differently on different platforms. - Bugs happen, both in Java implementations and in the underlying platform. - Because Linux and Unix support so many different window managers, it's been especially difficult to get all the details of window management to behave consistently everywhere - the problem you reported might be such a case. People used to describe Java as "Write Once, Run Anywhere", but you don't hear that expression used much anymore. A more accurate one is "Write Once, Test Everywhere." Seeing something work differently in Windows than in Linux doesn't necessarily mean the Linux JDK is broken. > For the second question of applets on windows and Red Hat Linux i am > specific about the look and feel of GUI .
