I wanted to do do lots of methods like: handleGUIEvent(EventChangedX event) handleGUIEvent(EventChangedY event) I am usin...
I just started using eclipse for some personal projects and am finding the transition from IntelliJ (what I use at work) kind of annoying. I hope it's kosher to ask a few different questions in the same thread. Here goes: 1) How do I get "views" (I'm not sure if this is the term. I mean windows such as Project Explorer, Servers, Console...
The text for my buttons is being saved by default as a resource. But then when I click "run," the resource file it loads is the one in the "build" part of the project, not the "source" part. And they aren't the same! For instance, one button I call "create chart". If I do "Clean and Build" it loads correctly, but after that, any changes...

OK - I give up. How can I set width and height of a JFace ListViewer? This should be self-evident but can't seem to find anything and there's no obvious way of doing it looking at the methods of the class. Tried this with no luck: myListViewer.getControl().setSize(1000, 1000); Any help appreciated. ...

Hi, I made a little program to test the System.currentTimeMillis (). And I have a strange result. This is my logs : 1 26-12-09 20:48:21 - [Log] lTime = 1261860501009 2 26-12-09 20:48:21 - [Log] lTime = 1261860501012 3 26-12-09 20:48:21 - [Log] lTime = 1261864899078 4 26-12-09 20:48:21 - [Log] lTime = 1261860501033 5 26-1...
I tried to export a Java program from Eclipse to a .jar file, but I came across a problem. It ran fine, but for some reason it didn't find the text files it was supposed to get data from. If anyone could help with this, I would be very grateful. ...

I am in the process of making a PHP web application. I have a situation that I believe would foster a good time for nested inheritance. Anyway, here is my situation: public class RecurringWeeklyEvent extends RecurringEvent { } public class RecurringEvent extends Event { } It does not seem to me that this would be a bad design practic...
I'm considering opening up a project to create an i-phone virtual machine for android 2.0 (read motorola droid) before i do so i have some questions: Does one already exist that i just missed? Can the the Droid's Arm Cortex A8 down-clocked to 550MHz (thanks wikipedia) handle an I-Phone abstraction layer? Performance wise the best thing...
Okay, so eclipse says my code has errors in it, but there are no red lines. When I try to run my project (Called Game2) it gives me this error: java.lang.NoClassDefFoundError: Game2 Caused by: java.lang.ClassNotFoundException: Game2 at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(N...

I'm developing a lite version for an app on the Android. How can I start an Intent to open the Android Market, preferably with the full version of my app displayed? This is difficult to test on an emulator (which is the closest thing to a device I have), as there seems to be no legal way of installing the Market on it. ...

I've got a executable JAR file. And I've got an Ant build script that compiles and then creates this JAR file. I would like a task to run the JAR file as well, but I've got a command line argument that needs to be passed to the JAR. It's a configuration file. The run target is below <target name="run"> <java jar="build/jar/ShoutGen....
I hear people comment on Java's verbosity (and other languages) as if it were a bad thing, why? To me it makes code easier to understand. Less typing seems like a really trivial argument. ...
Coming from Java background, I find C++'s enums very lame. I wanted to know how to write Java-like enums (the ones in which the enum values are objects, and can have attributes and methods) in C++. As an example, translate the following Java code (a part of it, sufficient to demonstrate the technique) to C++ : public enum Planet { ...
Does this seem correct? I'm trying to port this checksum method from C to Java but the values returned from my Java function are too high. I suspect the way I'm fudging the unsigned int is not correct? char *Generate( char * buffer, long length ) { static char tBuf[4]; long index; unsigned int checksum; for( index ...
