I know how to deal with a mouse click event like so:
Code:
But was happens when I am dealing with mouse dragging? Will my implementation of mouseDragged() get called for every pixel moved? So I just getX() and getY() like with a mouse click?
Also, in order to know when mouse dragging stops and starts, do I also have to put code in mousePressed and mouseReleased?
So, when I program my Java applet I am expected to use an event based model, where I run functions in response to mouse clicks and so forth, and I am supposed to return quickly so that the applet can continue looping. But what if I want certain functions to run by themselves on a regular schedule (like every 200 ms or so) without blocking mouse events, repaints, and so forth?
I looked at the source code of one Java applet I found, and it accomplished this by creating extra threads. I was wondering if creating extra threads was the only way to accomplish that, or if there was some more proper way to do it built into the Applet somehow.

I am using Ubuntu 8.10. All the java programs run perfectly fine in Geany. But when I try to run java applets in web browsers it did not run. I have tried running it in Opera and FireFox. I have written a simple program which display "hello world" in browsers. When I refresh the page it displays the text for about 2 or 3 seconds and after that it disappears.
Are there any other ways to run java applets?
I always have trouble with java applets in Firefox, any time I open one the whole browser just seems to lock up. Any pointers for making them run properly? I'm running Ubuntu 10.04 and I have the IcedTea plugin.

(For comparison, the temp usually stays at 45.0C if I do all this)
Finally, I decided to check htop, and I found IcedTea Plugin at the top with 99% CPU usage. This is used to run embedded Java applets (Java, not Javascript). Curiously, no Java applets were running at that time.Now skip ahead an hour to when I finally discover that the IcedTea Plugin was left over from earlier because it didn't stop running when it was supposed to. Looking online, I see several complaints about Java being very taxing on the CPU in Ubuntu, but I don't see anything about Java applets continuing to run after they're gone.
Can anyone who has Java installed confirm that this happens on their system?
1. Open htop. Search for "icedtea" to make sure it isn't already running. Then click on "CPU%" to sort the list.
2. Open this page in Firefox: www.java.com/en/download/help/testvm.xml
3. Check htop. Is IcedTea climbing to the top? (if you have Java, it likely will, because this is a common issue)
4. Navigate off of the Java.com page by closing the tab or clicking Back.
5. Here's what I want to know. Check htop again. Is IcedTea still there?
6. Restart Firefox to get rid of IcedTea.
I'm using Iceweasel on Debian, and my java applets won't work. They used to work fine so I don't understand what happened to them. I installed the latest java jre from Sun and it made no difference. Java plugin seems to work (at least the javascript part) but it can't seem to download applet's. I tried running one locally (ran on of the example applet that came with the Sun jdk, but they won't work on the web) the java console pops up with these errors.

My sound is otherwise working fine, but for some reason i'm not getting any sound when running java applets. This issue is very important to me, i would -really- like to get the sound back on this applet.it's a java runtime environment applet, running in embedded in firefox. Somehow, the systems isn't detecting it as a application outputting sound.
i tried uninstalling the sound manager application via synaptic, selected the 'completely remove' option, and wound up uninstalling essentially the entire OS last weekend. i'd like to not repeat that mishap, as i lost all my data.

I have a Logitech Media Play mouse with many buttons. I'm using xbindkeys to create some shortcuts to programs e.g. firefox, gnome-terminal--these work wonderful. What I cannot figure out is how to get the buttons to work for the media player(Ubuntu>System>Keyboard Shortcuts>Sound). I set shortcuts using my win key and letters, hoping to use xbindkeys to send out a keystroke. I have tried to use xmacro but to no avail. xdotool was not helpful, I think it may be outdated(desktop/workspace functions did not work).
My preferred option would be to get mouse events to keystrokes working with xbindkeys and program x(x being whatever works); however, just getting my media buttons to interact with the media play is my ultimate goal.

View 4 Replies View RelatedThe following script will work when I type the path to the file I want to checksum, but not when I drag the file to the terminal because the linux terminal (unlike the Mac) automatically puts quotes around the file path, which causes an error. (Clarification: am referring to gnome-terminal. Thanks, GrapefruiTgirl.) I did not find anything in gconf-editor or anywhere else to alter this behaviour, and my post in Launchpad is unanswered so far. (the script in itself is not very useful, I just stumbled upon this error when experimenting with bash).
So, is there a workaround for stripping the quotes from the input, or can I configure the terminal to not quote the input when I drag a file into it (which I would prefer?)

Groovy is an object-oriented programming language for the Java platform. I do not have experience in Java, only perl and shell scripts. Recently I have been asked to maintain a software written in groovy (also to make enhancements). So can I learn groovy without knowing java language. or isit I have to learn java before venturing into groovy.
