My issue is that I need to use Java code and Python code, each generating a window, Java still being the main process.
What I need is to link those two windows together. When I resize one, it resize the other, and same behavior when moving one, minimizing,...
I tried looking at the documentation or other solution on the Internet but I found nothing near my issue.
Will I need to implement a whole solution for it (listeners on both window to get size and resize the other, or position,...) or is there something I have been missing ?

I'm working on a Java project (for those curious, it's a Rcon and Query client for Minecraft servers) and I'm trying to create a GUI. I'm using Eclipse Windowbuilder, and I'm trying to make the program window dynamic (in other words, when the window is resized, everything else moves and scales to fit), but none of the layouts seem to do that (which defeats the purpose of the layout, doesn't it). It's worth mentioning that I'm putting four groups on the screen, which will contain other things and should take up all available space. I would put the code here, but there's nothing besides the default application framework generated by Eclipse. So, what layout do I use for dynamic resizing and such? Or am I missing something stupid?
(P.S. I've tried GridLayout, FormLayout, and many others. They didn't work.)
The following is for Eclipse Windowbuilder users.
For this to work (assuming GridLayout is used) you must set several properties for every single thing in the GridLayout:
grabExcessHorizontalSpace should be true (check the box)
grabExcessVerticalSpace should also be true (again, check the box)
horizontalAlignment should be set to FILL (selected from drop-down)
verticalAlignment should also be set to FILL (also selected from drop-down)
Thanks to greg-449 for giving me this link, which solved the problem.
What I am trying to accomplish is to select an area on the screen with the mouse (outside of the may frame) and get the resulting region coordinates using Sikuli.
The code that should do this looks is below:
Screen screen = Screen.getPrimaryScreen();
Region region = screen.selectRegion("Select the area.");
What happens is that the cursor turns into a selector cross (the ones you usually see when you expect this function), but I can't select the area and actually the only way I can get back from the application is by killing it. Not too many examples I have found so I am asking for help here.
How can I make this work?
Also one other question:
I have downloaded the following script version:
Sikuli-IDE-1.0.0-Win64.zip
This means if I want to create a crossplatform solution I have to include like 6 jars? I have found a more universal Java API it seems (that is what it is called actually):
https://code.google.com/p/sikuli-api/
With all required supported OS but I can't find a single example on what I am trying to do that is similar to the little code snippet I pasted here. The sikuli script I am using now and this Sikuli API (apparently not the same) seems to be just different enough to amke this difficult.
Any suggestions? Thanks a lot in advance.
As it turns out, this only happens if I put this functionality on a Swing button's actionhandler. I have reported the bug to Sikuli and it will be probably fixed in the next release.
As I run Java programs (like DbVisualizer and OpenProj) on my computer, some UI components like buttons, images, check boxes, scrollbars, etc. show as blank boxes. Not rarely some of these components first appear normally when you open the program and then go blank as you mouse over them.
I have already updated JRE and video drivers and also tweaked JAVA_OPTS with -Dsun.java2d.noddraw=true;-Dsun.java2d.d3d=false;, as recommended in Java forums, but none of these proposed solutions have worked so far.
I don't believe this is an OS specific issue, since I checked some other PCs with the exact same configuration of OS (Windows Vista) and hardware and many of them don't present that problem.
A screenshot of this situation can be seen here:
Any ideas?
Those JAVA_OPTS must be separated by spaces and not semi-colons!
Connect to the application with jVisualVM and verify that the "JVM Arguments" section contains all your desired options.
While using windows basic theme I would often find numerous graphical glitches. Moving a window would create a trail behind itself over background windows and UI controls at times would not appear until moused over.
As already suggested, try using the windows aero theme and just turn off transparency if you don't like the aero look.
This does seem more like a graphics driver issue. Note how things that are missing are images (icons, checkboxes) which are drawn by transferring the bitmap data directly to the graphic card. The sun.java2d.noddraw=false and sun.java2d.d3d=false are more of a hacks in this case, really.
What I would do is:
check if I am using the latest version of Java (wouldn't hurt to switch to a 64-bit java if you are using a 64-bit system)
check your graphics drivers, make sure they are the latest version
check Windows service packs
Also try using changing the Look and feel; maybe this will help.
I suspect that disabling DirectDraw will fix this and your attempt to disable it was unsuccessful.
As noted by Ryan, the options appear to be formatted incorrectly. Remove the semicolons and put a space between, or better still, only use sun.java2d.d3d=false. The sun.java2d.noddraw flag was obsoleted Java SE6u10 and setting to true now has the same effect as setting sun.java2d.d3d=false. There is no need to set both.
The effect of the incorrect formatting can be seen in the code below:
public class WrongArgs {
public static void main(String[] args) {
System.out.println("sun.java2d.noddraw: " + System.getProperty("sun.java2d.noddraw"));
System.out.println("sun.java2d.d3d: " + System.getProperty("sun.java2d.d3d"));
}
}
Running this code with args: "-Dsun.java2d.noddraw=true;-Dsun.java2d.d3d=false;" produces:
sun.java2d.noddraw: true;-Dsun.java2d.d3d=false;
sun.java2d.d3d: null
Running with args "-Dsun.java2d.noddraw=true -Dsun.java2d.d3d=false"
sun.java2d.noddraw: true
sun.java2d.d3d: false
I am interested in knowing Debugging setup that'll allow a programmer to be most productive. Assuming knowledge about debugging in general.
I am mainly interested in knowing how and where you place different windows like the variables window, code window, the stack. Also possibly the relative size of different windows.
I'd prefer if there are screenshots attached and a description of why the setup works for you or one that is efficient.
I mainly use Eclipse and Netbeans.
Most productive? That's going to vary greatly from person to person. You shouldn't focus on what works best for other people or details like precise window placement... figure out what works best for you with some trial and error.
For me, multiple monitors are important. I keep code and tools (Eclipse, SQL manager, etc) open on one, and use the other for the console and the running program (whatever it may be: website, windowed application, etc).
First you have to know how to use the debugger really well and then after that the placement of windows is just frivolous detail, for the most part. It will just fall into place without having to mimic other people's comfort level with the tools.
It sounds like you're looking for a static setup but likely you will show/hide windows depending on what you're debugging and size them to different situations. At least that's what I do. So I would post many screenshots and they'd all look different.
"I'd prefer if there are screenshots attached and a description of why the setup works for you. "
You're exactly right knowing it works for the other person.
In addition to what others have said, one thing that I do with respect to variable windows - Visual Studio gives you 4 different watch windows. I usually put them all into a single tabbed window, and each tab will represent a different programming context. For example, tab 1 will list variables that I usually need to look at when dealing with area A, tab 2 has variables for area B and so on.
Doing this, I find that the watch windows don't get over cluttered and I spend less time setting up variables
I extend org.eclipse.swt.widgets.Composite and create many widgets on it, (labels, table, text etc). The problem I am facing is that the labels' text is getting truncated on linux while it appears fine on windows. When I change the linux's font to gothic the truncation is little less but still there. Is there way to homogenize the windows and linux display. What could be the best font to use in linux in such a case.
More likely it is related to this eclipse bug which I just lobbied to have re-opened: https://bugs.eclipse.org/bugs/show_bug.cgi?id=151322
It sounds like you are using absolute positioning instead of dynamic layouts. (If this isn't the case, perhaps you could post code demonstrating the problem). Using a dynamic layout should ensure that controls are resized to accommodate their contents. (They're also great if you ever translate a product, because then you don't have to rejig every dialog for every language.)
To complete McDowel's answer, there is also a bug related to the way Linux check for wrapping label:
It is fixed since 3.4M7.
Even though it may not be related to your case, it would be useful to know which version of eclipse you are using and if you can reproduce your bug with the latest ones (like a 3.5M6)
