I moved from C++ to Java 6 years ago an used “Effective Java” by Bloch, this is a style book which explains in 50 short articles how best to use various java classes and techniques. This is very similar to “Effective C++” by Meyers and “Exceptional C++” by Sutter. If you already know C++ and … Read more
It is thrown because your listener code is called from outside the SWT Display thread. You run code on the display thread like this: Display.getDefault().syncExec(new Runnable() { public void run() { // … } }); or, asynchronously: Display.getDefault().asyncExec(new Runnable() { public void run() { // … } });
I’ve just run into the same problem. I haven’t tried it yet, but I plan to include versions of swt.jar for all platforms and load the correct one dynamically in the start of the main method. UPDATE: It worked. build.xml includes all jars: <zipfileset dir=”/home/aromanov/workspace/foo/lib” includes=”swt_linux_gtk_x86.jar”/> <zipfileset dir=”/home/aromanov/workspace/foo/lib” includes=”swt_macosx_x86.jar”/> <zipfileset dir=”/home/aromanov/workspace/foo/lib” includes=”swt_win32_x86.jar”/> <zipfileset dir=”/home/aromanov/workspace/foo/lib” includes=”swt_linux_gtk_x64.jar”/> … Read more
Most of the times this is a bug in the VM. But it can be caused by any native code (e.g. JNI calls). The hs_err_pidXXX.log file should contain some information about where the problem happened. You can also check the “Heap” section inside the file. Many of the VM bugs are caused by the garbage … Read more
On 64-bit JVM’s you need the 64-bit SWT. Current versions can be downloaded here: http://archive.eclipse.org/eclipse/downloads/drops/R-3.6.1-201009090800/index.php#SWT Note the first two downloads, the first is for x32, the other for x64. Note: Even on 64bit Windows, if you use the 32bit JVM, you still need the 32bit SWT version!
To follow up on pauxu’s answer, I’m using launch4j and NSIS on a project of mine and thought it would be helpful to show just how I’m using them. Here’s what I’m doing for Windows. BTW, I’m creating .app and .dmg for Mac, but haven’t figured out what to do for Linux yet. Project Copies … Read more
I had the same problem, turned out that TeamViewer was causing this. In your TeamViewer go to: Extras → Options → Advanced → QuickConnect button, configure it and disable the show QuickConnect button.
For standard colors (including common colors and default colors used by the operating system) Use Display.getSystemColor(int), and pass in the SWT.COLOR_* constant for the color you want. Display display = Display.getCurrent(); Color blue = display.getSystemColor(SWT.COLOR_BLUE); Color listBackground = display.getSystemColor(SWT.COLOR_LIST_BACKGROUND); Note that you do not need to dispose these colors because SWT created them.
Just package it anywhere in the jar. One thing you have to keep in mind though – before you can use the DLLs you need to actually extract these from the JAR and dump these on the hard disk somewhere otherwise you won’t be able to load these So basically – I did JNI project … Read more
