changed them over and over, for example I try this one: super(new shell(new Display(),SWT.NONE),SWT.NONE); but the error still the same. how can I Use Design Tab to Design e Customized Composite?

Here is exception from editor log (most probably you can not see it, but it is included into error report). As you can see, WindowBuilder attempted to create Shell to pass it as "parent", but failed by some reason. Probably something is bad with your Eclipse, JVM or Linux. In general this error is not from WindowBuilder. parent ---- org.eclipse.swt.SWTError: No more handles at org.eclipse.swt.SWT.error(Unknown Source) at org.eclipse.swt.SWT.error(Unknown Source) at org.eclipse.swt.SWT.error(Unknown Source) at org.eclipse.swt.widgets.Composite.createHandle(Unknown Source) at org.eclipse.swt.widgets.Shell.createHandle(Unknown Source) at org.eclipse.swt.widgets.Widget.createWidget(Unknown Source) at org.eclipse.swt.widgets.Control.createWidget(Unknown Source) at org.eclipse.swt.widgets.Scrollable.createWidget(Unknown Source) at org.eclipse.swt.widgets.Decorations.createWidget(Unknown Source) at org.eclipse.swt.widgets.Shell.<init>(Unknown Source) at org.eclipse.swt.widgets.Shell.<init>(Unknown Source) at org.eclipse.swt.widgets.Shell.<init>(Unknown Source) at org.eclipse.swt.widgets.Shell.<init>(Unknown Source) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:532) at java.lang.Class.newInstance0(Class.java:372) at java.lang.Class.newInstance(Class.java:325) at org.eclipse.wb.internal.swt.model.widgets.SwtMethodParameterEvaluator.getDefaultShell(SwtMethodParameterEvaluator.java:76)
I would suggest rebooting the OS and making sure you have enough memory assigned to Eclipse. A "No more handles" error is a low memory problem not caused by WindowBuilder.
I think it should be a problem from XULRunner, however I Update it and set env-var corectly. I had faced this problem about rendering html code in swt browser, and finally I have had to change it from SWT.MOZILLA to SWT.WEBKIT. my question is: does windowsbuiler use xulrunner? can I change it to webkit? I add this line to my eclipse.ini : -Dorg.eclipse.swt.browser.UseWebKitGTK=true but nothing changed
WindowBuilder doesn't use Browser (neither Xulrunner nor WebKit) under the hood to edit SWT UI. Why do you think that this is Xulrunner problem? Did you try to re-install Eclipse and WindowBuilder?
I faced this error (org.eclipse.swt.SWTError: No more handles) before, and it was from swt browser. the xulrunner couldn't create a new handle for my application. I switch my program to use Webkit and error disappear. I think when windowsBuilder want to create a shell, eclipse automaticaly wants to create a new handle to show windowsbuilder designe mode, and it use xulrunner to do that.
