Bug 153398 Invalid thread access in Snippet133
Running SWT Snippet 133 (print text to printer) throws this exception: Exception in thread "Printing" org.eclipse.swt.SWTException: Invalid thread access at org.eclipse.swt.SWT.error(SWT.java:3374) at org.eclipse.swt.SWT.error(SWT.java:3297) at org.eclipse.swt.SWT.error(SWT.java:3268) at org.eclipse.swt.widgets.Widget.error(Widget.java:435) at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:331) at org.eclipse.swt.widgets.Control.getFont(Control.java:939) at org.eclipse.swt.snippets.Snippet133.print(Snippet133.java:230) at org.eclipse.swt.snippets.Snippet133$7.run(Snippet133.java:204) It works if you patch the line: printingThread.start(); with this: display.syncExec(printingThread);
