i've migrating from swing to swt and while doing so, got this error.
Exception in thread "Thread-0" org.eclipse.swt.SWTException: Invalid thread access
at org.eclipse.swt.SWT.error(
at org.eclipse.swt.SWT.error(
at org.eclipse.swt.SWT.error(
at org.eclipse.swt.widgets.Widget.error(
at org.eclipse.swt.widgets.Widget.checkWidget(
at org.eclipse.swt.widgets.Dialog.checkParent(
at org.eclipse.swt.widgets.Dialog.<init>(
at org.eclipse.swt.widgets.MessageBox.<init>(
at gui.DialogFactory.showError(

all it does is invoke a dialog from a different thread. works fine with swing. what do i do in swt to make it work?
