问题 I'm trying to show a simple window in SWT.

问题 I have got a CheckboxTableViewer inside a ScrolledComposite. I have to enable or disable all the tableItems based upon the another checkBox button. To do this, I am using CheckboxTableViewer.getTable().setEnabled(false). In the above case, the ScrolledComposite is also disabling along with the table. But I want the scroll behaviour to work as-usual even when CheckboxTableViewer is disabled (all the items in the able are disabled). 回答1: It's not possible to make the table control show

问题 I know that JavaFX 2.2 provides FXCanvas for embedding new JavaFX components into existing SWT Composites. Is it possible to do it the other way around? My motivation for trying this, is that there are currently some components missing in JavaFX. For example a TreeTable. I want to implement my application in JavaFX, use SWT as a fallback for missing components, and migrate those to JavaFX as soon they are ready. 回答1: no - you can not embedd heavy weight (=SWT) into a lightweight container (
