如何禁用ScrolledForm中的滾動條？

Question

ScrolledForm的滾動條有時會​​導致問題。我遇到了與this guy in EclipseZone Forum相同的問題（這是2005年提出的一個問題，但似乎尚未解決）。

//The scrollbar should only be displayed in the TreeViewer,not the whole form

我來翻過這一問題多次和解決它像這樣：

@Override 
protected void createFormContent(IManagedForm managedForm) { 
    // set the form's body's layout to GridLayout 
    final Composite body = managedForm.getForm().getBody(); 
    body.setLayout(new GridLayout()); 

    // create the composite which should not have the scrollbar and set its layout data 
    // to GridData with width and height hints equal to the size of the form's body 
    final Composite notScrolledComposite = managedForm.getToolkit().createComposite(body); 
    final GridData gdata = GridDataFactory.fillDefaults() 
      .grab(true, true) 
      .hint(body.getClientArea().width, body.getClientArea().height) 
      .create(); 
    notScrolledComposite.setLayoutData(gdata); 

    // add resize listener so the composite's width and height hints are updates when 
    // the form's body resizes 
    body.addControlListener(new ControlAdapter() { 
     @Override 
     public void controlResized(ControlEvent e) { 
      super.controlResized(e); 
      gdata.widthHint = body.getClientArea().width; 
      gdata.heightHint = body.getClientArea().height; 
      notScrolledComposite.layout(true); 
     } 
    }); 
} 

注意的GridLayout形式的身體，然後設置寬度和高度hint到複合材料的GridLayoutData。

另請注意，在更新網格佈局數據和佈局複合體的正文上調整大小偵聽器。

希望它有幫助！
