如何禁用ScrolledForm中的滚动条？

Question

ScrolledForm的滚动条有时会​​导致问题。我遇到了与this guy in EclipseZone Forum相同的问题（这是2005年提出的一个问题，但似乎尚未解决）。

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

我来翻过这一问题多次和解决它像这样：

@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形式的身体，然后设置宽度和高度hint到复合材料的GridLayoutData。

另请注意，在更新网格布局数据和布局复合体的正文上调整大小侦听器。

希望它有帮助！
