Eclipse GridData的垂直滚动条 [英] Vertical Scrollbar for Eclipse GridData

问题描述

  import org.eclipse.swt.layout.GridData; 
 import org.eclipse.swt.widgets.List; 
 import org.eclipse.swt.widgets.Composite; 
 import org.eclipse.datatools.connectivity.oda.OdaException; 
 
 public void setupList（Composite parent，List items）throws OdaException {
 
 GridData myGrid = new GridData（GridData.FILL_HORIZONTAL）; 
列出myList = new List（parent，SWT.V_SCROLL）; 
 myList.setLayoutData（myGrid）; 
 myList.setItems（items）; 
 
} 
  

在我的程序中，项目数量超过最大高度的窗口，但没有垂直滚动条出现。

我以为将SWT.V_SCROLL参数传递给列表将创建一个垂直滚动条，但它没有起作用。

我没想到让GridData的列表有一个垂直滚动条？

谢谢。

解决方案

我想出来了。以下行需要更改：

  GridData myGrid = new GridData（GridData.FILL_BOTH）; // FILL_BOTH而不是FILL_HORIZONTAL 
  

I have the following java code in an eclipse application:

import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.widgets.List;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.datatools.connectivity.oda.OdaException;

public void setupList(Composite parent, List items) throws OdaException {

GridData myGrid = new GridData(GridData.FILL_HORIZONTAL);
List myList = new List(parent, SWT.V_SCROLL);
myList.setLayoutData(myGrid);
myList.setItems(items);

}

In my program, the number of items exceeds the maximum height of the window, but no vertical scrollbar appears.

I thought that passing the SWT.V_SCROLL parameter to the list would create a vertical scrollbar, but it didn't work.

What am I missing to make the GridData's List have a vertical scrollbar?

Thanks.

解决方案

I figured it out. The following line needed to change:

GridData myGrid = new GridData(GridData.FILL_BOTH); // FILL_BOTH instead of FILL_HORIZONTAL
