Java SWT: Clear all items in a table before writing

问题

How do I clear a table before writing all the rows? The data will be completely different every time I hit this code:

graphicsMemoryTable.setRedraw(false);
int count = 0;
for(int i=0; i<graphicsMemory.size() && count<1000; i+=8,count++)
{
    TableItem item = new TableItem(graphicsMemoryTable, SWT.NONE);
    item.setText(graphicsMemory.get(i).toString());
    item.setText(1,graphicsMemory.get(i+1).toString());
    item.setText(2,graphicsMemory.get(i+2).toString());
    item.setText(3,graphicsMemory.get(i+3).toString());
    item.setText(4,graphicsMemory.get(i+4).toString());
    item.setText(5,graphicsMemory.get(i+5).toString());
    item.setText(6,graphicsMemory.get(i+6).toString());
    item.setText(7,graphicsMemory.get(i+7).toString());
}
graphicsMemoryTable.setRedraw(true);

EDIT: For reference, calling removeAll() worked for me, calling clearAll did not

回答1:

removeAll() method of Table will remove all elements in the table. Here is the javadoc;

public void removeAll()

Removes all of the items from the receiver.

回答2:

You can use table.clearAll();

Clears all the items in the receiver. The text, icon and other attributes of the items are set to their default values. If the table was created with the SWT.VIRTUAL style, these attributes are requested again as needed.
