Java SWT:在写入之前清除表中的所有项目 [英] Java SWT: Clear all items in a table before writing

问题描述

如何在写入所有行之前清除表格?每次点击这段代码，数据都会完全不同:

graphicsMemoryTable.setRedraw(false);整数计数 = 0;for(int i=0; i

作为参考，调用 removeAll() 对我有用，调用 clearAll 没有

解决方案

removeAll() Table 方法将删除表格中的所有元素.这是javadoc;

public void removeAll()

<块引用>

从接收器中移除所有项目.

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

解决方案

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.
