TableViewer中的字段之间的Tab [英] Tab between fields in TableViewer

问题描述

我想做的是能够在表格中的元素之间进行标签。

What I'd like to do is be able to tab between elements in table.

我目前正在创建这样的表。

I currently am creating my table like this.

this.tableViewer = 
            new TableViewer(parent , SWT.FULL_SELECTION);

   tableViewer.setUseHashlookup(true);
        table = tableViewer.getTable();

        GridData gridData = new GridData(GridData.FILL_BOTH);
        gridData.grabExcessVerticalSpace = true;
        table.setLayoutData(gridData);

        table.setLinesVisible(true);
        table.setHeaderVisible(true);

        ...

   /** Create the Cell Editor Array - will hold all columns **/
        editors = new CellEditor[table.getColumnCount()];
        /** Cell Editor Row 1 **/


  /** Set the column properties **/
        tableViewer.setColumnProperties(columnNames);

        /** Assign the cell editors to the viewer **/
        tableViewer.setCellEditors(editors);

        /** Set the cell modifier for the viewer **/
        tableViewer.setCellModifier(new MyCellModifier(this));
        //Create the Table Viewer

        /** Table Viewer Content and Label Provider **/
        tableViewer.setContentProvider(new MyContentProvider(this));
        tableViewer.setLabelProvider(new MyLabelProvider());

但我不知道如何设置表格。其他的一切都可以在编辑列，显示数据等方面工作。刚刚停留在最后一部分。

But I'm not sure how to set up the tabulation. Everything else works as far as editing columns, showing data, etc. Just stuck on this last part.

如果我错过了明显的文档或javadocs - 我的道歉甚至指向那些将是伟大的。

If I've missed obvious documentation or javadocs - my apologies and even pointing to those would be great.

推荐答案

我认为默认选项卡不会从单元格跳转到单元格的swt表。而是遍历到下一个控件。所以你还需要告诉它不要在tab被按下的时候运行

I think by default tab does not jump from cell to cell in an swt table. Instead it traverses to the next control. So you'll also need to tell it not to traverse when tab is pressed

KeyListener keyListener = new KeyLisener()
{
    public void keyPressed(KeyEvent evt)
    {
        if (evt.keyCode == SWT.TAB)
        {
            // There are numerous setSelection methods.  I'll leave this to you. 
            tableViewer.getTable().setSelection(...)
        }
    }

    public void keyReleased(KeyEvent evt){}
}

TraverseListener traverseListener = new TraverseListener()
{
    public void keyTraversed(TraverseEvent evt)
    {
        if (evt.keyCode == SWT.TAB)
            evt.doit = false;
    }
}

tableViewer.getTable().addKeyListener(keyListener);
tableViewer.getTable().addTraverseListener(traverseListener);

另外，正如derBiggi所建议的，侦听器需要添加到Table对象中，而不是TableViewer。

Also, as derBiggi suggested, the listeners need to be added to the Table object, not the TableViewer.
