以编程方式滚动NatTable [英] Scroll NatTable programmatically
问题描述
有关stackoverflow的第一个问题；-)
First question on stackoverflow ;-)
与此处类似的问题，只有我正在尝试滚动
Similar question to here, only I am trying to scroll a NAT-Table programmatically. I can neither show a selected Item, nor set a value to the Scrollbar itself (via getHorizontalBar or similar).
据我所见，互联网没有任何答案，针对其他swt控件的建议解决方案似乎并不适用...
The internet wields no answers, as far as I could see, and solutions suggested for other swt controls do not seem to apply...
推荐答案
这取决于您要实现的目标.您是要选择一个单元格并将其移入视口，还是只是想将单元格移至视口而不进行选择?
That depends on what you are trying to achieve. Do you want to select a cell and move it into the viewport, or do you simply want to move cells into the viewport without selection?
要简单地将单元格移入视口，您应该尝试使用相应的命令来实现此目的:
For simply moving cells into the viewport you should try the corresponding commands to achieve this:
- ShowRowInViewportCommand
- ShowColumnInViewportCommand
-
ShowCellInViewportCommand
- ShowRowInViewportCommand
- ShowColumnInViewportCommand
ShowCellInViewportCommand
natTable.doCommand(new ShowRowInViewportCommand(gridLayer.getBodyLayer()，50));
natTable.doCommand(new ShowRowInViewportCommand(gridLayer.getBodyLayer(), 50));
要实现选择并将行移动到视口中，可以使用相应的选择命令:
To achieve selection and moving a row into the viewport, you could use the corresponding selection commands:
- SelectRowsCommand
- SelectColumnCommand
-
SelectCellCommand
- SelectRowsCommand
- SelectColumnCommand
SelectCellCommand
natTable.doCommand(new SelectRowsCommand(gridLayer.getBodyLayer()，0，50，false，false));
natTable.doCommand(new SelectRowsCommand(gridLayer.getBodyLayer(), 0, 50, false, false));
请注意，您需要考虑位置/索引转换，这意味着上面的语句将由于列标题而选择网格中的51行.
Note that you need to consider the position/index transformations, which means the above statement will select the 51 row in the grid because of the column header.
