JavaFX 2: How to focus a table row programmatically?
提问by brnzn
I am trying to select/focus a row of a TableViewprogrammatically.
我正在尝试以TableView编程方式选择/聚焦一行。
I can select a row, but it is not getting rendered as focused(not highlighted). I have tried many combinations of the code below, but nothing seems to work.
我可以选择一行，但它没有被渲染为焦点（未突出显示）。我尝试了以下代码的多种组合，但似乎没有任何效果。
table.getSelectionModel().select(0);
table.focusModelProperty().get().focus(new TablePosition(table, 0, column));
table.requestFocus();
Is it possible to highlight a row programmatically?
是否可以以编程方式突出显示一行？
I am using JavaFX 2.2.21

Try putting your request for table focus first and then wrapping the whole thing in a runLater.
尝试首先将您对表格焦点的请求放在一个runLater.
Platform.runLater(new Runnable()
{
@Override
public void run()
{
table.requestFocus();
table.getSelectionModel().select(0);
table.getFocusModel().focus(0);
}
});

table.getSelectionModel().select(0);works for me. Maybe the problem is in your css?
table.getSelectionModel().select(0);为我工作。也许问题出在你的css中？

I have two components: a ListViewand a TableView. When an item in the ListViewis clicked, I want the focus and selection to move to the TableViewand render the selected component in the TableView. To accomplish this, I did it with:
我有两个组件： aListView和 a TableView。ListView单击 中的项目时，我希望焦点和选择移动到TableView并在TableView. 为了做到这一点，我做到了：
void listViewClickHandler(MouseEvent e){
A a = listView.getSelectionModel().getSelectedItem();
if(a != null){
// some stuff
// move focus & selection to TableView
table.getSelectionModel().clearSelection(); // We don't want repeated selections
table.requestFocus(); // Get the focus
table.getSelectionModel().selectFirst(); // select first item in TableView model
table.getFocusModel().focus(0); // set the focus on the first element
tableClickHandler(null); // render the selected item in the TableView
}
void tableClickHandler(MouseEvent e){
B b = table.getSelectionModel().getSelectedItem();
render(b);
}

table.getFocusModel().focus(0);is not needed, but I would also add scrollToas well.
table.getFocusModel().focus(0);不需要，但我也会补充scrollTo。
Java 8:
爪哇 8：
Platform.runLater(() ->
{
table.requestFocus();
table.getSelectionModel().select(0);
table.scrollTo(0);
});
Java 7:

Platform.runLater(new Runnable()
{
@Override
public void run()
{
table.requestFocus();
table.getSelectionModel().select(0);
table.scrollTo(0);
}
});
