you need ChangeListenerand Clipboardto accomplish your task :)
你需要ChangeListener和Clipboard来完成你的任务:)
Example Code :
示例代码：
Clipboard clipboard = Clipboard.getSystemClipboard();
// add listner to your tableview selecteditemproperty
userTable.getSelectionModel().selectedItemProperty().addListener( new ChangeListener() {
// this method will be called whenever user selected row
@override
public void chnaged(ObservableValue observale, Object oldValue,Object newValue) {
UserClass selectedUser = (UserClass)newValue;
ClipboardContent content = new ClipboardContent();
// make sure you override toString in UserClass
content.putString(selectedUser.toString());
clipboard.setContent(content);
}
});

If i understood you correctly, you want to retrieve the row number of the cell that is currently selected inside a TableView.
如果我理解正确，您想检索当前在 TableView 中选择的单元格的行号。
To do this, request the SelectionModel of the TableView:
为此，请请求 TableView 的 SelectionModel：
// tv is of type TableView
TableView.TableViewSelectionModel selectionModel = tv.getSelectionModel();
ObservableList selectedCells = selectionModel.getSelectedCells();
TablePosition tablePosition = (TablePosition) selectedCells.get(0);
int row = tablePosition.getRow(); // yields the row that the currently selected cell is in

It's still not clear to me what you are trying to do...
我仍然不清楚你想做什么......
However, getting the selected row:
但是，获取所选行：
final Countries selectedCountry = tblCountries.getSelectionModel().getSelectedItem();
If there is a need that another pane becomes visible or another window to show just add an eventhandler to the onclicked property or such?
如果需要另一个窗格可见或另一个窗口显示，只需将事件处理程序添加到 onclicked 属性等？
Is it that what you mean?
你是这个意思吗？
回答by Java Man
tableview.getSelectionModel().selectedItemProperty().addListener(new ChangeListener() {
@Override
public void changed(ObservableValue observableValue, Object oldValue, Object newValue) {
//Check whether item is selected and set value of selected item to Label
if(tableview.getSelectionModel().getSelectedItem() != null)
{
TableViewSelectionModel selectionModel = tableview.getSelectionModel();
ObservableList selectedCells = selectionModel.getSelectedCells();
TablePosition tablePosition = (TablePosition) selectedCells.get(0);
Object val = tablePosition.getTableColumn().getCellData(newValue);
System.out.println("Selected Value" + val);
}
}
});
Using this code you can get the selected value from JAVAFX TABLEVIEW Cell.
使用此代码，您可以从 JAVAFX TABLEVIEW 单元中获取选定的值。
Thanks..
