TableView 单元格请求焦点
TableView cell request Focus
我是 JavaFX 新手,遇到以下问题:
我在 BorderPane 中有一个表视图。我希望它在加载时专注于最后一个 row/1st 列。我尝试了以下方法:
- 请求焦点()
- 滚动到()
- focusModel.focus()
- selectionModel.select()
结果是我想要的单元格确实是蓝色的(就像它被选中一样)但第一个单元格有蓝色边框。因此,当我尝试使用箭头键时,所选单元格会移动到第一行。
顺便说一句,我正在使用 TornadoFX。
有什么想法吗?
提前致谢!

// Scroll to and focus on the last cell on startup
if (initialFocus) {

requestFocus()
scrollTo(lastRow)
focusModel.focus(lastRow)
selectionModel.select(lastRow)
initialFocus = false
}
onEditCommit {entry ->
// Update the list
mController.updateCashEntryList(entry)
// Move to the next cell
requestFocus()
focusModel.focusRightCell()
@Suppress("UNCHECKED_CAST")
selectionModel.select(focusModel.focusedCell.row, focusModel.focusedCell.tableColumn as TableColumn<CashEntry, *>)
}
enableCellEditing()
// Enable edit on key typed
addEventHandler(KeyEvent.KEY_PRESSED) {keyEvent ->
if (keyEvent.code.isDigitKey || keyEvent.code.isLetterKey) {
if (editingCell == null) {
val currentSelectedCell = selectedCell
if (currentSelectedCell != null && currentSelectedCell.tableColumn.isEditable) {
edit(currentSelectedCell.row, currentSelectedCell.tableColumn)
}
}
}
}
}
// Add the table to the view
mainView.root.center = cashTable
cashTable.tableMenuButtonVisibleProperty()
// Ensure no other node can get focus
cashTable.focusedProperty().onChange {
val focusOwner = currentStage?.scene?.focusOwnerProperty()?.value
// Check if the focus owner is the table or a cell
if (focusOwner !is TableView<*> && focusOwner !is TextField) {
cashTable.requestFocus()
}
}
}
}
你应该使用
Platform.runLater(() -> {
requestFocus();
scrollTo(lastRow);
...
});
更新 GUI。
