Question

我需要在单元格中填充数据库中的文本，但是当单元格已满时，文本应该在下一个单元格中继续，向下。

我有一个想法是如何实现它的：

 Text theText = new Text(jFXTextFieldSearch.getText());
    theText.setFont(jFXTextFieldSearch.getFont());
    double width = theText.getBoundsInLocal().getWidth();
    System.out.println(width);

这种方法有多好还是有另一种方法可以做到这一点？数据库足够大，有50页的表格。附：对不起我的坏工程。（

试试这个：

@FXML
private TableView<String> table;

@FXML
private TableColumn<String, String> column;

...

String string =
        "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt " +
        "ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco " +
        "laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in " +
        "voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat " +
        "non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.";

AttributedString attributedString = new AttributedString(string);
attributedString.addAttribute(TextAttribute.FONT, new Font("Arial", Font.BOLD, 16));

AttributedCharacterIterator iterator = attributedString.getIterator();
FontRenderContext frc = new FontRenderContext(new AffineTransform(), true, true);
LineBreakMeasurer measurer = new LineBreakMeasurer(iterator, frc);

ObservableList<String> list = FXCollections.observableArrayList();
while (measurer.getPosition() < iterator.getEndIndex()) {
    TextLayout layout = measurer.nextLayout((float) column.getWidth());
    list.add(string.substring(measurer.getPosition() - layout.getCharacterCount(), measurer.getPosition()));
}

table.setItems(list);

要提交给attributedString的字体应与用于在所需列中呈现的字体相同。

如何将文本换行到tableview组件中的下一个单元格？
