我正在使用来自ControlsFX(v8.40.12)的SpreadsheetView控件进行一些测试,我无法将任何其他类型的对象添加到除文本之外的单元格中。
代码有问题,或者我错过了什么? 有人能告诉我我该怎么做?
我正在使用SpreadsheetCellBase,SetGraphic和setCellValue。
有些评论是葡萄牙语,抱歉!
非常感谢。

有一个类似的帖子,但它没有给我一个答案: How to change text in cells (SpreadsheetView by ControlsFX)?
答案 0 :(得分:1)
首先,您的代码未编译,因为我们错过了图片和css样式表。链接代码时,请尝试直接使用。
关于您的问题,您正在创建新的SpreadsheetCells,但您永远不会将它们添加到网格中!
SpreadsheetCellBase cell = new SpreadsheetCellBase(10, 4, 1, 1);
cell.setItem(null);
cell.setGraphic(new DatePicker());
除非从未将单元格赋予网格,否则这是绝对正确的。您正在寻找的单元格已添加到上面的循环中。所以你需要做的就是访问它,并像这样设置datePicker:
linhas.get(10).get(4).setGraphic(new DatePicker());
然后它会起作用。
另外,最好使用SpreadsheetCellType和SpreadsheetCell而不是直接实例化SpreadsheetCellBase:
for (int linha = 0; linha < grelha.getRowCount(); linha++)
{
celulas = FXCollections.<SpreadsheetCell>observableArrayList();
for (int coluna = 0; coluna < grelha.getColumnCount(); coluna++)
{
celula = SpreadsheetCellType.STRING.createCell(linha, coluna, 1, 1, "---");
// celula.setItem("---");
celulas.add(celula);
}
linhas.add(celulas);
}
另请注意,我们有一个ControlsFX Google群组,您可以在其中提出问题:https://groups.google.com/forum/#!forum/controlsfx-dev 我们在那里得到通知..所以通常响应更快;)
