如何确定javafx tablecell引用的数据类型(String,Integer,Double等)。例如。我有一个自定义单元工厂,分配给Javafx控制器中的字段,如下所示:
CustomCellFactory<Damageloop, Date> damageLoopWorkshopDueDateFactory = new CustomCellFactory ("colDamageLoopWorkshopDueDate", false);
这会调用以下类......
public class CustomCellFactory<S, T> implements Callback<TableColumn<S, T>, TableCell<S, T>> {
String colname;
boolean editable;
public CustomCellFactory (String colname, boolean editable) {
this.colname = colname;
this.editable = editable;
}
@Override
public TableCell<S, T> call(TableColumn<S, T> arg) {
TableCell<S, T> cell;
if (editable == true) {
cell = new TableCellEditable<>(colname);
} else {
cell = new TableCellCustom<>(colname);
}
return cell;
}
}
反过来调用以下类......
public class TableCellCustom <S, T> extends TableCell<S, T> {
String colname;
public TableCellCustom (String colname) {
this.colname = colname;
}
@Override
protected void updateItem(T item, boolean empty) {
super.updateItem(item, empty);
if (empty || item == null) {
setText(null);
setGraphic(null);
} else {
setConditionalFormatting(this,item);
}
}
public void setConditionalFormatting (TableCell<S,T> cell, T item) {
//perform specific cell formatting....
}
}
并且想要确定TableCellCustom级别的单元格的数据类型(即创建CustomCellFactory时传递的初始参数,在本例中为Date),因此可以基于此执行特定操作。我试过......
super.itemProperty().getName()
这将返回与该单元格相关的一大堆信息,如下所示:
ObjectProperty [bean: EditableTableCell[id=colDamageLoopWorkshopDueDate, styleClass=cell indexed-cell table-cell table-column]'17/01/2016', name: item, value: 2016-01-17]
但是没有引用cell数据类型。
