How to make Hyperlink TableColumn in TableView editable - javafx

Question

TableColumn<ComponentObject, Hyperlink> template_id = new TableColumn<ComponentObject, Hyperlink>("Template Id");
template_id.setCellValueFactory(
new PropertyValueFactory<ComponentObject, Hyperlink>("template"));
template_id.setCellFactory(TextFieldTableCell.forTableColumn());
template_id.setOnEditCommit(
new EventHandler<CellEditEvent<ComponentObject, Hyperlink>>() {
#Override
public void handle(CellEditEvent<ComponentObject, Hyperlink> t) {
((ComponentObject) t.getTableView().getItems().get(
t.getTablePosition().getRow())
).setTemplate((javafx.scene.control.Hyperlink) t.getNewValue());
}
}
);
Here setCellFactory is giving error as
"
The method setCellFactory(Callback<TableColumn<ComponentObject,Hyperlink>,TableCell<ComponentObject,Hyperlink>>) in
the type TableColumn<ComponentObject,Hyperlink> is not applicable for the arguments
(Callback<TableColumn<Object,String>,TableCell<Object,String>>)
"
How to solve this? I want to make template_id column editable..but note that it is hyperlink..

Answer 1

The quick and dirty way is to specify a stringConverter for the TextFieldTableCell:
StringConverter<Hyperlink> converter = new StringConverter<Hyperlink>() {
#Override
public Hyperlink fromString(String string) {
return new Hyperlink(string);
}
#Override
public String toString(Hyperlink hyperlink) {
return hyperlink.getText();
}
}
template_id.setCellFactory(TextFieldTableCell.forTableColumn(converter));
In general, though, it is a very bad idea to represent your data with UI nodes, which is what you are doing by making the column type a Hyperlink. Strange things may happen here. It would be better to make the data type String, and to implement your own TableCell that showed a Hyperlink when not in editing mode, and a TextField when in editing mode.
