我们说我的情况是这样的:我有一个TableView
(tableAuthors),其中有两个TableColumns
(ID和姓名)。
这是TableView
使用的AuthorProps POJO:
import javafx.beans.property.SimpleIntegerProperty;
import javafx.beans.property.SimpleStringProperty;
public class AuthorProps {
private final SimpleIntegerProperty authorsId;
private final SimpleStringProperty authorsName;
public AuthorProps(int authorsId, String authorsName) {
this.authorsId = new SimpleIntegerProperty(authorsId);
this.authorsName = new SimpleStringProperty( authorsName);
}
public int getAuthorsId() {
return authorsId.get();
}
public SimpleIntegerProperty authorsIdProperty() {
return authorsId;
}
public void setAuthorsId(int authorsId) {
this.authorsId.set(authorsId);
}
public String getAuthorsName() {
return authorsName.get();
}
public SimpleStringProperty authorsNameProperty() {
return authorsName;
}
public void setAuthorsName(String authorsName) {
this.authorsName.set(authorsName);
}
}
让我们说我有两个TextFields
(txtId和txtName)。现在,我想将表格单元格中的值绑定到TextFields
。
tableAuthors.getSelectionModel()
.selectedItemProperty()
.addListener((observableValue, authorProps, authorProps2) -> {
//This works:
txtName.textProperty().bindBidirectional(authorProps2.authorsNameProperty());
//This doesn't work:
txtId.textProperty().bindBidirectional(authorProps2.authorsIdProperty());
});
我可以将姓名TableColumn
绑定到txtName TextField
,因为authorsNameProperty
是SimpleStringProperty
,但我无法将ID TableColumn
绑定到txtId { {1}}因为TextField
是authorsIdProperty
。我的问题是:如何将txtId绑定到Id SimpleIntegerProperty
?
P.S。如果有必要,我可以提供工作示例。
答案 0 :(得分:17)
尝试:
txtId.textProperty().bindBidirectional(authorProps2.authorsIdProperty(), new NumberStringConverter());
