从表格视图处理按钮单击事件 [英] Handle Button click event from Table view
本文介绍了从表格视图处理按钮单击事件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有两列，一列是 Status ，这是我单击的列，另一列是 Approved By ，应在Button动作事件后更新.
我尝试过setOnAction由
I have two columns, one is Status which is the one that I click and the other is Approved By which should update after the Button action event.
I was try setOnAction by
getTableView().getSelectionModel().getSelectedItem().setApprovedby("User");
但这是行不通的.
请帮助我在Button相同行操作事件后如何在批准人列中显示文本.如下图所示
Please help me how to display text into Approved By column after the Button same row action event. It look like as below
//这是状态列的setCellFactory的按钮单元格代码
// Here is button cell code to setCellFactory for Status column
public class Buttoncell implements Callback<TableColumn<thamso, Button>, TableCell<thamso, Button>> {
@Override
public TableCell<thamso, Button> call(TableColumn<thamso, Button> arg) {
TableCell<thamso, Button> cell = new TableCell<thamso, Button>() {
// TODO Auto-generated method stub
protected void updateItem(Button item, boolean empty) {
if (!empty) {
item.setOnAction(e -> {
getTableView().getSelectionModel().getSelectedItem().setApprovedby("User");
item.setText("Approved");;
item.getStyleClass().removeAll("addBobOk, focus");
item.getStyleClass().add("addBobOk");
});
}
setGraphic(item);
}
};
return cell;
}

推荐答案
在大多数情况下，将Node存储在项目类中不是一个好主意.在这种情况下，这不是一个好主意.您将数据的可视表示形式与数据本身混合在一起.
It's not a good idea to store Nodes in the item class in most cases. In this case it's not a good idea. You mix up the visual representation of the data with the data itself.
由于无法观察到approvedby属性，因此不会更新另一列中的单元格.对这个属性使用StringProperty可以忍受TableView可以观察到的属性更改:
The cell in the other column won't be updated, since the approvedby property is not observable. Use a StringProperty for this property to endure changes to the property can be observed by TableView:
public class thamso {
...
private StringProperty approvedby;
//private Button statusaproval;
...
public thamso(String projectid, String model, String drawingname, String partname, int quantity, int spare,
int qtyperset, int no, String material, float weight, String note, String drawing, int rev,
String hyperlink, String importby, String dateimport, String approvedby, String dateapproval) {
...
this.approvedby = new SimpleStringProperty(approvedby);
this.dateapproval = dateapproval;
}
public String getApprovedby() {
return approvedby.get();
}
public void setApprovedby(String approvedby) {
this.approvedby.set(approvedby);
}
public StringProperty approvedbyProperty() {
return this.approvedby;
}
...
}
工程控制器
public class Engineeringcontroller {
...
@FXML
public TableColumn<thamso, String> approvedby;
...
@FXML
private TableColumn<thamso, String> status;
...
@FXML
public void initialize() {
...
approvedby.setCellValueFactory(new PropertyValueFactory<>("approvedby"));
approvedby.setCellFactory(TextFieldTableCell.<thamso>forTableColumn());
...
status.setCellValueFactory(new PropertyValueFactory<>("approvedby"));
status.setCellFactory(new Buttoncell());
...
}
...
}
纽扣电池
public class Buttoncell implements Callback<TableColumn<thamso, String>, TableCell<thamso, String>> {
@Override
public TableCell<thamso, String> call(TableColumn<thamso, String> arg) {
TableCell<thamso, String> cell = new TableCell<thamso, String>() {
private final Button button;
{
button = new Button();
button.setOnAction(evt -> {
thamso item = (thamso) getTableRow().getItem();
item.setApprovedby("User");:
});
}
@Override
protected void updateItem(String item, boolean empty) {
if (empty) {
// remove button
setGraphic(null);
} else {
// set up button based on item
button.getStyleClass().remove("addBobOk");
if (item != null && !item.isEmpty()) {
button.getStyleClass().add("addBobOk");
button.setText("Approved");
} else {
button.setText("pending approval");
}
setGraphic(button);
}
}
};
return cell;
}
}
注意:在上面的代码中，我假设thamso已被接受，前提是有人！= ""批准了它.可以使用例如而是一个布尔属性.
Note: in the code above I assume that a thamso is accepted iff someone != "" has approved it. It's possible to use e.g. a boolean property for this instead.
