将操作设置为在按钮上执行一次即可执行两项操作 [英] Set Action on button to do two action in one click

问题描述

这里是场景，我有一个主窗口，然后单击一个按钮，它会打开一个弹出窗口.在这个弹出窗口中，我有一个表视图，其中显示了一些数据，并且它有一个名为选择"的按钮.从表格视图中选择数据后，因此当我按下选择按钮时，我希望关闭此弹出窗口，并从中选择的数据显示在主窗口中.

Here is the scenario, I have a main window and I click on one button it opens a pop up window. In this pop window I have table view that have some data display in it, and it have a one button called select. After select the data from table view, so when I push the select button I want this pop window to close and the data I selected from that to appear in my main window.

到目前为止，我唯一能做的就是从弹出窗口中提取数据，我希望它只需单击一下即可关闭

So far only thing I can do is extract the data from pop up window, I want it to close aswell with just one click

private void venueDisplay(String title, String message) {
    Stage window = new Stage();

    //Block events to other windows
    window.initModality(Modality.APPLICATION_MODAL);
    window.setTitle(title);
    window.setMinWidth(400);

    HBox hBox = new HBox();
    hBox.setPadding(new Insets(10,10,10,10));
    hBox.setSpacing(10);
    hBox.setMaxHeight(20);
    hBox.setAlignment(Pos.BOTTOM_CENTER);

    hBox.getChildren().add(selectVenueButton);

    //Display all the available venues to choose for allocation
    VBox layout = new VBox(10);
    venueList = new ListView<>();
    ObservableList<Venue> observableVenue = FXCollections.observableArrayList(model.getVenues());
    venueList.setItems(observableVenue);


    layout.getChildren().addAll(venueList, hBox);

    //Display window and wait for it to be closed before returning
    Scene scene1 = new Scene(layout,300,500);
    window.setScene(scene1);
    window.showAndWait();
}

public void selectButtonHandler(EventHandler<ActionEvent> handler) {
    selectVenueButton.setOnAction(handler);
}

推荐答案

我认为您可以做到:

private Venue venueDisplay(String title, String message) {

    // existing code..

    window.showAndWait();
    return venueList.getSelectionModel().getSelectedItem();
}

，然后您的selectVenueButton只需要关闭窗口:

and then your selectVenueButton just needs to close the window:

selectVenueButton.setOnAction(e -> window.hide());
