我是新来的SpreadSheet功能ControlsFx Api。我想打开Dialog在Javafx的SpreadsheetView的Spreadsheetcell的右键点击。任何帮助是极大的赞赏。

Answer 1

这是代码，你可以关闭标准的文本菜单和工具自己的处理程序与Dialog，在这个例子中TextInputDialog：

SpreadsheetView spreadsheetView = new SpreadsheetView(); 
    //off the standard ContextMenu 
    spreadsheetView.setContextMenu(null); 
    //set own handler for right click with Dialog 
    spreadsheetView.setOnContextMenuRequested(new EventHandler<ContextMenuEvent>() { 
     @Override public void handle(ContextMenuEvent event) { 
     CellView cellView = (CellView) event.getTarget(); 
     TextInputDialog dialog = new TextInputDialog(cellView.getText()); 
     Optional<String> result = dialog.showAndWait(); 
     if (result.isPresent()){ 
      System.out.println(cellView.getText()); 
     } 
     } 
    }); 

我不知道很好这个库，但它的作品好。 实例它的工作原理：

我的程序：

public class MainController extends Application { 

    public static void main(String[] args) { 
    launch(args); 
    } 

    @Override public void start(Stage primaryStage) throws Exception { 


    SpreadsheetView spreadsheetView = new SpreadsheetView(); 
    //off the standard ContextMenu 
    spreadsheetView.setContextMenu(null); 
    //set own handler for right click with Dialog 
    spreadsheetView.setOnContextMenuRequested(new EventHandler<ContextMenuEvent>() { 
     @Override public void handle(ContextMenuEvent event) { 
     CellView cellView = (CellView) event.getTarget(); 
     TextInputDialog dialog = new TextInputDialog(cellView.getText()); 
     Optional<String> result = dialog.showAndWait(); 
     if (result.isPresent()) { 
      System.out.println(cellView.getText()); 
     } 
     } 
    }); 

    HBox hBox = new HBox(); 
    hBox.getChildren().add(spreadsheetView); 
    Scene scene = new Scene(hBox); 
    primaryStage.setScene(scene); 
    primaryStage.show(); 
    } 
}

它使用上点击鼠标时，检查表视图并点击它的鼠标处理火灾FX新的对话然后接受输入并更新fx表视图。

table.setOnMousePressed(new   EventHandler<MouseEvent>() { 
    @Override 
    public void handle(MouseEvent event) { 
     if (event.getClickCount() == 1) { 
      Call dialogue method of java fx   
     } 
    } 
}); 

或者如果你想请右键单击您可以创建细胞

如

FirstNameCol.setCellFactory(new Callback<TableColumn<Person, String>, TableCell<Person, String>>() { 
    @Override 
    public TableCell<Person, String> call(TableColumn<Person, String> col) { 
     final TableCell<Person, String> cell = new TableCell<>(); 
     cell.textProperty().bind(cell.itemProperty()); // in general might need to subclass TableCell and override updateItem(...) here 
     cell.setOnMouseClicked(new EventHandler<MouseEvent>() { 
      @Override 
      public void handle(MouseEvent event) { 
       if (event.getButton == MouseButton.SECONDARY) { 
        // handle right click on cell... 
        // access cell data with cell.getItem(); 
        // access row data with (Person)cell.getTableRow().getItem(); 
       } 
      } 
     }); 
     return cell ; 
    } 
});
