JavaFX 菜单项在右侧显示快捷方式

Question

Take for example the menu items from the edit menu in JavaFX Scene Builder

See how they display the shortcuts on the right? Is there any easy way to achieve the same effect using JavaFX? Thanks.

Answer 1

You can add an accelerator key in scene builder or add it directly in the fxml file like so

      <MenuItem mnemonicParsing="true" onAction="#mnuSaveAction" text="%menu.title.save" fx:id="mnuSave">
        <accelerator>
          <KeyCodeCombination alt="UP" code="S" control="DOWN" meta="UP" shift="UP" shortcut="UP" />
        </accelerator>
      </MenuItem>

If by "in javafx" you mean without using fxml you can use mnuSave.setAccelerator(KeyCombination);

Answer 2

If your are not using fxml file then you can add key combination like below.

MenuItem gotoLine = new MenuItem("Goto");
KeyCombination gotoKeyCombination = new KeyCodeCombination(KeyCode.G, KeyCombination.CONTROL_DOWN);
gotoLine.setAccelerator(gotoKeyCombination);
gotoLine.setOnAction(event -> {
            System.out.println("CTRL+G event triggered");
            System.out.println(event.toString());
 });
