Text Binding Custom Menu

Read the original article：Text Binding Custom Menu

Problem Description

How to achieve the following effect by binding a custom menu to the Text component:

• The menu displayed by bindSelectionMenu automatically disappears when the user touches the screen.
• Long press to bring up the custom menu; double-tap gesture does not display the default menu.

Background Knowledge

• The gesture binding method is used to bind different types of gesture events to a component and set the response methods for these events.
• The bindSelectionMenu method can set a custom selection menu for Text. For usage details, please refer to the documentation on binding custom menus to text.

Solution

• Add a click event to the outermost component of the page to close the menu, achieving the effect of the menu disappearing when the screen is touched.
• The double-tap gesture to bring up the default menu is the system default specification. You can bind a double-tap event to the Text component to override the default behavior.

@Entry
@Component
struct BindMenuPage {
  controller: TextController = new TextController();

  build() {
    Column() {
      Text(undefined, { controller: this.controller }) {
        Span('Hello World');
        ImageSpan($r('app.media.startIcon')) // Image resources need to be replaced by yourself.
          .width('100px').height('100px');
      }
      .parallelGesture(
        // Rewrite the double-tap gesture event to close the menu.
        TapGesture({ count: 2 })
          .onAction(() => {
            this.controller.closeSelectionMenu();
          }), GestureMask.Normal)
      .copyOption(CopyOptions.InApp)
      // Set TextResponseType.LONG_PRESS to display a custom menu by long-pressing.
      .bindSelectionMenu(TextSpanType.DEFAULT, this.LongPressImageCustomMenu, TextResponseType.LONG_PRESS);
    }.width('100%').height('100%')
    .justifyContent(FlexAlign.Center)
    .onClick(() => {
      // Set a click event on the root node of the page to close the menu.
      this.controller.closeSelectionMenu(); // Close Menu
    });
  }

  @Builder
  LongPressImageCustomMenu() {
    Scroll() {
      Menu() {
        MenuItemGroup() {
          // Image resources need to be replaced by yourself.
          MenuItem({ startIcon: $r('app.media.startIcon'), content: 'Long Press Image Menu 1', labelInfo: '' });
          MenuItem({ startIcon: $r('app.media.startIcon'), content: 'Long Press Image Menu 2', labelInfo: '' });
          MenuItem({ startIcon: $r('app.media.startIcon'), content: 'Long Press Image Menu 3', labelInfo: '' });
        };
      }
      .backgroundColor('#F0F0F0');
    };
  }
}

Verification Result

If change the content as "Menu 1":
