How can I dynamically register the menu?

[baoqing1124]

I need to register the menu dynamically during the use of the application, but I have tested that the menu cannot be displayed when I register the menu asynchronously. What should I do to achieve this function? Can anyone help me?

Hey @baoqing1124,

Can you provide a reproducible example? We're performing dynamic registration of menu actions (see here for an example) all the time in the framework. It's supposed to work.

hi~ @msujew
This is an example based on theia master, I modified the the code in "examples\api-samples\src\browser\menu\sample-menu-contribution.ts" at line 277.

Looking into the code, it actually looks like the menu is filled/created once when it is made visible. Every other modification to the menu is ignored afterwards (unless you recreate it by changing the window.menuBarVisibility setting). I've created #13719 to track this.

@baoqing1124, for now, you can see how the Arduino IDE solves this: https://github.com/arduino/arduino-ide/blob/aa9b10d68e6653b7f40ab920173c7964aaefbfa4/arduino-ide-extension/src/common/main-menu-manager.ts#L7

If you want to unregister submenus, there is a non-API way to do it: https://github.com/arduino/arduino-ide/blob/aa9b10d68e6653b7f40ab920173c7964aaefbfa4/arduino-ide-extension/src/browser/menu/arduino-menus.ts#L198
