Native Window ID Example

Demonstrates obtaining the native OHOS window ID of a Qt window.


The main window has a button that creates additional windows. For every window the example calls QtOhosExtras::tryGetNativeWindowId() after the window has been shown and displays the result in the window title, or <invalid> when the returned pointer is null.

Note: tryGetNativeWindowId() must only be called after the window has been shown, and the returned ID is not guaranteed to remain valid for the lifetime of the application.
