Display Development
When to Use
An application can obtain the default display object or all display objects by calling the Display APIs.
Available APIs
For details about the APIs, see Display.
How to Develop
Call getDefaultDisplay(): Promise<Display> to obtain the default display object. An example code snippet is as follows:
import display from '@ohos.display' // Import the module.
let disp; // disp is used to save the default display object.
display.getDefaultDisplay().then((disp) => {
console.log('display.getDefaultDisplay success, display :' + JSON.stringify(disp));
}, (err) => {
console.log('display.getDefaultDisplay failed, error : ' + JSON.stringify(err));
})
