How to determine whether the keyboard is enabled on an Ubuntu mobile phone?

In some applications, we need to determine whether the keyboard has appeared. If it appears, we sometimes don't want a keyboard. We can also remove the keyboard through software. In this article, we will introduce how to implement this.

import QtQuick 2.0import Ubuntu.Components 1.1/*!    \brief MainView with a Label and Button elements.*/MainView {    // objectName for functional testing purposes (autopilot-qt5)    objectName: "mainView"    // Note! applicationName needs to match the "name" field of the click manifest    applicationName: "inputmethod.liu-xiao-guo"    /*     This property enables the application to change orientation     when the device is rotated. The default is false.    */    //automaticOrientation: true    // Removes the old toolbar and enables new features of the new header.    useDeprecatedToolbar: false    width: units.gu(60)    height: units.gu(85)    Page {        title: i18n.tr("inputmethod")        Column {            spacing: units.gu(2)            TextField {                id: input            }            Text {                text: "Input method: " + "<b>" + Qt.inputMethod.visible + "</b>"            }            Button {                text: "Hide Input method"                onClicked: {                    Qt.inputMethod.hide();                }            }        }        Component.onCompleted: {            var keys = Object.keys(Qt.inputMethod);            for(var i = 0; i < keys.length; i++) {                var key = keys[i];                // prints all properties, signals, functions from object                console.log(key + ' : ' + Qt.inputMethod[key]);                if (key === "locale") {                    console.log("Native lang: " + Qt.inputMethod[key].nativeLanguageName);                }            }            var rect = Qt.inputMethod.keyboardRectangle;            console.log("keyboard size: " + rect.width + " " + rect.height);        }    }}

In the above example, we can see that when the keyboard is not started:

Qt. inputMethod. visible

Is false. When the keyboard is started, its value changes to true. Of course, we can also use the following methods:

 Qt.inputMethod.hide();

To make the keyboard disappear.
