如何利用Ubuntu Clipboard来复制并粘贴内容

Answer 1

在Ubuntu平台里，有一个Clipboard API的接口。在这篇文章中，我们将介绍如何使用该API接口来复制和粘贴内容。
具体的API介绍，可以在网址：
https://developer.ubuntu.com/api/apps/qml/sdk-15.04/Ubuntu.Components.Clipboard/
为了测试Clipboard的功能，我们使用了如下的代码：

import QtQuick 2.0
import Ubuntu.Components 1.2

/*!
\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: "clipboard.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("clipboard")

Column {
clip: true
anchors.centerIn: parent
spacing: units.gu(1)

Image {
id: image
width: 50
height: 50
source: "images/pic1.jpg"
}

TextArea {
id: editor
text: "This is cool!"
}
MimeData {
id: mimeData
color: "green"
text: editor.text
urls: [image.source]
}
Button {
text: "Copy method one"
onClicked: Clipboard.push(mimeData)
}
Button {
text: "Copy method two"
onClicked: {
//Clipboard.push(editor.text);
//Clipboard.push(["application/x-color", "green"]);
Clipboard.push(["application/x-color", "red",
"text/plain", editor.text,
"text/plain", [image.source]
]);
}
}
Button {
text: "Copy method three"
onClicked: {
var mimeData = Clipboard.newData();
mimeData.text = editor.text;
mimeData.color = "green";
mimeData.urls.push(image.source);
Clipboard.push(mimeData);
}
}

Row {
spacing: units.gu(1)
Button {
text: "Paste"
onClicked: {
editor1.text = Clipboard.data.text;
editor1.color = Clipboard.data.color;
image1.source = Clipboard.data.urls[0];

}
}
Button {
text: "Clear the textarea below"
onClicked: {
//Clipboard.clear();
editor1.text = "";
image1.source = "";
}
}
}
TextArea {
id: editor1
}

Image {
id: image1
width: 50
height: 50
}
}
}
}
