quick-widgets is an application to facilitate creating and deploying home screen widgets.
see thread on talk
Contents |
Features
- run Qt Quick applications as home widgets
- suspend widget when not on current home screen
- access to system calls in QML (wrapping QProcess)
- fix widget to size or let content determine the size
- restore after reboot/crash
Wish list
- base widgets
- more event bindings directly in qml
Basic Example
Web Browser widget
import Qt 4.7 import QtWebKit 1.0 Item { // Modify these to customize // widget width width: 300 // widget height height: 350 // the url to display property string url: "http://touch.facebook.com" // the optimum width for the website. The page is scaled down // from this width to the widget's width property int optimal_width: 340 // interval when to reload the page // setting it to 0 means never refresh property real reload_in_minutes: 10 // end user mods. id: main MouseArea { anchors.right: parent.right width: 30 height: parent.height onClicked: { } } Rectangle { anchors.fill: parent radius: 10 color: "gray" opacity: 0.6 } Text { id: txt anchors.centerIn: parent text: "loading..." color: "white" } WebView { id: browser transformOrigin: Item.TopLeft property bool scaled: false smooth: true visible: false preferredWidth: optimal_width preferredHeight: parent.height url: parent.url Behavior on y { PropertyAnimation {} } onUrlChanged: { y = 0 } onLoadFinished: { if (!scaled) { browser.contentsScale = main.width/browser.width scaled = true; } browser.visible = true //console.log('loaded') txt.z = 0 } } MouseArea { anchors.right: parent.right width: 30 height: parent.height onClicked: { var inc = main.height*0.9 if (mouse.y > main.height/2) { var dy = Math.min(inc, browser.contentsSize.height-main.height+browser.y) browser.y -= dy } else { var dy = Math.min(inc, Math.abs(browser.y)) browser.y += dy } } } Timer { id: refresh interval: 1000*60*parent.reload_in_minutes running: runtime.isActiveWindow repeat: true onTriggered: { txt.z = 1 browser.reload.trigger() } } }
