[ANNOUNCE] Quick Widgets 0.3.2 - quickly deploy qt quick as widgets

2 Attachment(s)

Hi all,

I had a stab at my first application - called quick-widgets. It allows to run Qt Quick applications (qml files) as desktop (hildon-home) widgets. The code is heavily based on venemo's q-extras and sticky notes. So A BIG THANKS for doing all the hard work.

There are plenty of qml examples out there you can use., e.g. http://doc.qt.nokia.com/qt-maemo-4.7...eexamples.html

Features

as said - run qml applications as widgets
similar to qmlviewer, provide

Code:

runtime.isActiveWindow

to suspend the widget.
use the size of the qml application or specify custom size which will scale the qml if programmed to allow it
as sticky-notes, restore all widgets on reboot
access to QProcess qml wrapper, see example in /opt/quick-widgets/examples
dynamically resize widget to content size
support from qt mobility v0.2.3
add widgets from command-line v0.2.5
make widget auto-rotate with the phone orientation (customisable) v0.3.0

Usage

enable extras-devel and install
start the application to each time you want to add a new widgets
select a qml file
optionally give it a fixed size which will scale the widget
optionally enable auto-rotation of the widget

To Do

listen to feedback :D

I am looking forward to people posting their useful widgets.

Examples

http://talk.maemo.org/showpost.php?p...1&postcount=25

I have attached the source for building the qml Process plugin. I am using this on my Desktop for creating widgets under Qt SDK 1.1. See README for very basic instructions.

Sorry - I know this goes back a couple of steps on your post, but how do I go from http://doc.qt.nokia.com/qt-maemo-4.7...otoviewer.html looking longingly at this qml demo of a photo viewer app to getting it on my phone as a demo?

apt-get install q-extras libhildon-extras1
install quick-widgets -

Code:

dpkg -i quick-widgets_0.1.0_armel.deb
start the application to add new widgets

To Do

write qml bindings to system calls
support custom c++ bindings
listen to feedback :D

This might be worth packaging up son one can easily create their own application wrappers as well.

Probably not a good idea as this is full screen :eek: Use the qmlviewer for this. My application is mainly targeted at widgets.

I will post an example of a widget which shows a webpage and updates it periodically soon.

Thanks! Done now. Digging through the docs and applying for upload permissions takes some time though. It isn't really the most transparent process. Hence me creating a package to make things easier from qml widgets

Re: [ANNOUNCE] Quick Widgets - quickly deploy qt quick as widgets

Here we go. a webpage view as a widget...

save it to home or MyDocs
rename to webpage.qml
load it into quick-widgets

You can edit the url field and make as many copies and instances as you want. I will also add a reload timer if wanted.

ok here is an improved version:

You can set the update/reload interval at the top of the script
You can scroll by tapping on the right hand side of the widget - top half scroll up/ bottom half scroll down.

Re: [ANNOUNCE] Quick Widgets - quickly deploy qt quick as widgets

wait wait, the problem was that i was using it with touch.facebook.com before signing in, for some reason it didn't work, but now after signning in the scrolling is working perfectly, man you app might be the solution to all the problems we had with widgets, i mean we might end up getting a facebook status update widget, or a widget that displays a contatc's last twitter/fb update (still trying to figure out this one, no website that shows the last status update of a contact :( maybe i got to find my way arround here )

Re: [ANNOUNCE] Quick Widgets 0.2.0 - quickly deploy qt quick as widgets

quick-widgets-0.2.0 has been uploaded. The new features are:

access to QProcess qml wrapper, see example in MyDocs/quick-widgets/examples
dynamically resize widget to content size

This basically means any system command output can be accessed. So this is in alternative to the Desktop Command execution widget and/or beecons.

yep that's why I didi it. With more qt mobility qml bindings it would be even better.

If anybody can think of a widget I can have a go at it. The main constraint is that it should be limited to tap actions as the home screen scrolling is taking over dragging or flicking.

The main highlights of qml are ease of use and animation eye candy.

I will have a look at passing on orientation events to qml so the widgets could be working in portrait mode.

Here is a better version of the web browser widget:

To scroll you have to tap on the right hand side of the widget. Upper half scrolls up , lower half down. Note that this prevents from clicking any links in that area (30 pixels)

It defaults to a facebook touch view.
Either cut-n-paste this code into a file named 'webwidget.qml'
or save the attached file (note it has to be renamed or saved as webwidget.qml as this site doesn't allow qml extensions).

Then load into quick widget.

Code:

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()

                          }

     }



}

Re: [ANNOUNCE] Quick Widgets 0.2.1 - quickly deploy qt quick as widgets

GreatGonzo, is there any way to auto sign in with touch.facebook.com? Every time I restart my device the widget requires me to sign in again. The scrolling sometimes messes up too, going too far up or down and leaving a blank area in the widget. I've reduced the amount the widget scrolls to fine-tune the amount of empty space, but doesn't solve the underlying problem.

Sorry I don't understand? I've changed the script to touch.facebook.com, but it requires me to sign in in the widget (which works, but is just annoying) every time I boot my device.

i imagine the script would have to point to your cookies folder somehow, thus auto sign in like with microB would be possible. but i'm just guessing. dont ask me how to make it point anywhere, cos unless the answer is draw a big ascii arrow i dont know jack. :/

EDIT: unless facebook sign in supports the web address tyoe sign in.... e.g. username:password@webaddress.com in the url field, then you would just need to edit the url in the script to have your username and password. again, just guessing, test for yourself!

You could also hook into when the website does the login and read from the DOM the username and password and save it in the offline storage, and load it back into the dom next time. ( if you need help interfacing with the dom tell me, i've already done something like this)

another option is to build the POST request properly but I am not sure how easy that is to do in the qml webview.

Be advised that both options are a bit on the gray area with regards to the facebook "no screen scrapping" policy...
