\QC creates the project and displays its contents under the \gui Projects
view on the sidebar. You can only see a .pro file under the project as we
created an empty project, but the remaining bits will be added
during the course of this tutorial.
\QC generates a default QML file that you can modify to create the main view
of the application.
\section1 Creating the Main View
The main view of the application displays an SVG bubble image at the center
of the main window.
\list 1
\li In the \gui Edit mode, right-click on the \b{accelbubble} project
and select \gui{Add new} to open the \gui{New File} dialog.
\li Select \gui{Qt > QML File (Qt Quick 2)} and click \gui Choose to
give a name to the QML file.
\li In the \gui Name field, type "accelbubble" and select \gui Next.
\li Select \gui Finish to add accelbubble.qml to the project.
\endlist
\QC adds a default QML file containing a Rectangle. Here is how the QML
file looks:
\snippet qml/tutorial_initialqml.qml initialcode
Now let us edit accelbubble.qml to add the bits required for our
application.
To use the Bluebubble.svg used by the Qt Sensors example, Accel Bubble, in
your project, you must copy it to the project directory (same subdirectory
as the QML file) from the examples directory in the Qt installation
directory. For example:
\c {C:\Qt\Qt5.2.0\5.2.0\msvc2010\examples\sensors\accelbubble\content}.
The image appears in the \gui Resources pane. You can also use any other
image or a QML type, instead.
\list 1
\li Replace the existing import statement with the following:
\li In the \gui Projects view, double-click the main.qml file
to open it in the code editor.
\snippet qml/tutorial_updatedmainview.qml imports
\li Modify the properties of the ApplicationWindow type to specify the
application name, give the ApplicationWindow an id, and to set it
visible, as illustrated by the following code snippet:
\li Replace the Rectangle type with ApplicationWindow, which
will be the top-level window for our application.
\li Set the \a id, \a title, \a visible, and the window dimension
properties (width and height) with the values given in the
following snippet:
\quotefromfile qml/tutorial_updatedmainview.qml
\quotefromfile accelbubble/main.qml
\skipto ApplicationWindow
\printuntil true
\printuntil visible
\skipto /^\}/
\printuntil }
\li Click \gui Design to open the file in \QMLD.
\li In the \gui Navigator pane, select \gui Button and press \key Delete
to delete it.
\li In the \gui Library view, \gui Resources tab, select Bluebubble.svg
and drag and drop it to the canvas.
\li In the \gui Properties pane, \gui Id field, enter \e bubble to be
able to reference the image from other places.
\li In the code editor, add the following new properties to the image to
position the image at the center of ApplicationWindow when the
application starts:
\quotefromfile accelbubble/main.qml
\skipto Image
\printuntil bubble.width
\li Set the x and y position of the image based on the new
properties:
\dots
\printuntil centerY
\skipto /^\}/
\printuntil }
\endlist
\section1 Adding an SVG Image
Here is how the accelbubble.qml file looks after you made the changes:
SVG is an XML-based image format that enables you to combine vector
graphics, raster graphics, and text into one image. It is based on
an open standard developed and maintained by \l{http://www.w3.org/}{W3C}.
Qt supports the \l{http://www.w3.org/TR/SVGTiny12/}{SVGT} v1.2, which is a
trimmed version of the \l{http://www.w3.org/TR/SVG12/}{SVG Full v1.2}
specification, for mobile devices.
You can copy the Bluebubble.svg used by the Qt Sensors example, Accel
Bubble, to your project directory or find an SVG image that uses SVGT v1.2.
\note If you choose to create a new SVG image, ensure that the \a svg root
element has the \a version attribute with the value 1.1 or 1.2, and baseProfile
with \c tiny.
\list 1
\li Open accelbubble.qml in \gui Edit mode and add an Image type
within the ApplicationWindow.
\li Set the image \a id, \a source, and \a smooth properties as shown
in the following code block:
\quotefromfile qml/tutorial_updatedmainview.qml
\skipto Image
\printuntil true
\li Add the following new properties to the image:
\dots
\printuntil bubbleCenter:
\note These properties are used to position the image
at the center of ApplicationWindow when the application starts.
\li Set the x and y position of the image based on the new
properties.

\li Name the file as \a main.cpp and click \gui Next.
\li Select \gui Finish to add main.cpp to the project and open it in

\section1 Running the Application
The application is complete and ready to be deployed to an Android device:
\list 1
\li Enable \e{USB Debugging} on the device.
\li Connect the device to the development PC.
If you are using a device running Android v4.2.2, it should prompt you to
verify the connection to allow USB debugging from the PC it is connected
to. To avoid such prompts every time you connect the device, check
"Always allow from the computer" and select \gui OK.
To run the application on the device, press CTRL + R keys in \QC
\gui Edit mode.
\li To run the application on the device, press \key {Ctrl+R}.
