Qt for Maemo: Animation Example 
-------------------------------

This Qt example application demonstrates how easily you can use the Qt 
Animation Framework to create animations and transitions for Qt applications.

The example has been tested to work on the Nokia N900 (Qt for Maemo TP2), 
Nokia N97, and Nokia X6 (Qt for Symbian 4.6).

--------------------------------------------------------------------------------

PREREQUISITES 

Qt basics 

--------------------------------------------------------------------------------

REQUIRED CAPABILITIES 

None

--------------------------------------------------------------------------------

KNOWN ISSUES 

- Previous [<<] and Next [>>] buttons on the Image view are not implemented.
- Images are currently bundled within the application binary. The 
  implementation can easily be improved by adding the possibility of browsing 
  the device file system and selecting the folder where images are retrieved.
- For animations with greater performance demands, use QGraphicsView
  [see the Qt documentation for more details].
- Image size in Image view is hard coded – no scaling functionality implemented.
   
-------------------------------------------------------------------------------- 

RUNNING THE EXAMPLE 

There are two views in the application:   

- File view - Presents the list of available images
- Image view - Presents the image selected from the File view

Select the image by tapping it once. You can return to the File view from the 
Image view by pressing the 'Back' button on the toolbar.

The toolbar can be shown/hidden by tapping anywhere on the Image view screen.

BUILD & INSTALLATION INSTRUCTIONS FOR MAEMO 5 FREMANTLE 

You need Maemo 5 SDK, Scratchbox, and Qt for Maemo installed to build the 
example source.

Maemo 5 SDK can be found from: 
http://www.forum.nokia.com/info/sw.nokia.com/id/c05693a1-265c-4c7f-a389-fc227db4c465/Maemo_5_SDK.html

Installation instructions can be found from:
http://wiki.maemo.org/Documentation/Maemo5_Final_Installation


Building the source
""""""""""""""""""" 
1. Launch Scratchbox. 
 
2. Extract the files from the QImageViewer ZIP archive. 
 
3. Go to the folder where QImageViewer.pro is located.

	qmake
	make

Select the target (ARMEL/X86) with 'sb-menu' before executing 'qmake/make' 
depending on whether you are building for emulator (Xephyr) or device.

Running in Scratchbox with Xephyr (running example in emulator) 
""""""""""""""""""""""""""""""""" 
1. Launch Xephyr and Scratchbox: 

    Xephyr :2 -host-cursor -screen 800x480x16 -dpi 96 -ac &

2. Under Scratchbox, run the following commands to use Xephyr and  
   initialise the Hildon environment: 
 
    export DISPLAY=":2" 
    af-sb-init.sh start

3. Install the .deb package: 

    dpkg -i QImageViewer.deb 

4. Start the application from the QtImageViewer icon in the 'More' folder in 
   the emulator.
