\title Application Icon Example
The example shows how to add an application icon to a mobile application.
\image appicon_screenshot.png The icon on a Nokia XPressMusic 5800
\section1 Creating an icon for Maemo
Maemo expects the icon of an application to be a 64x64 PNG image file. The
file name of the icon should be the same as the executable with a \c .png
extension. You also need a \c .desktop file that gives the window manager
hints about the application, such as name, type and icon.
\quotefile examples/widgets/applicationicon/applicationicon.desktop
The \c Icon field should also contain the name of the executable. On the
device, application icons are stored in the
\c /usr/share/icons/hicolor/64x64/apps directory
and desktop files in the \c /usr/share/applications/hildon directory.
\section1 Creating an icon for Symbian
Symbian uses Scalable Vector Graphics (SVG Tiny 1.1+) to render
application icons in the application menu. Therefore icons could be
created manually with a text editor, since SVG files are plain text with
XML syntax, but usually you would use a vector graphics program that is
able to output SVG files. Popular graphics programs such as Adobe
Illustrator or Inkscape are able to do so.
For best results, the icon should be created on a 44x44 pixel canvas.
Otherwise the image might be scaled in unexpected ways.
Once you have created your icon, make sure that it is stored according to
the SVG-Tiny 1.1+ standard. Inkscape, for instance, is not able to save
images that way, but there are tools that can convert general SVG files
into the Tiny format. For instance, the svg2svgt tool that is bundled with
Symbian 3rd and 5th editon SDKs under the folder s60tools can do this
conversion to some extent. Another tool to convert SVG to SVG Tiny is SVG
Pony.
\section1 Adding the icons to the project
Edit the .pro file and specify the ICON variable for the symbian target.
For Maemo, we need to add that the \c .desktop and icon file should be
installed.
\quotefile examples/widgets/applicationicon/applicationicon.pro
Currently, Qt Creator doesn't include the icon and desktop files in the
application package for Maemo, merely the executable file is included. As a
workaround for this, the files can be added manually in the Projects tab.
In the "Create Package" build step for the Maemo target, the \c .desktop
file and icon can be added to be a part of the package contents.
Unfortunately, these additions are only stored as a part of the
\c .pro.user file. This issue will be resolved in a future release of
Qt Creator.
