/*! \class edelib::Icon
|
|
|
|
This class gives support for KDE-compatible icon themes.
|
|
Icons are identified with their standard names, and the class
|
|
will fetch corresponding image from its standard location.
|
|
User can easily change all icons at once by setting the icon
|
|
theme.
|
|
|
|
There should be a freedesktop.org standard for icon names,
|
|
but I'm not aware of one so we will implement a sort of KDE
|
|
compatibility. Please refer to Icon theme documentation for
|
|
details.
