Detailed Description

Provides scalable icons to QML.

This class is used to provide pixmaps generated from QIcons to QML. It supports generating different pixmaps for different source sizes. For that, the last component of the URL in the source property of a QML Image should correspond to the current width, like this:

Image {
    source: someIconString + '/' + width
    // ...
}

The subclasses should implement the GetIcon() pure virtual function, which should return a QIcon for a given path, where path is a QStringList obtained by breaking the URL path at '/' and leaving the width component.

Please also see the documentation for QIcon::pixmap() regarding upscaling.

Parameters

[in] path The icon path, a list obtained by breaking the URL request path at '/'.

Returns: QIcon for the path, or an empty QIcon.
