Form XML code:
<element_name.image>
<Image imageUrl="qx://application/lycia" imageScaling="Both"/>
</element_name.image>
By default, widgets have no images and, thus, this property is absent from the form XML code. The property value will appear in the form XML code only once any image is added to the form.
Theme property filter XML code:
<DoStyleAction>
<SetProperty>
<PropertyPath>
<PropertyName>Image</PropertyName>
<PropertyName>ImageScaling</PropertyName>
</PropertyPath>
</SetProperty>
</DoStyleAction>
Possible values:
Default value: not specified (in Lycia Form Designer), none (in Lycia Theme Designer)
