In the specification config.xml of a wirecloud widget, we can set initial width and height
<Platform.Rendering width="x" height="y"/>
When I put in something like width 300 and height = 80, the widget gets much bigger and overflows the screen. In the specification I only see that the width field defines the width.
I see in example widgets values like 5 and 8. So what unit is the width and height?
WireCloud prior to 0.8.0 only supports columns and row as units. Pixels and percentages are supported from WireCloud 0.8.0 onwards.
See the documentation for more info.
