Initiate a request to get the render information for a given
component.
The information can be for example the exact pixel size and position,
the font size, visibility, margin, padding or border of the component in
the browser. See possible values from the {@link CssProperty}
enumerable.
The information will be delivered asynchronously from the client, and
passed as a parameter to the callback method.
You can limit the amount of properties transmitted over the connection
by passing the desired property names as the last parameter for the
method.
- Parameters:
c - The component whose render information you wish to get.
cb - The callback object which will receive the information when it is
available.
props - Optional. The list of CSS properties you wish to get from the
client (limit the amount of transferred data). You can pass any
type of objects here, the __str__() method will be
used to convert them to actual property names. Preferably use the
CssProperty enumerable for feasible values.
