Webdialog component and group html attributes

4dHans · 27 Sept 2010, 23:52

I am trying to make a webdialog that updates with the selection, just like component options does, and sets the content of the attribute: ("dialog_product","html_code","#{value}").
So basicly, the dialog will be like a webpage for the component, the html is the value

Dictionary;dialog_product
Name;html_code
Value;<html><body><a href=""><i>BUY HERE!!! 0.5mm x 0.37mm</i></a></body></html>

,the dialog, that updates with the selection, will do that value. Could someone help me?

Normally, you would wish to use an Observer to "make changes happen" in your webdialog.. however the SelectionObserver is still bugged.

You may try using the onSelectionBulkChange callback of a SelectionObserver custom subclasss, to trigger your changes. Then use the query methods of the Selection collection class (http://code.google.com/apis/sketchup/docs/ourdoc/selection.html ) to determine if the selection is a single object (method single_object?), and if so test if it is an instance of Sketchup::ComponentInstance, and if it is.. whether it has an attribute dictionary of a certain name, and if so, make your changes.

Note that single_object? will return true if you have a surface selected- which is multiple faces. To check if the selection really contains only one entity use the length property.
