GlazedLists FIlter Strategy for Custom Object [message #1422270] Fri, 12 September 2014 15:32 Go to next message

Hi,

I have a Cell that has a DataValue that is a Custom Object.
I would like to use Text Filtering, but by default it searches the Object.toString() which is not what I want, instead i will provide a custom converter that does Object.getSearchableString() or the like.

I figured that i could use a DefaultGlazedListFilterStrategy and Override getTextFilterator, and maybe that would work, but I would prefer to be able to provide a DisplayConverter via ConfigAttribute for this purpose.

What is the recommended approach?

Appreciated,

Jay

You need to register a IDisplayConverter for the ConfigAttribute FilterRowConfigAttributes.FILTER_DISPLAY_CONVERTER

The corresponding example can be found in the examples app: Tutorial Examples -> GlazedLists -> Filter -> GlazedListsFilterCustomTypesExample

I did do that, but received a ClassCastException (String) when it tried to use the same filter for the header/filter row, in which i typed the search text.

I suppose as a workaround i could just catch the exception and pass the string.

Did you ensure to also register the converter for the column itself? Without seeing what you did I don't know about your issue in detail and what you did wrong. The example works with custom types, so I assume you missed something and you don't need to catch anything.

One further question: Are you using a combo box for filtering or a text field? Because if you are using a text field, are you sure the converter is able to resolve the custom type by a incomplete String?

It's a text field, which is i think where my problem is. I'm not sure how to convert an incomplete string to a type ... but i do have an idea on how to solve the problem now. Thank you.
