Hello,

I have to implement not java like regex handling in the column filter.
Regex should handle cases like "Di*ry" or "*ry" or "d*t*n*" all of them should resolve word "Dictionary", but not "dictionar" or "dicnioary" .

Is it possible to extend existing TextMatchingMode with the new one or maybe there is another way to do it?

Thanks,

What you actually need is to convert the input String that contains a * to a Java regular expression. We provide the FilterRowRegularExpressionConverter that actually does exactly the same.

We show the usage in the _6031_GlazedListsFilterExample:

configRegistry.registerConfigAttribute(
        FilterRowConfigAttributes.TEXT_MATCHING_MODE,
        TextMatchingMode.REGULAR_EXPRESSION,
        DisplayMode.NORMAL,
        FilterRowDataLayer.FILTER_ROW_COLUMN_LABEL_PREFIX
                + DataModelConstants.FIRSTNAME_COLUMN_POSITION);

configRegistry.registerConfigAttribute(
        CellConfigAttributes.DISPLAY_CONVERTER,
        new FilterRowRegularExpressionConverter(),
        DisplayMode.NORMAL,
        FilterRowDataLayer.FILTER_ROW_COLUMN_LABEL_PREFIX
                + DataModelConstants.FIRSTNAME_COLUMN_POSITION);

Thanks, Dirk
It is exactly what I was looking for.
