Widget features

Features, as used by these widgets, affect the way the widget looks and/or feels. Most features have a visible effect. Multiple features may be manipulated by or'ing values together. For instance: (FLVF_ROW_HEADER | FLVF_ROW_DIVIDER). Features are manipulated by one of four functions:

• feature - which will set the features to a specific group.
• feadure_add - which will add new features without affecting exisiting ones.
• feature_remove - which will remove a set of features without affecting other features.
• feature_test - which will determine if a enitre set of features are defined.

feature(FLVF_MULTI_SELECT | FLVF_ROW_HEADER )
Will set the multi select and row header features while turning off all other features.

feature_add(FLVF_MULTI_SELECT | FLVF_ROW_HEADER )
Will add multi select and row header features to the existing features.

feature_remove(FLVF_MULTI_SELECT | FLVF_ROW_HEADER )
Will remove multi select and row header features while leaving any other set features as is.

feature_test(FLVF_MULTI_SELECT | FLVF_ROW_HEADER )
Will test if both multi select and row header features are on. It will return true only if both are on.

FLVF_NONE

This affects no features at all. Tests will always be true, adding or removing will change nothing, and setting this feature will turn off all features.
