/**
|
|
The WOAssociation class is a class for objects which represents values of GNUstepWeb attributes specified in declaration files (.gswd).
|
|
|
|
WOAssociation object get or set value according to values key. For exemple:
|
|
|
|
MyString1: GSWString
|
|
{
|
|
value = "aLabel";
|
|
};
|
|
|
|
MyString2: GSWString
|
|
{
|
|
value = label;
|
|
};
|
|
|
|
MyString3: GSWString
|
|
{
|
|
value = myMember.label;
|
|
};
|
|
|
|
|
|
At runtime, the GNUstepWeb parser scans an HTML template (.html) and it's declarations (.gswd) and creates 3 dynamic element objects of type GSWString.
|
|
In the case value= "label", the string value will be a constant string "aLabel".
|
|
In the case value = label, the value came from method "label" or member "label" of the component (by valueForKey: mechanism).
|
|
In the case value = myMember.label, value came from method "label" or member "label" of the object returned by calling valueForKey:@"myMember" on the component.
|
|
|
|
NEW FEATURE: negate. add a "!" in front of your key path and the result will be negated.
