[bindable[, attribute-list]] returntype
function-name(params)
}
attribute-list
Specifies
zero or more attributes that apply to the function prototype for a property or
a method in an interface or dispinterface. The following
attributes are accepted: helpstring, helpcontext, string, defaultbind,
displaybind, immediatebind, propget, propput, propputref,
and vararg. If vararg is specified, the last parameter must be a
safe array of VARIANT type. Separate multiple attributes with commas.
Example
[uuid(. . .)]dispinterface MyObject
{
properties:
methods:
[id(1),
propget, bindable, defaultbind, displaybind]
long
x();
[id(1),
propput, bindable, defaultbind, displaybind]
void
x(long rhs);
}
Remarks
The bindable
attribute indicates that the property supports data binding. This allows
the client to be notified whenever a property has changed value. (If you want
the client to be notified of impending changes to a property, use the requestedit attribute.)
Because the bindable
attribute refers to the property as a whole, it must be specified wherever
the property is defined. Therefore, you need to specify the attribute on both
the property-accessing function and the property-setting function.
Flags
