* Properties can be accessed and set from a TextChain with:
|
|
* - T TextChain::GetPROPNAME(SdrTextObj *)
|
|
* - void TextChain::SetPROPNAME(SdrTextObj *, T)
|
|
* where T and PROPNAME are respectively type and name of a property.
|
|
*
|
|
* To add a property PROPNAME of type T (and its interface) in TextChain:
|
|
* 1) Add
|
|
* "DECL_CHAIN_PROP(PROPNAME, T)"
|
|
* in class ImpChainLinkProperties;
|
|
* 2) Add
|
|
* "INIT_CHAIN_PROP(PROPNAME, V)"
|
|
* in constructor of ImpChainLinkProperties below
|
|
* (V is the initialization value for PROPNAME)
|
|
*
|
|
* 3) Add
|
|
* "DECL_CHAIN_PROP_INTERFACE(PROPNAME, T)"
|
|
* in class TextChain (under "public:");
|
|
* 4) Add
|
|
* "IMPL_CHAIN_PROP_INTERFACE(PROPNAME, T)"
|
|
