Hi,
ObjectBinaryToText method can save object structure to string, but how
save only some propertys? I could use RTTI and TypeInfo, but
ObjectBinaryToText can parse property hierarchy
(Propery1.Subproperty1.Color etc). Or how I can save and read object
from string without object name?
Example: I am creating simple theme manager which save settings of
some control (e.g. TEdit) and must read it not paying attention to the
component name (Edit1, Edit2, Edit3 etc...) Must work like a template.
tskinmanager of MSEgui does something similar, see lib/common/kernel/mseskin.pas.
Every MSEgui component has the procedure updateskin() which normally will be called after loading the form. tmsecomponent.updateskin() calls the global oninitskinobject handler which is assigned to the active <tskincontroller> which updates the default values of the component according to the skin settings. Values which are already set by the form resources normally are not changed so it is possible to define component specific exceptions to the current theme, for instance a specific color, frame or font.
objectbinarytotext() converts from binary streamed data written by twriter to a human readable text representation, it does not scan the properties, twriter.writeproperties() does this. The whole Delphi/FPC component streaming system is very locked because of the many private fields and procedures. I think it is difficult to use it as base for your undertaking.
