i am supposed to deal with IO_Textedit and i am struggling now.
in order to edit the text, at first i should inherit io_field and io_Frame into IO_Textedit.
i am working on the dynamic date and non-dynamic data constructors respectively.

The difference between dynamic and non-dynamic data constructor is dynamic constructor sent the class to creat series of string and non-dynamic dayta should get the pointer string as a parameter. in public function, especially i have focused on void *data();

while reviewing the last first assignment, i have follewed it including io_edit function step by step.
