Columns, headers and pages cannot (visualy) be subclassed.
Why is this and how should one deal with this?

Example: when a user clicks a page in a pageframe i want its caption to turn bold so the user can see he/she has seen the page.
I now have 'This.FontBold=.T.' in the Click() of all the applications pages (about 70 pages total). Now the user decided he/she doesn't want the page's caption to turn bold but red. Now i have to change the code at 70 places! This cannot be the goal of OOP.

For properties i can use SetAll() but there's no such function for methods.

I wonder how you guys deal with this, please let me know.


Thanks,

Marco.

BTW: Optionbuttons can be subclassed, so can optiongroups. Subclassed optionbuttons cannot be used in a subclassed optiongroup!?!?!?!?
