And to add < bg > dodefault() is not needed for built-in events' baseclass code unless you used NODEFAULT. ie:

*Lostfocus is built-in.
this.Setfocus

This wouldn't work to keep focus on object as default lostfocus code (implicit dodefault) running after your code causes it to lose focus. Adding a NODEFAULT would do. Remember if you subclassed this object and adding code to lostfocus you're overriding only your parent class code not baseclass code.

Dodefault(parmsIfAny) can be called at any place (after,before or inline your overriding code) and as many times as you want in your code. It's as if you copy&pasted default class code there (rarely you might want to do it).

Assume you've init code in your grid class which provides entire row coloring. You put one grid from that class on to your form and decide you want to add dynamicfontbold in its init.

* Init
this.SetAll('DynamicFontBold',"(myAlias.myAmount > 1000)")

That'd provide dynamicfontbold but grid would lose its coloring defined in class. Then to provide it too you'd copy&paste the parent class code :

* Init
* Parentclass code
this.SetAll('DynamicFontBold',"(myAlias.myAmount > 1000)")

Dodefault() does that copy&paste :)

* Init
dodefault()
this.SetAll('DynamicFontBold',"(myAlias.myAmount > 1000)")
