i do not understand as i give you Source CODE of "native" Control which are well document at MSDN
the API for those 27 Windows Control exist since beginning and have never change
i have "try" to use same Name for Method and VAR to make it "compatible" to Xbase++ Control
so you need only to include DXE.CH and it should work like same Xbase++ Control ( but might have some Extra )
the "Problem" was to use Express++ DC Syntax as i never have used Express++ (shame on me)
---
even if i do not use Xbase++ any more (now harbour / HMG / Fivewin) i would always support my Work of DXE LIB
a "Problem" might be if i got a Ot4Xb "Problem" to contact Pablo to ask him.
this is why i ask if somebody, using Xbase++ v2.x, will try to convert Qt4Xb into EXTERNAL of Xbase++ v2.x
