Pickdate part 2 – a control class in development

[Otto]

Hello Antonio,
thank you for helping to develop pickdate as control class.
Now I have the movemouse method ready.

Would you please help again to show me how to implement redefine and how to use
this control from a resource.

Please uncomment SET DATE TO GERMAN and use ENGLISH in func RegionDate(nMonth,cYear ).

Here is the code:

Code: Select all  Expand view  RUN

#include "FiveWin.ch"

//----------------------------------------------------------------------------//

function Main()

   local oWnd, oPickDate

   SET DATE TO GERMAN
   DEFINE WINDOW oWnd TITLE "Calendar"

   oPickDate := TPickDate():New( 10, 10,,, oWnd )

   oWnd:oClient = oPickDate

   ACTIVATE WINDOW oWnd MAXIMIZED

return nil
//----------------------------------------------------------------------------//

Hello Mr.Antonio

It is an excellent lesson to the people like me who are interested to
create classes from their existing reusable codes.

Mr.Otto

Thanks for sharing your excellent code from the beginning.

Hello,

I'm testing here but it calls a functions GradientFill() that I don't have here. I'm using FWH 8.02.

Kleyber,

GradientFill() is a new function in FWH 8.07.

You can comment out those function calls in the class.
