About TCalendar
Posted: Mon Dec 07, 2020 10:07 amHello, In our program we ask for a range di date, using 2 DatePicker, I would like change it using the Month Calendar Control
that is supported by FiveWin by the TCalendar class.
What I saw, trying the testcal sample is the some animations are missing, I fixed it adding these pieces of code on the sample (and on every use)
and
another way is overriding HandleEvent in TCalendar, of course.
Here a couple of video with the missing animations :https://imgur.com/a/vA0lNfn
Another piece that is missing is the query for size of the control, that I would implement in this way:
From MSDN:
MonthCal_GetMinReqRect
Retrieves the minimum size required to display a full month in a month calendar control. Size information is presented in the form of a RECT structure.
MonthCal_SizeRectToMin
Calculates how many calendars will fit in the given rectangle, and then returns the minimum size that a rectangle needs to be to fit that number of calendars.
that is supported by FiveWin by the TCalendar class.

- Code: Select all Expand view
- // my fix
__objDelMethod(oCal, "HandleEvent" )
__objAddMethod(oCal, "HandleEvent", @simplyNil())
__objDelMethod(oCal2, "HandleEvent" )
__objAddMethod(oCal2, "HandleEvent", @simplyNil())
// *** ***
and
- Code: Select all Expand view
- static function simplyNil()
return nil
