Thank you for your help. I tried your code but it didn't work.
Does someone have a get class changed for mousewheel support?
Thanks in advance

Hello Natter,
thank you for your sample.
I compiled the sample but here mouse wheel does not work.
I think a get field with mouse wheel support should work either if you click on the scrollbar or it the field has focus and you turn the wheel.
And this is not happen.
Regards,
Otto

Hi Otto:
Taking the Natter's sample try this:
Code: Select all
#include "Fivewin.ch"
Static oGet
Function Main()
Local oGet, oDlg, ;
nVal := -1
DEFINE DIALOG oDlg
TGet_Modify()
@ 1, 1 GET oGet VAR nVal ;
PICTURE "999" SPINNER
oGet:bChange:={ || MyFun( oDlg ) }
@ 1, 15 SAY "..."
ACTIVATE DIALOG oDlg CENTERED
Return Nil
//---------------------------------------------------------//
Static Function MyFun( oDlg )
oDlg:aControls[ 2 ]:SetText( oDlg:aControls[ 1 ]:cText() )
Return Nil
//---------------------------------------------------------//
Static Function TGet_Modify()
Override Method MouseWheel In Class TGet With UseTheWheel
Return Nil
//---------------------------------------------------------//
Static Function UseTheWheel( nKey, nDelta, nXPos, nYPos )
Local Self := QSelf()
If nDelta > 0
Self++
Else
Self--
EndIf
Return Nil
Best regards.

Hello Manuel,
Thank you very much for your help. This is working.
I must figure out how to implement this method into TGet class.
I use Harbour too and override I think does not exist in Harbour.
I have uploaded the snip to:

The main virtue of Override and Extend procedures is not having to touch original classes for solve very specific cases.
Besides, I'm sure that Antonio has take note of your request for retouching TGet accordantly in a future FWH release.

Unfortunately no (at least up to my version 8.02), we hope that the Harbour's people to implement it soon.
Best regards.

Otto,
Is there a reason that you are not using xHarbour for everything? I use xHarbour exclusively.

Hello James, hello Manuel,
Thank you for your help.
No there is not really a reason why I use both.
I tried to insert the method in TGet. I think it should only work on Gets with spinner. Therefore I inserted the proof for lSpinner.

Otto
METHOD MouseWheel( nKeys, nDelta, nXPos, nYPos )
IF ::lSpinner=.t.
If nDelta > 0
Self++
Else
Self--
EndIf
ENDIF
Return Nil
