Virtual Keyboard

Euclides · Post by **Euclides** » Fri Dec 05, 2008 12:05 pm

Hi to all.
I am implementing a Virtual Keyboard in a routine using:
oGet:SetFocus(), oGet:KeyChar(nKey)
Character fields works well, even together with the regular keyboard.
With numeric field with a PICTURE, it only keeps the last number entered.
TIA for any sugestions.
Regards, Euclides

Euclides,

I'm not sure exactly what you are doing, but nKey is the last key entered.

Are you using oGet:varGet() to get the contents of the field?

Regards,
James

Hi James,
Mainly i am doing the following:

cNr=space(10); nNr=0
REDEFINE GET oGet[1] VAR cNr ID 102 OF oDlg1
oGet[1]:bGotFocus:={|| nX:=1 }
REDEFINE GET oGet[2] VAR nNr ID 101 OF oDlg1 PICTURE "@E 999.99"
oGet[2]:bGotFocus:={|| nX:=2 }
REDEFINE BUTTON ID 10 OF oDlg1 ACTION ( oGet[nX]:SetFocus(), oGet[nX]:KeyChar(asc("0")))
REDEFINE BUTTON ID 11 OF oDlg1 ACTION ( oGet[nX]:SetFocus(), oGet[nX]:KeyChar(asc("1")))

The character field fills OK but the numeric field overwrites the whole field with the number typed
I planned to use the TGET class methods to build the numbers.
Thanks for jumping in, regards.

Euclides,

Try oGet:keyDown( nKey ) instead.

James

James.
oGet:keyDown( nKey ) has no effect.
To to simulate the "Enter" key I must use:
REDEFINE BUTTON ID 24 OF oDlg1 ACTION ( oGet[nX]:SetFocus(), __Keyboard(chr(VK_RETURN)))

Euclides,

The simple solution is to define the numeric field as character:

nNr:="000.00"

Then convert it to a number afterwards.

James

Yes James.
I did it this weekend. I intended to use the TGET methods to do the job.
I almost had to do a separate routine for each field.
Thanks & Regards.

Euclides,

I'm not sure what you did. You only needed to change the intitialization of the numeric vars to character from 0, then convert them to numeric when you save the data. You only need one extra line of code for each numeric var, e.g.

nAmount := val( cAmount )

It is a little extra code, but you don't need a routine for each var.

James

Euclides,

I found this sample in SAMPLES:

Hi Rochinha,
I started my project from KEYBSIM.PRG from the SAMPLES folder.
My problem was with numeric fields with decimal places so i built specific routines to treat character by character and some checkings. (do not let the user type twice a decimal point, etc)
Thanks & Regards
Euclides

Euclides,

You don't need all that if you simply use a numeric picture clause and define the default variable as character.

cVar := "000.00"

REDEFINE GET...PICTURE "E 999.99"

This will prevent two decimals, characters, etc.

Regards,
James

function Main()
// ---------------------------------------------------------------------------------------------
    LOCAL cNr := space(10)

    LOCAL oDlg, nx
    LOCAL oGet := {NIL,NIL}



    SET EXACT OFF
    SET DELETE ON
    SET DATE GERMAN
    SET CONFIRM OFF // ON
    SET TYPEAHEAD TO 100
    SET EXCLUSIV OFF
    SET DECIMALS TO 2
    SET EPOCH TO year( date() ) - 80
    SET CENTURY ON


    DEFINE DIALOG oDlg TITLE "Test Num Get" SIZE 300, 300  PIXEL TRUEPIXEL


    @ 30, 8    SAY "Get 1"              PIXEL OF oDlg
    @ 30, 160  GET oGet[1] VAR cNr      PIXEL OF oDlg  SIZE 100, 25
    oGet[1]:bGotFocus:={|| nX:=1 }

    @ 60, 8    SAY "Get 2"              PIXEL OF oDlg
    @ 60, 160  GET oGet[2] VAR nNr      PIXEL OF oDlg  SIZE 100, 25 PICTURE "@E 999.99"
    oGet[2]:bGotFocus:={|| nX:=2 }

    @ 100, 50   BUTTON "Get 1"  OF oDlg size 50,30  PIXEL ;
             ACTION ( SetFocus(oGet[nX]:hWnd), oGet[nX]:KeyChar(asc("0")))
    @ 100, 120  BUTTON "Get 2" OF oDlg size 50,30  PIXEL ;
