Calculator in Module Pool

[Former Member]

Hey i have designed a Calculator in Module pool. I have created a Screen with Buttons and other functionalities.If you Give input from Mouse by Clicking on desired button Everything is working fine .But Instead of clicking on these button i want input has to be given from keyboard itself .For example

Press 1: 1 Should be appear on Screen

Press + : It should not appear on Screen.

Press: 2 : It should Appear on Screen.

If you Press Enter Final Added Value should appear on Screen.

Is Keyboard interfacing possible with Custom developed Screen ? If possible please reply .

To develop Calculator in Module Pool program Instead of you can use FM FITRV_CALCULATOR. But I dont know the Keyboard Interaction.

Report ZCalculator.
DATA: OUTPUT_VALUE(15) TYPE C.

call function 'FITRV_CALCULATOR'
  IMPORTING
    OUTPUT_VALUE               = OUTPUT_VALUE
  EXCEPTIONS
    INVALID_INPUT              = 1
    CALCULATION_CANCELED       = 2
    OTHERS                     = 3.

See Calculator is working Fine if you provide inputs from Mouse by clicking on push buttons . But My intention is can i provide inputs from Keyboard without touching mouse.

As in microsoft calcuator we can given input frm keyboard itself and check output. Please reply

Did you define a proper input field for entering your data? Sure it is possible to use the keyboard as input. This is the same for custom fields as it is for your Standard SAP fields.

Hi,

Not sure if this helps for your actual question. But, How about reusing the Windows calculator instead of redesigning on your own? (I am assuming your operating system is Windows. In case of others, you can pass appropriate command name).

CALL FUNCTION 'GUI_RUN'
  EXPORTING
    command          = 'CALC'
*   PARAMETER        =
*   CD               =
* IMPORTING
*   RETURNCODE       =
          .

Thanks,

Vinod.

hi,

you can assign a function code to that push button as well.

so you dont require mouse input.

I didnt Understand how will you define function code so that it will pick input from keyboard itself.In PAI event we can check inside Case Statment for different FCODE . Will you please Elaborate this concept.

hi,

oops my mistake.

insted of function code i meant function key.

you can assign a ufnction key to the push button on the screen.

so even if the input comes from the keyboard or the mouse, the PAI event

will still be triggered.
