Pushbutton on screen visible/invisible

[Former Member]

Hi,

on a scree there is a push button. The screen can be started by 2 ways, once the push button should be visible, once it should be invisible.

If I start the screen THE FIRST TIME the pushbutton is shown and if I change the view to the situation without the push button, the button disappears. I can switch back to the situation where the push button is shown. Everything ok.

But if I start the screen THE FIRST TIME in the situation where the push button is invisible and then if I switch to the situation where the button should be shown, it is not visible.

Technically I use loop at screen with modify and I set the variables active, input, output and invisible concerning and respecting correlations between these variables (compare documentation).

Has anybody an idea?

IF you are using a module pool program you can declare a global flag, to determine how the screein called.

data: flag(1) value 'Y'.

say the screen 100 (which is having the pushbutton) is called in such a way, that button should be visible.

then set

flag = 'Y'.

this should be done before , call screen 100.

similarly if screen 100 is called in such a way that the button should be invisible then

flag = 'N'.

call screen 100.

now in PBO of screen 100, create a Module Modiy_screen.

here you write the code..as

loop at screen.

case flag.

when 'Y'.

modify scren to make button visible.

when 'N.

modify scren to make button invisible.

endcase.

modify screen.

endloop.

i think you alreday done in such way, just see, if the flag is set properly.

HI Anid,

thanks for the answer. The switch from "invisible button" to "ivisible button" is done by F4-Help. So in this step (PAI) the modify screen is done to make the button visible and no PBO is called again (because of F4-Help).

Could this be the problem?

Fest regards!

ya thats the problem even i think..

the modiy-screen statement are supposed to be in a PBO module , instead of PAI.

just clarify one thing...

r u asking for ..

if the user select a value from F4, make the buttn invisible, and if he selects some other value make the button visible.

is this the thing you want to implement??

[Former Member]

Yes this is what I mean.

I think now I have the solution. I call "LEAVE TO SCREEN XXXX" after f4-help and the PBO is called again and the button is visible.

It is interested that the input/output variables after F4-help calling modify screen (in PAI) are functining but not the visible/invisible.

Thank you very much for your help!

Florian
