change button text dynamically

[Former Member]

hi,

Situation:

I have a 2 Buttons on a dynpro, which are labelled <i>start</i> and <i>stop</i>.

Aim:

The aim is to have only one button, which changes the label when pushed.

Question:

is there a way to change the text on a button (on a dynpro) dynamically? (I don't talk about GUI-Status Buttons).

Regards,

Matthias

JUST CREATE TWO BUTTONS.

1. START

2. STOP

NOW..

wriite a module <b>loop_screen</b> at pbo. here you set one button visible, another invisible, depending o condiion.

i am just giving you one report program..where the selection screen get changed dynamically.

you can use the code of the <b>modify_screen</b> perform in your <b>loop_screen</b> module

run this code..and select radio buttons, see the screen change

for better understanding..just create 3 text-element, before running this code.

text-100 = COPY

text-200 = MOVE

text-300 = DELEET

report zxx.

Hi Anid again,

right now I am using 2 buttons, which in fact i show/hide during pbo loop at screen.

The problem with this is, that i can't place the buttons in the same place (same screen coordinates).

btw, i am on a dynpro in the layout-mode of screen painter, where I set up the butts.

If I can use 2 butts lying above each other or manipulate the label, when using only one, I shall be close to perfect.

Ya.i can understand the problem

but you can't put one object (here BUTTON) over another in screen painter.

visible/invisible is the solution as per my idea.

one cumbersome method is..(funny, stil it works)

1. just keep one button in that screen(100 say)

2.create a duplicate screen 200 with one button, the lable being different.

3.now call appropriate screen depending on condition, for better look and feel.

cheers
