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

Hi,

Declare a global variable in TOP include as gv_pb_text(20). And then have one push button in the screen with name gv_pb_text and then mark it as Output only.

In your PBO, fill gv_pb_text based on your conditions,

IF gv_button_clicked EQ 'X'.

gv_pb_text = 'Start'(001).

ELSE.

gv_pb_text = 'Stop'(002).

ENDIF.

In your USER_COMMAND Module in PAI (or whatever your Fcode handling module is),

WHEN 'STARTSTOP'. "Assuming this pb's function code

IF gv_button_clicked EQ 'X'.

CLEAR gv_button_clicked.

ELSE.

gv_button_clicked = 'X'.

ENDIF.

Hope this helps..

Hi!

There is a simple way to do this:

1. Add a button with the screen painter and name it perhaps "HARRY".

2. In the properties set the button to "Output"

3. Create a variable in TOP or somewhere else which is also named "HARRY" perhaps by "DATA: HARRY(16) TYPE C."

4. Change HARRY to contain something by "HARRY = 'harry'." in the PAI.

Here is the sample coding

REPORT z_dietzha_test_000000000000085.

DATA: testbutton TYPE c, okcode TYPE syucomm.

CALL SCREEN 0100.

INCLUDE z_dietzha_test_00000000000085i.

***INCLUDE Z_DIETZHA_TEST_00000000000085I .

MODULE user_command_0100 INPUT.

IF sy-ucomm = 'EXIT'. LEAVE TO SCREEN 0. ENDIF.

IF testbutton = '1'. testbutton = '2'. ELSE. testbutton = '1'. ENDIF.

ENDMODULE.

And in the screen 0100 the TESTBUTTON has the field "Output" checked in the "General attr." tab.

Mattias,

It can be done!!!!

I am assuming u have screen 100.

Intially the text will be 'START' in the button and when u press that button, It should change to STOP???

Idea:

1. Create only ONE Button in the Screen 100.

2. Name the button as BUTTONNAME and assign a FCODe

as 'PRES'.

3. In the main program, have

data: buttonName(20).

4. Have a FLag

data: clicked type c value 'N'.

5. In the PBO.

If clicked eq 'N'.

buttonName = 'START'.

else.

buttonName = 'STOP'.

endif.

6. In the PAI.

case okCode.

when 'PRES'.

clicked = 'Y'.

.............

when others.

leave program.

endcase.

This could help and it is not a good programming practice. Instead , have a Second Screen 200(just a copy of Screen 100). When u press START in screen 100, get the okCode and call Screen 200(having STOP Button). When the User press STOP in Screen 200, u could Stop the transaction or leave the program.

Thanks

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
