Hi!
I designed a window with a single choice list of 3 elements, and abutton"OK" at the bottom of the window. If the user clicks on an element ofmysingle choice list, everithing works fine. But if he positions thecursor on
an element of the list and then push the OK button, my program does not
receive any selection. I also tried to use the CHCCTL to get theselectionbut it does not work if the user hightlights an element of my list andthen
push the OK button...
Any suggestion to get the item that is highlighted when the user pushthe OK
button?

Here's a short piece of my display file code:
A F12 2Y 0B 6 8SNGCHCFLD(*RSTCSR *AUTOSLT*NOSLTIN-
A                                      D *AUTOENT)
A                                      CHOICE(1 'Choice 1')
A                                      CHOICE(2 'Choice 2')
A                                      CHOICE(3 'Choice 3')
A                                      CHCCTL(1 &FLD03)
A                                      CHCCTL(2 &FLD04)
A                                      CHCCTL(3 &FLD10)
A            F13            2Y 0B 10 32PSHBTNFLD
A                                      PSHBTNCHC(1 'OK' ENTER)
A            FLD03          1Y 0H
A            FLD04          1Y 0H
A            FLD10          1Y 0H


You can't do what you are trying to accomplish with this definition.

Firstly, CHCCTL only indicates a selected value for MLTCHCFLD fields.For SNGCHCFLD the CHCCTL only sets whether available or not. F12 willcontain the number of the selected field. If you want to indicatepre-selected fields then for SNGCHCFLD you have to set the real fieldvalue (in this case F12 to 1). For MLTCHCFLD you set the various CHCCTLfields instead.

Secondly, the reason clicking OK doesn't indicate a selection isbecause no selection was made. You moved the cursor to an item and itwas reverse-imaged to show you where the cursor is but that item is notselected. It won't be selected until you press the space bar (or clickthe item with the mouse) at which point it will change fromreverse-image to highlight. Because you have defined *AUTOENT the actof selecting also issues Enter and the user never gets a chance toclick OK.

If you remove *AUTOENT then the user can click the menu item to selectit (or move the arrow keys and press the spacebar) and then click OK tosend the selection to your program. They will have to use two mouseclicks to accomplish this. They will no longer be able to automaticallyselect and submit using a single mouse click however if you enable"ENTER at cursor position" in "Hotspots Setup" in PC5250 thendouble-clicking an item will select it and send Enter to theapplication.

*AUTOSLT will still allow selection by moving the cursor and pressingEnter because *AUTOSLT means automatically select the item if thecursor is on the item when Enter is pressed.
