Making a Form with a Scrollbar?

thewill2live
I was reading through the Allegro SKILL Reference guide and noticed that VARIABLE formtypes are not supported. Is there some other way I can make a form with a scrollbar? I need to display alot of text and the window extends outside of the visible part of the screen (so that the bottom buttons are off screen). Is there a way to get a scrollbar into the form so that the text scrolls instead of making a huge screen? 
  • STRFILLIN fields will scroll if the text is larger than the field length

  • Like eDave suggests use a STRFILLIN  with the multiline option. The following form file snippet will create a 16 width by 10 high control with a vertical scrollbar that will support up to 1024 characters. Using the FSIZE parameter is what allows a taller control. If you do not wish to let the user edit the string mark the control as read-only in your Skill code (user will still be able to manipulate the scroll bar).

        axlFormSetFieldEditable(fw "mline" nil)

    When loading the field use the newline ("\n")  to force text to break to another line.

    FIELD mline
FLOC 16 6
STRFILLIN 16 1024
FSIZE 16 10
ENDFIELD

     

     

  • Thanks guys, but I think I was a little vague when I explained my issue. Here's a more in depth explanation. I have a list of entries that I am outputting to a file and want to show it on a form before I actually write the file so that the user could make any adjustments desired. My issue was that if the amount of text that prints out happens to be 60 lines or something like that, I wanted it to scroll in the screen instead of extending the screen (because at that point the screen could extend past the visible area). So the option I ended up going with was making a Grid. Because putting a grid seems to automatically put in scroll bars in the vertical and horizontal directions. This is working out for me on this project but thanks again for your suggestions because they ended up being useful for another program that I'm writing.
  • Do you happen to have a code snippet for this? I'm trying to do the exact same thing with little luck. I'm fairly new to using Grids. All I need is a single cell that allows for displaying and editing multi-line text. Any help is GREATLY appreciated! -Mike

  • Am I even getting close here?
    Thanks! -Mike

    procedure( _scInitGrids()
    let((c cell )

    c = make_formGridCol()
    c->fieldType = 'STRING
    c->colWidth = 2
    c->align 'left
    c->headText = "Text"
    axlFormGridInsertCol(checkForm "grid" c)
    axlFormGridInsertRows(checkForm "grid" 1 1)

    cell = axlFormGridNewCell()
    cell->row = 1
    cell->col = 1
    cell->noEdit = nil <==================== Doesn't seem to let me edit the cell.
    cell->textColor = 'black
    cell->value = "Layer"
    axlFormSetField(checkForm "grid" cell)

    axlFormGridUpdate(checkForm "grid")

    );End let.
    );End _scInitGrids().
