openedge - Which event should be applied to the combo-box in prorgress 10.2b, so that it drop down -


which event should applied combo-box in prorgress 10.2b, drop down. default, cursor down, need open space, , can not figure out how it.

i've managed creating selection list that's copy of list-items in combo-box.

here's code. assume combo called c , frame called f. works if have widget directly under combo.

def var hsl handle no-undo.  /* mandatory variable definition in program */  on ' ' of c do:     create selection-list hsl        assign frame      = frame f:handle               col        = c:col in frame f               row        = c:row in frame f + 1               list-items = c:list-items in frame f               visible    = yes               sensitive  = true        triggers:          on return persistent run pichoose.          on leave persistent run pileave.        end triggers.     apply 'entry' hsl. end.    procedure pichoose:    assign c:screen-value in frame f = hsl:screen-value.    assign c.    apply 'leave' self. end procedure.  procedure pileave:    delete object hsl no-error. end procedure.

note if you're using list-item-pairs, list-item-pairs attribute should used i'm using list-items.

hope helps!
