Module Combo_mx.pkg

1/31/2002 JJT - Trim search text in WinCombo_item_matching (trailing spaces caused problems in search) 12/13/2001 JJT check Oem_translate_state before making translations. Fixed combo_delete_item (if combo is active and sorted, it works) 8/2/97 JJT Made item_changed_state in combo_edit_changed unconditional. (DFCentry.pkg modified to forward to combo_edit_changed and combo_item_changed) 06/13/97 JVH Modified Combo_Edit_Changed so that it sends OnChange. It looks like it used to do this and was commented out (don't know why). 04/01/97 JJT Fixed all OEM to ANSI / ANSI to OEM problems

  • booleanOnDropKey(integer iVKey boolean bIsAccelerator)
    The following three messages are designed to handle accelerator key handling when a list is dropped down. When a list is dropped, we want all accelerator keys to be ignored. In addition, we want the return and enter keys to roll the list up, if return is pressed the value should be updated Called by key and Process_Accelerator when a list is dropped down and a key is pressed. We pass the virtual key (not the df key) and a flag telling us if this is an accelerator key (Tells us where it was called from) Return: True if you, want to stop any other actions. Currently this looks for return and escape.
    • Integeri
    • IntegeriItem
  • Process_Accelerator(integer i1 integer i2)
    note that we must test for both process_accelerator and Key because we don't know if a key (e.g. esc=kCancel) has been assigned to on On_key or not. If an on_key, process_accelerator is called, else Key is called augment to check for keys pressed in dropped state. Most likely, when dropped we will trap esc and return and ignore all others
    • IntegerbDropped
    • IntegeriVKey
    • IntegerbDone
  • integerKey(integer iKy)
    augment to check for keys pressed in dropped state. Most likely, when dropped we will trap esc and return and pass all others through
