Adding Mouse-Over Ability to HTML Trees

To add mouse-over ability to HTML tree elements, you must add fields to the TREECTL_HDR_SBR record and PeopleCode to the program to set the values and the images.

1. Add the following fields to the TREECTL_HDR_SBR (tree control header subrecord) record.

   • COLLAPSED_MSGNUM

   • COLLAPSED_MSGSET

   • END_NODE_MSGNUM

   • END_NODE_MSGSET

   • EXPANDED_MSGNUM

   • EXPANDED_MSGSET

   • LEAF_NODE_MSGNUM

   • LEAF_NODE_MSGSET

2. Add the following PeopleCode to set the message set and number for the mouse-over text:

   &REC.GetField(Field.EXPANDED_MSGSET).Value = 2; 
   &REC.GetField(Field.EXPANDED_MSGNUM).Value = 903; 
   &REC.GetField(Field.COLLAPSED_MSGSET).Value = 2; 
   &REC.GetField(Field.COLLAPSED_MSGNUM).Value = 904; 
   &REC.GetField(Field.END_NODE_MSGSET).Value = 2; 
   &REC.GetField(Field.END_NODE_MSGNUM).Value = 905; 
   &REC.GetField(Field.LEAF_MSGSET).Value = 2; 
   &REC.GetField(Field.LEAF_MSGNUM).Value = 906;

3. Add the following fields to the TREECTL_NDE_SBR record:

   • DESCR_MSGNUM

   • DESCR_MSGSET

4. Add PeopleCode to set the DESCR_MSGNUM and DESCR_MSGSET fields.

   These two fields should be set to the correct message number and message set values that contain the text to be used as the mouse-over text.
