To define icons and
overlay conditions, these steps were taken:
| 1.
|
For the Tree View object, on the Visual tab page, set Show
Icons to Yes. |
| 2.
|
For Tree View Node 1, on the Visual tab page, set Image
to: |
C:\Program
Files\USD70\BITMAPS\primkey.ico
| 3.
|
For Tree View Node 2, on the Visual tab page, set Image
to: |
C:\Program
Files\USD70\BITMAPS\column.ico
| 4.
|
For Tree View Node 3, on the Visual tab page, set Image
to: |
C:\Program
Files\USD70\BITMAPS\transpar.ico
Setting the Image property is
obligatory when you define an overlay image. The transpar.ico image
is not visible but there can be another image superimposed on
it.
| 5.
|
For Tree View Node 3, on the Behavior tab page, set Overlay
Condition to: |
SELECT 'overbooked'
FROM dual
WHERE :max_part <
(SELECT
COUNT(*)
FROM participant
pt,
reservation
r
WHERE
pt.res_id=r.res_id
AND
r.schedtour_id=:SCHEDTOUR_ID)
This condition checks if the
current Scheduled Tour is overbooked.
