The order of the images determines when they are used:

1. Default overall bitmap or icon: always used with any listed entries that do not

have subordinates.

2. Default bitmap or icon for items with subordinates.

3. Default bitmap or icon for items with subordinates if the tree level is expanded (i.e.,

shown) in tree view.

4. Bitmap or icon for entries that do not have any subordinates when the item is selected.

5. Bitmap or icon for entries that have subordinates when selected.

6. Bitmap or icon for entries that have subordinates when selected and level is expanded.

Note: If images are set up for individual elements in tree view LIST_BOX LOAD and WRITE

statements, these will override the default FMT= images for the individual element. For

Example Tree View

0010 LIST_BOX 10,@(5,5,25,10),OPT="e|",

0010:FMT="{!diskette|!File|!File_open}",SEP=DLM

0020 LET F=1,D$="."

0030 NXTDIR:

0040 SET_PARAM 'SD'=1

0050 OPEN (F)D$

0060 NXTFILE:

0060:READ (F,END=ENDDIR)F$

0070 IF F$(1,1)="."

0070:THEN GOTO NXTFILE

0080 IF MID(F$,-1)<>DLM

0080:THEN LIST_BOX LOAD 10,0,PTH(F)+DLM+F$;

0080:GOTO NXTFILE

0090 LET D$=PTH(F)+DLM+F$

0100 F++

0110 GOTO NXTDIR

0120 ENDDIR:

0120:CLOSE (F)

0130 F--

0140 IF F>0

0140:THEN GOTO NXTFILE

0150 ESCAPE

Tip: Use SEP=DLM when reading directories to have ProvideX append the operating

system delimiter to subdirectory names.
