Importing and displaying images

[Gautami]

Hi all,

I am trying to import about 100 pictures from a folder and displaying them in thumbnail size in a datagrid.
I edited the template stack and put in this codes.

In the button:

Code: Select all

     
 put specialfolderpath("desktop") &"/images" into tfolder
   set the defaultfolder to tfolder
   put the files into theDataA
   filter theDataA without ".DS_Store"
    
    repeat for each line xline in theDataA
       put quote & tfolder & "/" & xLine & quote & return into theDataA[xline]["Image URL"]
   end repeat

And in the row template

Code: Select all

on FillInData pDataArray
   set the filename of image "image" of me to pDataArray["Image URL"]
end FillInData

The problem is that nothing gets displayed, only an outline of the image field.

Thank you and any help will be appreciated!

Cheers,
Gautami

HI Gautami,

well, you have QUOTES and a RETURN (!) in the filenames, remove them and it should work:

Code: Select all

...
repeat for each line xline in theDataA
   ## THIS produces a valid filepath:
   put tfolder & "/" & xLine into theDataA[xline]["Image URL"]
end repeat
...

Hey Klaus,

I tried and still I get a blank datagrid.

Is there any other way I could get the user to import pictures from a folder
and display them??

Ah, I think I got it!

When creating the array for the datagrid you use the FILENAMES of the images as the keys,
but the keys need to be NUMERIC -> 1 - N!

Code: Select all

...
## We need to create numerical keys for the datagrid array!
put 1 into tCounter

## xline will hold the filename of the images!
repeat for each line xline in theDataA
     put tfolder & "/" & xLine into theDataA[tCounter]["Image URL"]
     add 1 to tCounter
end repeat
...

Best
