PolyList and Image data

[pink]

I am trying to use the PolyList widget, however I cannot get the image-data to display.

This is very simple setup... I have a PolyList that only has the item "image" which is set to the content type of "image-data". There are 2 images in the card that I am testing with.

I have the following button set to add the imageData to the Polygrid. The data is in the array, but nothing is being displayed.

Code: Select all

on mouseUp
   put the imageData of image "a1" into tData[1]["image"]
   put the imageData of image "a2" into tData[2]["image"]
   set the dataContent of widget "PolyList" to tData
end mouseUp

Because the images make the file too large, I can't attach, so here's my test stack: https://u.pc.cd/qsM

Any thoughts as to what I'm missing?

Hi Greg,

putting "the imagedata" of an image into another image requires that both source and target image have the SAME dimensions (height and width).
Otherwise it will not work andI think this also applies to "PolyList" widgets.

So I added 128x128 images to the stack, and set the size of the item (Columns tab) to 128x128, and the item height of the item to 128 and the width of the column to 128.

Still no luck.

also trying to fool around with the PolyGrid with the same results

Hi Greg,

I tried your example stack: no luck.

Out of "desperation" and a little suspicion* I changed "imageData" to image:

Code: Select all

on mouseUp pMouseButton
   put image "a1" into tData[1]["image"]
   put image "a2" into tData[2]["image"]
   set the dataContent of widget "PolyList" to tData
end mouseUp

That worked. Your images are shown in widget "PolyList"
I tested your second stack and for PolyGrid it is the same.

Who would've thunk?

Kind regards
Bernd

* suspicion because there are other instances in the terminology of Poly-Grig/List that are "strange"

thanks Bernd, I wouldn't have thought of that

Also, just so it is listed somewhere, the size of the item/column/row DOES NOT have to be the same as the image being put into it.

The content fit of the item (fill, cover, or contain) will fit the image regardless of the size of the original.

AHA!

Thanks for the info!
