Q: "thanks for your reply, I tested and I have the following message "alert. Nothing to display".
I have several colums labelled."
A: This is because it picks up the first labelled column it finds to build a data filter. I just found out that this approach does not work for picture columns. A simple solution is to open the table and reorder the columns so that the first label column from left to right has a categorical or numerical type. I will code something more robust later. Once the LabelViewer window is up you can change the filter.
Q: "Question: Is the hover label editor (than I discover with your message) able to look for a photo in a folder of photos (*.jpeg), to put it inside the hover label for the correct line. It will be more simple and it will avoid a database too big."
A:Yes. It can even fetch pictures from a web site. But that needs a bit of JSL. There is an example showing how to get images from Wikipedia here:
Documentation is here:
A simple example of displaying an image from disk would use the Picture attribute of the Set Graphlet command to build the image file name from the execution context (which includes the values of the labeled variables), open it and pass the result to a PictureBox, like so:
Set Graphlet(
Picture(PictureBox(Open( cwd || local:_Species || ".jpg", "jpg"))),
Click(Web( "file://" || cwd || local:_Species || ".jpg" ))
)
Please see the attached IrisLocalImages.zip for a complete example.
