Expression & Table

Question

Hey,

With the new Expression data type in a column, a customer asked me if it is possible to have a button which will do an action when we click?

It seems that Expression is directly linked to JSL, so the question makes sense.

If yes, does anybody have an example?

Thank you,

Florence

No, not a button, not in JMP 12.

There are two reasons it can't work right in JMP12: the buttonbox won't get created by the host as a button, and other boxes that might respond to clicks won't get the click (the click goes to the data table cell to be handled by the table, not the content of the cell).

very little, if any, testing was done on storing displayboxes into expression columns.  It won't work right.

Look at the example Jeff pointed to for what currently works.

Where does the customer want this button that will do something when he clicks?

We have some examples where selecting a row, by clicking on a point in a graph, for example, performs some action.

This is done using the Selected() function in a formula column. The attached data table is an example.

Interesting question. I tried this out and as far as I can tell, you can store an expression that will create an actionable button in a table cell, but the cell will not render the button (e.g., you get code, but nothing else). If there's a way to create a working button in a table cell, I'd be interested in knowing how to do it.
