I have a table that lists around 100 tanks and select data for each. On the screen I have a “Tank Search” box that can use either the tank id or a lot id. The functionality works to find and select the row for the found tank. What I would like to do is have the code show the selected row as well. As it stands now, the selected row may be above or below the currently displayed rows in the table. Is there a way to have this logic “auto scroll” to display the found and selected row? ---

Bump. Looking for the same thing. I understand you can do it with a JTable, but I don’t know how to get a JTable from an Ignition table. At least, it doesn’t work with a List Table. This would work if that getTable() reference worked… ```auto myJtable = list.getTable() rectangle = myJTable.getCellRect(rowNum,0,0) myJTable.scrollRectToVisible(rectangle) ``` ---

The JList is a bit more involved to retrieve. Try this in the property event script. ```python if event.propertyName == "selectedIndex": jList = event.source.getViewport().getComponent(0) jList.ensureIndexIsVisible(event.newValue) ``` ---

Hey Jordan, I tried that and got an error, object has no ensureIndexIsVisible. When I do a dir on the jList object, that method is not in the results. I do see it in the java docs for the JList object though. ---

Let’s back up a sec. I may be confused on what you’re using. Correct me if I’m wrong, but: @MikeAllgood is using a table @boyergary is using a list. The first script I posted (above) is for a list. For a table (also in the property change event): ```python if event.propertyName == 'selectedRow': jTable = event.source.getTable() rectangle = jTable.getCellRect(event.newValue,0,0) jTable.scrollRectToVisible(rectangle) ``` ---

I think there is some confusion here. Are you actually wanting a marquee type of display? ---

This may be more what you're looking for. > [@How to make scrolling LCD Display (marquee)](https://forum.inductiveautomation.com/t/how-to-make-scrolling-lcd-display-marquee/3336/18): > > Here’s an update on Jordan’s marquee using system.gui.transform. It’s simpler and doesn’t need as many objects or bindings. Just set the root container’s time property to the length of time in milliseconds for the message to cross the container. It should cope with different length of container or message. Multiple messages is left as an exercise for the reader.
