QUESTION
I am writing a JavaFX app where a series of messages appear in a TableView. When a new message appears, its row in the table should be highlighted, meaning its background color should be orange or something. Once the user clicks it, the background color should clear, acknowledging the message was read. Should be simple.
I've done enough research to realize that I need to use a rowFactory to set or clear a row's background. But I'm struggling with the mechanics of setRowFactory()
. The documentation on Oracle is over my head, and every example I pull up online seems radically different than the last one.

s are created by TableView
to fill it's viewport and contain TableCell
s. At the time they are created the item

. You could register a listener to that property but usually I prefer overriding the updateItem
method of a cell.
Also using PseudoClass
is simpler than using style classes. New items can be assigned to a row; this could result in the same style class being added multiple times and even both style classes could be added to the same cell. PseudoClass
es however can be switched on/of without the need to take care of removing other classes.

I have this two methods that in the first look are fine.
But the problem is that e parameter of RadWizard2_NextButtonClick
method is returning the value of e parameter of radTxb_TextChanged
method.
I tried to change the name of e
parameter in one of the methods but than returns me null
all the time when in fact it should not.
Any idea why this is happening or where i am doing wrong??

This application needs to be able to start and stop a periodic heartbeat message before and after various other user initiated tasks. Using @Matthew's Monitor class as an example, there is no periodic Heartbeat message sent
printed when starting the message or indication that the message is being sent. There is also no error message indicating why the periodic task has not started - just the print messages for opStartHeartbeat and opStopHeartbeat. What is missing?
