I have written a new custom control and commited it to the ControlsFX project. It is a highly specialized control for showing a list of background tasks, their current status and progress. This is actually the first control I have written for ControlsFX just for the fun of it, meaning I do not have a use case for it myself (but sure one will come eventually). The screenshot below shows the control in action.
If you are already familiar with the javafx.concurrent.Task class you will quickly grasp that the control shows the value of its title, message, and progress properties. But it also shows an icon, which is not covered by the Task API. I have added an optional graphics factory (a callback) that will be invoked for each task to lookup a graphic node that will be placed on the left-hand side of the list view cell that represents the task.
A video showing the control in action can be found here:
