This is a nice feature, but without a text box users have to actually click on a slider before they can see its value. In most cases it means they will actually change the current value in the process. Is it possible to have it display on a mousEnter, without having to hack a lot of Slider code?
It could be done, but the Slider class is already pretty bloated with functionality and I'm not too keen to add more small options like that. It could probably done with a subclass?
I use a toolip to show the value on mouse over.
In the end I just used a BubbleMessage component and few mouse listener methods. Working wonderfully well. No need for any hacking of Sliders.
