The effect that I’m looking for is one in which a Combobox appears as a simple Label displaying a string. However, when the user mouses over the “Label”, the dropdown control appears; at this point you can see that the control is indeed a ComboBox.
When the mouse exits the control, the dropdown control fades away and the CombBox looks like a Label control again.
I’m sure I can work this out on my own, but if JUCE already has a way of doing this, or if there is a tried and true technique I’d like to use it. No sense in re-inventing the wheel.
