Detailed Description

Like NumSlider, but on shift-LBDown lets you type in a value.

This is simliar to the control in the program Blender. The current value is made the starting value of the LineEdit. If there is a parsing error, then the original value is not changed. If a number is entered, but it is out of bounds, it is clamped to the range [min,max].

Todo:

Double click should also jump to edit. A single normal click will inc or dec the value, and the double click should revert to previous value before entering the edit.
