A control that combines two scrollbars for choosing two related values

<!------------------------------- STEP 3 ---------------------------><!-- Add the article text. Please use simple formatting (

If you want to give the user the possibility to define a number interval to set a two side threshold in an image processing program, then you can use two scrollbars, first for lower and second for upper limit. Further you have to catch changing events to prevent that lower limit is higher than the upper.

Wouldn't it be easier to have a control that combines two scrollbars?

The ZzzzRangeBar is a two button slide control for setting an integer number interval. If you push with a left click on a slide button it will marked and while mouse button is pressed you can move the slider left and right. Otherwise you can use the keys + and - to manipulate the slider position.

The control will throw two events. While left mouse button is pressed and the position of one slider has changed the event OnRangeChanging will generate and if you release mouse button, the event OnRangeChanged signals program that a new range was selected.
