Detailed Description

This widget allows you to use a slider with a lineedit in a Dialog Box. The [min,max] interval is divided by 100 line steps (10 page steps), the slider controling the variation in percentage.

1 label is used to give the parameter a name (default is objectName())

Your own initialization: in YourDialog class,you can init a SliderTextWidget using setText(..) and init(..).

In line edit, if the value is superior or inferior than the initial bounds, the bounds are automatically updated.
