* @brief
* 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.
*
