/*! \brief The DoubleValueField class provides to view an object to manage a
generic double parameter, with two
cipher after decimal point.
Inherits \b QWidget.
The class is composed of an horizontal layout which contains two
object,
\li a vertical layout with a text field \b PrimaryDoubleLineEdit
and a roller
\li an horizontal slider QSlider.
This objects are connected, so if you change one the other
automatically change.
It's possible to set current value getValue(), minimum and max
value, getRange(),
using setValue(), setRange() or setValues(); by default value =
0, minimum
value = -100.0 and maximum value = 100.0.
\n Maximum height object is fixed to \b DVGui::WidgetHeight, while width
depend
on parent width.
To know when double parameter value change class provides a
signal, valueChanged();
class emit signal when slider value change or when editing text
field is
finished and current value is changed. Editing text field
finished may occur
if focus is lost or enter key is pressed. See SLOT:
onSliderChanged(int value),
onEditingFinished().
