LineEdit is a subclass of QLineEdit that provides an easy and simple
|
|
way to add widgets on the left or right hand side of the text.
|
|
|
|
The layout of the widgets on either side are handled by a QHBoxLayout.
|
|
You can set the spacing around the widgets with setWidgetSpacing().
|
|
|
|
As widgets are added to the class they are inserted from the outside
|

into the center of the widget.
