/**
|
|
* @short Line edit widget with extra drag and drop options.
|
|
*
|
|
* The LineEdit class is a line edit widget which accepts specified types of drag and
|
|
* drop content.
|
|
*
|
|
* The widget will always accept drag and drop of text, except text/calendar mime type,
|
|
* and of URLs. It will accept additional mime types depending on its configuration:
|
|
* Text type accepts email address lists.
|
|
* Email type accepts email address lists and VCard data (e.g. from KAddressBook).
|
|
*
|
|
* The class also provides an option to prevent its contents being selected when the
|
|
* widget receives focus.
