+/**
+ * @brief The LtsDialogButtonBox class is a replacement for the NGLDialogButtonBox. With the significant difference that
+ * Actions ('Ok', 'Close', etc.) are select in code, not in the designer.
+ *
+ * Pro:
+ *  > no dead/unconnected buttons
+ *  > no designer plugin needed
+ *  > no killed dialog boxes after editing uis
+ *  > auto connecting the close button to the Dialogs accept / Widgets close (important for close requests on dialogs before closing)
+ *  > solid connections only (safer & faster than connections by char*) [also con]
+ *
+ * Con:
+ *  > no possibility to see which Actions are available for a specific dialog
+ *  > solid connections only (more complicated) [also pro]
+ *
+ * To make Actions visible & usable, use 'connectButton' with the coherant Action (DialogButton).
+ * 'connectButton' works similar to Qt's Connect mechanism, with the main difference that there is neither a sender nor a signal to specify.
+ *
+ * Example:  connectButton(DialogButton::Ok, this, &ThisDialog::accept);
+ *
+ *
+ * >>You have overloaded slots?<<
+ * For example you have:  slotSomethingChanged(int) and slotSomethingChanged(QString)
+ * For the 'int'-version the result should look like: connect(DialogButton::Ok, this, static_cast<void (ThisDialog::*)(int)>(&ThisDialog::slotSOmethingChanged));
+ * Unfortunately this is the Qt version to solve this problem..

+    @see SituationMap::Map, SituationMap::DropEventManager
+
+    The LtsDropHandler class is an interface class to handle drop event for one type of mime data. It is used from DropEventManager to process drop events.
+    The DropEventManager will call the doDrop function to process events. The doDrop fuction has to be implemented in derived class.
+
+    Following example shows how to implement a drop handler.
