+* @brief The LtsGridLayout class provides a LayoutItem for the Lts Layout System and is the equivalent to the QGridLayout.
+* An LtsGridLayout can be added to a Widget as any other LayoutItem
+* A LtsGridLayout got two modes:
+* The first one is the normal operation Mode with a fixed ColumnSize
+* every time a widget is added wit add_widget (not addWidget!)
+* it will use the next column at the current used row
+* when maxColum is reached in the current row
+* the Widget will be added to a new row
+*
+* The Second Mode is enabeled with AutoSize
+* There the MaxColumnSize will be calculated
+* when a rezize event accure
