+\note The minimal distance searching task can have one or more
+solutions, and also it can have an infinite set of solutions. All
+found solutions are listed in dedicated combobox. When the user
+selects any one of found solutions, presentation is displayed in the
+OCC viewer and fields "Length", "DX", "DY" and "DZ" are filled with
+corresponding values. If there are no solutions found, text "No
+solution found" will be shown instead of solutions list; this could
+mean what the task has an infinite number of solutions.
