+      \param todo The to-do to be printed. It's sub-to-dos are recursively drawn, so drawTodo should only be called on the to-dos of the highest level.
+      \param p QPainter of the printout
+      \param sortField Specifies on which attribute of the todo you want to sort.
+      \param sortDir Specifies if you want to sort ascending or descending.
+      \param connectSubTodos Whether sub-to-dos shall be connected with their parent by a line (tree-like).
+      \param strikeoutCompleted Whether completed to-dos should be printed with strike-out summaries.
+      \param desc Whether to print the whole description of the to-do (the summary is always printed).
+      \param posPriority x-coordinate where the priority is supposed to be printed. If <0, no priority will be printed.
+      \param posSummary x-coordinate where the summary of the to-do is supposed to be printed.
+      \param posDueDt x-coordinate where the due date is supposed to the be printed. If <0, no due date will be printed.
+      \param posPercentComplete x-coordinate where the percentage complete is supposed to be printed. If <0, percentage complete will not be printed.
+      \param level Level of the current to-do in the to-do hierarchy (0 means highest level of printed to-dos, 1 are their sub-to-dos, etc.)
+      \param x x-coordinate of the upper left coordinate of the first to-do.
+      \param y y-coordinate of the upper left coordinate of the first to-do.
+      \param width width of the whole to-do list.
+      \param pageHeight Total height allowed for the to-do list on a page. If an to-do would be below that line, a new page is started.
+      \param todoList Contains a list of sub-todos for the specified @p todo .
+      \param r Internal (used when printing sub-to-dos to give information about its parent)
