+ Timeline: find a workaround to cause the Box to reflow the rulerCanvas
+
+
+
+ seemingly, the Box with PACK_SHRINK allocates a zero height to the rulerCanvas initally,
+
+ which is correct at that point, since the widgets are not yet realised.
+
+ However, when we later set_size() on the rulerCanvas, the enclosing Box should reflow.
+
+ It does indeed if the child widget is a button or something similar, however,
+
+ somehow this reflowing does not work when we set_size on the canvas.
+
+
+
+ A workaround is to place a new set_size_request().
+
+
+
+ TODO: do this more precisely, and only on the rulerCanvas. To the contrary,
+
+ the mainCanvas is placed into a scolling-pane and thus does not need a size-Request.
+
+ Moreover, the latter automatically communicates with the hadjustment() / vadjustment() of
+
+ the enclosing scrollbars.

+ Timeline: implement function to set the drawing canvas size
+
+
+
+ as can be verified with the debugger, it sets the correct sizes now.
+
+ And it is called only once (unless the content size actually changes).
+
+
+
+ TODO: however, the visible display of the GTK widgets is not adjusted
+ per DUMP-Print verifiziert: Maximalwert der Scrollbar (=hadj) ist identisch mit get_allocated_width
