-    profiles, screen resolution, or screen orientation. The component size
-    might also be zero (0,0) if its final size is determined by property
-    bindings.
-
-    To experiment with different component sizes, enter values in the
-    \uicontrol {Override Width} and \uicontrol {Override Height} fields (1) on
-    the canvas toolbar. The changes are displayed on the canvas (2)
-    and in the \uicontrol States view (3), but the property

-
-    \section1 Refreshing the Canvas
-
-    When you open QML files in the Design mode, the items in the file are drawn
-    on the canvas. When you edit the item properties, the QML file and
