Expansion of Narrow Panes to Avoid Wrong Placement at Run Time

When there are two or more narrow root-level panes with a combined fixed width that is less than the available space into which they are rendered, at runtime such panes may be rendered next to each other instead of on top of each other.

To avoid improper pane placement in this case, you can do one of the following:

  • Increase the width of these panes so that there is not enough room left for them to be rendered side by side
  • Set the overflow attribute for the panes to expand, so that the panes expand and fill the available space.
