Tk Library Source Code

Motivation:
The ScrolledWindow widget has a problem when making it
centered together with automanaged scrollbars: each
time the displayed frame changes its size, the
scrollbars might get gridded for a short time when they
are not needed and consequently ungridded shortly after
that, causing the inner frame to 'jump'.

The following patch addresses this by adding an
-autodelay option. If this is used, the widget will
wait (-autodelay milliseconds) before it calls the
routine the grids/ungrids the scrollbars and will
always use the last values given to it so that multiple
calls to the widget just get 'compressed' to one call,
effectively using the last valid values.

The attached tar contains the diff to the actual head,
the complete new panedw.tcl source and the updated
documentation in case the patch should be accepted.

Effects to existing code:
None. The default is to behave like no -autodelay was
given.

Bugs:
None that I knew of.
