The Rtl_gridwin manages scrollbars for its child window. The child window is assigned to the Rtl_gridwin through the 'widget' property.
Example 7.1. Using Rtl_gridwin
# Note: gridwin is the parent window.
rtl_gridwin .gridwin -window .gridwin.child
# The child window is being instantiated
# after the gridwin:
text .gridwin.child
…
# Notify the gridwin to refresh itself, and
# map the 'child' window on screen.
.gridwin update
The Rtl_gridwin design provides a standardized way for scrollbar management in an application. There is no need to assign: xscrollcommand, yscrollcommand, xscrollstartcommand, yscrollstartcommand, xscrollstopcommand or yscrollstopcommand.
The Rtl_gridwin uses the grid geometry manager to display its children. The assigned window is mapped on screen after calling 'update' .
