NAME
XmtLayoutDisableLayout(), XmtLayoutEnableLayout() - temporarily disable layout computation for an XmtLayout widget.SYNOPSIS
void XmtLayoutDisableLayout(Widget w)
void XmtLayoutEnableLayout(Widget w)
ARGUMENTS
INPUTS- w
- An XmtLayout widget.
DESCRIPTION
XmtLayoutDisableLayout() stops the XmtLayout widget w from recomputing the arrangement of its children when it normally would. XmtLayoutEnableLayout() restores normal layout computation for w.Use these functions if you are making an number of changes to the children of w (managing, unmanaging, repositioning, resizing) that would cause w to recompute the children's arrangement. By batching all the changes between XmtLayoutDisableLayout() and XmtLayoutEnableLayout() significant unnecessary computation can be avoided.
Calls to these functions are counted and may be nested-layout will not be re-enabled until XmtLayoutEnableLayout() has been called as many times as XmtLayoutDisableLayout().
