SW_deleteExpressions
A library function which allows users to delete the expressions that reference a given
track name and elements from the left-hand side whose names match a regular expression
pattern.
package require SW
SW_deleteExpressions elementNamePattern trackName [sceneID]
- elementNamePattern
- A regular expression pattern which specified the element(s) whose expressions are to be
deleted.
- trackName
- Specifies the track name (such as etrnx or roty) to search for. Pass NULL to
delete all expressions on the elements specified by the elementNamePattern parameter
- [sceneID]
- Specifies the scene to use. This is an optional parameter, if it is omitted the current
scene is used.
Examples
- Delete the rotx expression on all elements in the current scene whose names
begin with sph.
- SW_deleteExpressions sph.* rotx
- Delete all expressions on elements whole names end with left.
- SW_deleteExpressions .*left NULL
Note that this routine uses Tcl regular expressions, so .* matches anything. In this
respect SW routines differ from SWC routines which use a
file like syntax, where * matches anything.
