48.4 SmartIDs - special characters
The special characters :, @, & and %
have special meanings in SmartIDs.
":" terminates a component class or UI engine.
A % at the start of a SmartID signals the use of a regular expression (see section 49.3).
The other characters mark the beginning of a sub-item, like a table cell.
If these characters should appear in a SmartID with their literal meaning,
they must be escaped by prefixing them with \.
Example: A dialog title containing an email address is to be used as SmartID.
The @ inside must be escaped like this: #abc\@qftest.com.
A % at the beginning of a SmartID, directly after the #,
can not be escaped.
In this case it is better to place a prefix or the class between # and %.
Now, % can be escaped with a \.
Example: A button has the label %.
As SmartID, you can use #Button:\% or #Label=\%.
A ":" character that is part of a built-in generic class (see chapter 61),
like Panel:TitledPanel, does not need to be escaped.
