GET and POST HTML form and link query string variables
HTML only
The value of these variables is set in HTML forms or in the query string of links
In HTML code or text this XtGem code will be replaced by the value of the GET or POST variable with var_name or the optional default value will be used if the variable is not set
Note: the pipe symbol | must still be used if no default value is set or the code of the variable will be shown if the variable is not set
{_$var_name|default value}
For example the URL of this page uses a query string variable which can be read like this
{_$func|}
The value of the variable func is get_variables
The variables are parsed before Xt functions and widgets so they can be used to supply values to the function or widget
The text of this gradient text widget can be set using the form
