parse_string

Tries to parse the given string into a trigger.

On success, the parsed trigger is returned. When parsing failed, null is returned.

The accepted strings are:

• `never`, for `GtkNeverTrigger`
• a string parsed by accelerator_parse, for a `GtkKeyvalTrigger`, e.g. `< Control>C`
• underscore, followed by a single character, for `GtkMnemonicTrigger`, e.g. `_l`
• two valid trigger strings, separated by a `|` character, for a `GtkAlternativeTrigger`: `<Control>q|<Control>w`

Note that you will have to escape the `<` and `>` characters when specifying triggers in XML files, such as GtkBuilder ui files. Use `&lt;` instead of `<` and `&gt;` instead of `>`.

Parameters:

string

the string to parse

Returns:

a new `GtkShortcutTrigger`
