option-popup - option menu |

|

=head1 DESCRIPTION |
| 8 |
|
| 9 |
Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at |
| 10 |
runtime. |
| 11 |
|
| 12 |
Other extensions can extend this popup menu by pushing a code reference |
| 13 |
onto C<< @{ $term->{option_popup_hook} } >>, which gets called whenever |
| 14 |
the popup is being displayed. |
| 15 |
|
| 16 |
Its sole argument is the popup menu, which can be modified. It should |
| 17 |
either return nothing or a string, the initial boolean value and a code |
| 18 |
reference. The string will be used as button text and the code reference |
| 19 |
will be called when the toggle changes, with the new boolean value as |
| 20 |
first argument. |
| 21 |
|
| 22 |
The following will add an entry C<myoption> that changes |
| 23 |
C<< $self->{myoption} >>: |
| 24 |
|
| 25 |
push @{ $self->{term}{option_popup_hook} }, sub { |
| 26 |
("my option" => $myoption, sub { $self->{myoption} = $_[0] }) |
| 27 |
}; |
