In the current code it's done simply with a Gtk2::Arrow
widget child, but with various properties and style settings arranged to make it fill the button, and to avoid the arrow's otherwise hard-coded 15 pixel minimum size.
FUNCTIONS
$ab = App::MathImage::Gtk2::Ex::ArrowButton->new (key=>value,...)
-
Create and return a new ArrowButton object. Optional key/value pairs set initial properties per
Glib::Object->new
.my $ab = App::MathImage::Gtk2::Ex::ArrowButton->new (arrow_type => 'left');
PROPERTIES
arrow-type
(Gtk2::ArrowType
enum, defaultright
)-
The arrow type to show, one of
up
,down
,left
,right
ornone
.none
means nothing is shown. The default is the same asGtk2::Arrow
.
IMPLEMENTATION NOTES
Gtk2::Arrow
always responds to its $arrow->size_request
asking for 15x15 pixels. Most container widgets (including Gtk2::Button
) respect that and the effect is that it can be made bigger if desired, but no smaller than 15 pixels. A $arrow->set_size_request(1,1)
or similar can be used to reduce it if the container's size is going to be determined elsewhere and the arrows shouldn't have a minimum.
