CGI::Test::Form::Widget::Button - Abstract representation of a button
# Inherits from CGI::Test::Form::Widget
This class is the abstract representation of a button, i.e. a submit button, an image button, a reset button or a plain button.
Pressing a button is achieved by calling
press() on it, which returns a new page, as a
CGI::Test::Page object, or
undef if pressing had no round-trip effect.
The interface is the same as the one described in CGI::Test::Form::Widget, with the following additions:
True when the button is pressed.
Press the button, setting
is_pressed to true.
If the button is a reset button (
is_reset is true), all widgets are reset to their initial state, and
undef is returned.
If the button is a submit button (
is_submit is true), then a GET/POST request is issued as appropriate and the reply is made available through a
Otherwise, the button pressing is ignored, a warning is issued from the perspective of the caller, via
undef is returned.
There is an additional set of predicates to distinguish between the various buttons:
Returns true for a plain button, i.e. a button that has no submit/reset effects. Usually, those buttons are linked to a script, but
CGI::Test does not support scripting yet.
Returns true for reset buttons.
Returns true for submit buttons, whether they are really shown as buttons or as images. A submit button will cause an HTTP request to be issued in response to its being pressed.
Although documented, those features are more targetted for internal use...
Change the pressed status of the button, to the value of flag. It does not raise any other side effect, like submitting an HTTP request if the button is a submit button.
You should probably use the
press convenience routine instead of calling this feature directly.
