NAME

Tk::Wizard::Tasks - Tk::Wizard pages to perform sequential tasks

SYNOPSIS

Currently automatically loaded by Tk::Wizard, though this behaviour is deprecated and is expected to change in 2008.

DESCRIPTION

Adds a number of methods to Tk::Wizard, to allow the end-user to access the filesystem.

METHODS

addTaskListPage

Adds a page to the Wizard that will perform a series of tasks, keeping the user informed by ticking-off a list as each task is accomplished.

Whilst the task list is being executed, both the Back and Next buttons are disabled.

Parameters are as for "blank_frame", plus:

-tasks

The tasks to perform, supplied as a reference to an array, where each entry is a pair (i.e. a two-member list), the first of which is a text string to display, the second a reference to code to execute.

-delay

The length of the delay, in milliseconds, after the page has been displayed and before execution the task list is begun. Default is 1000 milliseconds (1 second). See Tk::after.

-continue

Display the next Wizard page once the job is done: invokes the callback of the Next button at the end of the task.

-todo_photo

-doing_photo

-ok_photo

-error_photo

-na_photo

Optional: all Tk::Photo objects, displayed as appropriate. -na_photo is displayed if the task code reference returns an undef value, otherwise: -ok_photo is displayed if the task code reference returns a true value, otherwise: -error_photo is displayed. These have defaults taken from Tk::Wizard::Image.

-label_frame_title

The label above the Tk::LabFrame object which contains the task list. Default label is the boring Performing Tasks:.

-frame_args

Optional: the arguments to pass in the creation of the Frame object used to contain the list.

-frame_pack

Optional: array-refernce to pass to the pack method of the Frame containing the list.

TASK LIST EXAMPLE

  $wizard->addTaskListPage(
    -title => "Toy example",
    -tasks => [
      "Wait five seconds" => sub { sleep 5; 1; },
      "Wait ten seconds!" => sub { sleep 10; 1; },
      ],
    );
