Class Wiz_page

The wizard pages to be placed inside the wizard.

To inherit from this class, you must minimally supply the add_contents() method. This method should build the specific GUI elements. The following methods are also designed to be overwritten:

• add_artwork(), this builds the left hand artwork section of the page.
• add_contents(), this builds the right hand section of the page.
• on_display(), this is executed when the page is displayed.
• on_display_post(), this is executed when the page is displayed, directly after the on_display method.
• on_execute(), this is executed when the wizard is terminated or the apply button is hit.
• on_next(), this is executed when moving to the next wizard page.

The following methods can be used by add_contents() to create standard GUI elements:

• chooser()
• combo_box()
• file_selection()
• free_file_format()
• input_field()
• text()

These are described in full detail in their docstrings.
