Method Details

create

public static PreferencePageSupport create(PreferencePage preferencePage,
 DataBindingContext dbc)

Connect the validation result from the given data binding context to the given preference page. Upon creation, the preference page support will use the context's validation result to determine whether the page is valid. The page's error message will not be set at this time ensuring that the preference page does not show an error right away. Upon any validation result change, PreferencePage.setValid(boolean) will be called reflecting the new validation result, and the preference page's error message will be updated according to the current validation result.

Parameters:

preferencePage - the preference page to show validation errors on

dbc - the binding context to connect

Returns:

an instance of PreferencePageSupport

handleStatusChanged

protected void handleStatusChanged()

Overrides:
