AddTabCallback

Adds a callback that is invoked when a tab is activated or deactivated.

Note: This method applies to individual tabs, not the tab container control that holds the tabs.

Parameters

Name	Type	Description
`objname`	String	The name of the tab.
`callback`	Function	The function to be invoked when the tab is activated or deactivated.
`activated`	Boolean	Whether to invoke the callback when the tab is activated or deactivated.

Return Value

Result	Value
(none)

Example

This example registers a named function to be called when a tab is activated or deactivated:

function customTabCallback()
{
    if ( IsFieldEmpty( "Problem" ) )
    {
         ShowErrorDiv( true, "A problem entry is required" );
    }
    else
    {
         ShowErrorDiv( false );
    }
}
AddTabCallback( "ProblemsSection", customTabCallback, false );

Comments

Callbacks are invoked in the order in which they are added. This callback can be used to perform validation or other data verification. If you want to display a field validation error, call MakeFieldInvalid from this callback so that any required or invalid field errors are automatically processed.
