Add regions to the dashboard.
An array whose keys are the names of the dashboard regions and whose values are the titles that will be displayed in the blocks administration interface. The keys are also used as theme wrapper functions.
Note: this list is generated by pattern matching, so it may include some functions that are not actually implementations of this hook.
function hook_dashboard_regions() {
// Define a new dashboard region. Your module can also then define
// theme_mymodule_dashboard_region() as a theme wrapper function to control
// the region's appearance.
return array(
'mymodule_dashboard_region' => "My module's dashboard region",
);
}
