When and where does Panels get the title out of a View?

Question

Two part question about Drupal 7, Panels 3, and Views 3.

I have a view that I have added to a content area in a panels page. Right now, the title from the display is being used as the pane title. I need to dynamically set the title of this from a module.

1. When does Panels pull out the display title from the view?

2. Where exactly does it pull it out from?

I cannot seem to override this from any view hook. For example,

function foo_views_pre_view (&$view, &$display_id, &$args)
{
    $view->display[$view->current_display]->display_options["title"] = "Foo";
}

doesn't seem to affect the pane title, though the value does propagate through all of the other view hooks.

I suspect I can create a workaround and use a custom block instead of the view directly, but I would rather not do that in this case.

Thanks.

Answer 1

I was hoping that someone would answer this, so I wouldn't have to answer my own question when I found the solution.

Credit goes to a co-worker (who doesn't really post here) who reminded me that you also need to update the handler:

function foo_views_pre_view (&$view, &$display_id, &$args)
{
  $view->display[$view->current_display]->display_options["title"] =
  $view->display[$view->current_display]->handler->options["title"] = "Foo";
}

When you do this, the title does propagate properly to the pane title.

Answer 2

Drupal grabs the view title from the view itself when the view is rendered.

You can over ride this in the panels settings area, by manually setting it.

Revision:

Have you tried doing this with a preprocess function something like

function MYTHEME_preprocess_panels_pane(&$vars) {
 if ($vars['pane']->type == 'node_title') {
  $vars['template_files'][] = 'panels-pane-node-title';
 }
}
