Enable a subset of plugins

[callum]

Is is possible to enable/disable a subset of the built in Chrome plugins?

For example, I want the user to decide whether to allow Flash to run or not but I would always like the Chrome PDF one to be available.

At the moment they are all turned off - I didn't realize PDF rendering was via a plugin - took me much longer than it should have to figure it out why navigating to a PDF just did nothing at all

Newer CEF versions have CefRequestContextHandler::OnBeforePluginLoad.

Got it.

I implemented that method, set CefBrowserSettings::plugins to false in my setup code and in my overridden OnBeforePluginLoad(..) method, for mime_types of application.pdf, I set *plugin_policy = PLUGIN_POLICY_ALLOW; and return true to indicate I am changing the policy. The PDF does not render though. It does if I set CefBrowserSettings::plugins to true.

What am I doing wrong?

Don't set CefBrowserSettings::plugins to false.

Great - got it working.

The piece I was missing to test Flash on/off as well as PDF on was adding the command line "enable-system-flash" in OnBeforeCommandLineProcessing.

Works as I want now - thanks Marshall.
