WebKitPolicyDecisionType

This type of policy decision is requested when WebKit is about to navigate to a new page in either the main frame or a subframe. Acceptable policy decisions are either webkit_policy_decision_use() or webkit_policy_decision_ignore(). This type of policy decision is always a #WebKitNavigationPolicyDecision.

This type of policy decision is requested when WebKit is about to create a new window. Acceptable policy decisions are either webkit_policy_decision_use() or webkit_policy_decision_ignore(). This type of policy decision is always a #WebKitNavigationPolicyDecision. These decisions are useful for implementing special actions for new windows, such as forcing the new window to open in a tab when a keyboard modifier is active or handling a special target attribute on <a> elements.

This type of decision is used when WebKit has received a response for a network resource and is about to start the load. Note that these resources include all subresources of a page such as images and stylesheets as well as main documents. Appropriate policy responses to this decision are webkit_policy_decision_use(), webkit_policy_decision_ignore(), or webkit_policy_decision_download(). This type of policy decision is always a #WebKitResponsePolicyDecision. This decision is useful for forcing some types of resources to be downloaded rather than rendered in the WebView or to block the transfer of resources entirely.
