I use cocoa calls to set an webView:decidePolicyForNavigationAction:request:frame:decisionListener:

By this callback, I can decode about what to do with the links some user clicked. But sadly, if there is some iframe inside, I do not get the callback for the links inside of the iframe.

I tried using findFrameNamed: function to get the webFrame of the iframe (seem to work) and then getting the underlying webView to set the decisionListener there, but it does not fire.

Any hints?

PS. I use PureBasic, calling the Cocoa functions manually. So I can only add my PB code, if this is of any help:

Global appDelegate = CocoaMessage(0, CocoaMessage(0, 0, "NSApplication sharedApplication"), "delegate")

Global delegateClass = CocoaMessage(0, appDelegate, "class")



ProcedureC PolicyDecisionMaker(obj, sel, webView, actionInformation, request, frameName, listener)

  ; handle all links like it is _blank target. We do not want something else in regify client.

  Protected URL = CocoaMessage(0, request, "URL")

  Protected URLText.s = PeekS(CocoaMessage(0, CocoaMessage(0, URL, "absoluteString"), "UTF8String"), -1, #PB_UTF8)

  Debug "URL: " + URLText.s

EndProcedure



class_addMethod(delegateClass, 

                sel_registerName("webView:decidePolicyForNavigationAction:request:frame:decisionListener:"), 

                @PolicyDecisionMaker(), 

                "v@:@@@@@")



Procedure.i SetMacWebgadgetTargetSupport(WebgadgetID.i, iFrameName.s = "")

  If iFrameName.s = ""

    CocoaMessage(0, GadgetID(WebgadgetID.i), "setPolicyDelegate:", appDelegate)

    ProcedureReturn #True

  EndIf



  Protected macMainFrame = CocoaMessage(0, GadgetID(WebgadgetID), "mainFrame")

  Protected maciFrameView = CocoaMessage(0, macMainFrame, "findFrameNamed:$", @iFrameName.s); get iframe

  If maciFrameView <> 0

    ; Set appDelegate on the given iFrame

    Protected macWebView = CocoaMessage(0, maciFrameView, "webView") ; get webView object

    CocoaMessage(0, macWebView, "setPolicyDelegate:", appDelegate)

    ProcedureReturn #True

  EndIf

  ProcedureReturn #False



EndProcedure

The above works fine on normal HTML (eg file://somefile.html). But it fails for iFrame with links inside.
