HIViews and Quickdraw - Mac Programming

Hi, In order to support brush metal, I am adapting my Carbon Quickdraw framework to support compositing. Everything works fine for standard controls. In order to handle custom content, I have succesfully created a custom HIView, and added it to the content view of the window. The problem I have is when my custom control is called with kEventControlDraw, I cannot get a quickdraw port. I can get a valid CGContext using the following: err = ::GetEventParameter (inEvent,kEventParamCGContextRef,typeCGContextRef, 0,sizeof(gc),0,&gc); But when I call err = ::GetEventParameter (inEvent,kEventParamGrafPort,typeGrafPtr,0,sizeof( port),0,&port); I get a eventParameterNotFoundErr err.

    Default HIViews and Quickdraw

    Hi,

    In order to support brush metal, I am adapting my Carbon Quickdraw framework
    to support compositing.

    Everything works fine for standard controls. In order to handle custom
    content, I have succesfully created a custom HIView, and added it to the
    content view of the window.

    The problem I have is when my custom control is called with
    kEventControlDraw, I cannot get a quickdraw port.

    I can get a valid CGContext using the following:

    err = ::GetEventParameter
    (inEvent,kEventParamCGContextRef,typeCGContextRef, 0,sizeof(gc),0,&gc);

    But when I call

    err = ::GetEventParameter
    (inEvent,kEventParamGrafPort,typeGrafPtr,0,sizeof( port),0,&port);

    I get a eventParameterNotFoundErr err.

    Am I doing something wrong ?
    Is this a known bug ?
    Is there a workaround ?

    I could not find any function to convert a CGContext to a grafport.

    I don't want to use Quartz because the framework needs to run on MacOS 9.

    AHWBA.

    Eric

    Just read the doentation :
    from CarbonEvents.h :

    kEventControlDraw
    Required parameters:
    --> kEventParamDirectObject typeControlRef

    Optional parameters:
    --> kEventParamGrafPort typeGrafPtr
    (draw into the current port if kEventParamGrafPort
    is not present)
