Is importAnXFDF and flattenPages synchronized

[RudolfErnst]

In the past (Nov 07, 2008) i opened a new topic "Is OpenDocument synchronized". I wanted to know whether OpenDocument is synchronized In other words: is the document completely displayed on the screen when the method returns S_OK or does it just trigger the rendering and returns immediately. If it's asynchron is there another method to determine if rendering is complete (isLoaded(), isFinished()??). I use Eclipse RCP and the ActiveX control of PDF-XChange.

Vasyl Yaremyn told me that I have tu use Documents.ContentMonitor and ask for the property Documents[<ID>].ContentReady. This worked perfect. Now I have a similar question: Is importAnXFDF and flattenPages synchronized?. Is there a property I can monitor to get informed that importAnXFDF (and also flattenPages) is ready, that means rendering is finished and PDFXChange is ready for the next command.

kind regards

Hi Rudi,

I've passed this question to Vasyl again - and he should reply here shortly!

Hi Rudi,

Sorry for delay again but we are very busy with new version of viewer..

For your case if you wanted to known when rendering of pages is finished you may use the similar method:

Code: Select all

SetDocumentProperty(docId, "ContentMonitor", "On");
...
foreach (operationsQueue)
{
  call operationsQueue[i]->Run(); // importAnXFDF/flattenPages
  WaitForContentReadyFlagWithMessageLoop();
}
...
bool bContentReady = true;
UpdateContentReadyFlag()
{
    bContentReady = true;
    GetDocumentProperty(docId, "ContentReady", out bContentReady);
}
...
WaitForContentReadyFlagWithMessageLoop()
{
    UpdateContentReadyFlag(); 
    // windows messages pumping with checking the 'ContentReady' flag
    while (!bContentReady)
    {
       if (PeekMessage(msg))
           DispatchMessage(msg);
       else
            Sleep(100);
    }
}
....
youreventhandler OnEvent(type, name)
{
    if ((type == PXCVA_OnPropertyChanged) || (StrStr(name, ".ContentReady") == 0))
    {
        UpdateContentReadyFlag();
    } 
}

I'm afraid but no simple way to detect when control is really idle...
In new version of SDK you will be able to catch exact 'begin/end' events of any action inside control.

Also you may try to use other option - "Performance.SyncRendering"

HTH.
