Listen and get 'e.annots.inserted' event in own plugin

[KarlTH]

Dear Tracker-Support,

I am currently developing an own PDF-XChange Editor-plugin for digital signatures from DocuSign (PDFXEditControl.Inst.AddPlugin(myDocuSignPlugin) and need for it to listen and get an annot. I
made this work, if embedd the PDFXEditControl control with this code:

Code: Select all

 private int _idEventAnnotInserted;

    private void frmMain_Load(object sender, EventArgs e)
    {
        PDFXEditControl.VisibleCmdPanes = PXV_VisibleCmdPanes.PXV_VisibleCmdPanes_All;
        PDFXEditControl.OpenDocFromPath(@"C:\Temp\Vorlage_0383_03.pdf");

        // Get event and save event-id for listening
        _idEventAnnotInserted = PDFXEditControl.Inst.Str2ID("e.annots.inserted");
        PDFXEditControl.EnableEventListening2(_idEventAnnotInserted, true);
    }
    
    private void PDFXEditControl_OnEvent(object sender, _IPXV_ControlEvents_OnEventEvent e)
{
    if (e.nEventID == _idEventAnnotInserted)
    {
        // Listen for new added annot with event-id
        PDFXEdit.IPXV_AnnotsEvent annotsEvent = (IPXV_AnnotsEvent)e.pEvent;
        if (!annotsEvent == null)
        {
            // Get annot from event
            IPXC_Annotation annot = annotsEvent.Items(annotsEvent.Items.Count - 1);
            Debug.WriteLine(annot.Rect.left);
            Debug.WriteLine(annot.Rect.top);

            Debug.WriteLine("New annot with name '" + annot.Name + "' inserted!");
        }
    }
}

But I can't make the same work in my plugin and it drives me crazy.
I tried this but without success:

Code: Select all

public void Setup(PXV_Inst pInstance)
{
    IUIX_Inst uixInstance = pInstance.GetExtension("UIX");
   // Create custom event for listening
    uixInstance.CurrentThreadCtx.RegisterEventMonitor(new CustomEventMonitor(pInstance));
}

public class CustomEventMonitor : PDFXEdit.IUIX_EventMonitor
{
    public void OnEventMonitor(IUIX_Obj pTarget, IUIX_Event pEvent)
    {
        Debug.WriteLine(_uixInstance.ID2Str(pTarget.ID));
       // Get mouse click event instead of AnnotEvent
        if (pEvent.Code == System.Convert.ToUInt32(UIX_EventCodes.e_MouseCaptureLost))
        {
            IPXV_PagesLayoutManager activePageLayout = _pxvInstance.ActiveDocView.PagesView.Layout;
            PDFXEdit.IPXC_Page pdfPage = _pxvInstance.ActiveDoc.CoreDoc.Pages(activePageLayout.CurrentPage);
            uint nAnnotCount = pdfPage.GetAnnotsCount();

            if (nAnnotCount != 0)
            {
                for (uint i = 0; i <= nAnnotCount - 1; i++)
                {
                    PDFXEdit.IPXC_Annotation annot = pdfPage.GetAnnot(i);
                    PXC_Rect myRect = annot.Rect;
                }
            }
        }
    }
}

My main problem ist that I don't know how to get the annotsEvent in a custom EventMonitor of a plugin and therefore I used the mouse click event in my plugin:

Code: Select all

        if (pEvent.Code == System.Convert.ToUInt32(UIX_EventCodes.e_MouseCaptureLost))        

To get the annotsEvent in custom EventMonitor doesn't work as expected and so I hope you can help me!
(Easiest would be that I can listen to OnEvent from the PDFXEditControl in my plugin but I am afraid this would work)

Hello Karl,

What you need, is to create an IEventHandler derived class and implement all of the needed methods. The OnEvent method will catch all of the registered events.
In the FinalizeRegistering method of your plugin, you will have to create that IEventHandler derived class and do something this with the needed events:

Code: Select all

m_pListener = new AppEventListener(this);

	if (m_pListener != nullptr)
	{
		m_pListener->AddRef();
		CComPtr<PXV::IEventServer> es;
		m_pInst->get_EventServer(&es);
		es->RegisterNativeEventHandler(id_e_customizeCmdLayout, m_pListener, 0);
		es->RegisterNativeEventHandler(id_e_beforeShowContextMenu, m_pListener, 0);
		es->RegisterNativeEventHandler(id_e_app_settingsChanged, m_pListener, 0);
		es->RegisterNativeEventHandler(id_e_docSelection_changed, m_pListener, 0);
	}

Then in the IEventHandler derived class, you should catch the events like this:

Code: Select all

STDMETHODIMP AppEventListener::OnEvent(LONG nEventID, PXV::IEvent* pEvent, IUnknown* pFrom)
{
	if (!pEvent || !pFrom)
		return 0;

	if (nEventID == id_e_customizeCmdLayout)
	{
	
	}

Note that if you have string IDs you will have to convert them to numeric IDs.

Hi Alex,

I wouldn't have found this on my own without you help! You are my hero!
I have tested it with AppEventListener and it works perfect! Great!

THANK YOU SO MUCH!

One question to AppEventLister parameter, just for understanding:

Code: Select all

m_pListener = new AppEventListener(this);

(this) as parameter in this code line represents the instance to PXV_Plugin or PXV_Inst?
AppEventListener works also without (this) as parameter. Just for my understanding!


THANK YOU

Hello Karl,

In my case I gave it the IPXV_Plugin implementation so that the listener had access to all of the needed data on my side.
