Viewer events

[relapse]

Hi!

I'm working with WPF and I try to react to the events fired by viewer. Particularly I need to refresh a TextBox that shows a zooming value after a mouse click with ZoomIn tool (loupe mouse pointer). It doesn't work! Why? If I set a break point in the code, I see that the event handler isn't executed. Here is my XAML definition of the viewer:

Code: Select all

        <WindowsFormsHost Grid.Row="2" PreviewKeyDown="WindowsFormsHost_PreviewKeyDown" MouseLeftButtonDown="WindowsFormsHost_MouseLeftButtonDown">
            <AxPDFXCviewAxLib:AxCoPDFXCview x:Name="pdfViewer">
            </AxPDFXCviewAxLib:AxCoPDFXCview>
        </WindowsFormsHost>

Hello relapse,

Our Viewer AX will not automatically return notification to your main control for any mouse/keyboard input inside the Viewer - so please check section
2.2.2.10.8 Mouse
of the Viewer manual which will let you know how to get information about mouse events in it.

Best,
Stefan

Thanks, I'll read it.

I've found the functionality you offer to capture the viewer events very comfortable and simple e.g.:

Code: Select all

        pdfViewer.SetProperty("Notifications.Mouse.Filter", "All", 0);


        private void PdfViewerEvents(object sender, _IPDFXCviewEvents_OnEventEvent e) {
            // .................
            object dataOut;
            pdfViewer.GetProperty("Notifications.Mouse.msg", out dataOut, 0);
            if ((int)dataOut == 0x202) //WM_LBUTTONDOWN
            {
                object dataOut1;                    
                pdfViewer.GetProperty("Tools.Active", out dataOut1, 0);
                if ((int)dataOut1 == 32610 || (int)dataOut1 == 32611)
                    RefreshZoomValue();
            }
        }

Thanks for your advice. You can mark this thread as solved.
