dalefugier / samplecschromium Goto Github PK

This is never hit: https://github.com/dalefugier/SampleCsChromium/blob/master/SampleCsChromiumPanelControl.cs#L57

To fix it, run Cef.Shutdown() when Rhino shuts down:

RhinoApp.Closing += OnClosing;
...
private void OnClosing(object sender, EventArgs e)
{
   browser.Dispose();
   Cef.Shutdown();
   SampleCsChromiumPlugIn.Instance.UserControl = null;
}

If this project is run as Debug, using Rhino.exe as the application, the Chromium panel works fine and the webpage shows up. If one runs Rhino normally, the webpage never appears.

There is an issue related to HighDPI settings in the Rhino 5 app.manifest when updating CEF to recent versions. Updating to recent CEF versions (>47.0.4) causes the UserControl to render 1/4 of the size on screen. If dpiaware is set to true in the manifest, it renders correctly, but all of the rest of Rhino does not. If this same code is run in Rhino 6, everything works fine with newer versions of CEF.

I'm adding this as a note. To use on Rhino 5 sr12, use CEF 47.0.x. For Rhino 6, more recent versions of CEF can be used.
