The browser needs to know when the parent component has been resized to resize the contents.

The TCEFWindowParent does that overriding the Resize procedure.

You can use a handle from another process to be the browser parent but you will miss several browser functions.

I haven't tried that on a different process but I guess you can try to use a similar method to the one used in TCEFWindowParent.UpdateSize.

Call TChromium.WindowHandle to get the browser handle and then use BeginDeferWindowPos, DeferWindowPos and EndDeferWindowPos.

TCEFWindowParent uses GetWindow(Handle, GW_CHILD) instead of TChromium.WindowHandle. Try both if necessary.
