I am experimenting with the WebView2 Composition Controller for the goal of allowing the user to drag and drop files from their desktop into specific areas of my GUI. In order for the Composition Controller to work, it needs to have it’s “root visual” set which is part of the composition visual tree
See WebView2 Win32 C++ ICoreWebView2CompositionController | Microsoft Learn
Since we now use the D2D renderer which participates in the modern windows visual tree (see JUCE/modules/juce_gui_basics/native/juce_Direct2DHwndContext_windows.cpp at 501c07674e1ad693085a7e7c398f205c2677f5da · juce-framework/JUCE · GitHub ) it feels like it should be possible to create and insert another visual here that I can bind to the WebView2 Composition Controller.
Will this be made available in the future as an API, or is there a recommended path for forking my own way to get this capability?
