I've been experimenting with embedding a webview
(https://github.com/webview/webview) in an fltk application.
This works by just passing an fl_xid of an Fl_Window to the
webview_create function which accepts an opaque pointer to either a
HWND, NSWindow or GtkWindow depending on the platform.
- On Windows, things work fine.
- On MacOS, any manipulation of the embedded window throws an objc
exception (doesn't crash) of unrecognized selector
"did_view_resolution_change" to WKWebView.
"did_view_resolution_change" is a method of FLView which inherits NSView
(in fl_cocoa.mm). I'm not entirely sure why it's being automatically
triggered here or if there's a way to override it or "swizzle" it (I'm
not familiar with Objective-C).
I can't say anything to that part since I don't know the internals.
- On linux, I'm getting the idea that trying to construct GtkWindow from
an Fl_Window is quite complex. Apparently it's possible to construct a
GdkWindow from an XID, however getting a GtkWindow from a GdkWindow is
not possible. I'm not sure of any other way to do it. I would appreciate
any insight on the feasibility of doing this.
The only information I can offer is that the XID of the FLTK window is
nothing but the X11 Window (id), i.e. the type 'Window', but you seem to
know that already.
Maybe someone here has experience with your specific question, but
generally I'd say this is the wrong group to ask, you should better ask
in a Gtk related user group/forum.
