Moving CEF view from one content window to another (Mac)

[francoismarchal]

Dear all,

I'm using CEF views in an application that allows the user to drag a browser view from one window to another. So I need to detach the NSView created by CEF from the content view of one NSWindow and attach it to another content view. It works well on Windows, I can set the parent to the CEF browser host HWND to the window of my choice.

The problem I have on Mac is that when I try to remove CEF browser host NSView from its parent view, CEF detects that the view is no longer attached to a window and it disposes the browser is closed. When I attach the view on my new window, there is no content.

This appends when I execute

Code: Select all

[myCEFHostView removeFromSuperView];

If I try to avoid to remove the view first from its superview, and add it to the new view directly, it crashes

Code: Select all

[myNewContentView addSubview: myCefHostView]

Any clue ? How does Chromium Mac handles moving one tab from one window to another ?

Thanks for your help!

We perform similar logic in cefclient: https://bitbucket.org/chromiumembedded/ ... _mac.mm-47

Check that you're not releasing references to the NSView before the reparenting process is complete.

Thanks a lot it works now, that was my mistake!
