Hi Fons, Thank you very much for your suggestion. It is a beautiful browser, and it is exactly what I needed. Currently I'm in the process of integrating this browser with the rest of my software. However, I still have one more question - this time about the RootEmbeddedCavas. Namely, a user can click with the right button on any pad and may delete it (by choosing delete from the popup menu). This is fine if he/she deletes a sub-pad. However, when we try do delete the TCanvas, which is it self in the RootEmbeddedCanvas, than the next time we will want to use RootEmbeddedCanvas we will get a segmentation violation. Nothing strange - the pointer is there, but memory already deallocated. My question is: Can we somehow block a TCanvas from being deleted by the user. (perhaps some option ?)
