How do I change the WM icon for a gwindow() using gWidgets in R?

Question

I would like to change the Window Manager icon (in the top left corner of my gwindow()), using gWidgets in R. I want to add my own picture rather than using the R logo in the corner. I have loaded the picture into R, just by calling gimage("imagename.jpg"). I can manage to open this image up in a window, by calling gimage("imagename.jpg", cont=gwindow(cont=T)), but not as the icon.

I feel like this should be something really simple to do. I have googled how to do it, but can't find an answer. I found that, using RGtk2, you just add the argument icon=imagename when creating the window.

I tried this with gWidgets as well by calling gwindow(icon=gimage("imagename.jpg"), cont=T), however this didn't do anything different than just calling gwindow without the extra argument.

This seems like it should be really simple, but I can't find an answer anywhere. Any help would be greatly appreciated.

Thanks.

There is nothing in gWidgets here to help, but if you load RGtk2, then the setIcon method of the GtkWindow can help you, but you need to get it first:

Try something like:

w <- gwindow()
require(RGtk2)
img <- gdkPixbufNewFromFile("your_icon.png")
getToolkitWidget(w)$setIcon(img$retval)
