Hmm, I think that this is not the expected answer to the OP's question. His problem seems to be to draw his symbol (a png image) at the correct position within a menu, i.e. to get the x/y coordinates of a specific menu item. That said, and looking at the symbol drawing code in fl_symbols.cxx, I assume that this is not going to work as expected. The symbol drawing functions are using coordinate transformations to draw the symbol in the right place, and I also assume that the image drawing functions don't use the transformation matrix that has been set before calling the symbol drawing function. To Yassine: Sorry, I can't help any further, maybe someone else can shed more light on this. I don't have the time to invetigate more, but you should take a look at the drawing chapter in the docs to learn more about which drawing functions use the coordinate transformation matrix and which don't. In the worst case you would need to write your own image drawing function that uses only the drawing functions that honor the transformation matrix. ... or I might be completely wrong with my assumptions ...
