Description
-----------

Hi,
The Gambas interfaces, including ide, do not show the icons according to the current desktop theme.
For example I use Xubuntu with the numix icons and the result is not as expected.
I trying to use the  but the the program l
I am trying to use ToolBar control from gb.mdi instead of a manualy method that I made but the result is bad, the appearance of the icons is "archaic".
Numix is an SVG icon theme maybe there is a problem with that I don't know.
I leave attached screenshots for clarity one is taken from the Gambas IDE other one from a program I made, in this is posible see the icons numix (manual method).
Thanks.
Martín
