No, because you are not supposed to generate an AppImage with the 
development version of Gambas, i.e. use the daily Gambas PPA.

The IDE only uses the stable PPA.

The AppImage can only use the widget and icon themes provided by the 
Ubuntu packages installed in it. So by default, you have the default 
decided by Ubuntu on the specific Ubuntu version you chose.

With the IDE, you can manually specify additional packages to install 
inside the AppImage, so you should easily be able to add new widget/icon 
themes. But you won't able to modify the configuration files of Qt or 
GTK+ to use theme, you have to do that inside your application with 
'Application.Theme'.
