Hello to all fpc friends

When I'm using QT for my project, the icon of MenuItems not work.
I try this way to use icons:
1. Open Lazarus IDE and create new project.
2. Drag to it a TMainMenu.
3. Double click on TMainMenu and modify items. create submenu and change Bitmap of them. select a icon for them.
4. Comple & Run project. I don't see any icon in menu

I'm running ArchLinux 64 bits. I'm using lazarus-qt.
Thank you. I'm waiting for your answers.
