Radio style instead of MF_CHECKED for menu item?

I noticed some applications ha开发者_如何学Cve a blue circular instead of a checkmark which MF_CHECKED produces. Which style produces this circular one?

Thanks

You normally use the CheckMenuRadioItem function to handle menu radio buttons since it does all the style and checkmark handling for you

Check out the MFT_RADIOCHECK menu type flag...
