[NTLUG:Discuss] How to take off the window's decoration??

[xiao li]

Hi guys,
I find the problem!
If I just set the hints.decorations = 0; then I can get rid of the 
decoration. But if I use hints.decorations = MWM_DCOR_ALL | MWM_DECOR_BORDER 
| MWM_DECOR_TITLE...; then it won't work on linux.
Thanks for you guys.
