java - How can I make a custom Window without borders that is still resizable -

hi programmers out there! :d

i want create jframe without borders , size buttons. example frame of steam-program pc. searched , found jwindow , setundecorated method jframe.

when use 1 of these options window without borders, can't resize it. there easy way keep feature, "snap-feature"? mean valve managed solve problem somehow :)

this question describes want, there 1 answer , it's not helpful...

check out resizing components. general purpose class allows resize component. provide appropriate cursor mouse around edge of frame.

basic usage frame be:

jframe frame = new jframe("sscce"); frame.setundecorated( true );  componentresizer cr = new componentresizer(); cr.registercomponent(frame); 

of course need make sure frame has blank border around edges mouseevents passed frame , not component added frame.
