[Closed] Rollout autoLayoutOnResize

I have a father Rollout，four child Rollout，
when I creatdiaglog father rollout and set property “autoLayoutOnResize:true style:#(#style_titlebar, #style_border, #style_sysmenu,#style_resizing)”。
father rollout can resizing，but autoLayoutOnResize:true dont work。
I hope child rollout can autolayout。follow father rollout width。
I don’t know if my statement is clear。
Am I using it wrong？or I should do sth？
