I need allow or no docking according the content.
For more detail, I use some DocmentPane with some DocumentContent. I want allow the behaviour floatting for the DocumentContent, but i dont want allow DocumentContent change DocumentPane. DocumentPane can only redock on original DocumentPane.
I dont know how process. I dont find drog event to check and accept the content. My DocumentPane is herited class, else i can overwrite some methodes. But DocumentPane dont have virtual Drog method.
Thank for your helps.
