hello all ..


I'm working with a java desktop application as a project demanded from my super visor in the university, actually i faced a problem, i really couldn't deal with it


my project contains many Panels, one of them will be considered as a fixed one

i mean in the right space of my frame [ the change of panels (depends on my program) will be happened ] , but the left panel will be fixed when the panels in the right space changing..


see this picture may explain more :

my question is :

can you tell me please how can i make the ( fixed panel ) as auto hide panel ?
i mean how can i make it hidden when the mouse come to its area then it will show up ?


sorry if I'm bothering in somehow .. and i really wish to have an answer
