Hi Guys,

I had defined a customized layout with a module. When the module was activated, the layout work. However, after I switch to other module and then get back, the customized layout doesn’t work. So how to set the customized layout whenever I switch to this module. I think there should be a function to realize it but I have no idea about that. Any suggestion?  
Thanks

Wenpeng

If you mean that you have [registered a custom view layout](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#customize-view-layout) then you should register it in the application startup completed signal handler and not re-register it again if you enter the module.
