unable to hide combobox or spinbox in toolbar

Hi,

i am unable to hide combobox or spinbox in toolbar
i have added one combox, one spinbox and many actions to my toolbar

I have added above toolbar to my main window

There are multiple items in my scene.

when i selects item in scene i am showing the toolbar associated with that item.

my above said toolbar is shared by two items but the functionality differs a little.

so i want to hide few functionalities in toolbar when i selects a particular item.

i have implemented focusInEvent of item and calling a mathod of toolbar to hide combobox and spinbox.

in that method i am calling setvisible method of both widgets

but these are shown whenever i calls show method of my toolbar

please tell me the reason behind this unexpected behaviour

if you need more info please let me know i will try to explain it in more details.

Thanks & Regards,

Sandip
