Is there a modifier that would disable lister (owns it) when showing a dialogue? Which means I will not be bale to click\interact with the lister until the dialogue is closed.
I'm using a simple @confirm: message to confirm action.
Also, is it possible to set dialogue icon?
You should not normally need to disable the parent window. Things like the list of selected files are given to your script as a snapshot which will only be updated if the script asks for it, so you should not have to worry about things being changed in the lister, nor prevent the user from using the lister for other things after launching your script.
Ah, apologies, my answer applied to scripting. My mistake, given you mentioned @confirm which isn't a scripting thing. I was still thinking about scripting from a previous thread.
I think you would need to use scripting to be able to control whether the parent window is disabled when showing a dialog.
