I have made some buttons in a floating toolbar. These buttons open different locations on my HDD. I would like to be able to close the lister for the button if the lister is already open.
In other words, let's say I click on a button called pictures, a folder called pictures will be opened in the lister. Now the second time I click on the button, I want to close the lister if the pictures folder is already open in the lister.
Does anyone know how this can be achieved?
