Checkboxes with three states
I want to make a kind of instaler/uninstaler/reinstaler for serveral components in one application. All in one. I'm using the modern interface and in order to do it I'd need to know is if possible in the components page to detect/program one action when a component checkbox is checked or unchecked.
It will also be good if this checkboxes could have three states: install, uninstall and reinstall, but I don't know if it is even possible.
Any help will be welcome, thanks in advance.
