MUI install section selection problems with mutual exclusive code
This is my first time using NSIS to put together an installer so all due apologies if I'm missing something obvious.
I'm creating an installer to replace a large number of legacy installers and need to represent the various dependencies and incompatibilities in the section selection page of the installer. To this end I've been using a slightly tweaked version of the mutual exclusion code I found on the wiki http://nsis.sourceforge.net/Mutually...sive_Sections. (http://nsis.sourceforge.net/Mutually_Exclusive_Sections)
My problem arises as one of the mutual exclusive pairs lies within a selection tree the root of which has some required installation code (which I represented as a hidden section). An unintended result of this is that it becomes impossible to deselect the root.
Checkboxes change, when clicked, from partially selected to fully selected and from fully selected to unselected. This poses a problem because a selection tree with mutually exclusive sections will never be fully selected and a section group with a hidden section will never become unselected by deselection of its children sections. Thus it gets stuck on partially selected.
Intuitively, I'd expect some way to retrieve which section was clicked like with the onmouseover function, perhaps with an onClick function or something similar which I could use to manually set the response to a click i.e. partial->unselected. I can't seem to find anything helpful, however, that doesn't require making a custom installer page, which I'd rather not do if it is avoidable.
Thanks in advance for any help or advice you can offer.
