QtIFW how to check previous installation & read settings on MacOS
-
Hi everyone,
On windows, I use installer.value("HKLM\Software\com\product\installFolder") to read registry to detect if previous installations are already here, and to read some settings such as old version value. It works perfect.
But on MacOS, I don't know how to do the same things. I thought I can create a .plist file like ~/Library/Preferences/com.product.plist, to store previous installation folder and old version number. But, QSettings cannot be used in QtIFW controlscript.js. I have no idea now.
Any suggestions? Thanks very much.
