I am attempting to browse data in a hidden directory, but the QGIS Browser tree view doesn't show in hidden folders? I know, I know...it's hidden. But is there a command-line switch to override this behavior? The folder in question is APPDATA, so I don't want to make it visible.
The simple answer is: No. Not currently. The browser model doesn't use the
QDir.Hidden flags to show hidden files.
Can it be added to show them? Yep. Open a ticket on hub.qgis.org, assign it to me, and we can go from there.
