Help with QFileSystemModel

[squidge]

QFileSystemModel can return zero for rowCount until the node is populated, as it uses a seperate thread for populating the tree. It'll send a signal when the count has changed.

I'm not really sure how to get it to what you want, and it's not really meant for that.

Maybe QDir would be better for you, as that isn't threaded, and you can call entryInfoList to get a list of all files and directories in the directory.

Maybe that's the problem. I've already implemented the feature a few different ways, using QDirModel, QDir, and QDirIterator. The issue is with performance. There are almost 4,000 directories and it takes 3-4 seconds to perform the operation. I was just hoping for a faster solution.

What is the intended last result? As in, what are you going to do with your list of filenames once you have them?

There might be better way.

The intended use is to find all directories below a starting directory that contain a certain string. That list will be presented at various places within the application and the search string may be different.
