QDir.setNameFilter how to show only files with specific extensions?

c++, filter, qdir, qt

Solution

For starters, `setNameFilters` does not return `QStringList`, it returns nothing. Your code should look like this:

QDir export_folder("C:\\path");
export_folder.setNameFilters(QStringList()<<"*.exe");
QStringList fileList = export_folder.entryList();

Filtering works as expected (not returning files ending with "exe2") in Linux with Qt 5.0.1.

Problem

setNameFilters isn't working as I would expect, so if anyone can explain if I'm using it incorrectly, or if maybe this is a bug in Qt: Here is my code sample: ``` QDir export_folder("C:\path"); QStringList fileList = export_folder.setNameFilters(QStringList()<<"*.exe"); ``` after processing fileList contains the String "test.exe1" I would expect fileList to only include files with extension .exe NOT .exe*. If I wanted file extensions longer than .exe I would expect to put in `"*.exe*"` as my filter. Can someone help clarify, or do I manually have to process my fileList after the fact?
