dot-underscore file on macOS are in playback

[Ting]

Environment:

• OS: macOS 14.3
• qView version: 6.1

Information:

When files are copied over and opened on a flash drive, the "dot-underscore files" are created by macOS. They can be cleaned easily such as dot_clean, but it is kind of annoying to do that each time.

I dig into the code a bit and find the logic around this place it a bit incorrect.

qView/src/qvimagecore.cpp

Lines 273 to 290 in 6c7a99d

     if (fileName.endsWith(extension, Qt::CaseInsensitive)) 
     { 
         matched = true; 
         break; 
     } 
 } 
 QString mimeType; 
 if (!matched || sortMode == 4) 
 { 
     mimeType = mimeDb.mimeTypeForFile(absoluteFilePath, mimeMatchMode).name(); 
     matched |= mimeTypes.contains(mimeType); 
 } 
  
 // ignore macOS ._ metadata files 
 if (fileName.startsWith("._")) 
 { 
     matched = false; 
 } 

Ideally when the dot file are read, they should not be matched; however because the dot files also have JPG extension, the loop breaks early.

Maybe adjust the order of these conditions, or rewrite the logic a bit?

@yo1995 The logic to ignore dot-underscore files was added after the qView 6.1 release, so it's only present in the nightly builds currently. You can try out the build here which should work; it does for me at least.

Yes looks to me like the feature is already implemented. Nice catch.
