Listing files by filter on Macbook

All,

Running the following file in Qt Creator on a Macbook Pro 19.6.2.

#include <QTextStream>
#include <QDir>

int main()
{
QTextStream out(stdout);
QDir dir;

QStringList filters;
filters << "*.cpp" << "*.o";

dir.setNameFilters(filters);

QFileInfoList list = dir.entryInfoList();

for (int i=0; i<list.size(); ++i) {
QFileInfo fileInfo = list.at(i);
out << QString("%1").arg(fileInfo.fileName());
out << endl;
}
}


The directory contains some .cpp and .o files,

david-arnolds-macbook-pro-2:Filters darnold$ pwd
/Users/darnold/Documents/temp/myQt/zetcode/Filters

david-arnolds-macbook-pro-2:Filters darnold$ ls -ll
total 456
drwxr-xr-x 3 darnold staff 102 Mar 29 16:52 Filters.app
-rw-r--r-- 1 darnold staff 23 Mar 29 16:44 Filters.pro

-rw-r--r-- 1 darnold staff 404 Mar 29 17:21 filters.cpp
-rw-r--r-- 1 darnold staff 204600 Mar 29 17:22 filters.o

However, when I run Fileters.app from Qt Creator, here is the output:

Starting /Users/darnold/Documents/temp/myQt/zetcode/Filters/Filters.app/Contents/MacOS/Filters...
/Users/darnold/Documents/temp/myQt/zetcode/Filters/Filters.app/Contents/MacOS/Filters exited with code 0

Now (remember I'm on a Mac) if I "Show Package Contents" for Fileters.app, and drop the files filters.cpp and filters.o in /Users/darnold/Documents/temp/myQt/zetcode/Filters/Filters.app/Contents/MacOS/Filters, then "Run" the file again from QtCreator, I get:

/Users/darnold/Documents/temp/myQt/zetcode/Filters/Filters.app/Contents/MacOS/Filters...
filters.cpp
filters.o
/Users/darnold/Documents/temp/myQt/zetcode/Filters/Filters.app/Contents/MacOS/Filters exited with code 0

Should I be constructing my code differently if I want to view the contents of the directory /Users/darnold/Documents/temp/myQt/zetcode/Filters/?

Your code works fine on my Linux box but my executable is in the same directory as the source and build files. Don't know why you have your executable in a separate directory but that looks like the problem. From the Qt docs:

Quote:

---

QDir::QDir ( const QString & path = QString() )
Constructs a QDir pointing to the given directory path. If path is empty the program's working directory, ("."), is used.

---

So you get a listing of "/Users/darnold/Documents/temp/myQt/zetcode/Filters/Filters.app/Contents/MacOS/Filters". If you want a listing of the directory that contains your source code you need to use this:

Code:

---

QDir dir("/Users/darnold/Documents/temp/myQt/zetcode/Filters");

---

That might be the problem you describe in your "Input a text file" post, too. The executable is going to look for the text file in the directory where it resides.

HTH

Well done! That worked perfectly.

Thanks.

D.
