How can I prevent QFileInfo class from prepending C:/ on Windows?
Example:
I would like to store this path on QFileInfo -> /media/my_folder/my_file
On Windows, the absoluteFilePath() function returns C:/media/my_folder/my_file
How can I solve this issue?

I have few directorates and one file *.txt under one Directory A, Directory path is in QString
say c:/A/1/2/3/4
c:B/C/A/1/2/3/4/5/6
In my code I have only the full path, now I want to get the directory until A(name of A can change anytime) based on the file *.txt
inshort:- I want to parse all directory and get the directory until the place where *.txt present from right to left
Are you trying to get the string of the file path to A? Ex. If the file path was:
C:/Users/Admin/Desktop/file.txt
you want to get:
C:/Users
If so, all you have to do is find the second index location of "/". You could do something like this:
QString filePath = "C:/Users/Admin/Desktop/file.txt";
int index = filePath.indexOf("/");
index = filePath.indexOf("/",index+1);
QString shortenedPath = filePath.mid(0,index);
This should give you:
C:/Users/
If that isn't what you meant, then sorry for the long response.
The project root directory of a file located in PROJECT_ROOT/lib/code.jl can be accessed with this code:
root = dirname(dirname(#__FILE__))
Using dirname() twice seems pretty ugly. Is there a better way to do this? With Ruby, I would use this code:
root = File.expand_path('../', File.dirname(__FILE__))
Thanks for making me find out about:
"/"*relpath((#__FILE__)*"/../..","/")
According to ?relpath, it gives a path from the location of the second argument in the file-system, to the first argument. Is this better than the double dirname solution?
A variant of the same niceness is:
normpath(joinpath(#__FILE__,"..",".."))
Closest to Ruby equivalent might be:
realpath(dirname(#__FILE__)*"/..")
I like to use
module Foo
const PROJECT_ROOT = pkgdir(Foo)
end # module
where the definition of PROJECT_ROOT can also be replaced by
const PROJECT_ROOT = dirname(dirname(pathof(Foo)))
Or, you could use
const PROJECT_ROOT = pkdir(#__MODULE__)
I just use
const PROJECT_ROOT = #__DIR__
from inside my _init.jl file, which resides in the project root directory (next to the src directory) and gives you a canonical path.
I get my _init.jl files automatically executed when opening a Julia session from inside that directories by having
isfile("_init.jl") && include(joinpath(pwd(), "_init.jl"))
in my ~/.julia/config/startup.jl file. If you started Julia elsewhere, you have to include("_init.jl") it (or respective relative path) manually.
I'm trying to read and edit a Desktop Entry .desktop file using Qt QSettings. The problem is that these files contain keys with multiple values separated by semicolon ;. I tried reading these as QStringList but no luck. I only get the first value. For example:
Keywords=disc;cdrom;dvd;burn;audio;video;
Categories=GTK;GNOME;AudioVideo;Audio;Video;DiscBurning;
MimeType=application/x-cd-image;application/x-cdrdao-toc;application/x-cue;application/x-toc;audio/x-scpls;audio/x-ms-asx;audio/x-mp3-playlist;audio/x-mpegurl;application/x-brasero;x-content/audio-cdda;x-content/video-dvd;x-content/video-vcd;x-content/video-svcd;x-content/image-picturecd;
Getting the values with:
settings.value("Desktop Entry/MimeType").toStringList();
settings.value("Desktop Entry/MimeType").toString();
returns only the first value (in my example: disc, GTK or application/x-cd-image).
How to I return the full value from those keys? And how do I write it back using QSettings?
Update (first attempt was completely useless)
Variant 1
QMap<QString, QString> settings;
QFile inFile("<input filename.ini>");
if(inFile.open(QIODevice::ReadOnly))
{
QTextStream in(&inFile);
while (!in.atEnd())
{
QString line = in.readLine();
QStringList linelist = line.split("=");
settings[linelist[0]] = linelist[1];
}
}
Variant 2
use QSettings::registerFormat().
This is probably the only "clean" way to do it with QSettings. The advantage is that you can register it with the .desktop extension. You'll have to write a pair of ReadFunc() and WriteFunc() functions.
I think you can't do it. QSettings has certain interpretation of .ini file format, which is very close to Windows interpretation, and is not meant for generic parsing. Semicolon starts a comment, and apparently QSettings allows comment after value until end of line, and AFAIK there's no way around it.
You need to find a different library to handle .desktop files, or implement one yourself.
I'm building a simple file browser using QT, and I can't seem to get the setRootPath() of my model to be set to a file, rather than just a directory.
Ex:
setRootPath("/Users/Foo/Bar") works, but
setRootPath("/Users/Foo/Bar/readme.txt") simply sets the root path to "."
Not sure what I'm missing. Everything else within my application works fine.
You can do this:
QFileInfo m_FileInfo = QString("C:/Users/Foo/Bar/readme.txt");
setRootPath(m_FileInfo.absolutePath());
What we're doing is using QFileInfo to get the absolutePath() of the file. So it'll set the root path to C:/Users/Foo/Bar.
QString fe = "C:\\Program Files\\Autodesk\\Maya2008\\bin\\imconvert.exe ";
This line gives a problem because of space between Program and Files. How is it possible to decode it so that it is treated as one complete string
Brgds,

You can use a QFileInfo object to store it. This object accepts all path even if they have spaces. In addition you have some functions to do all checks you need before using it.
Use QUrl::toPercentEncoding static method
In windows you would do:
QString fe = "\"C:\\Program Files\\Autodesk\\Maya2008\\bin\\imconvert.exe\"";
