C++ Qt 49 - QFileSystemModel a simple file explorer example

[@JedEvnull]

Probably one of the best coding tutorials I've seen. No jarring music, clear easy to understand speech. Good job!

[@TheSilverbar]

Hi, Brian - great tutorial (as usual).
Sometime between when you made this video, and the introduction of Qt 5.8, it became necessary to add a step to get this to work. You now have to set the root indexes of the UI items:
QString sPath = "/home";
dirModel = new QFileSystemModel(this);
dirModel->setFilter(QDir::NoDotAndDotDot | QDir::AllDirs);
dirModel->setRootPath(sPath);
ui->treeView->setModel(dirModel);
QModelIndex index = dirModel->index(sPath, 0); // this line is not in the video.
ui->treeView->setRootIndex(index); // this line is not in the video.
fileModel = new QFileSystemModel(this);
fileModel->setFilter(QDir::NoDotAndDotDot | QDir::Files);
dirModel->setRootPath(sPath);
ui->listView->setModel(fileModel);
index = fileModel->index(sPath, 0); // this line is not in the video.
ui->listView->setRootIndex(index); // this line is not in the video.
Just FYI.

You are a blessing, thanks!

[@Roman-uy7qp]

That is sooo much easier than I expected thanks man

[@jpswensen]

Nice video. I wasn't quite sure how QT implemented its MVC and this was a quick browse through how it is done in general and in particular for the TreeView+FileModel

[@lewin555]

Nice one. This is really usefull when indeed you don't want to spend time looking at docs, even they are good quality.
Directly to the essential.

[@madmentat9596]

Thanks, it was quiet comprehensible even though English is not my native language.

[@thickFruitJuice]

Your Tutorial saved me tons of time. Thanx.

[@frikstobal]

hey man, you are the best!!!!!
thank you so much for your tutorials, I like that you explain everything so clearly that is just as learning in college.
: )

Very useful tutorial.
I struggled as the file section was only showing files from the parent directory and didn't get it for a while.
Make sure to use QFileInfo::absoluteFilePath() and not QFileInfo::absolutePath() ...

[@0Wayne]

This is great.
What options are available for network file paths?

[@okbabekhelifi1206]

I'm following the tutorials on QT 5.1, the absolutePath() function didn't work well ti only showed the files for the first subdir of each dir, I changed with absoluteFilePath() and it worked well.

[@ultramanjonez]

This is great. I'm looking for a way to do this using QML. I already have an application that uses a QDeclarativeView object and "setSource(QUrl(/path/main.qml))" to display the GUI drawn with QML. I've got lots of information, but not one example of this done through QML. Any pointers would be appreciated.

[@saperlotteable]

For all the people who just need a file explorer, I would advice this line
QString filePath = QFileDialog::getOpenFileName(this, "select CSV file",".",'Comma Separated Values (*.csv)");
This is for csv file but you can set any extension you want.

[@skinpotatoes]

for new Qt versions :
add #include in the Dialog.h (under header folder)

[@doobzzz]

When you go in directory, then subdirectory in it , then back - QListView show subdirectory even if filter is QDir::Files
What to do with this?

[@BlazeMaddox]

hey, how do you set the path in case of Linux? thanks

[@fugger02]

Very well done!

[@cestarianinhabitant5898]

Thanks, this was exactly what I needed :)

how to open file by doubleclicked on listview?

[@ThanosSiozos]

Excellent! Thank you very much.

[@WilsonTech-go]

everything works fine, just when i debug it my list view and treeview wont expand with the main window. like when i maximize it they stay the same. any help?

[@CasperLiHongKong]

How to make it only show name Column and hide other Columns in the treeview?

[@CasperLiHongKong]

Can you teach me how to initialize the splitter handle position?

[@mrkevinfielding]

I just downloaded and installed the newest Qt IDE. According to qmake --version I am running 4.8.6
The file type QFileSystemModel can not be found though? I get a "unknown type name 'QFileSystemModel'" error
Any help please?

[@yevhenkondrashyn5162]

same

[@krezkort]

Include QFileSystemModel in your h file

[@yevhenkondrashyn5162]

I have done it

[@aliancemd]

It's important to know that not QDir is obsolete but QDirModel.

[@Sinedsem]

Any source code?

[@Lukomeyan]

Thanks for the video. Very helpful, but I'm busy with an assignment where I have to use QFileSystemModel to create folders, delete and rename files and folders. I figured out how to create and delete but I cannot seem to find anything in QFileSystemModel which renames files or folders. Help, anyone?

[@Mohitkapoor5678]

How can I add checkboxes before each file listed in the file explorer view?

[@LITTLESTUDY]

wow~

[@Manas-co8wl]

While this was interesting and informative, it seems impractical to divide up the models like this
