Under the folder "very big" consist 8448 jpg, when I using a tool(Bulk rename utility) to rename the
jpg under "very big", the program will crash. How could I stop the self updating function of QFileSystemModel?
Thanks

Added after 5 minutes:

I want to told QFileSystemModel don't update the data even there are files being renamed
Do I have to reimplement some functions of QFileSystemModel?Thanks

Is this question too advance or my courtesy is no good?
I ask other questions about QFileSystemModel on this forum but rarely get responses

If I violate the rules or lack of courtesy, please tell me and I promise I will
change.Thank you very much

1 : I find out the QDirModel will not update until you call "refresh"

2 : even I do not setup the model for the view, rename the files will affect
the main thread(GUI) seriously.No wonder why even I rename the files
on another thread, the GUI still stall.

int main( int argc, char **argv )
{  
    QApplication app( argc, argv );
 
    QFileSystemModel model;
 
    QString const rootPath = "E:/file_test/very big";
    model.setRootPath(rootPath);       
 
    QTableView view;
    //I haven't set any model for The view, but the program still
    //crash if I rename 8448 of my jpg files by other program    
 
    QSplitter splitter;
    splitter.addWidget(&view);   
    splitter.show();
 
    return app.exec();
}

int main( int argc, char **argv )
{  
    QApplication app( argc, argv );

    QFileSystemModel model;

    QString const rootPath = "E:/file_test/very big";
    model.setRootPath(rootPath);       

    QTableView view;
    //I haven't set any model for The view, but the program still
    //crash if I rename 8448 of my jpg files by other program    
    
    QSplitter splitter;
    splitter.addWidget(&view);   
    splitter.show();

    return app.exec();
}

There are still more than 1XX pages of the model/view architecture I have to studied(advanced Qt programming)
I hope I could know how to prevent the automatic "refresh" function of the QFileSystemModel after
I finish the chapter 4, 5, 6 in the book

QDirModel is not a good solution, but looks like it could solve my problem for now.

Never expect that customize the model/view of Qt4 could be so complicated(2XX pages to study)
And I am still a newbie of Qt...
