Problem : save text from text Browser

musti

hello
i tried this code to save text from text browser but it only create a blank text document
@
void MainWindow::fileSave()
{
QFile sFile (mFilename); //mFilename is a QString

        if( !sFile.open (QFile::WriteOnly | QFile::Text&#41;) 
                                    
                                                        return fileSaveAs();

        if(sFile.open(QFile::WriteOnly | QFile::Text)){

                           QTextStream out(&sFile);

                          out<<textView->toPlainText();  ;

            sFile.flush();
            sFile.close();
        }};

   void MainWindow::fileSaveAs()
    {

QString File = QFileDialog::getSaveFileName(this, tr("Save as..."),QString(), tr("txt (*.txt);")) ;

            if (!File.isEmpty()){
                mFilename = File ;
                fileSave();

}};@

i made a button that open a file in the text browser and it work but when i save it again it become blank .

Hi,

You don't do anything if open fails. You should at least use a QMessageBox to show a warning.

On a side note, this pretty much continues this "thread":http://qt-project.org/forums/viewthread/43815/ you should have rather kept it there.

hi
i have no problem with open file my problem is with saving it .
i can save a plaintext with the same code but here i have a textbrowser .
what should i do ?
thank you

SGaist

QTextBrowser is a QTextEdit so it should behave pretty much the same.

One quick way to verify the content of your QTextBrowser is to

@qDebug() << textView->toPlainText();@

Anyway, it's still not a clean technique to open a file twice.

thank you so much :)
the code became :
@
void MainWindow::fileSave()
{
QFile sFile(mFilename);

        if(sFile.open(QFile::WriteOnly | QFile::Text&#41;){
                                QTextStream out(&sFile);

            out <<textView->toPlainText();
         

            sFile.flush();
            sFile.close();
        }};

@
i wish to become an expert like you someday :)

You should still have a at least something that tells you if open failed e.g. you user choose a read-only file.

Keep practicing young one ;) don't hesitate to ask questions to more experienced developers and read documentation (books, Qt's documentation examples etc.)
