[SOLVED] getSaveFileName()
-
I am using: QString QFileDialog::getSaveFileName()
It opens up a dialog and lets me select the file to save. The problem I am having is putting content into the saved file. I want it to come right out of a textEdit box. Any suggestions? A simple example would really help! -
Hi,
getSaveFileName() gives you just a name. You need open the file and write into it using "QFile":http://doc.qt.io/qt-5/qfile.html.
If your question is about how to keep the formatting of the text in the QTextEdit, than that's a different problem. Your "options":http://doc.qt.io/qt-5/qtextdocumentwriter.html#supportedDocumentFormats are between HTML, plain text and proababy not up-to-date ODF. It is of course obvious that plain text doesn't keep any formatting except paragraphs.

Does this look like it will work?
#include <QtCore>
#include <QtGui>QString mFilename;
QString file = QFileDialog::getSaveFileName(this,"Save a file");
if(!file.isEmpty())
{
mFilename = file;
}QFile sFile(mFilename);
if(sFile.open(QFile::WriteOnly | Qfile::Text)
{
QTextStream out(&sFile);out << ui->textEdit->toPlainText();
sFile.flush();
sFile.close();

}[/quote]It looks OK. QFile::write() should be enough, you don't need QTextStream. Also no need to call flush() or close() since QFile destructor will do both.

Could you provide an example of this, please?

Yes, that is what I was wanting to see. Very cool!!
