The path after saving a file is not the default path when saving again in the QFileDialog.

I have the following codes in my QFileDialog for windows. What I want to do is when I save my "sample.txt" file. I want to save the next file to the path where I saved the previous file.

QString file = QFileDialog::getSaveFileName(this,tr("Notepad- Save file"),"Untitled.txt",
tr("Text Files (*txt)");

****When I write my codes like this.
--> QString file = QFileDialog::getSaveFileName(this,tr("Notepad- Save file")," ",
tr("Text Files (*txt)");

***removing the "Untitled.txt" would work but the title for the filename will disappear. I want my QFileDialog to be perfect as the filedialog in the Microsoft word. Where the filename field has a temporary filename and the file would save to the path where I save the previous projects. How am I suppose to do that?

Opening the QFileDialog using the static method QFileDialog::getSaveFileName(...) is stateless, so the dialog does not remember the last used directory. You have to store it separately and pass it as third argument (you can specify a complete path, not just a filename).

QString lastFile = ....; // e.g. /home/xyz/Documents/myFile.txt
QString newFile = QDir(lastFile).absolutePath().filePath(tr("Untitled.txt")); // set a temporary name
QString file = QFileDialog::getSaveFileName(this,tr("Notepad- Save file"), newFile, tr("Text Files (*txt)");

good day thank you so much for your help but I am having an error with this part...

QString newFile = QDir(lastFile).absolutePath().filePath(tr("Untitled.txt")); // set a temporary name

QT says that Class QString has no member named filepath.

I do appreciate your help but I hope you can help me with this one too. Thank you so much.

Hi,

That's because absolutePath returns a QString. You're likely looking for QDir::absoluteFilePath

Ouch, right. I did not try it, I was just typing the demo code before having the first cup of coffee ;-)
But following this approach is the right way...

Thank you guys for help. I'm trying out the codes but still got some errors and still trying to figure out the solution. But thanks guys.
