QFileDialog error message

[gabor53]

Hi,
I have the following line

    QString newFile = QFileDialog::getOpenFileName(this,tr("Open Image"),QString(),tr("Images (*.png *.xpm *.jpg *.bmp"));

which generates the following error message:
C:\Programming\Projects\Folkfriends_1_0\mydelegate.cpp:167: error: no matching function for call to 'QFileDialog::getOpenFileName(myDelegate*, QString, const char [10], QString)'
QString newFile = QFileDialog::getOpenFileName(this,tr("Open Image"),"/Pictures",tr("Images (*.png *.xpm *.jpg *.bmp"));

I have QFileDialog with the includes.
What is incorrect?
Thank you.

Your first argument type may be wrong. It accepts qwidget type. You must be passing different type
