Include a button to open .tif image

[john_hobbyist]

Hello,

I use this code: https://github.com/kklmn/OrthoView/blob/master/OrthoView.py

what changes should I do, so that I can import the image file via putting a button and choosing the file. Because now I use the image file by putting the path into the code. I need to open the file through a button in order to choose different images when I run the code... I am reading this code: https://www.tutorialspoint.com/pyqt/pyqt_qfiledialog_widget.htm in order to understand the basics... Thank you

The solution already is on your linked site:

Use QFileDialog to pick the image and trigger the dialog with your button.

self.btn = QPushButton("QFileDialog static method demo")
self.btn.clicked.connect(self.getfile)

def getfile(self):
      fname = QFileDialog.getOpenFileName(self, 'Open file', 'C:\\',"Image files (*.jpg *.gif)")
      // DO SOMETHING WITH YOUR IMG

Hi
well did you add the button to your main screen ?
To a layout most likely.

Just creating the button wont show it anywhere :)

If you mean this:

layout.addWidget(self.btn)

I have added it.

Yep that seems ok.

But I cannot see the button to open file...
update: Ok I fixed it! Thanks a lot for your time...

This error:

NameError: name 'QFileDialog' is not defined

means that I need to import something from PyQt5 ?

Answer: Yes :-)
