PictureFlow is a Qt4 (and PyQt4) widget that allows "awesome" listing of images. PyQt4 bindings are only available in the SVN code (download tar.gz snapshot) that you can get from:
svn export http://pictureflow.googlecode.com/svn/trunk/ pictureflow
To compile and install PictureFlow use:
- Go to pictureflow-qt folder and execute: qmake, make and make install
- Go to pyqt folder and execute: python configure.py, make, make install
import sys
from os import listdir
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from pictureflow import *
app = QApplication(sys.argv)
w = PictureFlow()
images = listdir('/path/to/folder/with/images/')
for i in images:
if i.endswith('jpg'):
w.addSlide(QPixmap('/path/to/folder/with/images/%s' % i))
w.show()
sys.exit(app.exec_())
