    <p>I am trying to get a path with the <code>QtGui.QFileDialog.getExistingDirectory()</code> dialog window in a <code>python</code> program to ease things up for users while the rest of the program is in console output. I have this piece of code for this purpose:</p> <pre><code>import sys, os from PyQt4 import QtGui def getpath(filename, noPathFileMsg='', wrongFolderMsg='', selectFolderMsg=''): try: f = open('./'+filename,'r') except IOError: folder = get_new_path(filename, noPathFileMsg, selectFolderMsg) else: folder = f.readline() f.close() currentDir = os.getcwd() try: os.chdir(folder) except: folder = get_new_path(filename, wrongFolderMsg, selectFolderMsg) else: os.chdir(currentDir) finally: return folder def get_new_path(filename, infoMsg, selectFolderMsg): app = QtGui.QApplication(sys.argv) QtGui.QMessageBox.about(None, 'No folder', infoMsg) folder = QtGui.QFileDialog.getExistingDirectory(None, selectFolderMsg) app.exit() if os.name == 'posix': folder += '/' elif os.name == 'nt': folder += '\\' g = open('./'+filename,'w') g.write(folder) g.close() return folder if __name__ == '__main__': folderPath = getpath('pathtofolder.txt', noPathFileMsg='The path to the folder has not been set', wrongFolderMsg='The path folder saved cannot be reached', selectFolderMsg='Please select a folder') print folderPath var = input('The program stopped at the input instruction, the dialog window should now be closed!') </code></pre> <p>If I call the getpath function the dialog window stays open until the script that called the function ends instead of closing just after this instruction:</p> <pre><code>folder = QtGui.QFileDialog.getExistingDirectory(None, selectFolderMsg) </code></pre> <p>If you run this code it will create a file that saves the directory saved with the dialog window in the folder where the script is run.</p> <p>What did I do wrong?</p> <p>By the way, I am on Ubuntu 12.04. Thank you! Cheers</p>

    1. COI cannot reproduce the problem you describe using the code you've posted (testing on Linux).

    2. COI added a __main__ statement with some code so that the error seams more obvious. The Window should be closed when the program stops for input from the command line.

    3. COIt's not obvious at all. Sequence of events for me: 1. run script. 2. message box appears ("the path to the folder has not been set"). 3. file dialog appears. 4. select folder, click ok. 5. file dialog closes. 6. console prints the selected folder and input instruction.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
