qfiledialog

问题 I've got a problem with saving file with extension (get path to file and append extension) in PyQt4 with QFileDialog. My Python code looks like that: dialog = QtGui.QFileDialog() dialog.setDefaultSuffix(".json") file = dialog.getSaveFileName(None, "Title", "", "JSON (.json)") It works, path is correct, dialog title and filter are in dialog window, but second line was ignored. File doesn't have any extension. How to add extension by default? What am I doing wrong? 回答1: Calling setDefaultSuffix

问题 I'm using the code below to build a qstringlist of filenames: QStringList filenames = QFileDialog::getOpenFileNames(this,"",QDir::currentPath() ); How can I change this so I can select directories as well? I looked at: dialog.setFileMode(QFileDialog::AnyFile); but I don't get how to use it with my code. 回答1: This code snippet linked in the comment above solves my issue. QFileDialog* _f_dlg = new QFileDialog(this); _f_dlg->setFileMode(QFileDialog::Directory); _f_dlg->setOption(QFileDialog:

问题 (Windows 7 64 Bit, PyCharm 3.4.1 Pro, Python 3.4.0, PySide 1.2.2) I want to make a file dialog with filters and preselect one filter.

问题 In Qt, QFileDialog *dlg = new QFileDialog(); QDir dir = dlg->getExistingDirectory(this, tr("Choose folder"), qgetenv("HOME")); opens a folder choose dialog. Once I select a folder (press choose button) the folder is not closing automatically. So I tried: if(dlg->close() == true) delete(dlg); When I debug the dlg->close() returns true and the code delete(dlg) is hit. Still the Folder chooser dialog box is not closing.

问题 I'm trying to use a QFileDialog to prompt a user to provide a filename and location to save a text file at. I played around with the QtGui.QFileDialog.getSaveFileName, but I was interested in using some of the options, like setting the default suffix, and enabling the Detail view of the save file dialog, which, from what I could tell, isn't possible to do, using the getSaveFileName alone. Whenever I set those, the getSaveFileName dialog just ignored them. So, I ended up with something like
