If all you need is the displayed text in your QTextEdit widget, you can access that by using the toPlainText() method on the widget you need the text from. Example: mytext = self.textEdit.toPlainText() At this point, you can do whatever you want with mytext. You can write it to a file, you can manipulated it, … Read more
As far as I can tell, you can just reference an item using .itemText(): AllItems = [QComboBoxName.itemText(i) for i in range(QComboBoxName.count())]
This answer to this question is as found here: Python PySide (Internal c++ Object Already Deleted) Apparently, assigning one widget to QMainWindow using setCentralWidget and then assigning another widget with setCentralWidget will cause the underlying c++ QWidget to be deleted, even though I have an object that maintains reference to it. Note: QMainWindow takes ownership … Read more
You can derive from widget class and reimplement resizeEvent event
Ok, this code seems to do the trick (i.e. it puts a non-blocking ipython interpreter in a Qt widget, which can be embedded into other widgets). Keywords passed to terminal_widget get added to the namespace of the widget import atexit from IPython.zmq.ipkernel import IPKernelApp from IPython.lib.kernel import find_connection_file from IPython.frontend.qt.kernelmanager import QtKernelManager from IPython.frontend.qt.console.rich_ipython_widget import … Read more
self.folderactive.isChecked isn’t a boolean, it’s a method – which, in a boolean context, will always evaluate to True. If you want the state of the checkbox, just invoke the method: if self.folderactive.isChecked(): … else: …
In your shoes, I wouldn’t fight your framework, just like, as a general principle, I don’t fight City Hall;-). I happen to share your preference for lowercase-with-underscore function names as PEP 8 specifies, but when I’m programming in a framework that forces a different capitalization style, I resign myself to adopting that style too, since … Read more
It’s a good thing you’re using Python, I created a library to do just that a while ago: http://www.hardcoded.net/articles/send-files-to-trash-on-all-platforms.htm On PyPI: Send2Trash Installation Using conda: conda install Send2Trash Using pip: pip install Send2Trash Usage Delete file or folders from send2trash import send2trash send2trash(“directory”)
Override the closeEvent method of QWidget in your main window. For example: class MainWindow(QWidget): # or QMainWindow … def closeEvent(self, event): # do stuff if can_exit: event.accept() # let the window close else: event.ignore() Another possibility is to use the QApplication‘s aboutToQuit signal like this: app = QApplication(sys.argv) app.aboutToQuit.connect(myExitHandler) # myExitHandler is a callable
General Programming Practices If you must use multi-threaded code, never-ever access the GUI from a non-GUI thread. Always instead send a message to the GUI thread by emitting a signal or some other thread-safe mechanism. Be careful with Model/View anything. TableView, TreeView, etc. They are difficult to program correctly, and any mistakes lead to untraceable … Read more
