问题 I can't find a good answer for this: is there a way for double click to execute a certain function, and single click one other function?? For example: def func1(self): print('First function') def func2(self): print('Second function') self.ui.button.clicked.connect(self.func1) self.ui.button.doubleClicked.connect(self.func2) I've seen double clicking is possible for the QTreeview but not a QPushButton . Thanks! 回答1: You can add the functionality easily yourself by extending QPushButton class:

问题 I have an app with two buttons start and end . The start button will start a thread, which runs the audio recording function. This function is written using sounddevice and soundfile libraries. The audio recording can take place for an arbitary duration and the user can stop anytime by pressing ctrl+c . So, now I want to implement a function for the end button to stop the thread which started by pressing start button or the function can send ctrl+c signal to the thread. So, that the current

问题 After much googling I'm aware that I need to use self.setWindowFlags(QtCore.Qt.FramelessWindowHint) to generate a frameless window, and some variation of the co-ordinates (0,0) to place it in the upper left corner of the screen. The problem I'm having is that everywhere that I've tried using this code, it generates errors, even in my sparse existing code: from PyQt4 import QtCore, QtGui from ui.mainwindow import MainWindow if __name__ == "__main__": import sys app = QtGui.QApplication(sys

问题 I am new to Python and this is my fist Python class. I am using PyQt4 framework on Windows 7. I don't know whether the few lines of code below is correctly written or not.

I will be passing the x-coord., y-coord. and the name of the window to position on the screen. How to modify the code to fulfill these requirements? Edited Further class PositionWindow: def __init__(self,

问题 Is there a way to display other language characters in PyQt4? and if there is, what's the approach/direction that I should take? Thanks in advance. 回答1: Qt uses Unicode and should be able to display (Unicode) text in any language you have a suitable font for. For example, Roberto Alesina's simple "Hello World" program on the PyQt Wiki -- which I transcribe for readability (and w/o the comments for brevity) since it's pretty unreadable in the wiki -- should let you use as the button's text any
