问题 I'm trying to pop up a context menu when a user right-clicks on an item in a QListView and a different context menu if the user right-clicks outside of any of the items (any of the whitespace). What I'm finding is that the index I'm receiving when performing the indexAt command is not accurate, and I can't figure out why. I initialize the QListView as its own class: class RBKDataTypesTab(QWidget): def __init__(self): super().__init__() self.models = [] grid = QGridLayout() self.list =

问题 I would like to align texts in a QTableWidget on the left side, but I would also like to add an indent so the text isn't stuck against the border. On the image, col_2 is what I want. And I would like the same for the header labels. from PyQt5 import QtCore, QtGui, QtWidgets from PyQt5.QtWidgets import QTableWidgetItem class Ui_Form(object): def setupUi(self, Form): Form.setObjectName("Form") Form.resize(400, 300) self.gridLayout = QtWidgets.QGridLayout(Form) self.gridLayout.setObjectName(

问题 I applied border width and border color via setStyleSheet funciton in pyqt5. But when I use it in frameless window, border not applied. any issue in my code? I need help. Here comes my code. import sys from PyQt5.QtWidgets import QWidget,QApplication from PyQt5.QtCore import Qt,QPoint class CommonFramelessWidget(QWidget): def __init__(self,parent): super(CommonFramelessWidget,self).__init__(parent) self.setWindowFlags(Qt.Window|Qt.FramelessWindowHint) self.setStyleSheet('border:5px black;

问题 I am building a larger program in PyQt5. I want to create a large number of clickable QPushButtons in a ScrollArea. As far as I can see it, the program works so far, but gets very slow, when the number of buttons gets high (about 10,000 to 20,000 characters). How can I ensure that this program builds these buttons responsive? I need to load textfiles separated by chars as QPushButtons which are usually about 15-20 kb large (sometimes up to 50 kb). I believe, this should not be a size

问题 I have an app that's designed to help synchronise an experiment video and data signals. The App has a video widget and a slider that can set the temporal position of the video. However, QMediaPlayer will only set the position at 500mSec/1000mSec intervals (in my app 500mSec/in the contrived app 1000mSec) while the video is shot at 50fps implying 20mSec intervals. This makes synchronisation pretty useless. I've added an output of the position before and after the position change. Any help

问题 I have a QWizard that reads the column headers of a CSV file and makes the user choose what they want with each column. In the 2nd page of this wizard, I add the combo-boxes in a for loop that loops over the column names of the CSV. All combo-boxes are mandatory fields. However, another constraint is that at least one of them must be selected to choice 3 or above (c1 or c2 in my MWE), before the user can press "Next". In addition to self.NextButton.setEnabled(False) , I also tried using

问题 Good night. I have seen some programs with new borderless designs and still you can make use of resizing. At the moment I know that to remove the borders of a pyqt program we use: QtCore.Qt.FramelessWindowHint And that to change the size of a window use QSizeGrip. But how can we resize a window without borders? This is the code that I use to remove the border of a window but after that I have not found information on how to do it in pyqt5. I hope you can help me with an example of how to
