问题 I am building a UI with QT Designer. I need this UI to run on a Raspberry Pi. What do I need to do to make the UI for the Pi?

问题 Im new to all this and all im trying to do is make a little file that looks decent, has a exit button and a launch button that when you hit it, it launches two other .exe files and closes. I also tried to make it launch but I saw that with the current path it would only work on my computer and not anyone elses. Here is my code so far: import tkinter as tk from PyQt5 import QtCore, QtGui, QtWidgets import sys import os from PyQt5.QtWidgets import * from PyQt5.QtGui import * import PyQt5.QtCore

问题 I'd like to display a Form into a mainWindow tab. The mainWindow is already created and filled with empty tabs, and the Form is also created and filled with empty comboBox, labels and such. The mainWindow is called home and the Form listInvoice. They work well on their own, but when I call listInvoice from the home tab, it opens a new window displaying the listInvoice GUI instead of displaying listInvoice within the tab. Do you know how to call a form from within a mainWindow tab? Thank you

问题 I'm trying to change the Icon of a QpushButton on hover and pressed, I'm using QtDesigner with stylesheets.

I tried setting it from QtDesigner Menu but it didn't work as well. 回答1: Unfortunately, it is a bug of Qt which is still not fixed. There's a workaround suggestion within the comments to that bug, basically you could use empty

问题 I am loading a QMainWindow from an .ui file - it's working fine but window events like resize won't be triggered. I can't really figure out what I am doing wrong. This is the code: class TestWindow(QMainWindow): def __init__(self, parent=None): super(TestWindow, self).__init__(parent) loader = QUiLoader() file = QFile(abspath("ui/mainwindow.ui")) file.open(QFile.ReadOnly) self.window = loader.load(file, parent) file.close() self.window.show() def resizeEvent(self, event): print "resize" app =
