PySide2 QUiLoader 返回一个空窗口 [英] PySide2 QUiLoader returns an empty window

问题描述

PySide2(5.6.0~a1) Qt UI 文件加载器返回一个空窗口，而 PyQt5 加载器工作正常.你能向我解释我哪里错了.

PySide2(5.6.0~a1) Qt UI file loader returns an empty window whereare PyQt5 loader works fine. Could you explained to me where I am wrong.

非工作 PySide2 版本:

Non Working PySide2 version:

import sys
from PySide2.QtWidgets import QDialog, QApplication
from PySide2 import QtUiTools

class AppWindow(QDialog):
    def __init__(self):
        super().__init__()
        self.ui = QtUiTools.QUiLoader().load("dialog1.ui")
        self.show()

app = QApplication(sys.argv)
w = AppWindow()
sys.exit(app.exec_())

工作 PyQt5 版本:

Working PyQt5 version:

import sys
from PyQt5.QtWidgets import QDialog, QApplication
from PyQt5 import uic

class AppWindow(QDialog):
    def __init__(self):
        super().__init__()
        self.ui = uic.loadUi("dialog1.ui", self)
        self.show()

app = QApplication(sys.argv)
w = AppWindow()
sys.exit(app.exec_())

使用此功能也不起作用:

Using this function also does not work :

def loadUiWidget(uifilename, parent=None):
    loader = QtUiTools.QUiLoader()
    uifile = QtCore.QFile(uifilename)
    uifile.open(QtCore.QFile.ReadOnly)
    ui = loader.load(uifile, parent)
    uifile.close()
    return ui

推荐答案

QUiLoader().load() 将小部件作为对象返回，因此如果将其分配给变量，它不会执行任何操作，你应该使用 show():

QUiLoader().load() returns the widget as an object so if you assign it to a variable it will not do anything, you should use show():

import sys
from PySide2.QtWidgets import QApplication
from PySide2 import QtUiTools

app = QApplication(sys.argv)
w = QtUiTools.QUiLoader().load("dialog1.ui")
w.show()
sys.exit(app.exec_())
