PyQT5 空白窗口
[英]PyQT5 Blank WIndow
问题描述
我用 python 为勾股定理创建了一个计算器，并决定我应该为它制作一个 GUI。 我想要一些可以拖放 GUI 的东西，因为我之前尝试过 Tkinter，这真的很难。 我用 QT 设计器创建了一个 GUI，然后开始对按钮进行编码，但由于某种原因，它不能与 Pycharm 一起使用我收到错误 ImportError: DLL load failed: The specified module can not be found the specified module could not be found every time I run the code ，所以如果你能解决这个问题，请回复。 当我尝试在 MU 文本编辑器中运行它时，它运行良好。 所以我开始编写按钮来做某事，但是当我运行代码时，窗口是空的。 请帮忙。 谢谢，Famous8。 这是我的第一篇文章 ：）
编码：

这里也是 PTCGUI 的内容，包含所有信息的文件

在您的代码中：
- 你不是子类化你的 MainWindow。 在名称 == 主要部分。 你需要
MainWindow()而不是QtWidgets.QMainWindow()
我还建议您将变量命名为与您的班级不同的名称
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
MyWindow = MainWindow()
MyWindow.show()
sys.exit(app.exec_())
你的类应该继承 QMainWindow。 你的 init 应该像这样开始
class MainWindow(QMainWindow): def __init__(self): super().__init__() self.ui = PTCGUI.Ui_MainWindow() self.ui.setupUi(self)删除
def show(self)。 你不需要调用self.ui.show()，你只想直接调用self.show()。
