无意中创建一个小部件

我的系统主窗口有一个GUI类。我已将名为“viewEvidenceButton”的按钮链接到名为“openReportViewer”的函数，以便在单击该按钮时打开报告查看器窗口。我注意到在主窗口上，它创建了一个类似方形的小部件，就像我在运行程序时窗口左上角没有文本的按钮一样。为什么这样做，我怎么能阻止这种情况发生。这是我的主要GUI窗口代码。

答案 0 :(得分：1)

问题是因为您正在创建2个按钮：

# # View Evidence Button
self.viewEvidenceButton = QtWidgets.QPushButton(self.centralwidget)
font = QtGui.QFont()
font.setFamily("Arial")
font.setPointSize(12)
font.setBold(True)
font.setWeight(75)
self.viewEvidenceButton.setFont(font)
self.viewEvidenceButton = QtWidgets.QPushButton(self.centralwidget) # <--- remove this line
self.viewEvidenceButton.setObjectName("viewEvidenceButton")

删除按钮的第二次创建，因此该按钮不会出现。
