As an AI language model, I cannot open PyQt5 designer because I do not have access to a graphical user interface. However, I can provide you the steps to start PyQt5 designer for creating user interfaces:

1. Install PyQt5: You need to have PyQt5 library installed in your system. You can install it via pip command `pip install pyqt5`

2. Open the PyQt5 Designer: Once installed, you can open the PyQt5 Designer by running the command `pyqt5-tools designer` in the command prompt or terminal.

3. Start creating a user interface: Once the designer window is open, you can start creating a user interface by dragging and dropping widgets from the left pane to the central pane. You can customize the properties of the widgets from the right pane.

4. Save and export the UI file: After creating the user interface, you can save the UI file in .ui format. You can also export the UI file to Python code using the `pyuic5` command.

pyqt5designer显示图片

你可以使用PyQt5 Designer来显示图片。首先，你需要将一个QLabel控件添加到你的窗口中。然后，通过设置QLabel的pixmap属性，将图片加载到QLabel中。这里是一个简单的示例代码，演示了如何在PyQt5 Designer中显示图片：

from PyQt5 import QtWidgets, QtGui

class MyWindow(QtWidgets.QMainWindow):
    def __init__(self):
        super().__init__()
        self.setupUi()

    def setupUi(self):
        self.setWindowTitle("Image Viewer")

        # 创建QLabel控件
        self.label = QtWidgets.QLabel(self)
        self.setCentralWidget(self.label)

        # 加载图片并显示在QLabel中
        pixmap = QtGui.QPixmap("path_to_your_image.jpg")
        self.label.setPixmap(pixmap)
        self.label.setScaledContents(True)  # 自适应窗口大小

if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    window = MyWindow()
    window.show()
    sys.exit(app.exec_())

请将"path_to_your_image.jpg"替换为你要显示的图片的实际路径。运行这个代码，你将看到一个带有图片的窗口。记得在PyQt5 Designer中添加一个QMainWindow窗口，并将该窗口的类指定为MyWindow。
