我使用 uic 模組直接讀取 ui 檔案. 好處:

• 一個ui對應一個py檔案
• 直接修改ui, 然後執行py檔案即可

不好的地方在於, ui裡面的資訊在編輯的時候不會有提示.

1. 建立兩個ui檔案: main.ui 和testDialog.ui
2. testDialog.py

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

class testDialog(QDialog):
    def __init__(self):
        super(testDialog,
 
 self).__init__()
        loadUi('testDialog.ui', self)
        self.bt_1.clicked.connect(self.changeText)
        self.show()

    def changeText(self):
        self.bt_1.setText('你點選了我')

3. main.py

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.uic import loadUi


class
 
 main(QMainWindow):
    def __init__(self):
        super(main, self).__init__()
        loadUi('main.ui', self)
        self.bt_showTestDialog.clicked.connect(self.showTestDialog)
        self.show()

    def showTestDialog(self):
        from testDialog import testDialog
        d = testDialog()
        d.
 
exec_()


if __name__ == '__main__':
    app = QApplication(sys.argv)
    main = main()
    sys.exit(app.exec_())

這樣直接執行就可以了

另外還有一個 snippets. 做完ui檔案後, 新建一個和ui同名的py檔案. 輸入gui_main / gui_dialog 自動根據檔名生成程式碼:

	"Python GUI main": {
		"prefix": "gui_main",
		"body": [
			"import sys",
			"from PyQt5.QtWidgets import QApplication, QMainWindow",
			"from PyQt5.uic import loadUi",
			"",
			"",
			"class ${1:$TM_FILENAME_BASE}(QMainWindow):",
			"\tdef __init__(self):",
			"\t\tsuper($1, self).__init__()",
			"\t\tloadUi('$1.ui', self)",
			"\t\t$2",
			"\t\tself.show()",
			"",
			"",
			"if __name__ == '__main__':",
			"\tapp = QApplication(sys.argv)",
			"\tmain = $1()",
			"\tsys.exit(app.exec_())",
		],
		"description": "Python GUI 自動生成 main"
	},
	"Python GUI dialog": {
		"prefix": "gui_dialog",
		"body": [
			"import sys",
			"from PyQt5.QtWidgets import QApplication, QDialog",
			"from PyQt5.uic import loadUi",
			"",
			"",
			"class ${1:$TM_FILENAME_BASE}(QDialog):",
			"\tdef __init__(self):",
			"\t\tsuper($1, self).__init__()",
			"\t\tloadUi('$1.ui', self)",
			"\t\t$2",
			"\t\tself.show()",
			"",
			"",
			"if __name__ == '__main__':",
			"\tapp = QApplication(sys.argv)",
			"\tmain = $1()",
			"\tsys.exit(app.exec_())",
		],
		"description": "Python GUI 自動生成 dialog"
