如何在 PyQt5 中围绕多种形式构建框架？

  • 772

有一个用于输入文本的程序label和表格。qlineedit

下面是左边的程序照片和右边的程序照片，上面Paint'е画了一个框架（实际上，你需要像右图那样做）：

我知道如何为label带有文本的简单边框添加边框，但我不知道如何为label+添加边框qlineedit...请帮助。下面是程序代码：

导入系统
从 PyQt5.QtWidgets 导入 QMainWindow、QWidget、QGridLayout、QApplication
从 PyQt5.QtGui 导入 QIcon
从 PyQt5.QtWidgets 导入 QWidget、QPushButton、QLabel、QHBoxLayout、QVBoxLayout、\
    QRadioButton、QButtonGroup、QMessageBox、QApplication、QLineEdit、QFormLayout
从 PyQt5.QtCore 导入 Qt
从 PyQt5.QtGui 导入 QFont、QIcon、QPixmap

窗口高度 = 450
窗口宽度 = 300
WINDOW_NAME = 'KWUR'
WINDOW_ICON_NAME = '图片\\main_logo.png'


MAIN_FONT = '时间'
FONT_HEADER_SIZE = 13
FONT_BODY_SIZE = 8


类FormBuilder（QWidget）：
    def __init__(self, parent=None):
        super().__init__(父)

        self.create_all_forms()
        self.fill_forms()
        self.create_layers()

    def create_all_forms(self):
        self.heading_label = QLabel()
        self.entering_label = QLabel()

        self.first_value = QLineEdit()
        self.second_value = QLineEdit()
        self.third_value = QLineEdit()

        self.find_button = QPushButton('查找')
        self.clear_button = QPushButton('清除')

    定义填充表格（自我）：
        self.heading_label.setText('二次解')
        self.heading_label.setFont(QFont(MAIN_FONT, FONT_HEADER_SIZE, QFont.Bold))

        self.entering_label.setText('输入系数：')
        self.entering_label.setFont(QFont(MAIN_FONT, FONT_HEADER_SIZE))

        self.first_value.setText('值 1')
        self.first_value.setFixedSize(265, 20)
        self.second_value.setText('值 2')
        self.second_value.setFixedSize(265, 20)
        self.third_value.setText('值 3')
        self.third_value.setFixedSize(265, 20)

    def create_layers(self):
        main_layout = QVBoxLayout(self)

        标题标签 = QHBoxLayout()
        heading_label.addWidget(self.heading_label)
        main_layout.addLayout(heading_label)

        entry_label = QHBoxLayout()
        enter_label.addWidget(self.entering_label)
        main_layout.addLayout(entering_label)

        first_qline_edit = QHBoxLayout()
        first_qline_edit.addWidget(self.first_value)
        main_layout.addLayout(first_qline_edit)

        second_qline_edit = QHBoxLayout()
        second_qline_edit.addWidget(self.second_value)
        main_layout.addLayout(second_qline_edit)

        third_qline_edit = QHBoxLayout()
        third_qline_edit.addWidget(self.third_value)
        main_layout.addLayout(third_qline_edit)

        线 = QFormLayout()
        line.addRow(self.find_button, self.clear_button)


类主窗口（QMainWindow）：
    def __init__(self):
        超级（）.__init__（）

        self.centralWidget = QWidget()
        self.setCentralWidget(self.centralWidget)

        self.build_skeleton_with_basic_settings()
        self.create_and_connect_grid()

    def build_skeleton_with_basic_settings(self):
        self.setFixedSize(WINDOW_WIDTH, WINDOW_HEIGHT)
        self.setWindowTitle(WINDOW_NAME)
        self.setWindowIcon(QIcon(WINDOW_ICON_NAME))

    def create_and_connect_grid(self):
        self.main_grid = QGridLayout(self.centralWidget)
        form_builder_object = FormBuilder()
        self.main_grid.addWidget(form_builder_object, 0, 0, Qt.AlignTop)


如果 __name__ == '__main__'：
    应用程序 = QApplication(sys.argv)
    例如 = 主窗口（）
    ex.show()
    sys.exit(app.exec_())
python

    作为一种选择：

    QGroupBox小部件提供了一个带有标题的组框框架。
