PyQt5将QLabel插入QLabel

Question

我正在尝试创建一个接口，并希望在Qlabel中插入qlabel和Qbutton，同时像QVBoxLayout和QHBoxLayout一样保留调整大小的功能。

这是我想要完成的，但随着规模的改变，就像QVBoxLayout和QHBoxLayout一样。

​

我的代码：

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(604, 460)
        self.verticalLayout = QtWidgets.QVBoxLayout(Form)
        self.verticalLayout.setContentsMargins(0, 0, 0, 0)
        self.verticalLayout.setSpacing(0)
        self.verticalLayout.setObjectName("verticalLayout")
        self.frame = QtWidgets.QFrame(Form)
        self.frame.setFrameShape(QtWidgets.QFrame.StyledPanel)
        self.frame.setFrameShadow(QtWidgets.QFrame.Raised)
        self.frame.setObjectName("frame")
        self.verticalLayout_2 = QtWidgets.QVBoxLayout(self.frame)
        self.verticalLayout_2.setContentsMargins(0, 0, 0, 9)
        self.verticalLayout_2.setSpacing(0)
        self.verticalLayout_2.setObjectName("verticalLayout_2")
        self.label = QtWidgets.QLabel(self.frame)
        self.label.setStyleSheet("QLabel {\n"
"background-color: #09102a;\n"
" }")
        self.label.setText("")
        self.label.setObjectName("label")
        self.verticalLayout_2.addWidget(self.label)
        self.frame_2 = QtWidgets.QFrame(self.frame)
        self.frame_2.setMaximumSize(QtCore.QSize(16777215, 70))
        self.frame_2.setFrameShape(QtWidgets.QFrame.StyledPanel)
        self.frame_2.setFrameShadow(QtWidgets.QFrame.Raised)
        self.frame_2.setObjectName("frame_2")
        self.horizontalLayout = QtWidgets.QHBoxLayout(self.frame_2)
        self.horizontalLayout.setObjectName("horizontalLayout")
        self.label_2 = QtWidgets.QLabel(self.frame_2)
        self.label_2.setMinimumSize(QtCore.QSize(120, 60))
        self.label_2.setMaximumSize(QtCore.QSize(120, 60))
        self.label_2.setStyleSheet("QLabel {\n"
"    font: 75 13pt \"MS Shell Dlg 2\";\n"
"    padding-right :5px;\n"
"    padding-left :5px;\n"
"    image: url(:/icons/images/icons/battery-monitoring.png);\n"
"    image-position: left;\n"
"    background-color: #171d3c;\n"
"    border-radius :20px;\n"
"    color: rgb(255, 255, 255);\n"
" }")
        self.label_2.setAlignment(QtCore.Qt.AlignRight|QtCore.Qt.AlignTrailing|QtCore.Qt.AlignVCenter)
        self.label_2.setObjectName("label_2")
        self.horizontalLayout.addWidget(self.label_2)
        self.label_3 = QtWidgets.QLabel(self.frame_2)
        self.label_3.setMinimumSize(QtCore.QSize(120, 60))
        self.label_3.setMaximumSize(QtCore.QSize(120, 60))
        self.label_3.setStyleSheet("QLabel {\n"
"    font: 75 13pt \"MS Shell Dlg 2\";\n"
"    padding-right :5px;\n"
"    padding-left :5px;\n"
"    image: url(:/icons/images/icons/battery-charger.png);\n"
"    image-position: left;\n"
"    background-color: #171d3c;\n"
"    border-radius :20px;\n"
"    color: rgb(255, 255, 255);\n"
" }")
        self.label_3.setAlignment(QtCore.Qt.AlignRight|QtCore.Qt.AlignTrailing|QtCore.Qt.AlignVCenter)
        self.label_3.setObjectName("label_3")
        self.horizontalLayout.addWidget(self.label_3)
        self.verticalLayout_2.addWidget(self.frame_2)
        self.verticalLayout.addWidget(self.frame)

        self.retranslateUi(Form)
        QtCore.QMetaObject.connectSlotsByName(Form)

    def retranslateUi(self, Form):
        _translate = QtCore.QCoreApplication.translate
        Form.setWindowTitle(_translate("Form", "Form"))
        self.label_2.setText(_translate("Form", "label 2"))
        self.label_3.setText(_translate("Form", "label 1"))


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    Form = QtWidgets.QWidget()
    ui = Ui_Form()
    ui.setupUi(Form)
    Form.show()
    sys.exit(app.exec_())

在执行代码之后，我得到了以下内容：

我想得到的结果。当屏幕放大时，所有元素都必须就位，这不能由QVBoxLayout和QHBoxLayout完成。

对于PyQt6..。我用这个“黑客”来做你要做的事，因为我没有适当的技能，所以我用QLabels做任何事情。

from PyQt6           import QtCore, QtWidgets
from PyQt6.QtCore    import QEvent, QObject, pyqtSignal
import sys

class Trigger(QObject):
    event_highjack = pyqtSignal()

    def __init__(s, eventparent, master_fn=None, resize=False, move=False, mousebutton=False, close=None, fn=None):
        super().__init__(eventparent)
        for enum in [k for k,v in {14:resize, 13:move, 19:close, 2:mousebutton}.items() if v]:
            s.eventtype = QEvent.type(QEvent(enum))
        s.master_fn = master_fn or fn
        s._widget = eventparent
        s.widget.installEventFilter(s)
        if s.master_fn:
            s.event_highjack.connect(s.master_fn)

    @property
    def widget(s):
        return s._widget

    def eventFilter(s, widget, event) -> bool:
        if widget == s._widget and event.type() == s.eventtype:
            s.event_highjack.emit()
        return super().eventFilter(widget, event)

class Main(QtWidgets.QMainWindow):
    def __init__(s, *args, **kwargs):
        super().__init__(styleSheet='background:black;color:white', *args, **kwargs)
        s.show()

        label = QtWidgets.QLabel(s, styleSheet='background:magenta')
        label.show()

        def follow_master():
            label.setGeometry(10,10,s.width()-20,s.height()-20)

        Trigger(s, resize=True, fn=follow_master)

if '__main__' in __name__:
    app = QtWidgets.QApplication(sys.argv)
    window = Main()
    app.exec()

我会使用Qt设计器来创建guis。你可以随心所欲地放置所有的东西，并让它随你的意愿移动。另外，gui编码和python编码是分开的，然后它更容易维护。您可以用uic.loadUi加载gui (r“yourgui.ui”，self)
