我想设置复选框边距？结盟

Question

我做了一些Qdialog，当我执行代码时，复选框没有对齐：

但我想要这样：

代码如下：

class SelectPay_Dialog2(Qdialog): 

    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        self.setGeometry(500, 200, 400, 200)
        self.setWindowTitle("Window")


        label1 = QLabel("test  : ")
        label2 = QLabel("test  : ")
        label3 = QLabel("test : ")
        #
        label1.setFixedSize(80, 20)
        label2.setFixedSize(80, 20)
        label3.setFixedSize(80, 20)

        cb1 = QCheckBox('1week')
        cb2 = QCheckBox('2week')
        cb3 = QCheckBox('3week')
        cb4 = QCheckBox('4week')
        cb5 = QCheckBox('5week')
        cb6 = QCheckBox('6week')

        self.input_date_text1 = QLineEdit()
        self.input_date_text2 = QLineEdit()
        self.input_date_text1.setFixedSize(100, 25)
        self.input_date_text2.setFixedSize(100, 25)
        self.input_date_text1.setReadOnly(True)
        self.input_date_text2.setReadOnly(True)

        layout = QGridLayout()
        layout.addWidget(label1, 0, 0)
        layout.addWidget(label2, 2, 0)
        layout.addWidget(label3, 1, 0)

        layout.addWidget(self.input_date_text1, 2, 1)
        layout.addWidget(self.input_date_text2, 2, 2)
   
        layout.addWidget(cb1, 1, 1 )
        layout.addWidget(cb2, 1, 2 )
        layout.addWidget(cb3, 1, 3 )
        layout.addWidget(cb4, 1, 4)
        layout.addWidget(cb5, 1, 5)

        self.setLayout(layout)

Answer 1

顾名思义，QGridLayout 将项目放置在具有行和列的 grid 中。如果您更仔细地查看图像，您会发现前两个复选框与行编辑对齐。

如果你不想要这种行为，那么你有不同的选择，它们都使用 QHBoxLayout：

1. 根本不使用网格布局，而是使用QVBoxLayout作为主布局，并为每个“行”添加QHBoxLayout；这样做的缺点是第一个“列”可能未对齐，这似乎是您的情况的要求；
2. 使用 QFormLayout，addRow 右侧有 QHBoxLayout；
3. 添加具有正确列跨度的 QHBoxLayout；

第三种情况可能对您通常在右侧“侧”有固定数量的小部件的情况很有用。
将两行编辑视为“默认”布局安排，这就是您的情况：

    checkLayout = QHBoxLayout()
    layout.addLayout(checkLayout, 1, 1, 1, 3)
    checkLayout.addWidget(cb1)
    checkLayout.addWidget(cb2)
    checkLayout.addWidget(cb3)
    checkLayout.addWidget(cb4)
    checkLayout.addWidget(cb5)

请注意，我使用的列跨度为 3。这确保了布局占用 3 列，并且由于实际上只有两列被占用（由行编辑），结果是剩余空间将仅用于复选框所需的 remaining 宽度。

类似的相关解决方案需要将行编辑添加到它们自己的 QHBoxLayout，但还要在它们之后使用addStretch()，以便在它们的右侧保持空白。

对于复杂的布局，我推荐使用 Qt 设计器。您可以使用pyuic5 工具将使用它创建的ui 文件转换为python 代码。

main.py

from PyQt5 import QtWidgets, QtCore

from Ui_SelectPay_Dialog2 import Ui_SelectPay_Dialog2

class SelectPay_Dialog2(QtWidgets.QDialog):
    def __init__(self, parent = None):
        super().__init__(parent)
        ui = Ui_SelectPay_Dialog2()
        ui.setupUi(self)

if __name__ == "__main__":
    app = QtWidgets.QApplication([])
    widget = SelectPay_Dialog2()
    widget.show()
    app.exec_()

Ui_SelectPay_Dialog2.py

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_SelectPay_Dialog2(object):
    def setupUi(self, SelectPay_Dialog2):
        SelectPay_Dialog2.setObjectName("SelectPay_Dialog2")
        SelectPay_Dialog2.resize(432, 150)
        self.gridLayout = QtWidgets.QGridLayout(SelectPay_Dialog2)
        self.gridLayout.setObjectName("gridLayout")

        sizePolicy.setHeightForWidth(self.label.sizePolicy().hasHeightForWidth())
        self.label.setSizePolicy(sizePolicy)

Answer 3

你写layout.addWidget(cb1, 1, 1 )的地方你的括号间距与layout.addWidget(cb4, 1, 4)不同，使它们都相等，它应该修复它
