Widget 在 GridLayout 中相互重叠

Question

我正在尝试使用 GridLayout 创建一个简单的程序，QWidget window 中的所有小部件确实显示并正确缩放，但是 LineEdit 与window 的标题 Label。

from PySide2 import QtWidgets, QtCore, QtGui
import sys

class SimGrid(QtWidgets.QWidget):
    def __init__(self):
        super(SimGrid, self).__init__()
        self.setWindowTitle("My attempt at Grid Layout")
        grid = QtWidgets.QGridLayout()
        self.setLayout(grid)

        title = QtWidgets.QLabel("This is some big sample text to fill up")
        title.setAlignment(QtCore.Qt.AlignHCenter)
        text_edit = QtWidgets.QTextEdit()
        success = QtWidgets.QPushButton("Success", self)
        cancel = QtWidgets.QPushButton("Cancel", self)

        grid.addWidget(title, 0, 0, 0, 0)
        grid.addWidget(text_edit, 1, 0, 1, 2)
        grid.addWidget(success, 4, 0)
        grid.addWidget(cancel, 4, 1)
        self.show()

Answer 1

根据docs您正在使用以下方法：

void QGridLayout::addWidget(QWidget *widget, int fromRow, int fromColumn, int rowSpan, int columnSpan, Qt::Alignment alignment = ...)

第三个和第四个参数分别表示将占用的数量和列，在您的情况下，标题将占用 0 行和 0 列，这是不正确的。

使用这些条件你想要的是：

import sys
from PySide2 import QtWidgets, QtCore, QtGui


class SimGrid(QtWidgets.QWidget):
    def __init__(self):
        super(SimGrid, self).__init__()
        self.setWindowTitle("My attempt at Grid Layout")
        grid = QtWidgets.QGridLayout()
        self.setLayout(grid)

        title = QtWidgets.QLabel("This is some big sample text to fill up")
        title.setAlignment(QtCore.Qt.AlignHCenter)
        text_edit = QtWidgets.QTextEdit()
        success = QtWidgets.QPushButton("Success", self)
        cancel = QtWidgets.QPushButton("Cancel", self)

        grid.addWidget(title, 0, 0, 1, 2)
        grid.addWidget(text_edit, 1, 0, 1, 2)
        grid.addWidget(success,2, 0, 1, 1)
        grid.addWidget(cancel,  2, 1, 1, 1)
        self.show()


if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    w = SimGrid()
    w.show()
    sys.exit(app.exec_())
