Question

我正在使用PyQt4和Qt4Designer开发一个应用程序，我是从设计器和生成的python代码设计的。如下图所示，当我添加第一行时，它占用了整个布局空间，但后来的行具有固定宽度。

显示实际问题的图片

这是我的代码......

from PyQt4.QtCore import QRegExp
from PyQt4.QtGui import QHeaderView
from PyQt4.QtGui import QTableWidgetItem

from main import Ui_MainWindow, QtCore, QtGui
import sys
from newtask import Ui_NewTask


class MainWindow(QtGui.QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)
        resolution = QtGui.QDesktopWidget().screenGeometry()
        # positioning window to center
        self.move((resolution.width() / 2) - (self.frameSize().width() / 2),
                  (resolution.height() / 2) - (self.frameSize().height() / 2))
        self.setupUi(self)
        # Customizing Columns in Table
        rowHeader = self.tableWidget.horizontalHeader()
        rowHeader.setResizeMode(0, QHeaderView.ResizeToContents)
        rowHeader.setResizeMode(1, QHeaderView.Stretch)
        rowHeader.setResizeMode(2, QHeaderView.Stretch)
        rowHeader.setResizeMode(3, QHeaderView.ResizeToContents)
        # self.tableWidget.resizeColumnsToContents()
        # self.tableWidget.resizeRowsToContents()
        # When clicked on Add Task button

        def showDialog():
            newdialog = NewTask(parent=self)
            newdialog.show()
            if newdialog.exec_():
                # adding rows to the table
                for i in range(len(newdialog.data)):
                    currentrow = self.tableWidget.rowCount()
                    self.tableWidget.insertRow(currentrow)
                    for j in range(len(newdialog.data[i])):
                        self.tableWidget.setItem(currentrow, j, newdialog.data[i][j])

        self.AddTask.clicked.connect(showDialog)

        header = self.tableWidget.verticalHeader()
        header.setResizeMode(0, QHeaderView.Stretch)
        # header.setDefaultSectionSize(12)

我有另一个继承QDialog的类，它有很多代码，不想让这个复杂，不发布它...你可以看到当点击AddTask按钮时我将信号连接到showDialog函数。我在那里添加行，我不知道我在哪里做错了，我尝试了以下所有方法。

self.tableWidget.resizeColumnsToContents()
self.tableWidget.resizeRowsToContents()

OR

header.setResizeMode(QHeaderView.Stretch)

OR

header.setResizeMode(QHeaderView.Fixed)

OR

self.tableWidget.rowHeight(20)

OR

self.tableWidget.resizeColumnsToContents()
self.tableWidget.resizeRowsToContents()

他们都没有工作......请帮忙......

EDIT1：

当我尝试在qtdesigner中添加行时，面临同样的问题，将图像附加到此处

Answer 1

可能self.tableWidget.verticalHeader().setStretchLastSection(True)导致问题。

QTablewidget第一排占用更多空间
