Question

更新上一个问题。

当显示这看起来非常狭窄时，请参见下面的照片。

我想保持QWidget（面板）的高度相同，并在其右侧添加一个QScrollBar，这样小部件就会自然缩小，用户可以向下滚动

我尝试添加此代码。

scroll = QtGui.QScrollArea()
scroll.setWidget(widget)
scroll.setWidgetResizable(True)
scroll.setFixedHeight(400)
layout.addWidget(scroll)

但是代码运行，但是没有GUI打开，所以我手动强制从命令行停止它。

工作代码如下所示。

谢谢

buildTCPPanal()

您必须在放置QScrollArea的位置创建一个新窗口小部件，并显示该新窗口小部件。将PyQt4和PySide的元素组合在一起也不合适。另一个不好的做法是在函数中使用超出该范围的元素。

from PyQt4 import QtGui, QtCore
import sys

app = QtGui.QApplication(sys.argv)


def buildTCPPanal():
    widget = QtGui.QWidget()
    layout = QtGui.QGridLayout()
    vbox1 = QtGui.QVBoxLayout()

    button = QtGui.QPushButton("Send")

    flag1 = QtGui.QCheckBox("CWR")
    flag2 = QtGui.QCheckBox("ECN")
    flag3 = QtGui.QCheckBox("URG")
    flag4 = QtGui.QCheckBox("ACK")
    flag5 = QtGui.QCheckBox("PSH")
    flag6 = QtGui.QCheckBox("RST")
    flag7 = QtGui.QCheckBox("SYN")
    flag8 = QtGui.QCheckBox("FIN")

    textEdit1 = QtGui.QTextEdit('')
    textEdit2 = QtGui.QTextEdit('')
    textEdit3 = QtGui.QTextEdit('')
    textEdit4 = QtGui.QTextEdit('')
    #textEdit5 = QtGui.QTextEdit('')#using check boxes instead
    textEdit6 = QtGui.QTextEdit('')

    label1 = QtGui.QLabel("IP Destanation Address")
    label2 = QtGui.QLabel("IP Source Address")
    label3 = QtGui.QLabel("Source Port")
    label4 = QtGui.QLabel("Destanation Port")
    label5 = QtGui.QLabel("Flags")
    label6 = QtGui.QLabel("Data")

    layout.addWidget(label1) #dest add
    layout.addWidget(textEdit1)

    layout.addWidget(label2) #src add
    layout.addWidget(textEdit2)

    layout.addWidget(label3) #src port
    layout.addWidget(textEdit3)

    layout.addWidget(label4) #dest port
    layout.addWidget(textEdit4)

    layout.addWidget(label5) #flags
    layout.addWidget(flag1)
    layout.addWidget(flag2)
    layout.addWidget(flag3)
    layout.addWidget(flag4)
    layout.addWidget(flag5)
    layout.addWidget(flag6)
    layout.addWidget(flag7)
    layout.addWidget(flag8)


    layout.addWidget(label6)
    layout.addWidget(textEdit6)

    runCommandButton = QtGui.QPushButton("Send Packet")
    runCommandButton.setObjectName("runCommandButton")

    vbox1.addLayout(layout)
    vbox1.addWidget(runCommandButton)
    #QtCore.QObject.connect(runCommandButton, QtCore.SIGNAL("clicked()"), createScapyCommand)

    widget.setLayout(vbox1)
    widget.show()

    w = QtGui.QWidget()
    layout = QtGui.QVBoxLayout(w)
    scroll = QtGui.QScrollArea()

    scroll.setWidget(widget)
    scroll.setWidgetResizable(True)
    scroll.setFixedHeight(400)
    layout.addWidget(scroll) 
    w.show()

    sys.exit(app.exec_())


buildTCPPanal()

在Python中将QScrollBar添加到狭窄的QWidget中
