проблема с ScrollArea в Pyqt с использованием QtDesigner

Question

Я разработал окно с QtDesigner и добавил в него прокрутку и макет, но область прокрутки не прокручивается, она показывает полосу прокрутки, но она не может быть прокручена вообще.

from PyQt4 import QtCore, QtGui 

try: 
    _fromUtf8 = QtCore.QString.fromUtf8 
except AttributeError: 
    def _fromUtf8(s): 
     return s 

try: 
    _encoding = QtGui.QApplication.UnicodeUTF8 
    def _translate(context, text, disambig): 
     return QtGui.QApplication.translate(context, text, disambig, _encoding) 
except AttributeError: 
    def _translate(context, text, disambig): 
     return QtGui.QApplication.translate(context, text, disambig) 
class StartQT4(QtGui.QMainWindow): 
    def __init__(self, parent=None): 
     QtGui.QWidget.__init__(self, parent) 
     self.ui = Ui_MainWindow() 
     self.ui.setupUi(self) 

class Ui_MainWindow(object): 

def setupUi(self, MainWindow): 
    MainWindow.setObjectName(_fromUtf8("MainWindow")) 
    MainWindow.resize(767, 600) 
    self.centralwidget = QtGui.QWidget(MainWindow) 
    self.centralwidget.setObjectName(_fromUtf8("centralwidget")) 
    self.pushButton = QtGui.QPushButton(self.centralwidget) 
    self.pushButton.setGeometry(QtCore.QRect(230, 300, 75, 23)) 
    self.pushButton.setObjectName(_fromUtf8("pushButton")) 
    self.lineEdit = QtGui.QLineEdit(self.centralwidget) 
    self.lineEdit.setGeometry(QtCore.QRect(80, 330, 371, 71)) 
    self.lineEdit.setObjectName(_fromUtf8("lineEdit")) 
    MainWindow.setCentralWidget(self.centralwidget) 
    self.menubar = QtGui.QMenuBar(MainWindow) 
    self.menubar.setGeometry(QtCore.QRect(0, 0, 767, 21)) 
    self.menubar.setObjectName(_fromUtf8("menubar")) 
    MainWindow.setMenuBar(self.menubar) 
    self.statusbar = QtGui.QStatusBar(MainWindow) 
    self.statusbar.setObjectName(_fromUtf8("statusbar")) 
    self.scrollArea = QtGui.QScrollArea(self.centralwidget) 
    self.scrollArea.setGeometry(QtCore.QRect(130, 70, 301, 191)) 
    self.scrollArea.setWidgetResizable(True) 
    self.scrollArea.setMinimumSize(QtCore.QSize(100, 100)) 
    self.scrollArea.setObjectName(_fromUtf8("scrollArea")) 
    self.scrollAreaWidgetContents = QtGui.QWidget() 
    self.scrollAreaWidgetContents.setGeometry(QtCore.QRect(0, 0, 299, 189)) 
    self.scrollAreaWidgetContents.setObjectName(_fromUtf8("scrollAreaWidgetContents")) 
    self.scrollAreaWidgetContents.setMinimumSize(QtCore.QSize(100, 100)) 
    self.scrollArea.setWidget(self.scrollAreaWidgetContents) 
    self.scrollArea.setVerticalScrollBarPolicy(QtCore.Qt.ScrollBarAlwaysOn) 
    self.scrollArea.setHorizontalScrollBarPolicy(QtCore.Qt.ScrollBarAlwaysOff) 
    self.horizontalLayoutWidget = QtGui.QWidget(self.scrollAreaWidgetContents) 
    self.horizontalLayoutWidget.setGeometry(QtCore.QRect(-1, -1, 301, 191)) 
    self.horizontalLayoutWidget.setObjectName(_fromUtf8("horizontalLayoutWidget")) 
    self.horizontalLayout = QtGui.QVBoxLayout(self.horizontalLayoutWidget) 
    self.horizontalLayout.setObjectName(_fromUtf8("horizontalLayout")) 



    p= QtGui.QPalette() 
    p.setColor(QtGui.QPalette.Background, QtCore.Qt.white) 
    self.scrollArea.setAutoFillBackground(True) 
    self.scrollArea.setPalette(p) 
    self.retranslateUi(MainWindow) 

def retranslateUi(self, MainWindow): 
    MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow", None)) 
    self.pushButton.setText(_translate("MainWindow", "send", None)) 

Я хочу, чтобы добавить метки и это, как я делаю это

from main_ui import * 
import sys 
global height 
height=10 
def send(): 
     global height 
     label=QtGui.QLabel(myapp.ui.horizontalLayoutWidget) 
     label.setGeometry(QtCore.QRect(10, height, 46, 13)) 
     height=height+label.height() 
     label.setText(myapp.ui.lineEdit.text()) 
     label.show() 


try: 
    _fromUtf8 = QtCore.QString.fromUtf8 
except AttributeError: 
    def _fromUtf8(s): 
     return s 
app = QtGui.QApplication(sys.argv) 
myapp = StartQT4() 

myapp.show() 
QtCore.QObject.connect(myapp.ui.pushButton, QtCore.SIGNAL(_fromUtf8("clicked()")), send) 
myapp.setCentralWidget(myapp.ui.centralwidget) 
QtCore.QMetaObject.connectSlotsByName(myapp) 
sys.exit(app.exec_())

Сэр, ваш код немного перепутались.

Вот небольшой пример, посмотрите, работает ли он. Нет секретов. : D

это в PyQt5. Вы просто должны изменить свой импорт на PyQt4.

import sys 

from PyQt5.QtCore import Qt 
from PyQt5.QtWidgets import QApplication 
from PyQt5.QtWidgets import QScrollArea 
from PyQt5.QtWidgets import QVBoxLayout 
from PyQt5.QtWidgets import QWidget 


class WSlideBar(QWidget): 
    """WSlideBar is a personalized slide bar.""" 

    w_container = None 
    v_layout_container = None 
    v_scroll_area = None 
    v_layout_preview = None 


    def __init__(self): 
     """Init UI.""" 

     super(WSlideBar, self).__init__() 
     self.init_ui() 

    def init_ui(self): 
     """Init all ui object requirements.""" 


     self.setFixedSize(100,500) 

     self.setStyleSheet(""" 
      background: gray; 
     """) 

     # Container Widget 
     self.w_container = QWidget() 
     self.w_container.setFixedWidth(100) 

     # Layout of Container Widget 
     self.v_layout_container = QVBoxLayout() 
     self.v_layout_container.setSpacing(100) 

     aux = QWidget() 
     aux.setFixedSize(10,10) 
     aux.setStyleSheet("""background: red;""") 

     aux2 = QWidget() 
     aux2.setFixedSize(20, 20) 
     aux2.setStyleSheet("""background: blue;""") 

     aux3 = QWidget() 
     aux3.setFixedSize(15, 15) 
     aux3.setStyleSheet("""background: yellow;""") 

     aux4 = QWidget() 
     aux4.setFixedSize(50,50) 
     aux4.setStyleSheet("""background: rgb(0,255,0,30%);""") 

     aux5 = QWidget() 
     aux5.setFixedSize(40, 40) 
     aux5.setStyleSheet("""background: green;""") 

     aux6 = QWidget() 
     aux6.setFixedSize(40, 40) 
     aux6.setStyleSheet("""background: green;""") 

     self.v_layout_container.addWidget(aux) 
     self.v_layout_container.addWidget(aux2) 
     self.v_layout_container.addWidget(aux3) 
     self.v_layout_container.addWidget(aux4) 
     self.v_layout_container.addWidget(aux5) 
     self.v_layout_container.addWidget(aux6) 

     self.w_container.setLayout(self.v_layout_container) 

     self.v_scroll_area = QScrollArea(self) 
     self.v_scroll_area.setVerticalScrollBarPolicy(Qt.ScrollBarAlwaysOn) 
     self.v_scroll_area.setHorizontalScrollBarPolicy(Qt.ScrollBarAlwaysOff) 
     self.v_scroll_area.setWidget(self.w_container) 

     # Scroll Area Layer add 
     self.v_layout_preview = QVBoxLayout() 
     self.setLayout(self.v_layout_preview) 

     self.v_layout_preview.addWidget(self.v_scroll_area) 

def run(): 
    app = QApplication(sys.argv) 
    GUI = WSlideBar() 
    GUI.show() 
    sys.exit(app.exec_()) 


run() 

OBS:Вы просто должны меняться объекты QPushButton, QLabels, ... вместо маленьких QWidgets и все, что вам нужно.
