QtDesigner를 사용하여 Pyqt에서 ScrollArea 문제가 발생했습니다.

Question

QtDesigner를 사용하여 창을 디자인하고 스크롤 영역과 레이아웃을 추가했지만 스크롤 영역이 스크롤되지 않으면 스크롤 막대가 표시되지만 전혀 스크롤 할 수 없습니다.

내가 레이블을 추가 할이 내가 그것을

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_())

에게 선생님을 어떻게, 코드는 엉망 비트입니다.

작은 예제입니다. 작동하는지 확인하십시오. 비밀은 없습니다. : D

PyQt5에 있습니다. 수입품을 PyQt4로 바꾸면됩니다.

OBS : 당신은 그냥 당신이 필요로하는 어떤 QPushButtons, QLabels, ... 대신 작은 QWidgets 및 위해 변경해야합니다.
