Hey there,

i am actually having big troubles to get a QListWidget to work, so that it resizes (expands) vertically but to a minimum required size.
It should adjust if the QListWidget expands horizontally. So, in general it should just request for the space it's childs request. Did try to find a solution for the whole day and the closest i was able to get was this:

Qt Code: 
  1. import sys
  2. from PySide import QtGui, QtCore
  3.  
  4. if __name__ == '__main__':
  5.     app = QtGui.QApplication([])
  6.  
  7.     window = QtGui.QWidget()
  8.     layout = QtGui.QVBoxLayout(window)
  9.  
  10.  
  11.  
  12.     list = QtGui.QListWidget()
  13.  
  14.     sizePolicy = QtGui.QSizePolicy(QtGui.QSizePolicy.Expanding,
  15.                                    QtGui.QSizePolicy.Ignored)
  16.     sizePolicy.setHorizontalStretch(0)
  17.     sizePolicy.setVerticalStretch(0)
  18.     sizePolicy.setHeightForWidth(list.sizePolicy().hasHeightForWidth())
  19.  
  20.     list.setSizePolicy(sizePolicy)
  21.     list.setFocusPolicy(QtCore.Qt.NoFocus)
  22.     list.setFrameShape(QtGui.QFrame.NoFrame)
  23.     list.setLineWidth(0)
  24.     list.setAutoScroll(False)
  25.     list.setProperty("showDropIndicator", False)
  26.     list.setDragDropMode(QtGui.QAbstractItemView.NoDragDrop)
  27.     list.setSelectionMode(QtGui.QAbstractItemView.NoSelection)
  28.     list.setSelectionBehavior(QtGui.QAbstractItemView.SelectRows)
  29.     list.setMovement(QtGui.QListView.Free)
  30.     list.setFlow(QtGui.QListView.LeftToRight)
  31.     list.setProperty("isWrapping", True)
  32.     list.setResizeMode(QtGui.QListView.Adjust)
  33.     list.setLayoutMode(QtGui.QListView.Batched)
  34.     list.setViewMode(QtGui.QListView.ListMode)
  35.     list.setSelectionRectVisible(True)
  36.     list.setHorizontalScrollBarPolicy(QtCore.Qt.ScrollBarAlwaysOff)
  37.     list.setVerticalScrollBarPolicy(QtCore.Qt.ScrollBarAlwaysOff)
  38.  
  39.     for i in range(2):
  40.         item = QtGui.QListWidgetItem()
  41.         widget = QtGui.QWidget()
  42.  
  43.         widget_layout = QtGui.QHBoxLayout()
  44.         edit = QtGui.QLineEdit()
  45.         label = QtGui.QLabel("I love PyQt!")
  46.         widget_layout.addWidget(label)
  47.         widget_layout.addWidget(edit)
  48.         widget_layout.addStretch()
  49.         widget_layout.setSizeConstraint(QtGui.QLayout.SetFixedSize)
  50.         widget.setLayout(widget_layout)
  51.         item.setSizeHint(widget.sizeHint())
  52.         list.addItem(item)
  53.         list.setItemWidget(item, widget)
  54.  
  55.  
  56.     list.setFixedSize(list.sizeHintForColumn(0) + 2 * list.frameWidth(), list.sizeHintForRow(0) * list.count() + 2 * list.frameWidth())
  57.  
  58.     layout.addWidget(list)
  59.     window.show()
  60.  
  61.     sys.exit(app.exec_())

Hope someone can help me here ...
