我使用Qt的設計師來設計UI(文件:tree_view_widget_ui.py),我有一個類(文件:tree_view_widget.py)創建窗口小部件並顯示數據,但數據不顯示。誰能告訴我我做錯了什麼。PyQt的QTreeWidget不顯示內容
tree_view_widget.py
from tree_view_widget_ui import Ui_Form
class TreeViewWidget(QWidget):
def __init__(self, data2show):
QtGui.QWidget.__init__(self,parent)
self.ui = Ui_Form()
self.ui.setupUi(self)
self.data2show = data2show
self.addItems(self.ui.treeWidget.invisibleRootItem()) #not sure about this line?
def addItems(self, parent):
column = 0
data_group_1 = self.addParent(parent, column, 'Group1', 'data Clients')
for data in self.data2show:
self.addChild(data_item, column, data.prop1, data.prop2)
def addParent(self, parent, column, title, data):
item = QtGui.QTreeWidgetItem(parent, [title])
item.setData(column, QtCore.Qt.UserRole, data)
item.setChildIndicatorPolicy(QtGui.QTreeWidgetItem.ShowIndicator)
item.setExpanded (True)
return item
def addChild(self, parent, column, title, data):
item = QtGui.QTreeWidgetItem(parent, [title])
item.setData(column, QtCore.Qt.UserRole, data)
return item
和GUI設計文件(使用Qt Designer創建):
tree_view_widget_ui.py
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 Ui_Form(object):
def setupUi(self, Form):
Form.setObjectName(_fromUtf8("TreeView"))
Form.setEnabled(True)
Form.resize(200, 400)
Form.setFixedSize(200, 400)
self.treeWidget = QtGui.QTreeWidget(Form)
self.treeWidget.setEnabled(True)
self.treeWidget.setGeometry(QtCore.QRect(0, 0, 200, 400))
self.treeWidget.setFrameShadow(QtGui.QFrame.Sunken)
self.treeWidget.setLineWidth(1)
self.treeWidget.setMidLineWidth(0)
self.treeWidget.setAutoScrollMargin(16)
self.treeWidget.setIndentation(1)
self.treeWidget.setRootIsDecorated(True)
self.treeWidget.setUniformRowHeights(True)
self.treeWidget.setAnimated(False)
self.treeWidget.setColumnCount(0)
self.treeWidget.setObjectName(_fromUtf8("treeWidget"))
self.treeWidget.header().setVisible(False)
self.treeWidget.setHeaderHidden(True)
self.retranslateUi(Form)
QtCore.QMetaObject.connectSlotsByName(Form)
def retranslateUi(self, Form):
Form.setWindowTitle(_translate("Tree View", "Tree View", None))
self.treeWidget.setSortingEnabled(False)
任何建議如何改變數據將以樹狀顯示的代碼?
