在下面的例子:PyQt的beginremoverows
from PyQt4 import QtCore, QtGui
class Ui_Dialog(QtGui.QDialog):
def __init__(self,parent=None):
QtGui.QDialog.__init__(self,parent)
self.setObjectName("Dialog")
self.resize(600, 500)
self.model = QtGui.QDirModel()
self.tree = QtGui.QTreeView()
self.tree.setModel(self.model)
print(self.model.flags(self.model.index("c:\Program Files")))
self.model.setFilter(QtCore.QDir.Dirs|QtCore.QDir.NoDotAndDotDot)
self.tree.setSortingEnabled(True)
self.tree.setRootIndex(self.model.index("c:\Program Files"))
#self.tree.hideColumn(1)
#self.tree.hideColumn(2)
#self.tree.hideColumn(3)
self.tree.setWindowTitle("Dir View")
self.tree.resize(400, 480)
self.tree.setColumnWidth(0,200)
self.tree.show()
QtCore.QObject.connect(self.tree, QtCore.SIGNAL("clicked(QModelIndex)"), self.test)
QtCore.QMetaObject.connectSlotsByName(self)
self.setWindowTitle(QtGui.QApplication.translate("Dialog", "Dialog", None, QtGui.QApplication.UnicodeUTF8))
def test(self,index):
print(self.model.filePath(index))
print(self.model.rowCount(index))
#self.model.beginRemoveRows(index.parent(),index.row(),self.model.rowCount(index))
#self.model.endRemoveRows()
print("Row of the index =",index.row())
print("Parent = ",self.model.data(index.parent()))
if __name__ == "__main__":
import sys
app = QtGui.QApplication(sys.argv)
ui = Ui_Dialog()
#ui.show()
sys.exit(app.exec_())
我想刪除的行和它的孩子(如果有的話),當我點擊它。
(下點擊它的孩子文件夾都將被免職。)
我知道我在這條線會犯錯:
self.model.beginRemoveRows(index.parent(),index.row(),self.model.rowCount(index))
感謝您的時間。
您能解釋上下文嗎?你是否刪除文件等? – PedroMorgan 2011-03-10 00:36:32
