QItemDelegate复选框

因此，我在Maya中使用python和PySide2作为自定义工具。

我有一个模型（QTableModel）和一个QTableView。

模型中的每一行都会有一堆信息和一个复选框。

我要做一个QItemDelegate并将其用作复选框。那也行。我无法获取是否已检查该代表的麻烦。

我遍历该模型以获取其数据（将其存储在节点的Maya场景内）

    data = []
    rows = self.rowCount(1) #self is the model in this snnipet
    for row in range(rows):
        array = []
        for column in range (6): #6 for the fixed number of columns
            info = index.data()
            array.append(index.data())
        data.append(array)

碰巧每行的第一项是一个复选框（代表）。在最终的数据数组中，当我真正想要获取其状态（是否经过检查）但没有isChecked（）方法时，最终得到了实际的QItemDelegate对象。

关于如何得到的想法？

非常感谢你！

因此，该模型确实具有注释中提到的标志：

def flags(self, index):
        return QtCore.Qt.ItemIsEditable | QtCore.Qt.ItemIsEnabled | QtCore.Qt.ItemIsSelectable | QtCore.Qt.ItemIsUserCheckable

我认为我做错了代表，正如我承认的那样，我在线上找到了这个snnipet，并且我试图理解它……。但是它像这样：

class CBDelegate(QItemDelegate):

def __init__(self, parent):

    QItemDelegate.__init__(self, parent)


def paint(self, painter, option, index):

    self.cb = QCheckBox()

    try:
        self.cb.setChecked(index.data())
    except:
        pass

    if not self.parent().indexWidget(index):
        self.parent().setIndexWidget(index, self.cb)

然后在TableView上：

 self.setItemDelegateForColumn(0, CBDelegate(self))

有帮助吗？（如果您有Maya 2017，我可以给您完整的代码...这有点混乱，因为我将其用作学习练习！

谢谢。

表格检视：

class Table(QTableView):
    def __init__(self, *args, **kwargs):
        QTableView.__init__(self, *args, **kwargs)

        # Set the delegate for column 0 of our table
        #self.setItemDelegateForColumn(6, ButtonDelegate(self)) #problem for another time
        self.setItemDelegateForColumn(0, CBDelegate(self))

模型：

class Model(QtCore.QAbstractTableModel):

    def __init__(self, cycles = [[]], headers = [], parent = None):
        QtCore.QAbstractTableModel.__init__(self, parent)

        self.cycles = cycles
        self.headers = headers

    def rowCount(self, parent):

        return len(self.cycles)

    def columnCount(self, parent):
        return len(self.cycles[0])

    def flags(self, index):
        return QtCore.Qt.ItemIsEditable | QtCore.Qt.ItemIsEnabled | QtCore.Qt.ItemIsSelectable | QtCore.Qt.ItemIsUserCheckable

    def data(self, index, role):

        if role == QtCore.Qt.DisplayRole:

            row = index.row()
            column = index.column()
            value = self.cycles[row][column]
            return value

        if role == QtCore.Qt.EditRole:

            row = index.row()
            column = index.column()
            return self.cycles[row][column]

        if (role == QtCore.Qt.TextAlignmentRole):
            return QtCore.Qt.AlignCenter;

    def setData(self, index, value, role = QtCore.Qt.EditRole):

        change = False

        if role == QtCore.Qt.EditRole:

            row = index.row()
            column = index.column()

            value = value

            if (column == 1) or (column == 4):
                try:
                    str(value)
                    change = True
                except:
                    pm.warning("Not a valid name")
                    change = False
            elif (column == 2):
                try:
                    int(value)
                    change = True
                except:
                    pm.warning("Not a valid frame")
                    change = False
            elif (column == 3):
                try:
                    int(value)
                    change = True
                except:
                    pm.warning("Not a valid frame")
                    change = False

            elif (column == 5):
                try:
                    int(value)
                    change = True
                except:
                    pm.warning("Not a valid version number")
                    change = False

            if change:
                self.cycles[row][column] = value
                self.dataChanged.emit(row, column)
                return True

            return False            

    def headerData(self, section, orientation, role):

        if role == QtCore.Qt.DisplayRole:

            if orientation == QtCore.Qt.Horizontal:
                return self.headers[section]

    def insertRows(self, position, rows, values = [] , parent = QtCore.QModelIndex()):


        self.beginInsertRows(parent, position, position+rows-1)

        self.cycles.insert(position, values)

        self.endInsertRows()

        self.getData()



    def getData(self):

        rows = self.rowCount(1)

        data = []

        for row in range(rows):
            array = []
            for column in range (6):
                index = self.index(row, column)
                info = index.data()

                if type(info) == bool:
                    array.append(info)

                elif type(info) == QItemDelegate:
                    val_is_checked = index.data(QtCore.Qt.CheckStateRole) != QtCore.Qt.Unchecked
                    array.append(val_is_checked)

                else:
                    info = str(info)
                    array.append(info)

            array.append("del")
            data.append(array)

        dic = {}
        for item in data:
            dic[item[1]]=item

        for key in dic:
            print key, dic[key]


        #this from pickle
        #newData = data2String(dic)
        # and this is what I wanna save inside Maya
        #pm.setAttr("cycleAnimationListNode.cycles", newData)

委托位于上方的“编辑1”中。

然后，我猜您仍然需要循环和标头来启动此模型：

headers = ["Select", "  Cycle Name  ", " Start ", "  End  ", "Info", "Version", " Del "]

cycles = [[False,"idle","1","70","cool information","0", "deleteBtnPlaceHolder"]]

我希望这样做。

谢谢。

我在模型中有此自定义方法：

def getData(self):
        rows = self.rowCount(1)
        data = []
        for row in range(rows):
            array = []
            for column in range (6):
                index = self.index(row, column)
                info = index.data()
                array.append(info)              
            data.append(array)

        dic = {}
        for item in data:
            dic[item[1]]=item

        print ""
        print "data:"
        print ''
        for key in dic:
            print(key, dic[key])

我使用它将模型转换成字典，因此可以序列化并将其存储为Autodesk Maya中Node的字符串属性。它运行正常，但从第一列获取的信息始终为“无”。我是否必须以其他方式检索它？
