所以,我在Maya中使用python和PySide2来定制工具。
我有一个模型(QTableModel)和一个QTableView。
模型中的每一行都有一组信息和一个复选框。
我需要做一个QItemDelegate并将其用作复选框。没关系。我很难知道是否检查了该代表。
我迭代模型以获取其数据(将其存储在节点中的Maya场景中)
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)
每行中的第一项恰好是一个复选框(委托)。在最后一个数据数组中,我最终得到了实际的QItemDelegate对象,而我真的想得到它的状态,无论是否选中,但它没有isChecked()方法。
关于如何做到这一点的想法?
非常感谢你!

因此,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
我想我是做错了代表,我承认,我在网上发现了这个snnipet,我正在努力理解它。。。。但事情是这样的:
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中:
self.setItemDelegateForColumn(0, CBDelegate(self))
有帮助吗?(如果你有maya 2017,我可以给你完整的代码……这有点乱,因为我把它作为一个学习练习!
非常感谢。

表视图:
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))
型号:
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)
代理位于上面的编辑1中。
那么我想您仍然需要周期和标题来启动此模型:
headers = ["Select", " Cycle Name ", " Start ", " End ", "Info", "Version", " Del "]
cycles = [[False,"idle","1","70","cool information","0", "deleteBtnPlaceHolder"]]
我希望这样做。
非常感谢。

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为字典,以便将其序列化并存储为Autodesk Maya中节点的字符串属性。它运行正常,但它从第一列获得的信息总是没有。我必须以不同的方式检索它吗?
