PYQT:水平和垂直 Headers
PYQT: Horizontal and Vertical Headers
有谁知道如何向 QTableView 添加垂直和水平 headers?我已经为此工作了几个小时,但我似乎无法弄清楚。
当前结果:
但是,我正在尝试制作这个:(抱歉,我在 excel 中制作了它——但是,我希望你能理解)。
这是我的代码:
from PyQt4 import QtCore, QtGui, uic
import sys
try:
from PyQt4.QtCore import QString
except ImportError:
QString = str
SYSTEM=0
class inovaTableModel( QtCore.QAbstractTableModel ):
def __init__(self, data = [[]], headers=[], parent=None):
QtCore.QAbstractTableModel.__init__(self, parent )
self.__data = data
self.__headers = headers
def rowCount(self, parent):
return len(self.__data)
def columnCount(self, parent):
return len(self.__data[0])
def flags(self, index):
return QtCore.Qt.ItemIsEditable | QtCore.Qt.ItemIsEnabled | QtCore.Qt.ItemIsSelectable
def data(self, index, role):
if role == QtCore.Qt.EditRole:
row = index.row( )
column = index.column( )
return self.__data[row][column]
if role == QtCore.Qt.ToolTipRole:
row = index.row( )
column = index.column( )
return self.__data[row][column]
if role == QtCore.Qt.DisplayRole:
row = index.row( )
column = index.column( )
return self.__data[row][column]
def setData(self, index, value, role = QtCore.Qt.EditRole):
if role ==QtCore.Qt.EditRole:
row = index.row()
column = index.column()
self.dataChanged.emit(index, index)
return self.__data[row][column]
def headerData(self, section, orientation, role):
if role == QtCore.Qt.DisplayRole:
if orientation == QtCore.Qt.Horizontal:
return QString("X","Y","Z")
if orientation == QtCore.Qt.Vertical:
return QString("List ") + QString(section)
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
app.setStyle( "plastique" )
data = ["one", "two", "three",]
tableData_alpha = [
["5","1"],
["10", "3"],
]
headers = ["Y", "X", "Z"]
model = inovaTableModel(tableData_alpha)
tableView = QtGui.QTableView()
tableView.show()
tableView.setModel(model)
sys.exit(app.exec_())
我将 headerData 添加到 model-class。我能够使垂直 headers 工作,但不能使水平工作。这是结果:
header 数据是每个 column/row,因此您必须 return 特定部分的 header,而不是所有 3 个。 str("X", "Y", "Z")
str
的使用无效,您只需要 return 由 section
的值标识的那个:
def headerData(self, section, orientation, role):
if role == QtCore.Qt.DisplayRole:
if orientation == QtCore.Qt.Horizontal:
return ["X", "Y", "Z"][section]
if orientation == QtCore.Qt.Vertical:
return QString("List ") + QString(section)
