WxPython ListCtrl 索引 0 项不可编辑

Question

self.testParameters = self.testParameterListCtrl(self, -1, style=wx.LC_REPORT      |wx.LC_HRULES | wx.LC_VRULES | wx.LC_SINGLE_SEL)
self.testParameters.InsertColumn(0, "Parameter", wx.LIST_FORMAT_CENTER, -1)
self.testParameters.InsertColumn(1, "Value", wx.LIST_FORMAT_CENTER, -1)
self.testParameters.Bind(wx.EVT_LIST_END_LABEL_EDIT, self.onModifyTestParameter )

for parameter, value in self.keywordArgs.iteritems():
        self.testParameters.InsertStringItem(index, parameter, 0)
        self.testParameters.SetStringItem(index, 1, str(value))
        if parameter in self.workloadTests.values():
            self.testParameters.SetStringItem(index, 1, self.testWorkload.GetValue())
        # Cell Colors
        if (index % 2): 
            self.testParameters.SetItemBackgroundColour(index, self.listBGColor_1)
        else:
            self.testParameters.SetItemBackgroundColour(index, self.listBGColor_2)
        index += 1

在此代码中，我想禁用“0”索引 "parameter" 作为不可编辑的 listCtrl 和“1”索引“值”作为可编辑的 listCtrl。

Answer 1

您可以使用

中的 EditableListCtrl 来执行此操作

import wx.lib.mixins.listctrl as listmix

为

中的混音创建 class

class EditableListCtrl(wx.ListCtrl, listmix.TextEditMixin):
    # TextEditMixin allows any column to be edited other than those specifically vetoed
    def __init__(self, parent, ID=wx.ID_ANY, pos=wx.DefaultPosition,
                 size=wx.DefaultSize, style=0):
        """Constructor"""
        wx.ListCtrl.__init__(self, parent, ID, pos, size, style)
        listmix.TextEditMixin.__init__(self)

将您的 listctrl 定义为可编辑

self.listCtrl = EditableListCtrl(my_panel1, -1, style=wx.LC_REPORT|wx.LC_SINGLE_SEL|wx.LC_VRULES, size=(1145,285))

然后绑定某些项目的否决权：self.listCtrl.Bind(wx.EVT_LIST_BEGIN_LABEL_EDIT, self.OnVetoItems)

定义你的否决权

def OnVetoItems(self, event): 
    if event.m_itemIndex == 0:
        event.Veto()
        return

注意也可以使用 event.m_col 并检查 listctrl

中的列号来否决列

使用 wx.ListCtrls 几乎总是一件痛苦的事。我建议您尝试使用 ObjectListView 而不是

General usage.

Cell editing

示例：

#!python3
import wx
from ObjectListView import ObjectListView, ColumnDefn

random_objects = [
    {"parameter": "Test", "value": "1"},
    {"parameter": "Test2", "value": "2"}
]


class MainFrame(wx.Frame):
    def __init__(self):
        super(MainFrame, self).__init__(parent=None, title="OLV Test")
        panel = MainPanel(self)
        self.Show()


class MainPanel(wx.Panel):
    def __init__(self, parent):
        super(MainPanel, self).__init__(parent)

        self.olv = ObjectListView(parent=self, style=wx.LC_REPORT | wx.BORDER_SUNKEN, sortable=True,
                                  useAlternateBackColors=False, cellEditMode=ObjectListView.CELLEDIT_DOUBLECLICK)
        self.olv.SetColumns([
            ColumnDefn(title="Parameter", valueGetter="parameter", isSpaceFilling=True, isEditable=False),
            ColumnDefn(title="Value", valueGetter="value", isSpaceFilling=True)
        ])

        get_button = wx.Button(self, label="Print objects")

        top_sizer = wx.BoxSizer(wx.VERTICAL)  # Root sizer
        olv_sizer = wx.BoxSizer(wx.VERTICAL)  # For the ObjectListView
        button_sizer = wx.BoxSizer(wx.HORIZONTAL)

        olv_sizer.Add(self.olv, 1, wx.LEFT | wx.RIGHT | wx.EXPAND | wx.ALIGN_TOP, 5)
        button_sizer.Add(get_button, 0, wx.ALL | wx.ALIGN_LEFT, 5)

        top_sizer.Add(olv_sizer, 1, wx.ALL | wx.EXPAND, 5)
        top_sizer.Add(button_sizer, 0, wx.ALL | wx.EXPAND, 5)

        self.SetSizerAndFit(top_sizer)
        self.Bind(wx.EVT_BUTTON, handler=self.get_objects, source=get_button)

        self.olv.SetObjects(random_objects)

    def get_objects(self, event):
        for item in self.olv.GetObjects():
            print("Parameter: {param}".format(param=item['parameter']))
            print("Value: {val}".format(val=item['value']))


if __name__ == "__main__":
    wx_app = wx.App()
    frame = MainFrame()
    wx_app.MainLoop()

当用户编辑列表时，random_objects 中的值也会更新，因此如果您愿意，您实际上可以使用它来代替 self.olv.GetObjects()。
