（12）表格， wx.grid.Grid，构造函数：
自定义的Grdi控件：
xGridTable.py
#coding=utf-8
import wx.grid as grid
class StudentInfoGridTable(grid.PyGridTableBase):
def __init__(self, datas):
grid.PyGridTableBase.__init__(self)
self.datas = datas
self.colLabels = [u'试卷名', u'制卷人', u'制卷人账号', u'考试成绩', u'测试开始时间', u'测试结束时间', u'测试时长']
self.odd = grid.GridCellAttr()
self.odd.SetReadOnly(True)
self.odd.SetBackgroundColour('yellow')
self.even = grid.GridCellAttr()
self.even.SetReadOnly(True)
pass
def GetAttr(self, row, col, kind):
attr = [self.even, self.odd][row % 2]
attr.IncRef()
return attr
def GetNumberRows(self):
return len(self.datas)
def GetNumberCols(self):
return len(self.colLabels)
def GetColLabelValue(self, col):
return self.colLabels[col]
def GetRowLabelValue(self, row):
return str(row)
def GetValue(self, row, col):
return self.datas[row][col]
在需要使用该控件的时候，实例化：
from xGridTable import StudentInfoGridTablegridDatas = [
[u'大仲马', u'男', u'WUST', u'中文', u'研三'],
[u'牛顿', u'男', u'HUST', u'物理', u'博一'],
[u'爱因斯坦', u'男', u'HUST', u'物理', u'研一'],
[u'居里夫人', u'女', u'WUST', u'化学', u'研一'],
]
self.gridTable = wx.grid.Grid(self, -1, pos=(5, 5), size=(600, 400), style=wx.WANTS_CHARS)
self.infoTable = StudentInfoGridTable(gridDatas)
self.gridTable.SetTable(self.infoTable, True)效果：
（13）简单的列表，wx.ListBox，构造函数：
"""
__init__(self, Window parent, int id=-1, Point pos=DefaultPosition,
Size size=DefaultSize, wxArrayString choices=wxPyEmptyStringArray,
long style=0, Validator validator=DefaultValidator,
String name=ListBoxNameStr) -> ListBox
"""panel = wx.Panel(self)
self.textFont = wx.Font(11, wx.DEFAULT, wx.NORMAL, wx.NORMAL, False)
listDatas = [u'ListBox是简单的列表', u'TreeCtrl是树状文件目录机构', u'ListCtrl复杂的列表',
u'RadioButton是单选项', u'CheckBox为多选项', u'StaticText显示静态文本',]
self.listBox = wx.ListBox(panel, -1, pos=(10, 10), size=(300, 120), choices=listDatas, style=wx.LB_SINGLE)
self.listBox.SetFont(self.textFont)
self.Bind(wx.EVT_LISTBOX, self.listCtrlSelectFunc, self.listBox)效果：
ListBox的事件监听：
def listCtrlSelectFunc(self, event): indexSelected = event.GetEventObject().GetSelection() print '选中Item的下标：', indexSelected pass点击效果：
（14）复杂列表，wx.ListCtrl，自定义的列表
xListCtrl.py
#coding=utf-8
import wx
class CourseListCtrl(wx.ListCtrl):
def __init__(self, parent, subDatas, size, id=-1, pos=(0, 0), style=wx.LC_SMALL_ICON):
wx.ListCtrl.__init__(self, parent, id, pos, size, style)
self.subDatas = subDatas
self.InitUI()
pass
def InitUI(self):
il = wx.ImageList(45, 45, True)
logoBmp = wx.Bitmap(r"D:\book_icon.png", wx.BITMAP_TYPE_PNG)
il.Add(logoBmp)
self.AssignImageList(il, wx.IMAGE_LIST_SMALL)
self.ShowListDatas(self.subDatas)
pass
def ShowListDatas(self, datas):
self.subDatas = datas
for index in range(len(self.subDatas)):
subject = self.subDatas[index]
content = u"科目：{0} 科目介绍：{1}".format(subject.get('name', ''), subject.get('intro', ''))
self.InsertImageStringItem(index, content, 0)
def refreshDataShow(self, newDatas):
self.datas = newDatas
self.DeleteAllItems()
self.ShowListDatas(self.datas)
self.Refresh()在使用ListCtrl的时候，导入并实例化：
from xListCtrl import CourseListCtrl
courseNames = [u'大学物理', u'计算机技术', u'微积分', u'电力电子']
courseDatas = []
for index in range(len(courseNames)):
obj = {}
obj['name'] = courseNames[index]
obj['intro'] = courseNames[index]+u'的简介......'
courseDatas.append(obj)
self.textFont = wx.Font(12, wx.DEFAULT, wx.NORMAL, wx.NORMAL, False)
self.courseListCtrl = CourseListCtrl(self, courseDatas, size=(300, 300), pos=(10, 10))
self.courseListCtrl.SetFont(self.textFont)
self.courseListCtrl.SetBackgroundColour('#ffffff')
self.Bind(wx.EVT_LIST_ITEM_SELECTED, self.courseListSelectFunc, self.courseListCtrl)效果：
ListCtrl事件监听：
def courseListSelectFunc(self, event):
index = event.GetIndex()
print u'选中的Item的下标:', index
pass
（15）树状文件结构，wx.TreeCtrl，自定义的树状图：
xTreeCtrl.py
#coding=utf-8 import wx import wx.gizmos as gizmos cityNames = { "Beijing": u"北京", "Wuhan": u"武汉", "Shanghai": u"上海", } def GetCityChinexeName(id): return cityNames.get(id, '') class CollegeTreeListCtrl(wx.gizmos.TreeListCtrl): def __init__(self, parent=None, id=-1, pos=(0,0), size=wx.DefaultSize, style=wx.TR_DEFAULT_STYLE|wx.TR_FULL_ROW_HIGHLIGHT): wx.gizmos.TreeListCtrl.__init__(self, parent, id, pos, size, style) self.root = None self.InitUI() pass def InitUI(self): self.il = wx.ImageList(16, 16, True) self.il.Add(wx.ArtProvider_GetBitmap(wx.ART_FOLDER, wx.ART_OTHER, (16, 16))) self.il.Add(wx.ArtProvider_GetBitmap(wx.ART_FILE_OPEN, wx.ART_OTHER, (16, 16))) self.il.Add(wx.ArtProvider_GetBitmap(wx.ART_NORMAL_FILE, wx.ART_OTHER, (16, 16))) self.SetImageList(self.il) self.AddColumn(u'学校名称') self.AddColumn(u'是否985') self.AddColumn(u'学校类型') pass def ShowItems(self, datas): self.SetColumnWidth(0, 150) self.SetColumnWidth(1, 40) self.SetColumnWidth(2, 47) self.root = self.AddRoot(u'中国大学') self.SetItemText(self.root, "", 1) self.SetItemText(self.root, "", 2) # 填充整个树 cityIDs = datas.keys() for cityID in cityIDs: child = self.AppendItem(self.root, cityID) lastList = datas.get(cityID, []) childTitle = GetCityChinexeName(cityID)+u" (共"+str(len(lastList))+u"所大学)" self.SetItemText(child, childTitle, 0) self.SetItemText(child, "", 1) self.SetItemText(child, "", 2) self.SetItemImage(child, 0, which=wx.TreeItemIcon_Normal) self.SetItemImage(child, 1, which=wx.TreeItemIcon_Expanded) for index in range(len(lastList)): college = lastList[index] # TreeItemData是每一个ChildItem的唯一标示 # 以便在点击事件中获得点击项的位置信息 data = wx.TreeItemData(cityID+"|"+str(index)) last = self.AppendItem(child, str(index), data=data) self.SetItemText(last, college.get('collegeName', ''), 0) self.SetItemText(last, college.get('if_985_type', ''), 1) self.SetItemText(last, college.get('collegeType', ''), 2) self.SetItemImage(last, 0, which=wx.TreeItemIcon_Normal) self.SetItemImage(last, 1, which=wx.TreeItemIcon_Expanded) self.Expand(self.root) pass def refreshDataShow(self, newDatas): if self.root != None: self.DeleteAllItems() if newDatas != None: self.ShowItems(newDatas) def DeleteSubjectItem(self, treeItemId): self.Delete(treeItemId) self.Refresh() pass
在需要显示数据的地方导入并实例化：
from xTreeCtrl import CollegeTreeListCtrl
self.treeListCtrl = CollegeTreeListCtrl(parent=self, pos=(-1, 39), size=(300, 300))
self.Bind(wx.EVT_TREE_SEL_CHANGED, self.OnTreeListCtrlClickFunc, self.treeListCtrl)
self.colleges = {
u'Beijing': [
{'collegeName': u'北京大学', 'if_985_type':u'是', 'collegeType':u'综合类'},
{'collegeName': u'清华大学', 'if_985_type': u'是', 'collegeType': u'理工类'},
{'collegeName': u'北京邮电大学', 'if_985_type': u'否', 'collegeType': u'理工类'}],
u'Wuhan':[
{'collegeName': u'武汉大学', 'if_985_type': u'是', 'collegeType': u'综合类'},
{'collegeName': u'华中科技大学', 'if_985_type': u'是', 'collegeType': u'理工类'}
],
u'Shanghai': [
{'collegeName': u'上海交通大学', 'if_985_type': u'是', 'collegeType': u'理工类'},
{'collegeName': u'复旦大学', 'if_985_type': u'是', 'collegeType': u'综合类'},
{'collegeName': u'同济大学', 'if_985_type': u'是', 'collegeType': u'综合类'}
]
}
# TreeCtrl显示数据接口
self.treeListCtrl.refreshDataShow(self.colleges)
效果：
TreeCtrl的点击事件：
def OnTreeListCtrlClickFunc(self, event):
if self.treeListCtrl.GetItemData(event.GetItem()) != None:
# 当前选中的TreeItemId对象，方便进行删除等其他的操作
self.currentTreeItemId = event.GetItem()
cityName, collegeIndex = str(self.treeListCtrl.GetItemData(event.GetItem()).GetData()).split("|")
collegeObj = self.colleges.get(cityName, [])[int(collegeIndex)]
print '点击了：', cityName +u"的"+collegeObj.get('collegeName', '')
pass
