wxPython常用控件--wx.Grid,wx.ListBox,wx.ListCtrl,wx.TreeCtrl

wxPython各种控件用法官方手册 ： http://xoomer.virgilio.it/infinity77/wxPython/widgets.html

（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 StudentInfoGridTable

gridDatas = [
    [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
