wxpython自定义下拉列表框

自定义wxpython下拉列表框,支持修改边框颜色,按钮图标的动态变换

原理同前两片文章一样,使用了两个wx.staticText做边框,一个文本框来显示下拉列表的数据,和一个图片按钮,实现下拉的标志,和一个自带的列表框,

影藏该列表框,不要原来的样式,这里只需要使用它的展示列表的数据功能

自定义列表框的代码:

class MyComBox:
    """自定义下拉列表框"""
    def __init__(self,parent,pos,size=(200,35),choices=[],readOnly=False,borderColor='#EAEAEA',borderSize=1):
        self.defaultfontSize = 10
        self.defaultBorderColor = '#EAEAEA'
        self.defaultFontColor = 'black'

        self.textCtrl,self.combox,self.background,self.arrow_button = self.__CreateComBox(parent,pos,size,
                                                                                          choices,readOnly,borderColor,borderSize)
    def __CreateComBox(self,parent,pos,size,list,readOnly,borderColor,borderSize):
        #创建边框
        border = wx.StaticText(parent,-1,"",pos=pos,size=size)
        border.SetBackgroundColour(borderColor)
        bg = wx.StaticText(border,-1,"",size=((size[0]-borderSize*2),(size[1]-borderSize*2)),pos=(borderSize,borderSize))
        style = wx.TE_READONLY | wx.NO_BORDER

        #创建数据展示框
        self.textCtrl = wx.TextCtrl(bg,-1,size=((size[0]-30),(self.defaultfontSize*2)),
                                    pos=(5,(size[1]-2*self.defaultfontSize-borderSize*2)/2),style= style)
        self.textCtrl.SetBackgroundColour('white')
        #点击文本框显示数据
        if not readOnly:
            self.textCtrl.Bind(wx.EVT_LEFT_DOWN,self.__OnClick)

        #创建下拉点击按钮
        bmp = wx.Image("xia.jpg",wx.BITMAP_TYPE_ANY).ConvertToBitmap()
        arrow_button = wx.BitmapButton(bg,-1,bmp,size = (20,size[1]),pos=(size[0]-22,0),style =wx.NO_BORDER)

        #构建列表框,展示列表的数据
        self.chooseBox = wx.ComboBox(parent,-1,value="",size=(size[0],-1),pos = (pos[0],pos[1]+10),choices=list,style=wx.TE_READONLY)
        self.chooseBox.Hide()
        self.chooseBox.Bind(wx.EVT_COMBOBOX_CLOSEUP,self.__GetValue)

        #设置显示下列列表按钮
        arrow_button.SetBackgroundColour('white')
        font = wx.Font(self.defaultfontSize,wx.DEFAULT,wx.NORMAL,wx.NORMAL,False,'微软雅黑')
        self.textCtrl.SetFont(font)

        #设置只读情况的样式
        if readOnly:
            bg.SetBackgroundColour('rgb(240,240,240)')
            self.textCtrl.SetBackgroundColour('rgb(240,240,240)')
            arrow_button.SetBackgroundColour('rgb(240,240,240)')
        else:
          #  bg.SetBackgroundColour(self.textCtrl.GetBackgroundColour())
            arrow_button.Bind(wx.EVT_BUTTON,self.__OnClick)

        return self.textCtrl,self.chooseBox,border,arrow_button

    def __GetValue(self,event):
        if self.chooseBox.GetValue()!='':
            self.textCtrl.SetValue(self.chooseBox.GetValue())
            self.chooseBox.Hide()
            bmp = wx.Image("xia.jpg",wx.BITMAP_TYPE_ANY).ConvertToBitmap()
            self.arrow_button.SetBitmap(bmp)
        if self.chooseBox.GetValue()!='请选择':
            self.textCtrl.SetForegroundColour(self.defaultFontColor)


    def __OnClick(self,event):
        self.chooseBox.Show()
        self.chooseBox.Popup()
        bmp = wx.Image("shang.jpg", wx.BITMAP_TYPE_ANY).ConvertToBitmap()
        self.arrow_button.SetBitmap(bmp)

图片 ,这个需要下载下去,或者自己找漂亮的图片

测试代码:

# coding:utf-8
import wx

from wxpython import Mywxpython

app = wx.App()
frame = wx.Frame(None, title="Gui Test Editor", pos=(1000, 200), size=(500, 400))

panel = wx.Panel(frame)
panel.SetBackgroundColour('white')
# path_text = wx.TextCtrl(panel, size=(260, 36))
#
# my_text = Mywxpython.MyText(panel,pos=(10, 50),size=(260,36))
# my_text1 = Mywxpython.MyText(panel,pos=(10, 100),size=(260,36),readOnly=True)
# my_text.SetBorderColor('red')
list = ['1','2','3','4']
#wx.ComboBox(panel,-1,value="",size=(80,-1),pos = (100,110),choices=list,style=wx.TE_READONLY)

#my_button = Mywxpython.MyButton(panel,title="点我",pos=(10, 150))
combox = Mywxpython.MyComBox(panel,choices=['1','2','3','4'],pos=(10, 150))
#combox .SetValue("请选择")
frame.Show()
app.MainLoop()

结果图:

按钮又有点丑,需要自己定义,搞两个好看得图标,
