Question

我只知道如何在普通面板中显示图像。 如何在滚动面板中显示。图像可以改变。我在谷歌搜索过。但我无法在我的框架中获得合适的代码以下是我在普通面板中显示图像的代码

#!/usr/bin/env python

import numpy 
import sys, os
import wx
import wx.lib.scrolledpanel as scrolled
from PIL import Image



class  WinFrame(wx.Frame):
    def __init__(self, parent, title, width, height):
        super(WinFrame, self).__init__(parent, 
                                       title=title,
                                       size=(width, height))
        self.Panel = wx.Panel(self,size=(width/4,height),
                                  pos=(0,0),
                                  style=wx.BORDER)        

        self.imgPanel = wx.Panel(parent=self,
                                 size=(width, height),
                                 pos=(0,0),
                                 style=wx.BORDER)

        self.bitMap = wx.StaticBitmap(parent=self.imgPanel)

        img = Image.open('./image.jpg')
        img=img.resize([1280, 1280], Image.ANTIALIAS)

        wxImg = wx.EmptyImage(img.size[0], img.size[1])
        wxImg.SetData(img.tostring())
        wxImg = wxImg.ConvertToBitmap()
        self.bitMap.SetBitmap(wxImg)

        self.Centre()
        self.Show(True)        

    def __del__(self):
        super(WinFrame, self).__del__()

class myApp(wx.App):
    def __init__(self, width, height):
        super(myApp, self).__init__(0)

        self.width = width
        self.height = height

    def createFrame(self):
        self.frame = WinFrame(None, "show_img", self.width, self.height)
        self.SetTopWindow(self.frame)    

    def __del__(self):
        super(myApp, self).__del__()


def main():
    app = myApp(480, 480)
    app.createFrame()
    app.MainLoop()

if "__main__" == __name__ :
    main()

使用滚动面板。并添加静态位图。喜欢以下代码

#!/usr/bin/env python

import sys, os
import wx
import wx.lib.scrolledpanel as scrolled

class ImgPanel(scrolled.ScrolledPanel):
    def __init__(self, parent):
        super(ImgPanel, self).__init__(parent, 
                                       style = wx.SUNKEN_BORDER)

        self.bitmap=wx.StaticBitmap(parent=self)
        image = wx.Bitmap('image.jpg')
        self.bitmap.SetBitmap(image)

        self.imgSizer = wx.BoxSizer(wx.VERTICAL)        
        self.imgSizer.Add(self.bitmap, 1, wx.EXPAND)
        self.SetSizer(self.imgSizer)

        self.SetAutoLayout(1)
        self.SetupScrolling()    
        self.Bind(wx.EVT_PAINT, self.OnPaint)
        self.bitmap.Bind(wx.EVT_MOTION, self.OnMove)
        self.bitmap.Bind(wx.EVT_LEFT_DOWN, self.OnLeftDown)
        self.bitmap.Bind(wx.EVT_LEFT_UP, self.OnLeftUp)
        self.IsRectReady = False
        self.newRectPara=[0,0,0,0]

class  WinFrame(wx.Frame):
    def __init__(self, parent, title, width, height):
        super(WinFrame, self).__init__(parent, 
                                       title=title,
                                       size=(width, height))

        self.imgPanel = ImgPanel(self)
        self.frameSizer = wx.BoxSizer(wx.HORIZONTAL)        
        self.frameSizer.Add(self.imgPanel, 1, wx.EXPAND)        
        self.SetAutoLayout(True)
        self.SetSizer(self.frameSizer)
        self.Layout()      

        self.Centre()
        self.Show(True)        


class MyApp(wx.App):
    def __init__(self, width, height):
        super(MyApp, self).__init__(0)

        self.width = width
        self.height = height

    def createFrame(self):
        self.frame = WinFrame(None, "test", self.width, self.height)
        self.SetTopWindow(self.frame)    

def main():
    app = MyApp(640, 480)
    app.createFrame()
    app.MainLoop()

if "__main__" == __name__ :
    main()
