在wxPython中显示图像的网格

问题描述:

我想在wxPython中显示图像的网格。我使用的是GridSizer创建一个网格,这是我加我staticbitmaps。但出于某种原因,我只能在网格中的第一个位置看到一个图像。我不知道我哪里出错了。这是我的代码和相应的输出。在wxPython中显示图像的网格

import wx

class CommunicationApp(wx.App): 
    """This is the class for the communication tool application. 
    """ 

    def __init__(self, config=None, redirect=False): 
     """Instantiates an application.

     wx.App.__init__(self, redirect=redirect) 
     self.cfg = config

     self.grid.Fit(self) 

     # set to full screen. 
     # self.ShowFullScreen(not self.IsFullScreen(), 0) 


class CommuniationPanel(wx.Panel):

    def __init__(self, parent, pid, config):

     # CALLBACK BINDINGS 
     # Bind keyboard events. 
     self.Bind(wx.EVT_KEY_UP, self.on_key_up) 

    def on_key_up(self, evt): 
     """Handles Key UP events. 
     """ 
     code = evt.GetKeyCode() 
     print code, wx.WXK_ESCAPE 
     if code == wx.WXK_ESCAPE: 
      sys.exit(0) 


def main(): 
    app = CommunicationApp() 
    app.MainLoop() 


if __name__ == '__main__': 
    main() 

这里是输出。 enter image description here

我想看到(或预期看到的)是3X4不同图像的网格。

我的代码有什么问题?我该如何解决它?

我还没有试过运行的代码,但也许你忘了打电话'SetSizer '? 'self.panel.SetSizer(self.grid)' – GP89

@ GP89我知道这很简单但很关键,我错过了。有效!感谢您的帮助。 – siva82kb

没问题。我将发布它作为答案,以防将来帮助其他人 – GP89

你似乎忘记设置分级机为您的面板

尝试把这个在框架的__init__

self.panel.SetSizer(self.grid)
