Question

我在Python 2.7上使用wxPython。我想帮助创建一个带位图图像的按钮。

我正在使用此视频https://www.youtube.com/watch?v=Y7f0a7xbWHI，然后我按照代码输入了

    def __init__(self,parent,id):
        wx.Frame.__init__(self,parent,id,'Frame aka window',size=(300,200))
        panel=wx.Panel(self)

        pic=wx.Image("back.bmp", wx.BITMAP_TYPE_BMP).ConvertToBitmap()
        self.button=wx.BitmapButton(panel, -1, pic, pos=(10,10))
        self.Bind(wx.EVT_BUTTON, self.doMe, self.button)
        self.button.SetDefault()

    def doMe(self, event):
        self.Destroy

创建带图像的按钮。我收到一条错误，指出无效图片。我将位图图像保存在我正在使用的.py文件的文件夹中。我觉得我把图像保存在错误的地方？先感谢您。

我收到的错误

Traceback (most recent call last):
  File "C:\Python27\FrameWindow.py", line 81, in <module>
    frame=bucky(parent=None,id=-1)
  File "C:\Python27\FrameWindow.py", line 17, in __init__
     pic=wx.Image("back.bmp", wx.BITMAP_TYPE_BMP).ConvertToBitmap()
  File "C:\Python27\lib\site-packages\wx\core.py", line 708, in _Image_ConvertToBitmap
    bmp = wx.Bitmap(self, depth)
wxAssertionError: C++ assertion "image.IsOk()" failed at ..\..\src  \msw\bitmap.cpp(922) in wxBitmap::CreateFromImage(): invalid image

Answer 1

使用wx.BITMAP_TYPE_ANY而不是wx.BITMAP_TYPE_BMP它是否需要猜测它是否真的是BMP 或直接使用wx.Bitmap()。

import wx

class MainFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self,None,-1,'Frame aka window',size=(300,200))
        panel=wx.Panel(self)
        #
        # Use wx.BITMAP_TYPE_ANY rather than wx.BITMAP_TYPE_BMP
        #
        #pic=wx.Image("Discord.bmp", wx.BITMAP_TYPE_ANY).ConvertToBitmap()
        #
        # or use wx.Bitmap()
        pic = wx.Bitmap("Discord.bmp", wx.BITMAP_TYPE_ANY)
        #
        self.button=wx.BitmapButton(panel, -1, pic, pos=(10,10))
        self.Bind(wx.EVT_BUTTON, self.doMe, self.button)
        self.Show()

    def doMe(self, event):
        self.Destroy()

if __name__ == "__main__":
      app = wx.App()
      frame = MainFrame()
      app.MainLoop()

原则上，您应该使用完整路径名命名您的图像。如果您有许多图像，那么在您使用它们时，请为您的图像名称设置一个图像目录并join该目录名称，这将再次为您提供完整路径（/home/images/back_button.bmp）

我通过添加

来实现它

"locale = wx.Locale(wx.LANGUAGE_ENGLISH)"

下

class MainFrame(wx.Frame):
    def __init__(self):

现在我没有收到错误消息，它按预期运行。我收到的这个问题的错误代码是：

Traceback (most recent call last):
   File "C:\Python27\panel test.py", line 21, in <module>
      frame = MainFrame()
   File "C:\Python27\panel test.py", line 11, in __init__
      pic = wx.Bitmap("back.bmp", wx.BITMAP_TYPE_ANY)
 wxAssertionError: C++ assertion "strcmp(setlocale(LC_ALL, NULL), "C") == 0" failed at ..\..\src\common\intl.cpp(1579) in wxLocale::GetInfo(): You probably called setlocale() directly instead of using wxLocale and now there is a mismatch between C/C++ and Windows locale.
 Things are going to break, please only change locale by creating wxLocale objects to avoid this!

我的主要问题给出的错误是由Rolf by Saxony给出的代码解决的。
