    <p>I've isolated the cause of the problem to be the image, since the code seems to work with other png images with transparency. However, it doesn't seem to work with the one image I need it to. This would be of great help seeing as I'm trying to make a nice shaped window. </p> <p>The image:</p> <p><a href="http://i32.tinypic.com/f1xlj7.png" rel="nofollow noreferrer">alt text http://i32.tinypic.com/f1xlj7.png</a></p> <p>The code:</p> <pre><code>import wx class PictureWindow(wx.Frame): def __init__(self, parent, id, title, pic_location): # For PNGs. Must be PNG-8 for transparency... self.bmp = wx.Image(pic_location, wx.BITMAP_TYPE_PNG).ConvertToBitmap() framesize = (self.bmp.GetWidth(), self.bmp.GetHeight()) # Launch a frame the size of our image. Note the position and style stuff... # (Set pos to (-1, -1) to let the OS place it. # This style wx.FRAME_SHAPED is a frameless plain window. wx.Frame.__init__(self, parent, id, title, size=framesize, pos = (50, 50), style = wx.FRAME_SHAPED) r = wx.RegionFromBitmap(self.bmp) self.SetShape(r) # Define the panel and place the pic panel = wx.Panel(self, -1) self.mainPic = wx.StaticBitmap(panel, -1, self.bmp) # Set an icon for the window if we'd like #icon1 = wx.Icon("icon.ico", wx.BITMAP_TYPE_ICO) #self.SetIcon(icon1) self.Show() # The paint stuff is only necessary if doing a shaped window self.Bind(wx.EVT_PAINT, self.OnPaint) self.Main() def OnPaint(self, event): dc = wx.PaintDC(self) dc.DrawBitmap(self.bmp, 0, 0, True) def Main(self): sizer = wx.GridBagSizer() button = wx.Button(self,-1,label="Click me !") sizer.Add(button, (0,1)) # What pic are we opening? pic_location = r"C:\Users\user\Pictures\CPUBAR\A4.png" # PNG must be png-8 for transparency... app = wx.App(redirect=0) # the redirect parameter keeps stdout from opening a wx gui window PictureWindow(None, -1, 'Picture Viewer', pic_location) app.MainLoop() </code></pre> <p>This is in Windows 7, btw. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
