    <p>I am trying to provide a custom button class that needs a hover for it to work properly. I am therefore using StaticBitmap and extending it. But I am finding differences between Windows and Linux using the same exact code between both. The following small simple example doesn't work properly in Linux, but works fine in Windows:</p> <pre><code>import wx class MyForm(wx.Frame): def __init__(self): wx.Frame.__init__(self, None, wx.ID_ANY, "Test") panel = wx.Panel(self, wx.ID_ANY, size=(200,100)) panel.SetBackgroundColour("Black") # create a normal bitmap button bitmap = wx.Bitmap("images/power.png", wx.BITMAP_TYPE_ANY) self.image1 = wx.StaticBitmap(panel, bitmap=bitmap, size=bitmap.GetSize()) sizer = wx.BoxSizer(wx.VERTICAL) sizer.Add(self.image1) panel.SetSizer(sizer) # This works on Windows, but not on Linux #self.image1.Bind(wx.EVT_ENTER_WINDOW, self.OnHover) #self.image1.Bind(wx.EVT_LEAVE_WINDOW, self.OnLeaveHover) # This (used by itself) gets events for both Linux/Win, but # doesn't find e.Entering() or e.Leaving() on Linux! self.image1.Bind(wx.EVT_MOUSE_EVENTS, self.OnMouseEvents) def OnHover(self, e): print "Hover" def OnLeaveHover(self,e): print "Leaving Hover" def OnMouseEvents(self,e): print "Mouse event" #print dir(e) if e.Entering(): print "Hover" elif e.Leaving(): print "Leaving Hover" else: e.Skip() if __name__ == "__main__": app = wx.App(False) frame = MyForm() frame.Show() app.MainLoop() </code></pre> <p>Is this a known issue? Is there some other way to bind the event to get the mouseover/hover operation to work properly in Linux?</p> <p>Also, no forms of <code>self.Bind()</code> work here on Linux or Windows. Why? i.e.:</p> <pre><code>self.Bind(wx.EVT_ENTER_WINDOW, self.OnHover, self.image1) self.Bind(wx.EVT_LEAVE_WINDOW, self.OnLeaveHover, self.image1) </code></pre>

    1. COThe second question about self.Bind() not working for either Linux or Windows is explained in "wxPython in Action" book. Enter/Leaving events cannot be bound to the frame. So scratch that. The bigger question is why Entering()/Leaving() is not working on Linux.

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.
