Unknown style flag wxVSCROLL -- error

wxPython Users
1

To separate the view and control I started using xrc.

ERROR: Unknown style flag wxVSCROLL

self.m_grid = wx.grid.Grid( self, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, wx.HSCROLL|wx.VSCROLL )

The above code works fine (If I don’t use XRC)

wxHSCROLL|wxVSCROLL

While loading this object using XRC, its showing that error

------- I’m using
Python 2.7.5
wxPython 2.8.12

Can you pl help me in solving this.

Those styles are added for all window types in XRC so I'm not sure what might be causing the problem. However, you really shouldn't need them with wxGrid because scrolling will automatically be enabled when needed to be able to display all the cells.

Thanks Robin.

Can you recommend a site or material with information on XRC in more detail (like the demo in wxPython which is really helpful)

I checked the wiki too. They have only one or two examples.

I wrote a tutorial on XRC a while ago that contains several links to other resources. It might help you a little: wxPython: An Introduction to XRC - Mouse Vs Python

Oh, I wrote this too: wxPython: An XRCed Tutorial - Mouse Vs Python

Hope that helps!

Thanks Mike.

Do you have an example on wxGrid (general table) with XRC + XRCed?

Well, theoretically, the attached should work. However, when I try to pull the XRCCTRL is somehow changing my wx.Grid into a ScrolledWindow. Maybe Robin or someone else can see what’s happening. The XRC code looks right, but I’m getting the wrong widget.

I, too, am facing the same problem with the wxGrid changing to
ScrolledWindow while loading from xrc.

I took a look in the wx archive, and this one’s been posed before, with a solution from Robin:

*You need to import wx.grid in your python code. When you do that then
some internal data structures are updated with the type info for the
grid classes, and this info is used when figuring out how to convert a
C++ pointer to a Python object of the right typ for the XRCCTRL return
value. *

Mike, I tried it out on your example (inserted an import wx.grid after the import wx statement) and it worked like a champ.

Yeah, its working after that import statement. I somehow missed that post.

Thanks Edoc

Good catch. I missed that too. I’ll be posting a little article about this on my blog later today so it’s easier to find next time…
