wxLC_VIRTUAL not recognized by XmlResource

wxPython Users

Hi,

I am really getting into using XML resources for my current project, and I have found that creating a wxListCtrl with XRCED doe snot support the wxLC_VIRTUAL flag. I added it manually to the flags list, but it is not recognized by wxPython when you load the parent panel with wxXmlResource.LoadPanel().

I have searched a lot on Google and found nothing. I tried adding my own wxXmlResourceHandler but I can't get it to work. I can create the control manually, but if there is a way to add a style to a control or a workaround in the XML I would be very appreciative.

Thanks,
Mark.

Why don't you simply add the style to existing handler? (Done now in
both branches, thanks!)

OK - call me simple, but how do I do that? How do I get an instance of the existing wxListCtrlXmlHandler for a given XmlResource instance?

For what it is worth - I figured a way around this by doing the following:

    self.panel = self.panel_res.LoadPanel(self.frame, "CUSTOMER_PANEL")
    self.data_list = XRCCTRL(self.panel, "LISTCTRL_CUSTOMER_DATA")
    self.data_list.SetWindowStyleFlag(self.data_list.GetWindowStyleFlag()

wxLC_VIRTUAL)

It seems to work, but I think adding the style to the resource handler is better if you can give me a hint as to how ;o).

Thanks,
Mark.

You can't do it from outside, you must modify the handler's (C++)
code, which is what I did. I don't know how to workaround it in the
meantime till the next wxPy version is released, sorry.

Thanks for the help, Vaclav. I am not going to get into modifying the C++ code, and I seem to have found a workaround. Turns out, I am needing to use my own sql-aware subclass of a wxListCtrl anyway, so I am just using class="unknown" as a placeholder in the XRC and subbing in my class (with proper styles) using wxXmlResource.AttachUnknownControl(). It works fine

I am really liking the XRCed way of doing things. It makes my life a whole lot easier when it comes to sizers, and cleans up my code a lot!

Mark.
