Re: [Wxlua-users] Re: XRC can not load a panel

[Steve K. <ha...@ya...>]

did you hand-write the XRC ?
To me it looks like a wx problem; you could try to modify the 'xrc' 
sample to see if you can reproduce with wxWidgets directly.

the xrc is created using a rad tool (hatch), and looks no problem to me. I have read the code of wxLua binding as well no found no problem (actually just puch and pop things.
so I too highly suspect this is wxWidgets problem but since no one reported it so far in wxBugreport. I need to reporduced it using c++ to confirm

Update: yes it seems wxWidgets problem reproduced by c++ code. Actually in c++ I just need to load the frame and show it, it automatically show the panel child; so no one wants to load the panel anymore. but in wxLua it seems not.

XRC file is

<?xml version="1.0" encoding="UTF-8"?>
<resource version="2.3.0.1" xmlns="http://www.wxwidgets.org/wxxrc">
    <object class="wxFrame" name="ID_FRAME" subclass="t">
        <style>wxCAPTION|wxRESIZE_BORDER|wxSYSTEM_MENU|wxCLOSE_BOX</style>
        <size>400,300</size>
        <title>t</title>
        <object class="wxPanel" name="ID_PANEL">
            <style>wxSUNKEN_BORDER|wxTAB_TRAVERSAL</style>
            <object class="wxButton" name="ID_BUTTON">
                <label>Button</label>
            </object>
        </object>
    </object>
</resource>


Assuming this is a wx bug, I suggest you to use a sizer inside the frame 
wrapping the panel; maybe this will workaround the bug.
Nope it doesn work.

One thing is, in C++ I do not need to load the panel at all, show the frame is fine (it show the panel as well as all control on the panel; But in wxLua I can not, let me re-check this.

Sorry about long email :-)

I have file a bug report in wxWidgets page.

Cheers,
