Dear all:
I have just encountered this kind of issue,using wxlua in Lua for
windows (LuaForWindows_v5.1.4-36).I extend class using the method
mentioned in "Extending classes" of
http://wxlua.sourceforge.net/docs/wxlua.html.
In the attatchment of file "veryminimal.wx.wlua",I wrote a coroutine
function in a button handler.
"""
function mainframe_on_button(self,event)
print("---outside coroutine")
print(self)
print(self.button)
print(self.textEntry)
local function test_co_func()
print("---inside coroutine")
print(self)
print(self.button)
print(self.textEntry)
end
self.co = coroutine.create(test_co_func)
local r,e = coroutine.resume(self.co)
if (r == false) then
print(r,e)
end
end
"""
And the output is:
"""
---outside coroutine
userdata: 016454F8 [wxFrame(01645138, 186)]
userdata: 016462F0 [wxButton(01646160, 109)]
userdata: 01645D98 [wxTextCtrl(01645BA0, 337)]
---inside coroutine
userdata: 016454F8 [wxFrame(01645138, 186)]
button
textEntry
"""
Why can not access the right value in coroutine ?
Thanks!
