Hi,
I got a strange behavior when creating a dialog from a coroutine, and
resuming the coroutine when a dialog button is clicked. It seems the
function called by the button click event is executed as if it was
called by the coroutine, while, unless I'm missing something obvious, it
should not. I've isolated the problem in a small application :
-- I overwrite print and assert functions to get messages in the console
window
local print = print -- don't want wxLua print function
local assert = function( cond, msg, ... )
if not cond then
print( "Assertion failed: "..msg )
print( debug.traceback() )
end
return cond, msg, ...
end
require( "wx" )
function callback()
print( "Button clicked" )
assert( coroutine.resume( co ) )
end
function createDialog()
dialog = wx.wxDialog( wx.NULL, wx.wxID_ANY, "Test dialog",
wx.wxDefaultPosition, wx.wxDefaultSize )
panel = wx.wxPanel( dialog, wx.wxID_ANY )
sizer = wx.wxBoxSizer( wx.wxHORIZONTAL )
button = wx.wxButton( panel, wx.wxID_ANY, "Test button" )
dialog:Connect( button:GetId(), wx.wxEVT_COMMAND_BUTTON_CLICKED,
callback )
sizer:Add( button )
panel:SetSizer( sizer )
sizer:SetSizeHints( dialog )
dialog:Show( true )
end
co = coroutine.create( function()
createDialog()
print( "Yield..." )
coroutine.yield()
print( "After yield" )
end )
assert( coroutine.resume( co ) )
wx.wxGetApp():MainLoop()
Here is the log I get :
Yield...
Button clicked
Assertion failed: cannot resume running coroutine
stack traceback:
test.lua:6: in function 'assert'
test.lua:15: in function <test.lua:13>
[C]: in function 'yield'
test.lua:36: in function <test.lua:33>
It seems very weird to me, that something is in the callstack above the
"yield" call... I've not looked into wxLua source code yet, don't know
if I'm doing something wrong or if there is some bug here.
Any help would be appreciated...
