I suspected it might be an old bug, but I’m restricted to the IUP and Lua versions associated with the software for which I’m writing plugins – at least I have a workaround which might help others who encounter the same issue.

See attached. I suspect this could be an old bug already fixed in previous versions. IUP 3.11.2 has more than 4 years now... Here is the output: D:\tecgraf\iup\bin\Win64\Lua51>lua5.1 \Downloads\close_show.lua SHOW_CB state=0 CLOSE_CB SHOW_CB state=4 destroy Best, Scuri Em qui, 18 de abr de 2019 às 13:53, <helen.wri...@atiras.com <mailto:helen.wri...@atiras.com> > escreveu: I have a dialog with both close_cb and show_cb defined. Environment is Windows 10, Lua 5.1, IUP 3.11.2 (I can’t upgrade). When the Dialog is closed using the Close Window X, the sequence of events is: close_cb show_cb (with state = 4) The last line dlg:destroy() is never executed so it appears the dialog is not destroyed although it is no longer visible. Removing the show_cb callback allows close_cb to work as it should. What am I doing wrong? ==========Sample code below ================== require( "iuplua" ) vbox = iup.vbox { iup.label {title="Label"}, iup.button { title="Test" } } dlg = iup.dialog{vbox; title="Dialog"} dlg.show_cb = function(self, state) if state == iup.SHOW then print(state) –content of the function is callback to the bug; it just has to exist end end dlg.close_cb = function() return iup.CLOSE end dlg:show() if (iup.MainLoopLevel()==0) then iup.MainLoop() end dlg:destroy() _______________________________________________ Iup-users mailing list Iup-users@lists.sourceforge.net <mailto:Iup-users@lists.sourceforge.net> https://lists.sourceforge.net/lists/listinfo/iup-users
