Then put setupWidgets() before setupGame() and move the connection inside setupGame() and before your emit.<br><br> connect(this, SIGNAL( signalLoadTheme()), m_gameTheme, SLOT( slotLoadTheme() ));<br> emit signalLoadTheme();<br>

Actually, there was a 2 way problem. I tried both and both failed.<br><br>Because if setupWidgets() is called first then m_gameTheme is invalid and if setupGame() is first then
emit signalLoadTheme(); is invalid as connection is not made yet. So, though not crash in this case, the slot will not be called.<br><br>Thanks for help<br>Mahfuz<div><div></div><div class="h5"><br><br><div class="gmail_quote">

Hi,<br>Sorry for my typo.<br>you did not create your m_gameTheme before you make
connection to it, just put setupGame() before setupWidgets()* can fix your
problem. line23:24 in MainWindow.cpp<div><div></div><div><br><br><div class="gmail_quote">On Sun, Jul 12, 2009 at 10:35 AM, Zeng Huan <span dir="ltr"><<a href="mailto:zh.issac@gmail.com" target="_blank">zh.issac@gmail.com</a>></span> wrote:<br>
