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

It was not a problem when I connected signals and slots within the same class(I even don't included the moc file!).<br>
<br>This is what I have done to connect two different classes:<br>
<br>I have a signal declared in MainWindow(inheritx kxmlGuiWindow) class named signalLoadTheme() <br>and a slot in ThemeManager class(inherits QSvgRenderer) named slotLoadTheme(). <br><br>I created a instance of ThemeManager in MainWindow name m_gameTheme( ThemeManager* m_Theme)<br>
and connected them in MainWindow using:<br><br>
<p style="margin: 0px; text-indent: 0px;"><b>connect(this, SIGNAL( signalLoadTheme()), m_gameTheme, SLOT( slotLoadTheme() ));</b></p><p style="margin: 0px; text-indent: 0px;"><br></p><p style="margin: 0px; text-indent: 0px;">
I used Q_OBJECT in both of the classes at first (tried also including moc files).</p><p style="margin: 0px; text-indent: 0px;"><br></p><p style="margin: 0px; text-indent: 0px;">But, this is not working, my program is crashing.<br>
