Having some issues with PostMessage(). Application crashes with complaint
about calling a pure virtual function; I think it's localized to the message
system because (1) the crash does not occur when the PostMessage(...) call is
commented, and (2) a breakpoint set on the recipient function never triggers.
Relevant code:
* The PostMessage(...) call: (yeah, I know, it's ugly)
PostMessage( (Panel *)(gViewPortInterface->FindPanelByName( PANEL_BASE )), new
KeyValues( "SetShowPanel", "panel", PANEL_CLASS ) );
* The message handler declared: (in the header file of recipient object)
MESSAGE_FUNC_CHARPTR( SetShowPanel, "SetShowPanel", panel );
* A section of relevant code from the implementation:
static char *m_szPanelNames[] = { PANEL_CLASS };
void CBaseMenu::SetShowPanel( const char *panel )
{
for ( int i = 0; i < sizeof( m_szPanelNames ); i++ ) {
if ( Q_strcmp( panel, m_szPanelNames[i] ) ) // No match
PostMessage( (Panel
*)(gViewPortInterface->FindPanelByName
(m_szPanelNames[i] )), new KeyValues( "SetShade", "state", 0 ) );
else
PostMessage( (Panel *)
(gViewPortInterface->FindPanelByName( m_szPanelNames[i] )), new KeyValues
( "SetShade", "state", 1 ) );
}
}
---------------
Please excuse the poor formatting. Any obvious problems with the code?
Thanks.
