[ Picked text/plain from multipart/alternative ]
1) Declare as a private variable for the class:
vgui::HFont m_hFont;
Be sure to set it to a font in the constructor, we set to trebuchet:
m_hFont = g_hFontTrebuchet24;
2) Declare as a private variable for the class:
wchar_t sIDString[256];
3) You're right, code could be cleaned by moving variable declaration out of
Paint method.
Good luck!
