Topenglpanel

TOpenGLPanel is a visual component found in the LazOpenGLContext package. It inherits from TCustomControl but is specialized to create an "OpenGL Context." In simple terms, while a standard TPanel draws buttons and text using the operating system’s standard drawing routines (GDI or Cairo), a TOpenGLPanel hands control of its pixel buffer over to the GPU (Graphics Processing Unit).

Developers sometimes encounter External:SIGSEGV exceptions if they try to call OpenGL functions before the panel has fully initialized its context. It is best practice to perform initializations in the OnCreate or OnShow events only after ensuring the context is active using methods like MakeCurrent .
