Constructor Details

#initialize(parent, vis, sharegroup, target = nil, selector = 0, opts = 0, x = 0, y = 0, width = 0, height = 0) ⇒ FXGLCanvas

Construct an OpenGL-capable canvas that shares its display list with another GL canvas. This canvas becomes a member of a display list share group. All members of the display list share group have to have the same visual.

# File 'rdoc-sources/FXGLCanvas.rb', line 9

def initialize(parent, vis, target=nil, selector=0, opts=0, x=0, y=0, width=0, height=0) # :yields: theGLCanvas
end

Instance Method Details

#context ⇒ Object

Return an integer handle to the underlying OpenGL context. On Unix/Linux systems, this is the GLX rendering context returned by a call to glXCreateContext(). On Microsoft Windows systems, it is the value returns by wglCreateContext().

# File 'rdoc-sources/FXGLCanvas.rb', line 30

def context; end

#current? ⇒ Boolean

Return true if this canvas’ context is the current context.

Returns:

• (Boolean)

# File 'rdoc-sources/FXGLCanvas.rb', line 39

def current? ; end

#makeCurrent ⇒ Object

Make OpenGL context current prior to performing OpenGL commands

# File 'rdoc-sources/FXGLCanvas.rb', line 33

def makeCurrent(); end

#makeNonCurrent ⇒ Object

Make OpenGL context non-current

# File 'rdoc-sources/FXGLCanvas.rb', line 36

def makeNonCurrent(); end

#shared? ⇒ Boolean

Return true if sharing display lists.

Returns:

• (Boolean)

# File 'rdoc-sources/FXGLCanvas.rb', line 22

def shared? ; end

#swapBuffers ⇒ Object

Swap front and back buffer

# File 'rdoc-sources/FXGLCanvas.rb', line 42
