gtkGLArea GtkGLArea* gtkGLArea;: the main Gtk struct
getGLAreaStruct GtkGLArea* getGLAreaStruct(): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
setStruct void setStruct(GObject* obj): Undocumented in source. Be warned that the author may not have intended to support it.
getType GType getType()
attachBuffers void attachBuffers(): Ensures that the @area framebuffer object is made the current draw and read target, and that all the required buffers for the @area are created and bound to the frambuffer.
getAutoRender bool getAutoRender(): Returns whether the area is in auto render mode or not.
getContext GLContext getContext(): Retrieves the #GdkGLContext used by @area.
getError ErrorG getError(): Gets the current error set on the @area.
getHasAlpha bool getHasAlpha(): Returns whether the area has an alpha component.
getHasDepthBuffer bool getHasDepthBuffer(): Returns whether the area has a depth buffer.
getHasStencilBuffer bool getHasStencilBuffer(): Returns whether the area has a stencil buffer.
getRequiredVersion void getRequiredVersion(int major, int minor): Retrieves the required version of OpenGL set using gtk_gl_area_set_required_version().
getUseEs bool getUseEs(): Retrieves the value set by gtk_gl_area_set_use_es().
makeCurrent void makeCurrent(): Ensures that the #GdkGLContext used by @area is associated with the #GtkGLArea.
queueRender void queueRender(): Marks the currently rendered data (if any) as invalid, and queues a redraw of the widget, ensuring that the #GtkGLArea::render signal is emitted during the draw.
setAutoRender void setAutoRender(bool autoRender): If @auto_render is %TRUE the #GtkGLArea::render signal will be emitted every time the widget draws. This is the default and is useful if drawing the widget is faster.
setError void setError(ErrorG error): Sets an error on the area which will be shown instead of the GL rendering. This is useful in the #GtkGLArea::create-context signal if GL context creation fails.
setHasAlpha void setHasAlpha(bool hasAlpha): If @has_alpha is %TRUE the buffer allocated by the widget will have an alpha channel component, and when rendering to the window the result will be composited over whatever is below the widget.
setHasDepthBuffer void setHasDepthBuffer(bool hasDepthBuffer): If @has_depth_buffer is %TRUE the widget will allocate and enable a depth buffer for the target framebuffer. Otherwise there will be none.
setHasStencilBuffer void setHasStencilBuffer(bool hasStencilBuffer): If @has_stencil_buffer is %TRUE the widget will allocate and enable a stencil buffer for the target framebuffer. Otherwise there will be none.
setRequiredVersion void setRequiredVersion(int major, int minor): Sets the required version of OpenGL to be used when creating the context for the widget.
setUseEs void setUseEs(bool useEs): Sets whether the @area should create an OpenGL or an OpenGL ES context.
connectedSignals int[string] connectedSignals;: Undocumented in source.
onCreateContextListeners GLContext delegate(GLArea)[] onCreateContextListeners;: Undocumented in source.
addOnCreateContext void addOnCreateContext(GLContext delegate(GLArea) dlg, ConnectFlags connectFlags): The ::create-context signal is emitted when the widget is being realized, and allows you to override how the GL context is created. This is useful when you want to reuse an existing GL context, or if you want to try creating different kinds of GL options.
callBackCreateContext GdkGLContext* callBackCreateContext(GtkGLArea* glareaStruct, GLArea _glarea): Undocumented in source. Be warned that the author may not have intended to support it.
onRenderListeners bool delegate(GLContext, GLArea)[] onRenderListeners;: Undocumented in source.
addOnRender void addOnRender(bool delegate(GLContext, GLArea) dlg, ConnectFlags connectFlags): The ::render signal is emitted every time the contents of the #GtkGLArea should be redrawn.
callBackRender int callBackRender(GtkGLArea* glareaStruct, GdkGLContext* context, GLArea _glarea): Undocumented in source. Be warned that the author may not have intended to support it.
onResizeListeners void delegate(int, int, GLArea)[] onResizeListeners;: Undocumented in source.
addOnResize void addOnResize(void delegate(int, int, GLArea) dlg, ConnectFlags connectFlags): The ::resize signal is emitted once when the widget is realized, and then each time the widget is changed while realized. This is useful in order to keep GL state up to date with the widget size, like for instance camera properties which may depend on the width/height ratio.
callBackResize void callBackResize(GtkGLArea* glareaStruct, int width, int height, GLArea _glarea): Undocumented in source. Be warned that the author may not have intended to support it.
