A GLView widget allows for simple GL rendering in elementary environment. GLView hides all the complicated evas_gl details so that the user only has to deal with registering a few callback functions for rendering to a surface using OpenGL APIs.

This widget emits the following signals, besides the ones sent from Elm_GLView:

"focused" - when glview has received focus.
"unfocused" - when glview has lost focus.
"language,changed" - the program's language changed

Functions
Evas_Object *	elm_glview_add (Evas_Object *parent)

Enumeration Type Documentation

enum Elm_GLView_Mode

Selects the target surface properties.

An OR combination of Elm_GLView_Mode values should be passed to elm_glview_mode_set when setting up a GL widget. These flags will specify the properties of the rendering target surface; in particular, the mode can request the surface to support alpha, depth and stencil buffers.

Note:: ELM_GLVIEW_CLIENT_SIDE_ROTATION is a special value that indicates to EFL that the application will handle the view rotation when the device is rotated. This is needed only when the application requests direct rendering. Please refer to Rendering GL on Evas for more information about direct rendering.

Enumerator:

ELM_GLVIEW_ALPHA	Alpha channel enabled rendering mode
ELM_GLVIEW_DEPTH	Depth buffer enabled rendering mode (24 bits by default)
ELM_GLVIEW_STENCIL	Stencil buffer enabled rendering mode (8 bits by default)
ELM_GLVIEW_DIRECT	Request direct rendering, unless there must be a fallback
ELM_GLVIEW_CLIENT_SIDE_ROTATION	Client will handle GL view rotation if direct rendering is enabled
ELM_GLVIEW_DEPTH_8	Request min. 8 bits for the depth buffer
ELM_GLVIEW_DEPTH_16	Request min. 16 bits for the depth buffer
ELM_GLVIEW_DEPTH_24	Request min. 24 bits for the depth buffer (default)
ELM_GLVIEW_DEPTH_32	Request min. 32 bits for the depth buffer
ELM_GLVIEW_STENCIL_1	Request min. 1 bits for the stencil buffer
ELM_GLVIEW_STENCIL_2	Request min. 2 bits for the stencil buffer
ELM_GLVIEW_STENCIL_4	Request min. 4 bits for the stencil buffer
ELM_GLVIEW_STENCIL_8	Request min. 8 bits for the stencil buffer (default)
ELM_GLVIEW_STENCIL_16	Request min. 16 bits for the stencil buffer
ELM_GLVIEW_MULTISAMPLE_LOW	MSAA with minimum number of samples
ELM_GLVIEW_MULTISAMPLE_MED	MSAA with half the number of maximum samples
ELM_GLVIEW_MULTISAMPLE_HIGH	MSAA with maximum number of samples

enum Elm_GLView_Render_Policy

Defines a policy for gl rendering.

The rendering policy tells glview where to run the gl rendering code. ELM_GLVIEW_RENDER_POLICY_ON_DEMAND tells glview to call the rendering calls on demand, which means that the rendering code gets called only when it is visible.

Note:: Default is ELM_GLVIEW_RENDER_POLICY_ON_DEMAND

Enumerator:

ELM_GLVIEW_RENDER_POLICY_ON_DEMAND	Render only when there is a need for redrawing
ELM_GLVIEW_RENDER_POLICY_ALWAYS	Render always even when it is not visible

enum Elm_GLView_Resize_Policy

Defines a policy for the glview resizing.

The resizing policy tells glview what to do with the underlying surface when resize happens. ELM_GLVIEW_RESIZE_POLICY_RECREATE will destroy the current surface and recreate the surface to the new size. ELM_GLVIEW_RESIZE_POLICY_SCALE will instead keep the current surface but only display the result at the desired size scaled.

Note:: Default is ELM_GLVIEW_RESIZE_POLICY_RECREATE

Enumerator:

ELM_GLVIEW_RESIZE_POLICY_RECREATE	Resize the internal surface along with the image
ELM_GLVIEW_RESIZE_POLICY_SCALE	Only resize the internal image and not the surface
