Additional Definitions. + + As used herein, "this License" refers to version 3 of the GNU Lesser +General Public License, and the "GNU GPL" refers to version 3 of the GNU +General Public License. + + "The Library" refers to a covered work governed by this License, +other than an Application or a Combined Work as defined below. + + An "Application" is any work that makes use of an interface provided +by the Library, but which is not otherwise based on the Library. +Defining a subclass of a class defined by the Library is deemed a mode +of using an interface provided by the Library. + + A "Combined Work" is a work produced by combining or linking an +Application with the Library. The particular version of the Library +with which the Combined Work was made is also called the "Linked +Version". + + The "Minimal Corresponding Source" for a Combined Work means the +Corresponding Source for the Combined Work, excluding any source code +for portions of the Combined Work that, considered in isolation, are +based on the Application, and not on the Linked Version. + + The "Corresponding Application Code" for a Combined Work means the +object code and/or source code for the Application, including any data +and utility programs needed for reproducing the Combined Work from the +Application, but excluding the System Libraries of the Combined Work. + + 1. Exception to Section 3 of the GNU GPL. + + You may convey a covered work under sections 3 and 4 of this License +without being bound by section 3 of the GNU GPL. + + 2. Conveying Modified Versions. + + If you modify a copy of the Library, and, in your modifications, a +facility refers to a function or data to be supplied by an Application +that uses the facility (other than as an argument passed when the +facility is invoked), then you may convey a copy of the modified +version: + + a) under this License, provided that you make a good faith effort to + ensure that, in the event an Application does not supply the + function or data, the facility still operates, and performs + whatever part of its purpose remains meaningful, or + + b) under the GNU GPL, with none of the additional permissions of + this License applicable to that copy. + + 3. Object Code Incorporating Material from Library Header Files. + + The object code form of an Application may incorporate material from +a header file that is part of the Library. You may convey such object +code under terms of your choice, provided that, if the incorporated +material is not limited to numerical parameters, data structure +layouts and accessors, or small macros, inline functions and templates +(ten or fewer lines in length), you do both of the following: + + a) Give prominent notice with each copy of the object code that the + Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the object code with a copy of the GNU GPL and this license + document. + + 4. Combined Works. + + You may convey a Combined Work under terms of your choice that, +taken together, effectively do not restrict modification of the +portions of the Library contained in the Combined Work and reverse +engineering for debugging such modifications, if you also do each of +the following: + + a) Give prominent notice with each copy of the Combined Work that + the Library is used in it and that the Library and its use are + covered by this License. + + b) Accompany the Combined Work with a copy of the GNU GPL and this license + document. + + c) For a Combined Work that displays copyright notices during + execution, include the copyright notice for the Library among + these notices, as well as a reference directing the user to the + copies of the GNU GPL and this license document. + + d) Do one of the following: + + 0) Convey the Minimal Corresponding Source under the terms of this + License, and the Corresponding Application Code in a form + suitable for, and under terms that permit, the user to + recombine or relink the Application with a modified version of + the Linked Version to produce a modified Combined Work, in the + manner specified by section 6 of the GNU GPL for conveying + Corresponding Source. + + 1) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (a) uses at run time + a copy of the Library already present on the user's computer + system, and (b) will operate properly with a modified version + of the Library that is interface-compatible with the Linked + Version. + + e) Provide Installation Information, but only if you would otherwise + be required to provide such information under section 6 of the + GNU GPL, and only to the extent that such information is + necessary to install and execute a modified version of the + Combined Work produced by recombining or relinking the + Application with a modified version of the Linked Version. (If + you use option 4d0, the Installation Information must accompany + the Minimal Corresponding Source and Corresponding Application + Code. If you use option 4d1, you must provide the Installation + Information in the manner specified by section 6 of the GNU GPL + for conveying Corresponding Source.) + + 5. Combined Libraries. + + You may place library facilities that are a work based on the +Library side by side in a single library together with other library +facilities that are not Applications and are not covered by this +License, and convey such a combined library under terms of your +choice, if you do both of the following: + + a) Accompany the combined library with a copy of the same work based + on the Library, uncombined with any other library facilities, + conveyed under the terms of this License. + + b) Give prominent notice with the combined library that part of it + is a work based on the Library, and explaining where to find the + accompanying uncombined form of the same work. + + 6. Revised Versions of the GNU Lesser General Public License. + + The Free Software Foundation may publish revised and/or new versions +of the GNU Lesser General Public License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. + + Each version is given a distinguishing version number. If the +Library as you received it specifies that a certain numbered version +of the GNU Lesser General Public License "or any later version" +applies to it, you have the option of following the terms and +conditions either of that published version or of any later version +published by the Free Software Foundation. If the Library as you +received it does not specify a version number of the GNU Lesser +General Public License, you may choose any version of the GNU Lesser +General Public License ever published by the Free Software Foundation. + + If the Library as you received it specifies that a proxy can decide +whether future versions of the GNU Lesser General Public License shall +apply, that proxy's public statement of acceptance of any version is +permanent authorization for you to choose that version for the +Library. diff --git a/Setup.hs b/Setup.hs new file mode 100644 --- /dev/null +++ b/Setup.hs @@ -0,0 +1,2 @@ +import Distribution.Simple +main = defaultMain diff --git a/awesomium-glut.cabal b/awesomium-glut.cabal new file mode 100644 --- /dev/null +++ b/awesomium-glut.cabal @@ -0,0 +1,30 @@ + +Name: awesomium-glut +Version: 0.1.0.0 +Synopsis: Utilities for using Awesomium with GLUT. +License: LGPL-3 +License-File: LICENSE +Copyright: (c) 2012 Maksymilian Owsianny +Author: Maksymilian Owsianny +Maintainer: Maksymilian.Owsianny+AwesomiumGLUT@gmail.com +Bug-Reports: https://github.com/MaxOw/awesomium-glut/issues +Category: Graphics, Web +Build-Type: Simple +Stability: Experimental +Cabal-Version: >=1.8 + +Description: This package contains utilities for integrating + Awesomium with GLUT (Mainly functions for + marshalling input). + +Source-Repository head + Type: git + Location: https://github.com/MaxOw/awesomium-glut.git + +library + Exposed-Modules: Graphics.UI.Awesomium.GLUT + Build-Depends : awesomium-raw, awesomium + , base >= 3 && < 5 + , GLUT + Hs-Source-Dirs : src + diff --git a/src/Graphics/UI/Awesomium/GLUT.hs b/src/Graphics/UI/Awesomium/GLUT.hs new file mode 100644 --- /dev/null +++ b/src/Graphics/UI/Awesomium/GLUT.hs @@ -0,0 +1,135 @@ +---------------------------------------------------------------------- +-- | +-- Module : Graphics.UI.Awesomium.GLUT +-- Copyright : (c) 2012 Maksymilian Owsianny +-- License : LGPL-3 (see the file LICENSE) +-- +-- Maintainer : Maksymilian.Owsianny+AwesomiumGLUT@gmail.com +-- Stability : Experimental +-- Portability : Portable? +-- +-- This is a helpful little module for using Awesomium with GLUT. +-- +-- If you do not care for processing input in your program and want +-- all of it go through @Awesomium@, you can simply write: +-- +-- @ +-- motionCallback $= Just (injectMouseMotionGLUT wv) +-- passiveMotionCallback $= Just (injectMouseMotionGLUT wv) +-- keyboardMouseCallback $= Just (injectKeyboardMouseGLUT wv) +-- @ +-- +---------------------------------------------------------------------- + +module Graphics.UI.Awesomium.GLUT + ( injectMouseMotionGLUT + , injectMouseGLUT + , injectKeyboardGLUT + , injectKeyboardMouseGLUT +) where + +import Data.Bits ((.|.)) +import Data.Char +import Graphics.UI.GLUT as GL +import Graphics.UI.Awesomium as Awesomium +import Graphics.UI.Awesomium.Raw as Awesomium + +---------------------------------------------------------------------- + +-- | Injects mouse position to Awesomium. +injectMouseMotionGLUT :: WebView -> Position -> IO () +injectMouseMotionGLUT wv (Position x y) = + injectMouseMove wv (fromIntegral x) (fromIntegral y) + +---------------------------------------------------------------------- + +-- | Injects mouse buttons state to Awesomium. +injectMouseGLUT :: WebView -> Key -> KeyState -> IO () +injectMouseGLUT wv (MouseButton b) Down = + marshalMouseButton b $ injectMouseDown wv +injectMouseGLUT wv (MouseButton b) Up = + marshalMouseButton b $ injectMouseUp wv +injectMouseGLUT wv _ _ = return () + +---------------------------------------------------------------------- + +-- | Injects keyboard state to Awesomium. +injectKeyboardGLUT :: WebView -> Key -> KeyState -> Modifiers -> IO () +injectKeyboardGLUT wv key@(Char k) ks m = + injectKeyboardEvent wv $ defaultKeyboardEvent + { wkeType = marshalType key ks + , wkeModifiers = marshalModifiers m + , wkeText = k + , wkeVirtualKeyCode = marshalKey key} +injectKeyboardGLUT wv key@(SpecialKey k) ks m = + injectKeyboardEvent wv $ defaultKeyboardEvent + { wkeType = marshalType key ks + , wkeModifiers = marshalModifiers m + , wkeVirtualKeyCode = marshalKey key} +injectKeyboardGLUT wv _ _ _ = return () + +---------------------------------------------------------------------- + +-- | Injects both mouse and keyboard state to Awesomium.
