From 8c9b8910c1716684080f1ab6058fac1ce7effdad Mon Sep 17 00:00:00 2001 From: David Capello Date: Wed, 1 Nov 2017 22:42:30 -0300 Subject: [PATCH] Use WM_POINTER on Windows 8 platform First version. Still touch support is not working as expected. The pen, mouse, and trackpad are working correctly. (Even the eraser tip of the pen is recognized.) --- CMakeLists.txt | 5 +- src/she/CMakeLists.txt | 1 + src/she/README.md | 1 + src/she/win/system.h | 9 +- src/she/win/winapi.cpp | 42 +++++ src/she/win/winapi.h | 39 +++++ src/she/win/window.cpp | 378 ++++++++++++++++++++++++++++++++++++----- src/she/win/window.h | 9 + 8 files changed, 437 insertions(+), 47 deletions(-) create mode 100644 src/she/win/winapi.cpp create mode 100644 src/she/win/winapi.h diff --git a/CMakeLists.txt b/CMakeLists.txt index dae638be8..eff20c31d 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -405,8 +405,9 @@ if(WIN32) kernel32 user32 gdi32 comdlg32 ole32 winmm shlwapi psapi wininet comctl32 dbghelp) - # Windows XP is the minimum supported platform. - add_definitions(-D_WIN32_WINNT=0x0501 -DWINVER=0x0501) + # Windows Vista is the minimum supported platform but we're defining + # Windows 10 to get the all constant/structure definitions. + add_definitions(-D_WIN32_WINNT=0x0A00 -DWINVER=0x0A00) # We need Unicode support add_definitions(-DUNICODE -D_UNICODE) diff --git a/src/she/CMakeLists.txt b/src/she/CMakeLists.txt index d6b59088b..7328a26ca 100644 --- a/src/she/CMakeLists.txt +++ b/src/she/CMakeLists.txt @@ -122,6 +122,7 @@ if(USE_SKIA_BACKEND) skia/skia_window_win.cpp win/pen.cpp win/vk.cpp + win/winapi.cpp win/window.cpp win/window_dde.cpp) elseif(APPLE) diff --git a/src/she/README.md b/src/she/README.md index f06437852..602bf4205 100644 --- a/src/she/README.md +++ b/src/she/README.md @@ -7,3 +7,4 @@ back-ends: * Previous version were using Allegro 4 (it still uses Allegro 4 on Linux) * Now we use our own implementation on Windows and macOS to handle events, and [Skia](https://skia.org/) to render graphics. +* Minimum Windows platform: Windows Vista diff --git a/src/she/win/system.h b/src/she/win/system.h index 70e8a922c..7b7361f1e 100644 --- a/src/she/win/system.h +++ b/src/she/win/system.h @@ -1,5 +1,5 @@ // SHE library -// Copyright (C) 2012-2016 David Capello +// Copyright (C) 2012-2017 David Capello // // This file is released under the terms of the MIT license. // Read LICENSE.txt for more information. @@ -10,6 +10,7 @@ #include "she/common/system.h" #include "she/win/pen.h" +#include "she/win/winapi.h" namespace she { @@ -21,9 +22,8 @@ public: WindowSystem() { } ~WindowSystem() { } - PenAPI& penApi() { - return m_penApi;
