// dear imgui: Renderer + Platform Binding for Allegro 5 // (Info: Allegro 5 is a cross-platform general purpose library for handling windows, inputs, graphics, etc.) // Implemented features: // [X] Renderer: User texture binding. Use 'ALLEGRO_BITMAP*' as ImTextureID. Read the FAQ about ImTextureID in imgui.cpp. // [X] Platform: Clipboard support (from Allegro 5.1.12) // [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'. // Issues: // [ ] Renderer: The renderer is suboptimal as we need to unindex our buffers and convert vertices manually. // [ ] Platform: Missing gamepad support. // You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this. // If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp. // https://github.com/ocornut/imgui, Original Allegro 5 code by @birthggd // CHANGELOG // (minor and older changes stripped away, please see git history for details) // 2018-06-13: Platform: Added clipboard support (from Allegro 5.1.12). // 2018-06-13: Renderer: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle. // 2018-06-13: Renderer: Backup/restore transform and clipping rectangle. // 2018-06-11: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag. // 2018-04-18: Misc: Renamed file from imgui_impl_a5.cpp to imgui_impl_allegro5.cpp. // 2018-04-18: Misc: Added support for 32-bits vertex indices to avoid conversion at runtime. Added imconfig_allegro5.h to enforce 32-bit indices when included from imgui.h. // 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplAllegro5_RenderDrawData() in the .h file so you can call it yourself. // 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves. // 2018-02-06: Inputs: Added mapping for ImGuiKey_Space. #include <stdint.h> // uint64_t #include <cstring> // memcpy #include "imgui.h" #include "imgui_impl_allegro5.h" // Allegro #include <allegro5/allegro.h> #include <allegro5/allegro_primitives.h> #ifdef _WIN32 #include <allegro5/allegro_windows.h> #endif #define ALLEGRO_HAS_CLIPBOARD (ALLEGRO_VERSION_INT >= ((5 << 24) | (1 << 16) | (12 << 8))) // Clipboard only supported from Allegro 5.1.12 // Visual Studio warnings #ifdef _MSC_VER #pragma warning (disable: 4127) // condition expression is constant #endif // Data static ALLEGRO_DISPLAY* g_Display = NULL; static ALLEGRO_BITMAP* g_Texture = NULL; static double g_Time = 0.0; static ALLEGRO_MOUSE_CURSOR* g_MouseCursorInvisible = NULL; static ALLEGRO_VERTEX_DECL* g_VertexDecl = NULL; static char* g_ClipboardTextData = NULL; struct ImDrawVertAllegro { ImVec2 pos; ImVec2 uv; ALLEGRO_COLOR col; }; // Render function. // (this used to be set in io.RenderDrawListsFn and called by ImGui::Render(), but you can now call this directly from your main loop) void ImGui_ImplAllegro5_RenderDrawData(ImDrawData* draw_data) { // Backup Allegro state that will be modified ALLEGRO_TRANSFORM last_transform = *al_get_current_transform(); ALLEGRO_TRANSFORM last_projection_transform = *al_get_current_projection_transform(); int last_clip_x, last_clip_y, last_clip_w, last_clip_h; al_get_clipping_rectangle(&last_clip_x, &last_clip_y, &last_clip_w, &last_clip_h); int last_blender_op, last_blender_src, last_blender_dst; al_get_blender(&last_blender_op, &last_blender_src, &last_blender_dst); // Setup render state al_set_blender(ALLEGRO_ADD, ALLEGRO_ALPHA, ALLEGRO_INVERSE_ALPHA); // Setup orthographic projection matrix // Our visible imgui space lies from draw_data->DisplayPos (top left) to draw_data->DisplayPos+data_data->DisplaySize (bottom right). { float L = draw_data->DisplayPos.x; float R = draw_data->DisplayPos.x + draw_data->DisplaySize.x; float T = draw_data->DisplayPos.y; float B = draw_data->DisplayPos.y + draw_data->DisplaySize.y; ALLEGRO_TRANSFORM transform; al_identity_transform(&transform); al_use_transform(&transform); al_orthographic_transform(&transform, L, T, 1.0f, R, B, -1.0f); al_use_projection_transform(&transform); } for (int n = 0; n < draw_data->CmdListsCount; n++)
