From 191e0eee7757f6c027ccb9c49b0977633a5c5600 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Kristian=20H=C3=B8gsberg?= Date: Mon, 29 Oct 2012 17:41:46 -0400 Subject: [PATCH] simple-egl: Add a default cursor If clients don't set a cursor, they get whatever the last cursor was before the pointer entered their window. That's a little confusing, so set a pointer on enter to avoid that. The down-side is that simple EGL isn't very simple anymore. https://bugs.freedesktop.org/show_bug.cgi?id=52452 --- clients/simple-egl.c | 33 +++++++++++++++++++++++++++++++++ configure.ac | 2 +- 2 files changed, 34 insertions(+), 1 deletion(-) diff --git a/clients/simple-egl.c b/clients/simple-egl.c index 8823362..fcbea75 100644 --- a/clients/simple-egl.c +++ b/clients/simple-egl.c @@ -32,6 +32,7 @@ #include #include +#include #include #include @@ -47,6 +48,10 @@ struct display { struct wl_seat *seat; struct wl_pointer *pointer; struct wl_keyboard *keyboard; + struct wl_shm *shm; + struct wl_cursor_theme *cursor_theme; + struct wl_cursor *default_cursor; + struct wl_surface *cursor_surface; struct { EGLDisplay dpy; EGLContext ctx; @@ -426,9 +431,24 @@ pointer_handle_enter(void *data, struct wl_pointer *pointer, wl_fixed_t sx, wl_fixed_t sy) { struct display *display = data; + struct wl_buffer *buffer; + struct wl_cursor *cursor = display->default_cursor; + struct wl_cursor_image *image; if (display->window->fullscreen) wl_pointer_set_cursor(pointer, serial, NULL, 0, 0); + else if (cursor) { + image = display->default_cursor->images[0]; + buffer = wl_cursor_image_get_buffer(image); + wl_pointer_set_cursor(pointer, serial, + display->cursor_surface, + image->hotspot_x, + image->hotspot_y); + wl_surface_attach(display->cursor_surface, buffer, 0, 0); + wl_surface_damage(display->cursor_surface, 0, 0, + image->width, image->height); + wl_surface_commit(display->cursor_surface); + } } static void @@ -561,6 +581,12 @@ registry_handle_global(void *data, struct wl_registry *registry, d->seat = wl_registry_bind(registry, name, &wl_seat_interface, 1); wl_seat_add_listener(d->seat, &seat_listener, d); + } else if (strcmp(interface, "wl_shm") == 0) { + d->shm = wl_registry_bind(registry, name, + &wl_shm_interface, 1); + d->cursor_theme = wl_cursor_theme_load(NULL, 32, d->shm); + d->default_cursor = + wl_cursor_theme_get_cursor(d->cursor_theme, "left_ptr"); } } @@ -622,6 +648,9 @@ main(int argc, char **argv) create_surface(&window); init_gl(&window); + display.cursor_surface = + wl_compositor_create_surface(display.compositor); + sigint.sa_handler = signal_int; sigemptyset(&sigint.sa_mask); sigint.sa_flags = SA_RESETHAND; @@ -635,6 +664,10 @@ main(int argc, char **argv) destroy_surface(&window); fini_egl(&display); + wl_surface_destroy(display.cursor_surface); + if (display.cursor_theme) + wl_cursor_theme_destroy(display.cursor_theme); + if (display.shell) wl_shell_destroy(display.shell); diff --git a/configure.ac b/configure.ac index 552c050..35a8097 100644 --- a/configure.ac +++ b/configure.ac @@ -167,7 +167,7 @@ AC_ARG_ENABLE(simple-egl-clients, AM_CONDITIONAL(BUILD_SIMPLE_EGL_CLIENTS, test "x$enable_simple_egl_clients" = "xyes") if test x$enable_simple_egl_clients = xyes; then PKG_CHECK_MODULES(SIMPLE_EGL_CLIENT, - [egl >= 7.10 glesv2 wayland-client wayland-egl]) + [egl >= 7.10 glesv2 wayland-client wayland-egl wayland-cursor]) fi AC_ARG_ENABLE(clients, [ --enable-clients],, enable_clients=yes) -- 2.7.4
