From 184df50d3e68aa53bdda06e14b7fe1531d633656 Mon Sep 17 00:00:00 2001 From: Giulio Camuffo Date: Thu, 21 Feb 2013 11:29:21 +0100 Subject: [PATCH] compositor: call configure on surfaces with a null buffer too This way the shell can know when a surface has been unmapped by checking the value returned by weston_surface_is_mapped(surface). The configure handlers have now width and height parameters, so they do not need anymore to check manually the buffer size. If a surface's buffer is NULL the width and height passed to the configure are both 0. Configure is now only called after an attach. The variable weston_surface.pending.newly_attached is set to 1 on attach, and after the configure call is reset to 0. --- src/compositor.c | 36 +++++++++++++++++++++++------------- src/compositor.h | 4 ++-- src/shell.c | 48 +++++++++++++++++++++++++++++------------------- src/tablet-shell.c | 8 ++------ tests/weston-test.c | 6 +++--- 5 files changed, 59 insertions(+), 43 deletions(-) diff --git a/src/compositor.c b/src/compositor.c index 5ff68d7..8f523a8 100644 --- a/src/compositor.c +++ b/src/compositor.c @@ -290,6 +290,7 @@ weston_surface_create(struct weston_compositor *compositor) surface->pending.buffer_transform = surface->buffer_transform; surface->output = NULL; surface->plane = &compositor->primary_plane; + surface->pending.newly_attached = 0; pixman_region32_init(&surface->damage); pixman_region32_init(&surface->opaque); @@ -1279,12 +1280,10 @@ surface_attach(struct wl_client *client, surface->pending.sx = sx; surface->pending.sy = sy; surface->pending.buffer = buffer; + surface->pending.newly_attached = 1; if (buffer) { wl_signal_add(&buffer->resource.destroy_signal, &surface->pending.buffer_destroy_listener); - surface->pending.remove_contents = 0; - } else { - surface->pending.remove_contents = 1; } } @@ -1397,6 +1396,8 @@ surface_commit(struct wl_client *client, struct wl_resource *resource) { struct weston_surface *surface = resource->data; pixman_region32_t opaque; + int buffer_width = 0; + int buffer_height = 0; if (surface->pending.sx || surface->pending.sy || (surface->pending.buffer && @@ -1407,14 +1408,21 @@ surface_commit(struct wl_client *client, struct wl_resource *resource) surface->buffer_transform = surface->pending.buffer_transform; /* wl_surface.attach */ - if (surface->pending.buffer || surface->pending.remove_contents) + if (surface->pending.buffer || surface->pending.newly_attached) weston_surface_attach(surface, surface->pending.buffer); - if (surface->buffer_ref.buffer && surface->configure) + if (surface->buffer_ref.buffer) { + buffer_width = weston_surface_buffer_width(surface); + buffer_height = weston_surface_buffer_height(surface); + } + + if (surface->configure && surface->pending.newly_attached) surface->configure(surface, surface->pending.sx, - surface->pending.sy); + surface->pending.sy, buffer_width, buffer_height); + surface->pending.sx = 0; surface->pending.sy = 0; + surface->pending.newly_attached = 0; /* wl_surface.damage */ pixman_region32_union(&surface->damage, &surface->damage, @@ -2158,11 +2166,14 @@ pointer_handle_sprite_destroy(struct wl_listener *listener, void *data) static void pointer_cursor_surface_configure(struct weston_surface *es, - int32_t dx, int32_t dy) + int32_t dx, int32_t dy, int32_t width, int32_t height) { struct weston_seat *seat = es->private; int x, y; + if (width == 0) + return; + assert(es == seat->sprite); seat->hotspot_x -= dx; @@ -2172,8 +2183,7 @@ pointer_cursor_surface_configure(struct weston_surface *es, y = wl_fixed_to_int(seat->seat.pointer->y) - seat->hotspot_y; weston_surface_configure(seat->sprite, x, y, - es->buffer_ref.buffer->width, - es->buffer_ref.buffer->height); + width, height); empty_region(&es->pending.input); @@ -2240,7 +2250,8 @@ pointer_set_cursor(struct wl_client *client, struct wl_resource *resource, seat->hotspot_y = y; if (surface->buffer_ref.buffer) - pointer_cursor_surface_configure(surface, 0, 0); + pointer_cursor_surface_configure(surface, 0, 0, weston_surface_buffer_width(surface), + weston_surface_buffer_height(surface)); } static const struct wl_pointer_interface pointer_interface = { @@ -2618,14 +2629,13 @@ weston_seat_release(struct weston_seat *seat) } static void -drag_surface_configure(struct weston_surface *es, int32_t sx, int32_t sy) +drag_surface_configure(struct weston_surface *es, int32_t sx, int32_t sy, int32_t width, int32_t height) { empty_region(&es->pending.input); weston_surface_configure(es, es->geometry.x + sx, es->geometry.y + sy, - es->buffer_ref.buffer->width, - es->buffer_ref.buffer->height); + width, height); } static int diff --git a/src/compositor.h b/src/compositor.h index 676e0d9..00d3b22 100644 --- a/src/compositor.h +++ b/src/compositor.h @@ -455,7 +455,7 @@ struct weston_surface { /* All the pending state, that wl_surface.commit will apply. */ struct { /* wl_surface.attach */ - int remove_contents; + int newly_attached; struct wl_buffer *buffer; struct wl_listener buffer_destroy_listener; int32_t sx; @@ -482,7 +482,7 @@ struct weston_surface { * a new buffer has been set up for this surface.
