From 5b5c9144872b4e31ba5a041dce585a8ddbbe495d Mon Sep 17 00:00:00 2001 From: Mathias Agopian Date: Thu, 30 Jul 2009 18:14:56 -0700 Subject: fixed some issues with the software renderer when surfaces are made current. there was several issues: - when a surface was made non-current, the last frame wasn't shown and the buffer could stay locked - when a surface was made current the 2nd time, it would not dequeue a new buffer now, queue/dequeue are done when the surface is made current. for this to work, a new query() hook had to be added on android_native_window_t, it allows to retrieve some attributes of a window (currently only width and height). --- libs/ui/FramebufferNativeWindow.cpp | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'libs/ui/FramebufferNativeWindow.cpp') diff --git a/libs/ui/FramebufferNativeWindow.cpp b/libs/ui/FramebufferNativeWindow.cpp index 8c8fd6bb0f9d..8b7ea21d7322 100644 --- a/libs/ui/FramebufferNativeWindow.cpp +++ b/libs/ui/FramebufferNativeWindow.cpp @@ -124,6 +124,7 @@ FramebufferNativeWindow::FramebufferNativeWindow() android_native_window_t::dequeueBuffer = dequeueBuffer; android_native_window_t::lockBuffer = lockBuffer; android_native_window_t::queueBuffer = queueBuffer; + android_native_window_t::query = query; } FramebufferNativeWindow::~FramebufferNativeWindow() { @@ -198,6 +199,23 @@ int FramebufferNativeWindow::queueBuffer(android_native_window_t* window, return res; } +int FramebufferNativeWindow::query(android_native_window_t* window, + int what, int* value) +{ + FramebufferNativeWindow* self = getSelf(window); + Mutex::Autolock _l(self->mutex); + framebuffer_device_t* fb = self->fbDev; + switch (what) { + case NATIVE_WINDOW_WIDTH: + *value = fb->width; + return NO_ERROR; + case NATIVE_WINDOW_HEIGHT: + *value = fb->height; + return NO_ERROR; + } + return BAD_VALUE; +} + // ---------------------------------------------------------------------------- }; // namespace android // ---------------------------------------------------------------------------- -- cgit v1.2.3-59-g8ed1b
