This +version of Qt also provides a texture sharing extension that provides more +functionality and convenience for sharing graphical assets with Qt Quick +clients: see the texture-sharing example. + +Compile up both compositor and client. + +If you have the dmabuf-server buffer integration (and you are running Mesa) +then start the compositor with: + +$ QT_WAYLAND_SERVER_BUFFER_INTEGRATION=dmabuf-server ./compositor + + +Note: if you are running a compositor on an X11 desktop, you also need to +set QT_XCB_GL_INTEGRATION=xcb_egl as usual. + +The compositor broadcasts the name of the server buffer integration to +all clients through the hardware integration extension. Therefore, +all you need to do is to start the client with + +$ ./cpp-client -platform wayland + +The client will show all the buffers shared by the compositor. + +For testing on desktop, there is also a shared memory based server buffer +integration that works with any graphics hardware: + +$ QT_WAYLAND_SERVER_BUFFER_INTEGRATION=shm-emulation-server QT_XCB_GL_INTEGRATION=xcb_egl ./compositor + +Note: the shm-emulation-server integration does not actually share graphics +buffers, so it will not give any graphics memory savings. It is intended solely +for testing during development and should never be used in production. |
