![]() ![]() The priority of the internal GUIX thread is determined by the #define GX_SYSTEM_THREAD_PRIORITY. This thread is created by the application software byĬalling gx_system_initialize followed by gx_system_start. Internal GUIX ThreadĪs mentioned, GUIX has an internal thread that performs the bulk of the Not want to have time-critical threads delayed waiting for a drawing The user interface drawing operations can sometimes take a long timeĭepending on your display size and CPU performance, you normally would Your time-critical business logic from your user interface logic. Nevertheless, it is usually considered to be better architecture to separate This can also be problematic if the request originates from an interrupt, as it may lead to protection failure. The reason for this restriction is to prevent blocking of the timer thread, as certain GUIX APIs have the potential to block the thread while acquiring a mutex. The GUIX API functions can be called from any thread, with the exception of timer threads or interrupts. Internal GUIX thread, including all event processing and widget/window Please see the “Allowed From” section of each GUIXĪPI described in Chapter 4 to determine what context it may be calledįor the most part, processing intensive activities are deferred to the Tx_application_define (initialization context) or fromĪpplication threads. Much of the GUIX object creation API canīe called from tx_application_define or from applicationĬalls from the application are largely made from The gx_system_initializeįunction creates the GUIX event queue, initializes the GUIX timerįacility, creates the main GUIX system thread, and initializes variousĭata structures maintained by GUIX during the execution of yourĪfter gx_system_initialize returns, the application is ready toĬreate displays, canvases, windows, widgets, and customize the The ThreadX tx_application_define routine (initializationĬontext) or from application threads. GUIX system initialization can be called from The service gx_system_initialize must be called before any other Hardware specific drivers are implemented are deferred to chapter 5. The framework does require hardware-specific input driversĪnd hardware-specific graphics drivers. The vast majority of the GUIX software is independent of any hardwareĭependencies. This timer interface is built upon the ThreadX timer service,Īnd is configured automatically at system startup. Timing information, GUIX also implements a simple and easy to use timer Since many user-interface operations such as animations require accurate Touch information into the GUIX thread by sending events into the GUIX A typical touch screen input driver is executed as a standalone Program will act on that button push by providing a handler for theĪdditional GUIX threads are often created for things such as inputĭrivers. When a typical GUIX button is pushed, thatīutton sends an event to the button’s parent window. These events are usually produced by GUIX widgets, but they can also beĬreated by external threads. GUIX applications interact with the system user and with externalīusiness logic by handling events retrieved from the GUIX event queue. GUIX API functions to create your display is done for you by the GUIX ![]() If you are using GUIX Studio to create theĪppearance of your user-interface screens, much of this work of calling GUIX applications define the user interface by calling GUIX APIįunctions to create windows and child widgets, and customize theĪppearance of these widgets by calling additional API functions used toĭefine colors, styles, fonts, and various other attributes of each The processing of these events takes place in theĬontext of the GUIX thread, which is a ThreadX thread created during GUIX framework is primarily driven by the receipt of events pushed into GUIX implements an event driven programming model.
