Abstract

The invention relates to the technical field of man-computer interaction, and discloses a multiwindow concurrent display method which comprises the following steps: S1. creating semaphore; S2. creating a plurality of threads, and transferring the created semaphore into the threads; S3. loading the respectively needed resources by the threads, and pausing the threads; and S4. carrying out synchronization control on the threads by controlling the on-off state of the semaphore. The invention can create infinite window threads if computer hardware conditions permit, and can implement resource sharing of all the threads; the threads can concurrently and respectively execute different events by controlling the created semaphore; and the threads are simple to control and operate. Since the thread can be exited as long as after the semaphore is released without waiting for release of other resources, the phenomenon of thread jamming, thread infinite execution or the like can not exist, and much thread mutual exclusion treatment is not needed in the thread.

Description

The concurrent display packing of multiwindow

Technical field

The present invention relates to human-computer interaction technique field, be specifically related to the concurrent display packing of a kind of multiwindow.

Background technology

In windows operating system, all threads all be based on timeslice the operation, so each program the operation in exist thread successively to carry out sequencing problem.And when a plurality of windows of establishment showed in a program, system can distribute a plurality of threads, the scene that window successively occurs successively so always occurred.Therefore in being applied to some software systems of public arena if such situation occurs, the effect that the Total tune property that can influence the whole software system should realize with it.

A kind of technical scheme that can realize the synchronous concurrent display effect of multiwindow does not also appear in the prior art.

Summary of the invention

The technical matters that (one) will solve

Technical matters to be solved by this invention is: how to realize the synchronous concurrent display effect of multiwindow.

(2) technical scheme

For solving the problems of the technologies described above, the invention provides the concurrent display packing of a kind of multiwindow, may further comprise the steps:

S1, establishment semaphore;

S2, create a plurality of threads, the semaphore of being created is imported in each thread;

S3, said a plurality of threads load resource needed separately, then said a plurality of threads are suspended;

S4, said a plurality of threads are carried out synchro control through the switch of controlling said semaphore.

Preferably, the mode of carrying out synchro control among the step S4 is: when discharging said semaphore, the switch of promptly controlling said semaphore is carried out said a plurality of thread when closing simultaneously.

Preferably, the performed incident of each thread is the incident that the current switch that semaphore arranged is out in this thread.

Preferably, among the step S3, if loaded resource is failed then withdrawed from this thread.

Preferably, among the step S1, create four semaphores, i.e. commencing signal amount Start, end signal amount Stop, halt signal amount Pause and release resource signal amount Release.

Preferably, between step S1 and S2, comprise initialization step: said four semaphores of initialization, the switch of halt signal amount Pause is set to out, and the switch of other three semaphores is set to close.

Preferably, said thread is the forms thread.

(3) beneficial effect

The present invention can create unlimited a plurality of forms thread under the situation of computer hardware conditions permit; And realize that all threads realize resource sharings (sharing semaphore); The semaphore of creating out through control; Different events separately carried out and carried out separately to each thread can simultaneously, and is simple to the control operation of thread.And can withdraw from thread after discharging owing to only need wait until semaphore, and and need not wait for the release of other resource, therefore there are not phenomenons such as stuck or unlimited executions of thread of thread, need not do too much Line Procedure Mutually-exclusive processing in thread inside yet.

Description of drawings

Fig. 1 is the method flow diagram of the embodiment of the invention.

Embodiment

Regard to the concurrent display packing of a kind of multiwindow proposed by the invention down, specify in conjunction with accompanying drawing and embodiment.

Principle of the present invention is when creating the display window thread, to use one or more public semaphores; And thread is hovered; Wait all threads that need create all to create after the completion, release semaphore, so; The thread of creating in all programs is carried out after can both discharging (switch in the semaphore is for closing) at semaphore simultaneously, reaches simultaneously display effect synchronously; Can both synchronously in display screen, show simultaneously no matter in program, create what windows, make the whole software system on visual effect, seem smooth and coordinate, not have the collimation error.

To create the concurrent display packing of multiwindow that 3 forms thread A, B, C are the example explanation embodiment of the invention, with reference to figure 1, this method may further comprise the steps below:

1) creates four semaphores: commencing signal amount Start, end signal amount Stop, halt signal amount Pause, release resource signal amount Release;

2) four semaphores of initialization, the switch of Pause semaphore is set to out, and promptly this semaphore has been set to, and the switch of other three semaphores is set to close, and promptly other three semaphores are set to not have; In this step, also can other semaphore be set to out, the purpose of so doing is in order to block thread, it no longer to be carried out;

3) create forms thread A, 4 semaphores creating are imported among the forms thread A, if create failure, program will be skipped the load event of current form thread A;

4) create forms thread B, 4 semaphores creating are imported among the thread B, if create failure, program will be skipped the load event of current thread B;

5) create forms thread C, 4 semaphores creating are imported among the thread C, if create failure, program will be skipped the load event of current thread C;

6) A, B, three threads of C load system resource and the external resource that needs separately, and these three threads are suspended, and wait for commencing signal amount Start; If loaded resource is failed then is withdrawed from this thread;

7) judge whether to exist the thread of needs startup, if the thread that does not exist needs to start, the whole process of then hovering (thread A, B, C are three threads of this process);

8) will create successful thread concludes in the thread tabulation;

9) switch that halt signal amount Pause is set is for closing, and uses this process to realize unification, synchro control to the forms thread through the switch of four semaphores of control.When discharging a certain semaphore, when promptly the switch of control signal amount is for the pass, carry out said a plurality of thread simultaneously, the performed incident of each thread is the current incident that commencing signal amount Start is arranged in this thread.

Above embodiment only is used to explain the present invention; And be not limitation of the present invention; The those of ordinary skill in relevant technologies field under the situation that does not break away from the spirit and scope of the present invention, can also be made various variations and modification; Therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
