Example one
Fig. 3 is a flowchart of a first embodiment of a screen projection method of the present invention, and the screen projection method is applied to a device initiating screen projection and includes the steps of:
s1, storing a privacy window which is visible in the device initiating screen projection but invisible in the screen projection device into a privacy data queue;
s2, receiving an input control instruction;
s3, judging whether the input control instruction is a control instruction for reverse injection of the screen projection equipment;
s4, if yes, further judging whether the control instruction injected reversely corresponds to the privacy window stored in the privacy data queue;
and S5, if so, distributing the reversely injected control instruction to the next layer of window corresponding to the control instruction.
In this embodiment, first, a privacy window that is visible to the device initiating screen projection but not visible to the screen projection device is stored in a privacy data queue; then, receiving an input control instruction; then, judging whether the input control instruction is a control instruction for reverse injection of the screen projection equipment; then, if yes, further judging whether the control instruction injected reversely corresponds to the privacy window stored in the privacy data queue; and finally, if so, dispatching the reversely injected control instruction to the next layer of window corresponding to the control instruction.
In this embodiment, it should be noted that, in the prior art, a screen projection screen displayed on a screen projection device is not completely consistent with a real screen displayed by a device initiating screen projection, and there are slight differences, for example, when a user uses a privacy screen projection mode, the screen projection screen does not show a status bar window of the device initiating screen projection and a hover ball window for prompting a screen projection status, and because these screens do not need to be projected, these screens cannot be seen on the screen projection device. In the screen projection mode, a user can reversely control the equipment for initiating the screen projection by clicking the picture by using a mouse of the screen projection equipment and the like, so that if the user clicks the area corresponding to the picture which cannot be seen on the screen projection equipment, the user can find that the due reaction cannot be obtained, thereby suspected that the screen projection function has a problem and cannot normally use the screen projection function. Therefore, in this embodiment, in order to solve the above technical problem, a privacy window that is visible to the device initiating the screen projection but not visible to the screen projection device is stored in a privacy data queue; receiving an input control instruction; judging whether the input control instruction is a control instruction injected reversely by the screen projection equipment; if yes, further judging whether the control instruction injected reversely corresponds to the privacy window stored in the privacy data queue; and if so, dispatching the control instruction subjected to the reverse injection to the next layer window corresponding to the control instruction. The scheme that the screen projection equipment can normally and reversely control the screen projection equipment is achieved under the condition that the screen projection picture displayed on the screen projection equipment is different from the real picture displayed by the screen projection equipment, and user experience is improved.
In this embodiment, it should be noted that the screen projection method of this embodiment is applicable to a device that can initiate screen projection, such as a mobile phone and a tablet computer; the screen projecting device in the screen projecting method of the embodiment is provided with one or more input components such as a mouse, a keyboard, a touch screen or a touch pad, so as to facilitate the input of the control instruction of the reverse injection.
Specifically, in this embodiment, the privacy window that is visible to the device initiating screen projection but invisible to the device initiating screen projection is stored in the privacy data queue, that is, the window that is visible to the device initiating screen projection but invisible to the device initiating screen projection is distinguished and stored in the privacy data queue separately, so as to provide a basis for subsequently distinguishing whether the input control instruction corresponds to the window. The window visible in the device initiating the screen projection but invisible in the screen projection device includes various windows visible in the device initiating the screen projection but invisible in the screen projection device, for example, a status bar window of the device initiating the screen projection and/or a hover ball window for prompting the screen projection status, and the like. It will be appreciated that windows that are all visible to the device initiating the screen projection but are not visible to the screen projection device are stored in the private data queue.
Specifically, in the present embodiment, an input control instruction is received. In the screen projection mode, the input control command may be a control command input by the device initiating the screen projection, or may be a control command injected reversely by the screen projection device. In order to distinguish and process the two control instructions with different input modes, the two types of control instructions need to be distinguished first subsequently.
Specifically, in this embodiment, it is determined whether the input control command is a control command for reverse injection by the screen projection device. Optionally, it is determined whether the input control instruction is a control instruction injected reversely by the screen projection device through an InputDispatch (input dispatch) of the device initiating the screen projection.
Specifically, in this embodiment, if yes, it is further determined whether the reversely injected control instruction corresponds to the privacy window stored in the privacy data queue. That is, after it is determined that the input control command is the control command reversely injected by the screen projection device through judgment, it is further judged whether the control command reversely injected corresponds to the privacy window stored in the privacy data queue, so as to distinguish two different situations that the control command reversely injected corresponds to or is not the privacy window stored in the privacy data queue in the following.
Specifically, in this embodiment, if yes, the control instruction for reverse injection is dispatched to the next layer window corresponding to the control instruction. The next window corresponding to the above-mentioned window refers to the next window pointed by the coordinate value of the control instruction for reverse injection corresponding to the screen of the device initiating screen projection. For example, on the device side initiating screen projection, a hover ball window for prompting a screen projection state belongs to the privacy window, and is located just above a movie window of certain video playing software in a screen projection picture, at this time, a part or all of the movie window is located below the hover ball window, and cannot be displayed completely or cannot be displayed completely, wherein the part which cannot be displayed is called a next-layer window; at the screen projection equipment side, because the floating ball window is not displayed in the screen projection picture, the movie window can be displayed in the screen projection picture without blocking, if a user just selects a part of the movie window, which is positioned below the floating ball window, at the equipment side initiating the screen projection through the screen projection equipment, namely the next layer window, the input control instruction is firstly judged as a control instruction injected reversely by the screen projection equipment, and then is further judged as a control instruction corresponding to the privacy window stored in the privacy data queue, namely the floating ball window, at this moment, a coordinate value corresponding to the control instruction injected reversely in the screen of the equipment initiating the screen projection is obtained, and the control instruction injected reversely is distributed to the next layer window, namely the movie window, to which the coordinate value points.
The method has the advantages that the privacy window which is visible on the screen projection initiating device but not visible on the screen projection initiating device is stored in the privacy data queue; receiving an input control instruction; judging whether the input control instruction is a control instruction injected reversely by the screen projection equipment; if yes, further judging whether the control instruction injected reversely corresponds to the privacy window stored in the privacy data queue; and if so, dispatching the control instruction subjected to the reverse injection to the next layer window corresponding to the control instruction. The scheme that the screen projection equipment can normally and reversely control the screen projection equipment is achieved under the condition that the screen projection picture displayed on the screen projection equipment is different from the real picture displayed by the screen projection equipment, and user experience is improved.
Example two
Based on the above embodiment, in order to facilitate the implementation of the present invention, the storing, in a privacy data queue, a privacy window that is visible to the device initiating the screen projection but not visible to the screen projection device includes the following steps:
s11, storing a privacy window which is visible in the screen projection initiating device but invisible in the screen projection initiating device in a privacy data queue in a coordinate range of a corresponding area of a screen of the screen projection initiating device.
Specifically, in this embodiment, by storing the coordinate range of the privacy window visible to the device initiating screen projection but invisible to the device initiating screen projection in the area corresponding to the screen of the device initiating screen projection in the privacy data queue, convenience is provided for subsequently judging whether the reversely injected control instruction corresponds to the privacy window stored in the privacy data queue.
The method has the advantages that the coordinate range of the privacy window visible in the screen projection initiating device but invisible in the screen projection initiating device in the area corresponding to the screen of the screen projection initiating device is stored in the privacy data queue; receiving an input control instruction; judging whether the input control instruction is a control instruction injected reversely by the screen projection equipment; if yes, further judging whether the control instruction injected reversely corresponds to the privacy window stored in the privacy data queue; and if so, dispatching the control instruction subjected to the reverse injection to the next layer window corresponding to the control instruction. The scheme that the screen projection equipment can normally and reversely control the screen projection equipment is achieved under the condition that the screen projection picture displayed on the screen projection equipment is different from the real picture displayed by the screen projection equipment, and user experience is improved.
EXAMPLE III
Based on the second embodiment, in order to facilitate implementation of the present invention, as shown in fig. 4, the determining whether the reversely injected control instruction corresponds to the privacy window stored in the privacy data queue includes the following steps:
s41, obtaining a coordinate value corresponding to the control instruction injected reversely on the screen of the device initiating screen projection;
s42, judging whether the control instruction injected reversely corresponds to the privacy window stored in the privacy data queue or not by judging whether the coordinate value falls into the coordinate range or not.
Specifically, in this embodiment, coordinate values corresponding to the control instruction for reverse injection on the screen of the device initiating screen projection are obtained; and judging whether the control instruction injected reversely corresponds to the privacy window stored in the privacy data queue or not by judging whether the coordinate value falls into the coordinate range or not. If the coordinate value falls into the coordinate range, the control instruction injected reversely corresponds to the privacy window stored in the privacy data queue; otherwise, the control instruction injected reversely does not correspond to the privacy window stored in the privacy data queue.
