Detailed Description
In order to further understand the technical scheme and the advantages of the present invention, the following detailed description of the technical scheme and the advantages thereof is provided in conjunction with the accompanying drawings.
As shown in fig. 1, in order to solve the problem of client window coordinate and location management on a Wayland synthesizer, the invention discloses a client window coordinate management implementation method based on Wayland. The method is based on the Wayland protocol, and uses a linked list declared in the protocol to realize the management of the client coordinates and the positions by adding a client window coordinate processing logic; and acquiring data finally submitted by the client by using an interaction result of the client and the synthesizer in the Wayland protocol, and then carrying out logic judgment to confirm the coordinates and the position of the client and implement management and control to complete visual client management.
The Wayland protocol provides a client data source and operation processing (commit) of a user, a window coordinate management module senses (notify) some key operations to the client, such as new creation, deletion, movement, maximization and minimization, detects the position of the client, adopts different strategies (handles) according to different detection and analysis results, and a Wayland synthesizer executes the strategies and sends the strategies to the client (configure); when there are multiple display devices attached or removed (commit), the window coordinate management module will also acquire the relevant information through the compositor, and then update the managed client information.
FIG. 2 is a structure of a linked list used by the present invention for managing client coordinates and locations, and the present invention defines a set of linked list structures to be subsequently used for managing client coordinates and locations as shown in FIG. 2 using wl _ list based on a Wayland synthesizer, and initializes the linked list.
The method for realizing coordinate and position management mainly faces external interfaces such as client request events, screen submission events, keyboard and mouse events and the like, and other similar interfaces also belong to the range capable of being controlled by the method.
In fig. 1, the multiple displays may be understood as corresponding screen submission events, the user operations include keyboard and mouse events, the client refers to specific applications, and the screen and user operation events are acquired by the synthesizer and then it is determined whether configuration information, such as coordinates and positions, of the client needs to be modified.
The client window management method is based on the Wayland protocol and is realized by using a wl _ list linked list structure in Wayland. Generally, there are three cases of triggering location management: close or minimize window, create or restore window, and move window. When the client has the operation actions, the coordinate management can perform corresponding calculation processing on the coordinates of the client for managing and controlling the client. The method mainly comprises the following four functions:
1. when the client is conventionally built newly, the sequence is new, and the method comprises the following steps: new construction of the wayland client, new construction of the x11 client, etc.
2. And (3) when the vacant position exists, new position supplementing is carried out, and the method comprises the following steps: new and delete of the wayland client, new and delete of the x11 client, and the like.
And the deletion operation is that after the client is newly built, the coordinate of the next client adjacent to the newly built client needs to be detected, and if the coordinate of the next client adjacent to the newly built client does not meet the requirement, the coordinate management node corresponding to the next client is deleted from the management linked list.
3. The client can still be managed and controlled to participate in bit filling after moving, and the method comprises the following steps: and removing the corresponding coordinate management node of the client, detecting the next coordinate management node of the client based on whether the client coordinate meets the control condition, and if the client coordinate does not meet the control condition, not performing the next operation.
4. The coordinates of the newly-built client are calculated according to the coordinates of the adjacent last client, and the method comprises the following steps: detecting the position of a newly-built client, inquiring the coordinate position of an adjacent previous client, optimizing the coordinate of the currently-built client based on the coordinate of the adjacent previous client and the like.
The specific embodiment of the client window coordinate management implementation method based on Wayland comprises the following steps:
1. enabling shutdown or minimization of clients
As shown in fig. 3, the interface calls after the compositor or the client sends out an event of closing, minimizing, etc. that cancels display in the current screen, finds out a node of the client in the coordinate position management linked list, and deletes the node.
2. The management of the coordinates and the positions of the newly-built client is realized, and the coordinates of the client on the current screen are mainly set to achieve the control target
As shown in fig. 4, when a new client is created and needs to be displayed on the screen, we can obtain the length and width of the client through the relevant interface of Wayland; according to the obtained length and width, starting to traverse the coordinate management linked list to obtain a client position (the client position comprises the row, the column and the layer) which meets the requirement; if all the clients do not move after being newly built, the arrangement of the clients looks like a neat oblique line, and because the adjacent previous client may have been operated by a user to change the coordinate, the coordinate of the previous client may have some deviation from the theoretical coordinate of the previous position, if the coordinate of the previous client is not considered, the coordinate of the newly built client is directly generated according to the current position, so that the previous client is separated from the oblique line arranged by the clients in visual effect, and in order to avoid the phenomenon, the display interface is tidier, the invention optimizes the coordinate of the newly built client based on the following steps: judging whether the position of the last client adjacent to the position is occupied, if not, directly obtaining the coordinates of the client to be newly built based on the position of the current client; if the client side is occupied, further optimizing the coordinates of the client side through the following steps: acquiring the coordinate of the previous adjacent client, calculating to obtain the final client coordinate through the coordinate of the previous client and the position of the client meeting the requirements at present, and using the final client coordinate for the newly-built client; and finally, traversing the coordinate management linked list and inserting the generated coordinate management node into a corresponding position in the linked list.
3. Self-detection function of nodes in client coordinate position linked list is realized
The function belongs to an internal function of the module, please continue to refer to fig. 4, and the specific function is to detect the validity of the coordinate of the next node after each node is added; when a new node is inserted, the coordinates and the position of the client corresponding to the new node are determined and cannot be changed, and the coordinates of the client need to be obtained according to the adjacent previous client, so that whether the coordinates of the client corresponding to the next node of the new node meet the control requirement needs to be judged: after the newly added node is inserted into the linked list, judging the next node of the node corresponding to the inserted position; because the client coordinate pointed by the newly added linked list node is uncertain, whether the client coordinate of the next node still meets the control requirement needs to be judged; firstly, judging whether the position of the next node is the position which is the same layer of the position corresponding to the current inserted node and is added with 1 in each row and column, if not, not processing; if so, comparing whether the coordinates of the client corresponding to the two nodes are in a preset range, if the client coordinates corresponding to the next node meet the requirements, not processing, and if not, deleting the nodes. After the coordinate management linked list is modified, the nodes which do not meet the control requirements in the linked list are deleted, and the controllability of the linked list is ensured.
4. The detection interface behind the mobile client is realized, and the Wayland window manager detects whether the coordinates of the client need to be managed or not by calling the interface;
as shown in fig. 5, different from the newly-built client, the moved client has its own coordinates, so when the client is moved or coordinates are changed by other actions, the corresponding node is deleted from the coordinate management linked list; after the client moves or the action is finished, the coordinate management module acquires data information submitted by the client through the synthesizer and judges whether the coordinates (x, y) of the client need to be managed or not; if the client coordinates do not meet the requirements, the operation is not carried out; and if the client coordinates meet the management requirements, calculating the appropriate node positions added into the client coordinate position management linked list according to the current coordinates of the client, and inserting the nodes corresponding to the client into the linked list so as to realize more intelligent management and control and improve the management and control program of the client.
And then, invoking the self-detection function of the node in the step three to detect whether the next node is legal or not.
In the present invention, whether the coordinates of the client need to be managed is determined based on whether the coordinates of the client satisfy the expression of the determinant, for example: dividing the whole display area of the client by using a preset value, if the length and the width are divided by 50 pixels, dividing the coordinate x and the coordinate y of the client by 50 respectively to obtain a determinant, and when the remainder is within a preset range, judging that the coordinate of the client meets the control requirement and adding a control linked list.
5. Update interface for realizing client coordinate and position management during screen position change
When a new screen is accessed or events which cause screen changes, such as plugging and unplugging of the screen, are generated, the coordinate management module acquires the events through the window manager and calls the update interface to update the coordinates, the position and the data in the linked list of the client.
Compared with the prior art, the invention has the advantages that:
(1) The module coupling degree is low, only a linked list structure of Wayland is used in codes, the expansion and the transplantation to other window managers can be very convenient, and efficient development is realized.
(2) And the code of the window coordinate management module is completely independently designed and researched, and has complete intellectual property.
(3) The implementation mode is original, and the management of coordinates and positions is realized by fully utilizing the Wayland synthesizer, the Wayland protocol and the communication process of the client and the synthesizer through an interface for sending events to the client.
(4) The method has the advantages that the realization effect is obvious, the new construction and the movement of the client can be effectively managed after the coordinate management module is added, the processing of the coordinate management module on the window can be obviously seen in the use process, and better experience is achieved compared with a window manager without the coordinate management module.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
