Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to prevent the combination form of the designated graph from being changed at will and improve the user experience, the embodiment of the invention provides a method and a device for protecting the combination form of the graph in the document, an electronic device and a storage medium.

The method for protecting the graphic combination form in the document provided by the embodiment of the invention can be applied to any electronic equipment needing to protect the graphic combination form in the document, such as: a computer or a mobile terminal, etc., which are not limited herein. For convenience of description, the electronic device is hereinafter referred to simply as an electronic device.

As shown in fig. 1, a specific processing flow of the method for protecting a graphic combination form in a document according to an embodiment of the present invention includes:

and step S101, judging whether the selected current graph is a combined graph.

In practice, the electronic device may determine whether the selected current graphic is a combined graphic. In a specific embodiment, whether the value of the attribute type (type) is the attribute type value corresponding to the combined graph preset by the program developer can be determined by reading the attribute type (type) of the graph, if so, the graph is a combined graph, for example, when the value of the attribute type can be 6, the graph represents that the graph is a combined object, and the manner of determining whether the selected current graph is a combined graph is not particularly limited.

If the judgment result is yes, namely the selected current graph is the combined graph, executing the step S102; if the judgment result is negative, namely the selected current graph is not the combined graph, the operation is ended.

And step S102, reading the protection combination form attribute information of the current graph.

Step S103, judging whether the attribute value of the protection combination form attribute of the current graph is valid or invalid; the attribute value of the protection combination form attribute is preset by a user.

In practice, the attribute value of the protection combination form attribute may be preset by the following steps:

judging whether a graphic combination form protection state change instruction is received or not after judging that the selected current graphic is a combined graphic; if a graphic combination form protection state change instruction is received, reading the protection combination form attribute information of the current graphic; judging whether the attribute value of the protection combination form attribute of the current graph is effective or ineffective; if the attribute value of the protection combination form attribute of the current graph is invalid, modifying the attribute value of the protection combination form attribute of the current graph to be valid; and if the attribute value of the protection combination form attribute of the current graph is valid, modifying the attribute value of the protection combination form attribute of the current graph to be invalid.

If the judgment result is valid, executing step S104; if the result of the judgment is invalid, step S105 is executed.

And step S104, forbidding the current graphic response canceling graphic combination operation.

In one embodiment, the electronic device may display the graphical combination function operation button on the document editing interface as invalid or display the graphical combination function operation button in the right mouse button menu as invalid.

And step S105, canceling the graphic combination operation in response to the current graphic.

Therefore, by applying the embodiment of the invention, if a certain selected current graph is a combined graph, the attribute information of the protection combined form attribute of the current graph is read, and when the protection combined form attribute value of the current graph is effective, the current graph can be prohibited from responding to cancel the graph combining operation, so that the combined form of the specified graph cannot be changed randomly, and the user experience is improved.

Another flowchart of a method for protecting a graphic combination pattern in a document according to an embodiment of the present invention is shown in fig. 2, and includes:

step S201, determining whether the selected current graph is a combined graph.

If the judgment result is yes, namely the selected current graph is the combined graph, executing the step S202; if the judgment result is negative, namely the selected current graph is not the combined graph, the operation is ended.

Step S202, judging whether a graphics combination form protection state change instruction is received.

In practice, the electronic device may determine whether a graphics combination protection state change instruction is received. In a specific implementation manner, whether a graphic combination form protection state change button preset in a document display interface is clicked or not can be judged; or judging whether a graphic combination form protection state change button in a right mouse button menu is clicked.

If the result of the determination is yes, that is, the graphics combination form protection state change instruction is received, then step S203 is executed; if the result of the determination is no, that is, if the graphics combination status change instruction is not received, step S213 is executed.

Step S203, reading the protection combination form attribute information of the current graph.

And reading the protection combination form attribute information of the current graph.

Step S204, judging whether the attribute value of the protection combination form attribute of the current graph is valid or invalid.

If the judgment result is invalid, executing step S205; if the result of the judgment is valid, step S208 is executed.

In step S205, a password setting dialog is displayed.

It may be implemented to display a password setting dialog box to allow the user to set the password.

Step S206, saving the password set by the user, and modifying the attribute value of the protection combination form attribute of the current graph to be effective.

In practice, if the user sets the password, the electronic device can encrypt the password set by the user and store the encrypted password in the password storage position in order to prevent the directly stored number from being easily stolen by others. And the attribute value of the protection combination form attribute of the current graph can be modified to be effective.

When the user modifies the attribute value of the protection combination form attribute of the current graph into valid, the password is set, and if other people do not know the password, the graph combination operation cannot be cancelled. For example: after the user A edits the document, the other users want to modify the text content, but the other users do not want to cancel the graphic combination. By the method, other people can be prohibited from canceling the graphic combination operation, editing of other contents in the document is not influenced, and user experience is improved.

Through the above steps S205 and S206, the protection combination form attribute information of the current graphic is modified from invalid to valid, that is, the protection state of the graphic combination form is changed from the unprotected state to the protected state.

And step S207, forbidding the current graphic response canceling graphic combination operation. The flow ends.

Step S207 may be the same as step S104, and is not described herein.

In step S208, a password input dialog is displayed.

In step S204, when the determination result that the attribute value of the protection combination shape attribute of the current graphic is valid or invalid is valid, a password input dialog box is displayed to allow the user to input a password.

In step S209, it is determined whether the input password is a password set in advance by the user.

It is practicable to judge whether the input password is a password set in advance by the user. Specifically, it may be determined whether the password input this time is the same as the password set when the attribute value of the protection combination form attribute of the current graphic is modified from invalid to valid.

If the result of the judgment is no, that is, the input password is not the password set by the user in advance, step S210 is executed; if the result of the judgment is yes, the input password is a password set by the user in advance, and step S211 is performed.

And step S210, forbidding the current graphic response canceling graphic combination operation. The flow ends.

And step S211, modifying the attribute value of the protection combination form attribute of the current graph into invalid.

It is practicable that if the input password is a password set by a user in advance, the protection combination form attribute value of the current graphic may be modified to be invalid.

In the above steps S209 and S211, the protection combination type attribute information of the current graphics is changed from valid to invalid, that is, the protection state of the graphics combination type is changed from the protected state to the unprotected state.

In this embodiment, in order to further protect the graphic combination form from being modified randomly, a protection password may be set in the process of changing the attribute of the protection combination form from invalid to valid, so that a user without the password cannot change the attribute of the protection combination form from valid to invalid.

And step S212, canceling the graphic combination operation in response to the current graphic. The flow ends.

Step S213, reading the protection combination shape attribute information of the current graph.

In step S202, in the step of determining whether a command for changing the protection state of the graphic combination form is received, if the determination result is negative, the step is executed to read the attribute information of the protection combination form of the current graphic.

Step S214, judging whether the attribute value of the protection combination form attribute of the current graph is valid or invalid.

If the result of the judgment is invalid, step S215 is executed. If the result of the judgment is valid, step S216 is executed.

Step S215, the graphic combination operation is cancelled in response to the current graphic. The flow ends.

In step S216, a password input dialog is displayed.

In step S217, it is determined whether the input password is a password set in advance by the user.

It is practicable to judge whether the input password is a password set in advance by the user.

If the result of the judgment is no, that is, the input password is not the password set by the user in advance, step S218 is performed; if the result of the judgment is yes, the input password is a password set by the user in advance, and step S219 is performed.

In step S218, the current graphics response cancellation graphics combination operation is prohibited. The flow ends.

Step S219, modifying the attribute value of the protection combination form attribute of the current graph to be invalid. Step S215 is performed.

By applying the embodiment, when the selected current graph is judged to be the combined graph and the graph combination state is to be cancelled, the input password dialog box can be displayed, whether the current user has the permission to cancel the combination form is judged by judging whether the input password is the password preset by the user, and if the password is correct, the attribute value of the protection combination form attribute of the current graph is modified to be valid; and if the password is incorrect, forbidding the current graphic response to cancel the graphic combination operation. By the mode, the user without permission can be prevented from randomly modifying the graphic combination form, and the user experience is improved.

Corresponding to the method for protecting the combination form, an embodiment of the present invention further provides a method for prohibiting the combination of the graphics in the document, as shown in fig. 3, including:

step S301, judging whether the number of the selected current graphs is more than or equal to two.

If the judgment result is yes, namely the number of the selected current graphs is greater than or equal to two, executing the step S302; and if the judgment result is negative, namely the number of the selected current graphs is not more than or equal to two, ending the operation.

Step S302, reading the forbidden combination form attribute information of each current graph.

Step S303, judging whether the attribute value of the forbidden combination form attribute of each current graph is valid or invalid; the attribute value of the forbidden combination form attribute is preset by a user.

The attribute value of the forbidden combination form attribute can be preset by adopting the following steps:

judging whether a state change instruction of a pattern forbidden combination form is received or not after judging that the number of the selected current patterns is greater than or equal to two; if a state change instruction of a figure forbidden combination form is received, reading the attribute information of the forbidden combination form of each current figure; judging whether the attribute value of the forbidden combination form attribute of each current graph is effective or ineffective; for each current graph with the attribute value of the forbidden combination form attribute being invalid, modifying the attribute value of the forbidden combination form attribute of each current graph with the attribute value of the forbidden combination form attribute being invalid into valid; and aiming at each current graph with the attribute value of the forbidden combination form attribute being effective, modifying the attribute value of the forbidden combination form attribute of each current graph with the attribute value of the forbidden combination form attribute being effective into invalid.

For each current graph with the attribute value of the forbidden combination form attribute being effective, the combination operation of each selected current graph can be forbidden; or forbidding the combination operation on each current graph with the attribute value of the forbidden combination form attribute being effective, and combining the other selected current graphs. In some cases, for example, in practical application, 8 small graphics are overlapped, and the formats of 7 graphics are to be changed in batch, so that for convenient operation, the graphics which are not to be subjected to format change are prohibited from being combined, and then the 7 graphics are combined, so that the situations of wrong selection or bad selection and the like are avoided, and the user experience is high.

Executing step S304 for each current graph for which the attribute value of the forbidden combination form attribute is valid; step S305 is executed for each current graphic whose attribute value of the prohibited combined form attribute is invalid.

Step S304, for each current graph whose attribute value of the forbidden combination form attribute is effective, forbidding the combination operation of each current graph whose attribute value of the forbidden combination form attribute is effective.

It is practicable to prohibit the combination operation for each current graph whose attribute value of the combination prohibition form attribute is valid. In a specific embodiment, the graphic combination function operating button on the document editing interface may be displayed as invalid or the graphic combination function operating button in the right mouse button menu may be displayed as invalid.

Step S305 responds to the operation of combining the graphics for each current graphic for which the attribute value of the combination prohibition form attribute is invalid.

In step S303, if it is determined that the attribute value of the forbidden combination form attribute of each current graph is valid or invalid, if it is determined that the current graph including the forbidden combination form attribute is valid, the current graph whose attribute value of the forbidden combination form attribute is valid may be forbidden to be combined, and the operation of combining graphs for each current graph whose attribute value of the forbidden combination form attribute is invalid may be responded; or forbidding the combination operation on each selected current graph, namely forbidding the combination operation on all the selected current graphs as long as the attribute value containing the forbidden combination form attribute is the valid current graph.

Therefore, by applying the embodiment of the invention, if the number of the selected current graphs is more than or equal to two, the attribute information of the forbidden combination form of each current graph is read, and when the attribute value of the forbidden combination form attribute is the effective current graph, the combination operation of each current graph with the forbidden combination form attribute as the effective attribute value is forbidden, so that the combination form of the designated graph cannot be randomly changed, and the user experience is improved.

Another flowchart of a method for prohibiting combining graphics in a document according to an embodiment of the present invention is shown in fig. 4, and includes:

step S401, judging whether the number of the selected current graphs is more than or equal to two.

If the judgment result is yes, namely the number of the selected current graphs is greater than or equal to two, executing the step S402; and if the judgment result is negative, namely the number of the selected current graphs is not more than or equal to two, ending the operation.

In step S402, it is determined whether or not a graphics prohibition combination mode state change instruction is received.

In practice, the electronic device may determine whether a change command of the status of the combination prohibition mode is received. In a specific implementation manner, whether a graphic forbidden combination form state change button preset in a document display interface is clicked or not can be judged; or judging whether a graphic forbidden combination form state change button in a right mouse button menu is clicked or not.

If the result of the determination is yes, that is, the graphics prohibition combination status change instruction is received, then step S403 is executed; if the result of the determination is no, that is, if the graphics prohibition combination mode state change instruction is not received, step S413 is executed.

Step S403, reading the forbidden combination form attribute information of each current graph.

It is practicable to read the prohibited combination form attribute information of each of the current patterns.

Step S404, determining whether the attribute value of the forbidden combination shape attribute of each current graph is valid or invalid.

Executing step S405 for each current graph for which the attribute value of the forbidden combination form attribute is invalid; step S408 is executed for each current graph for which the attribute value of the prohibited combined form attribute is valid.

In step S405, a password setting dialog is displayed.

Step S406, saving the password set by the user, and modifying the attribute value of the forbidden combination form attribute of each current graph with the invalid attribute value of the forbidden combination form attribute to be valid.

In practice, if the user sets the password, the electronic device can encrypt the password set by the user and store the encrypted password in the password storage position in order to prevent the directly stored number from being easily stolen by others. And the attribute value of the forbidden combination form attribute of each current graph can be modified to be effective.

In the above steps S405 and S406, the attribute value of the prohibited combination type attribute of each current graphic whose attribute value of the prohibited combination type attribute is invalid is modified to valid, that is, the prohibited combination type of the graphic is changed from the unprotected state to the protected state.

Step S407, prohibiting the combination operation on each current graph whose attribute value of each combination-prohibited form attribute is valid. The flow ends.

Step S407 may be the same as step S304, and is not described herein.

In step S408, a password input dialog is displayed.

An enter password dialog may be displayed to allow the user to enter a password.

In step S409, it is determined whether the input password is a password set in advance by the user.

It is practicable to judge whether the input password is a password set in advance by the user. Specifically, it may be determined whether the password input this time is the same as the password set when the attribute value of the forbidden combination form attribute of the current graph is modified from invalid to valid.

If the result of the judgment is no, that is, the input password is not the password set by the user in advance, step S410 is executed; if the result of the judgment is yes, the input password is a password set by the user in advance, and step S411 is performed.

And step S410, forbidding the combination of the selected current graphs. The flow ends.

Step S411, the attribute value of the forbidden combination form attribute of each current graph, the attribute value of the forbidden combination form attribute of which is effective, is modified to be invalid.

It is practicable that if the input password is a password set by a user in advance, the forbidden combination shape attribute value of the current figure may be modified to be invalid.

In the above steps S409 and S411, the attribute value of the prohibited combination type attribute of each current graphic whose attribute value of the prohibited combination type attribute is valid is modified to be invalid, that is, the protection state of the prohibited combination type attribute of the graphic is changed from the protected state to the unprotected state.

In this embodiment, in order to further protect the combined form of the graphics from being modified randomly, a protection password may be set in the process of changing the property of the combination prohibition form from invalid to valid, so that a user without the password cannot change the property of the combination prohibition form from valid to invalid.

Step S412, responding to the operation of combining the selected current graphics. The flow ends.

Step S413, reading the forbidden combination mode attribute information of each current graph.

Step S414, determining whether the attribute value of the forbidden combination form attribute of each current graph is valid or invalid.

Executing step S415 for each current graph for which the attribute value of the forbidden combination form attribute is invalid; step S416 is performed for each current graph for which the attribute value of the prohibited combined form attribute is valid.

Step S415, responding to the operation of combining the selected current graphics. The flow ends.

In step S416, a password input dialog is displayed.

In step S417, it is determined whether the input password is a password set in advance by the user.

If the result of the judgment is no, that is, the input password is not the password set by the user in advance, step S418 is performed; if the result of the judgment is yes, the input password is a password set by the user in advance, and step S419 is performed.

Step S418, prohibiting the combination operation on each current graph whose attribute value of the combination-prohibited form attribute is valid. The flow ends.

Step S419, the attribute value of the forbidden combination form attribute of each current graph, the attribute value of the forbidden combination form attribute of which is effective, is modified to be invalid. Step S415 is performed.

By applying the embodiment, when the number of the selected current graphs is judged to be more than or equal to two and the graphs with the forbidden combination form attribute values being valid are required to be combined, a dialog box for inputting the password can be displayed, whether the current user has the authority of graph combination is judged by judging whether the input password is a password preset by the user, and if the password is correct, the attribute values of the forbidden combination form attributes of the current graphs with the forbidden combination form attribute values being valid are modified to be invalid; and if the password is incorrect, forbidding the combination operation on each current graph with the attribute value of the forbidden combination form attribute being valid. By the mode, the user without permission can be prevented from randomly modifying the graphic combination form, and the user experience is improved.
