Display control device, display control method, and display control program

A display control method performed by a display control device including a storage medium that stores i) display setting information indicating setting information of a layer structure of display objects on a terminal screen and setting information of a group to which the display objects belong, ii) operation setting information which is indicated by an operation event which is a combination of an operation target and operation content on a screen and indicates setting content related to the layer structure or a group for each combination of the operation target and the operation content, and iii) display state information indicating a disposition position of each of the display objects on the screen, the method comprising:

• receiving an operation event on a display object on the screen;
• specifying the setting content related to the layer structure or the group indicated by the operation event with reference to the display state information and the operation setting information;
• determining a change in the display setting information based on the specified setting content;
• determining whether the change in the display setting information is a change in the layer structure or a change in setting information of the group;
• in response to determining that the change is a change in the layer structure of the display setting information, reconstructing the display state information using a new layer structure in the changed display setting information;
• in response to determining that the change is a change in the setting information of the group, partially updating the display state information using the change in the setting information of the group, wherein the operation event indicating the change in the setting information of the group comprises i) selecting a plurality of display objects on the screen and ii) inputting a group name for a new group, and wherein the change in the setting information of the group comprises generating the new group for the plurality of display objects selected in the operation event;
• generating updated display state information in which the layer structure of the display objects or the group to which the display objects belong is changed based on the change in the display setting information;
• and
• performing screen display based on the updated display state information.

A non-transitory computer-readable recording medium storing therein a display control program that causes a computer to execute a process comprising:

• storing, by a storage medium, i) display setting information indicating setting information of a layer structure of display objects on a terminal screen and setting information of a group to which the display objects belong, ii) operation setting information which is indicated by an operation event which is a combination of an operation target and operation content on a screen and indicates setting content related to the layer structure or a group for each combination of the operation target and the operation content, and iii) display state information indicating a disposition position of each of the display objects on the screen;
• receiving an operation event on a display object on the screen;
• specifying the setting content related to the layer structure or the group indicated by the operation event with reference to the display state information and the operation setting information;
• determining a change in the display setting information based on the specified setting content;
• determining whether the change in the display setting information is a change in the layer structure or a change in setting information of the group;
• in response to determining that the change is a change in the layer structure of the display setting information, reconstructing the display state information using a new layer structure in the changed display setting information;
• in response to determining that the change is a change in the setting information of the group, partially updating the display state information using the change in the setting information of the group, wherein the operation event indicating the change in the setting information of the group comprises i) selecting a plurality of display objects on the screen and ii) inputting a group name for a new group, and wherein the change in the setting information of the group comprises generating the new group for the plurality of display objects selected in the operation event;
• generating updated display state information in which the layer structure of the display objects or the group to which the display objects belong is changed based on the change in the display setting information;
• and
• performing screen display based on the updated display state information.
