Abstract

A display control device includes a display control unit and an input unit. The display control unit is configured to display, on a display screen, a first selection area displaying a list of a plurality of first data items, a first scroll bar corresponding to the first selection area, a second selection area displaying a list of a plurality of second data items, and a second scroll bar corresponding to the second selection area. The input unit is configured to receive a selection operation for selecting at least one item from the first data items displayed in the list in the first selection area. In conjunction with the selection operation of the first data item, the display control unit changes the second data items displayed in the list in the second selection area and the display mode of the second scroll bar.

Claims

1. A display control device comprising:

a display control unit configured to display, on a display screen, a first selection area displaying a list of a plurality of first data items, a first scroll bar corresponding to the first selection area, a second selection area displaying a list of a plurality of second data items, and a second scroll bar corresponding to the second selection area; and

an input unit configured to receive a selection operation for selecting at least one item from the first data items displayed in the list in the first selection area,

wherein, in conjunction with the selection operation of the first data item, the display control unit changes the second data items displayed in the list in the second selection area and the display mode of the second scroll bar.

2. The display control device according to claim 1,

wherein the display control unit extracts the first data items and the second data items from at least one data group held in a data table, and displays the list of the first data items and the list of the second data items in the first selection area and the second selection area, respectively.

3. The display control device according to claim 2,

wherein, on the basis of the data table, the display control unit selects the second data items in accordance with the first data item selected by the selection operation, and displays a list of the selected second data items in the second selection area.

4. The display control/device according to claim 3,

wherein, in accordance with the number of the selected second data items displayed in the list in the second selection area, the display control unit changes the display mode of the second scroll bar.
