Abstract
A controller is configured to accept a user input from an input interface, access a memory storing tree information that includes pieces of information about a plurality of hierarchized elements, and generate a screen command related to a display screen of a display. The controller causes elements included in the tree information to be displayed on the display. When an element located in the center in the width direction of the display receives an expanding operation, child elements are expanded one layer below the element. When a parent element of child elements goes beyond the center in the width direction, in response to the width direction slide operation, the child elements subordinate to the element are hidden on the display.
Claims18
A tree-information-providing device comprising:
- a memory;
- and
- a controller configured to accept a user input from an input interface, access the memory configured to store tree information that includes pieces of information about many hierarchized elements, and generate a screen command related to a display screen of a display, wherein
- the controller is configured to execute:
- causing the elements included in the tree information to be displayed on the display, in response to a user input for display of the elements;
- accepting a user input for an expanding operation for any of the elements displayed on the display;
- in response to the expanding operation, displaying the element targeted by the expanding operation in a vertical reference region extending in a longitudinal direction, the vertical reference region being defined at a particular position in a width direction of the display;
- expanding child elements in a width direction region extending in the width direction one layer below the element on the display, if the element displayed in the vertical reference region has received the expanding operation, and one or more child elements are subordinate to the element on a layer lower than the element in the tree information;
- accepting a user input for a width direction slide operation;
- causing all the elements included in the width direction region, which are targeted by the width direction slide operation, to laterally slide together in the width direction, in response to the width direction slide operation;
- and
- causing child elements subordinate to an element that has gone beyond the vertical reference region in the width direction to be hidden on the display.
A non-transitory computer readable medium having thereon instructions for tree information provision that a controller is caused to execute, the controller being configured to accept a user input from an input interface, access a memory storing tree information that includes pieces of information about a plurality of hierarchized elements, and generate a screen command related to a display screen of a display, wherein the instructions, when executed on a computer, perform a method for causing the controller to realize:
- causing the elements included in the tree information to be displayed on the display, in response to a user input for display of the elements;
- accepting a user input for an expanding operation for any of the elements displayed on the display;
- in response to the expanding operation, displaying the element targeted by the expanding operation in a vertical reference region extending in a longitudinal direction, the vertical reference region being defined at a particular position in a width direction of the display;
- if the element displayed in the vertical reference region has received the expanding operation, and one or more child elements are subordinate to the element on a layer lower than the element in the tree information, expanding and displaying the child elements in a width direction region extending in the width direction one layer below the element on the display;
- accepting a user input for a width direction slide operation;
- causing all the elements included in the width direction region, which are targeted by the width direction slide operation, to laterally slide together in the width direction, in response to the width direction slide operation;
- and
- causing child elements subordinate to an element that has gone beyond the vertical reference region in the width direction to be hidden on the display.
