3 . The electronic device of claim 2 , wherein an arrangement of the at least one UI element in the affordance is to vary based on the identified first size.
4 . The electronic device of claim 2 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
determine a previous size before a deactivation of the flexible display;
determine an additional UI element indicating the previous size; and
generate the affordance to include the at least one UI element and the additional UI element.
5 . The electronic device of claim 2 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
identify an application being executed in a foreground;
determine an additional UI element indicating a preset size for the application; and
generate the affordance to include the at least one UI element and the additional UI element.
6 . The electronic device of claim 1 , further comprising:
a battery configured to supply power to the electronic device, and
wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
identify a remaining capacity of the battery; and
change a color of a selected UI element differently from other UI elements among the at least one UI element, based on the remaining capacity of the battery.
7 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to suspend an output of the affordance based on a user's input to the affordance not being received within a preset time.
8 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
determine that the flexible display is activated based on the electronic device being unlocked; and
identify the first size of the exposed area based on the flexible display being activated.
9 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
determine that the flexible display is activated based on an input of activating the deactivated electronic device being received; and
identify the first size of the exposed area based on the flexible display being activated.
10 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
determine a preset number of target applications based on the flexible display being activated;
determine a plurality of app icons respectively representing the target applications, wherein a first app icon of the plurality of app icons is associated with a third size preset for a first target application;
generate the affordance to include the plurality of the app icons;
control the driving module to have the size of the exposed area correspond to the third size when an input of the selection of the first app icon is received based on the affordance; and
execute the first target application in a foreground.
11 . The electronic device of claim 10 , wherein the preset number of the target applications are applications executed in the foreground of the electronic device in a multi-window before the deactivation of the flexible display.
12 . The electronic device of claim 11 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
generate the affordance to include the plurality of app icons and an additional icon representing the multi-window;
control the flexible display to have the size of the exposed area correspond to the size of the multi-window when the input of the selection of the additional icon is received through the affordance; and
execute the target applications in the foreground through the multi-window.
13 . The electronic device of claim 10 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to preset a third size of the first target application, based on history of the size of the exposed area set during the execution of the first target application in the foreground.
14 . The electronic device of claim 13 , wherein the input of the selection of the first app icon is an input of dragging the first app icon to a preset target area in the exposed area.
15 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
determine whether a touch input of a user continues for a preset time when the flexible display is activated based on the touch input of the user;
determine a reference display coordinate of the touch input when the touch input continues for the preset time;
determine the first size of the exposed area;
generate the affordance including graphic elements representing sizes different from the first size; and
control to output the affordance based on the reference display coordinate.
16 . The electronic device of claim 15 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to receive a drag input indicating the second size from the user through the affordance.
17 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
output an additional affordance for adjusting the size of the exposed area of at least a portion of the exposed area when an input of deactivating the flexible display is received;
control the driving module to change the size of the exposed area to a fourth size corresponding to the input to the additional affordance; and
deactivate the flexible display.
18 . A method performed by an electronic device comprising a flexible display with a variable size of an exposed area viewable externally on one side as at least a portion of the flexible display is drawn out from an inside of the electronic device and the flexible display is activated, the method comprising:
identifying a first size of the exposed area of the flexible display;
outputting an affordance on at least a portion of the exposed area of the flexible display, wherein the affordance includes at least one selectable UI elements indicating each of variable sizes of the exposed area, wherein the at least one selectable UI element is determined based on the identified first size;
identifying a target size of the exposed area, based on an input to the affordance; and
controlling a driver configured to move the flexible display to have the size of the exposed area correspond to the target size.
19 . A non-transitory computer-readable storage medium storing instructions that when executed by a processor, cause the processor to perform the method of claim 18 .
