In the foregoing technical solution, the actual display position and the actual display size of the system control are adapted to the window-based application. ## Claims ### Claim 1 A method, applied to an electronic device comprising a screen, the method comprising: displaying a first window, wherein the first window displays a first application, and an area of the first window is less than an area of the screen; and displaying a first system control in a display region of the first window in response to an operation performed by a user on the display of the first application, wherein an actual display position and an actual display size of the first system control are determined based on a default display position and a default display size of the first system control and a scaling ratio of the first window to the screen, the actual display position and the actual display size of the first system control are adapted to the first window, and the default display position and the default display size of the first system control are adapted to the screen. ### Claim 2 (depends on 1) The method according to claim 1, wherein the scaling ratio of the first window to the screen is a first ratio or a second ratio, wherein the first ratio is a ratio of a length of a long edge of the first window to a length of a long edge of the screen, and the second ratio is a ratio of a length of a short edge of the first window to a length of a short edge of the screen. ### Claim 3 A method, applied to an electronic device comprising a screen, the method comprising: displaying a first window, wherein the first window displays a first application, an area of the first window is less than an area of the screen, the first window corresponds to a first virtual screen, and the first virtual screen is created when the first window is created; and displaying a first system control in a display region of the first window in response to an operation performed by a user on the first application, wherein the first system control is displayed based on a default display position and a default display size, and the default display position and the default display size of the first system control are adapted to the first virtual screen. ### Claim 4 (depends on 3) The method according to claim 3, wherein the default display position and the default display size of the first system control are adapted to the first window. ### Claim 5 (depends on 3) The method according to claim 3, wherein a size and a position of the first virtual screen are consistent with a size and a position of the first window. ### Claim 6 (depends on 3) The method according to claim 3, wherein the first system control is any one of the following controls: a message prompt box, a system dialog box, an error pop-up box, a floating box, an input method window, or a system status bar. ### Claim 7 (depends on 3) The method according to claim 3, wherein the position of the first system control changes with the position of the first window, and the position of the first system control does not exceed the position of the first window. ### Claim 8 (depends on 3) The method according to claim 3, wherein the size of the first system control changes with the size of the first window, and the size of the first system control does not exceed a range of the first window. ### Claim 9 (depends on 3) The method according to claim 3, wherein a Z-order value of the first system control is greater than or equal to 2000 and less than or equal to 2999. ### Claim 10 (depends on 3) The method according to claim 3, wherein the first window is a projection window. ### Claim 11 An electronic device, comprising: at least one processor; a memory; and a touchscreen, wherein the memory and the touchscreen are coupled to the at least one processor, the memory is configured to store computer program code, the computer program code comprises computer instructions, and when the at least one processor reads the computer instructions from the memory, the electronic device is enabled to perform operations as follows: displaying a first window, wherein the first window displays a first application, an area of the first window is less than an area of the touchscreen, the first window corresponds to a first virtual screen, and the first virtual screen is created when the first window is created; and displaying a first system control in a display region of the first window in response to an operation performed by a user on the first application, wherein the first system control is displayed based on a default display position and a default display size, and the default display position and the default display size of the first system control are adapted to the first virtual screen. ### Claim 12 (depends on 11) The electronic device according to claim 11, wherein the default display position and the default display size of the first system control are adapted to the first window. ### Claim 13 (depends on 11) The electronic device according to claim 11, wherein a size and a position of the first virtual screen are consistent with a size and a position of the first window. ### Claim 14 (depends on 11) The electronic device according to claim 11, wherein the first system control is any one of the following controls: a message prompt box, a system dialog box, an error pop-up box, a floating box, an input method window, or a system status bar. ### Claim 15 (depends on 11) The electronic device according to claim 11, wherein the position of the first system control changes with the position of the first window, and the position of the first system control does not exceed the position of the first window. ### Claim 16 (depends on 11) The electronic device according to claim 11, wherein the size of the first system control changes with the size of the first window, and the size of the first system control does not exceed a range of the first window. ### Claim 17 (depends on 11) The electronic device according to claim 11, wherein a Z-order value of the first system control is greater than or equal to 2000 and less than or equal to 2999. ### Claim 18 (depends on 11) The electronic device according to claim 11, wherein the first window is a projection window.
