Screen projection display method and system, terminal device, and storage medium

A terminal device, comprising a non-transitory memory, at least one processor, and a computer program that is stored in the memory and that is executable by the at least one processor, wherein when executing the computer program, the at least one processor is configured to perform:

• after receiving screen projection request information sent by a source device, obtaining first window data of a first application enabled by the source device, wherein the first window data comprises display content corresponding to two windows opened in the first application enabled by the source device, the two windows comprise a first window and a second window, the first window is a window that has not been displayed on the source device before the first window data is obtained, the second window is a window that has been displayed on the source device before the first window data is received, the second window is a window displayed on the source device when the first window data is received, and the source device does not display any content of the first window when the first window data is received, and wherein in the first window data a window component of the first window is in an active state, a layer of the window component of the first window is in a visible state, a window component of the second window is in the active state, and a layer of the window component of the second window is in the visible state;
• displaying a third window and a fourth window simultaneously, wherein the third window is used to display window content corresponding to the first window in a first area of a display interface of a target device and the fourth window is used to display window content corresponding to the second window in a second area of the display interface of the target device, and wherein the third window and the fourth window are user-operable windows;
• and
• in response to an operation performed on the third window, refreshing the displayed window content of the third window, wherein the refreshing of the displayed window content of the third window does not affect any currently displayed content of the source device;
• and
• when a fifth window opened from the third window is detected, adding the fifth window to the second area in the display interface of the target device for display, and closing the fourth window displayed in the display interface;
• and
• when a sixth window opened from the fourth window is detected, adding, for display, the sixth window to the second area in the display interface of the target device to cover the fourth window displayed in the display interface.

A method, applied to a system comprising a source device and a target device, the method comprising:

• sending, by the source device, first window data of a first application enabled by the source device, wherein the first window data comprises display content corresponding to two windows opened in the first application enabled by the source device, the two windows comprise a first window and a second window, the first window is a window that has not been displayed on the source device before the first window data is sent, and the second window is a window that has been displayed on the source device before the first window data is sent, the second window is a window displayed on the source device when the first window data is received, and the source device does not display any content of the first window when the first window data is received, wherein in the first window data a window component of the first window is in an active state, a layer of the window component of the first window is in a visible state, a window component of the second window is in the active state, and a layer of the window component of the second window is in the visible state;
• and
• receiving, by the target device, the first window data, and displaying a third window and a fourth window simultaneously, wherein the third window is used to display window content corresponding to the first window in a first area of a display interface of the target device and the fourth window is used to display window content corresponding to the second window in a second area of the display interface of the target device, and wherein the third window and the fourth window are user-operable windows;
• and
• in response to an operation performed on the third window, refreshing, by the target device, the displayed window content of the third window, wherein the refreshing of the displayed window content of the third window does not affect any currently displayed content of the source device;
• and
• when a fifth window opened from the third window is detected, adding, by the target device, the fifth window to the second area in the display interface of the target device for display, and closing the fourth window displayed in the display interface;
• and
• when a sixth window opened from the fourth window is detected, adding, for display by the target device, the sixth window to the second area in the display interface of the target device to cover the fourth window displayed in the display interface.
