Abstract: The present disclosure relates to window display methods and electronic devices. In one example window display method, an electronic device displays a first window and a second window, where a screen direction of the electronic device is a first direction, the screen direction is one of a portrait direction, a landscape direction, a reverse portrait direction, and a reverse landscape direction, and a display direction of the first window is the first direction. When detecting that the screen direction of the electronic device changes from the first direction to a second direction, the electronic device keeps a display direction of the second window unchanged, and rotates the first window, so that the display direction of the first window is the second direction.

Abstract: In accordance with an embodiment, an application display method includes: starting an application on an electronic device; detecting a switching operation of switching a screen orientation of the electronic device from a portrait orientation to a landscape orientation; in response to detecting the switching operation, changing a window orientation of display resource information of the application to the portrait orientation; and sending the changed display resource information to the application, so that the application loads a portrait layout of an application window in the landscape orientation.

Abstract: A device control method includes: a destination projection device, after displaying a projection window of a source projection device, that generates a touch slide event in response to a touch slide operation performed by a user by sliding from outside the projection window to inside the projection window, and when a start touch point of the touch slide operation is located in a target area, converts the touch slide event into an edge slide event of the source projection device, and then sends the edge slide event to the source projection device, where the target area is an area formed by extending a preset distance outward from an edge of the projection window; and the source projection device updates screen display content based on the edge slide event after receiving the edge slide event.

Abstract: A low-damage processing device for complex microstructure by hybrid laser-ultrasonic processing in a steady flow area belongs to the field of precision special processing technology, and the device includes: a base, a workpiece clamping sliding table unit, a laser unit, a jet gun unit and a host computer. The workpiece clamping sliding table unit, the laser unit and the jet gun unit are provided on the base. The laser is applied vertically to the surface of workpiece. The jet gun unit emits a high pressure water jet at an angle of 45 degrees to the surface of the workpiece. The base is provided with a waste liquid collection device. The water jet and the laser act on the workpiece surface at the same time. The present disclosure strips the recast layer of the processed surface in real time, and improves the processed quality and performance of workpiece.

Abstract: An application window projection method and an electronic device are provided. The method is applicable to a system including a first electronic device and a second electronic device. The method includes: The first electronic device establishes a connection to the second electronic device. The first electronic device projects a first window of an application onto the second electronic device. The second electronic device displays the first window. The first electronic device displays a second window of the application.

Abstract: The screen projection display method includes: After receiving screen projection request information sent by a source device, a target device obtains window data of an application enabled by the source device, where the window data includes display content corresponding to at least two windows opened in a same application enabled by the source device; and the target device displays the window data of the enabled application. The target device onto which a screen is to be projected obtains the window data of the application enabled by the source device. The window data not only includes content of a currently visible window on the source device, but also includes content of a window that is enabled by the source device but is invisible. The target device displays the window data on a display interface of the target device.
