"基于Qt的嵌入式终端记事本与电子相册设计与实现"

As the information industry continues to grow, embedded products have become increasingly mature, and everyday life demands higher practicality, aesthetics, and entertainment value from these products. A good human-machine interface is crucial in the design of handheld embedded products, and graphical user interfaces are essential for various embedded terminals. Notepad and electronic albums are basic products developed for embedded systems, and designing a visually appealing, feature-rich, and interactive notepad and electronic album using embedded terminals carries practical significance and value. The purpose of this paper is to design and implement a notepad and electronic album on an embedded terminal. The paper first introduces the advantages of Linux and Qt, then analyzes the programming mechanism of Qt in software development. Based on the characteristics of embedded terminal application, the paper conducts design requirements analysis, specific interface design, and overall structure design for the notepad and electronic album. This project realizes functions such as creating, opening, editing, saving, and saving as in the notepad, and features like zooming, rotating, browsing, forward, and backward in the electronic album.
