Embodiment Construction

[0022] figure 1 A schematic structural diagram of a system for completing calculations using WPF technology according to the first embodiment of the present invention is shown. Specifically, in this embodiment, the calculator 4 includes a display device 1, an input device 3, and a calculation control device 2, wherein the input device 3 includes a key hiding device 31, wherein the key hiding device 31 uses to hide buttons that are not used frequently. Those skilled in the art understand that with the increase of computer functions, the number of keys (such as virtual keys matched with the touch screen) is very large, and if displayed on the same page, it will appear extremely cluttered, and due to the limited display area of ​​the display device, The area of ​​each button can only be designed to be relatively small, which brings great difficulties to the user for quickly locating and pressing the button. Therefore, in this embodiment, the calculator 4 hides infrequently use...

Abstract

The invention provides a system for finishing calculation by windows presentation foundation (WPF) technology. The system comprises a display device, an input device and a calculation control device, wherein the input device comprises a key hiding device for hiding keys which are not frequently used. In a computer, tab page nesting and button switching are used for realizing a convenient and practical user interface; the problem of data reutilization is solved by methods such as double-click drag, hot keys and the like; and a runtime error caused by data overflow is avoided by limiting input data from a definitional domain. The core idea of the computer provided by the invention is centered on humanization, high interactivity, practicability and usability, so an effort is made to improve the working efficiency of people and reduce repeated and complex labor to really meet humanized requirements.

Description

technical field [0001] The invention relates to a calculator, in particular to the humanized design of the input, display and fault-tolerant functions of the calculator, in particular to a system for completing calculation by using WPF technology. Background technique [0002] With the continuous development of science and technology, calculators are increasingly integrated into people's lives. When people have problems, they can turn to calculators for help, and calculators, a powerful tool, should be properly utilized to improve work efficiency. For a calculator, the simplest function is calculation. People may encounter some problems such as: calculating mortgages, compound interest, or some problems involving statistics, which can be solved by using a calculator. To solve this problem, only one convenient and easy-to-use calculator. However, some of the current calculators cannot meet people's needs, or although there is no shortage of powerful functions, the operation...
