The embodiment of the invention provides a method and device for achieving magnifying lens operation on a touch screen. The method and device are applied to an electronic device which has the magnifying lens functions and is provided with a touch screen. The method comprises the steps that input operation on the touch screen is acquired; whether the target object of the input operation is a magnifying lens or not is judged according to the input operation, and if yes, gesture judgment is conducted on the input operation, and a gesture judgment result is obtained; whether the input operation is processed by the magnified target object or not is judged according to the gesture judgment result, and if yes, the input operation is converted and the conversion result is transmitted to the magnified target object in an unvarnished mode; whether content is updated in a coordinate area corresponding to the transmitted and magnified target object or nor is judged, and if yes, the display content of the magnifying lens is updated. According to the method for achieving the magnifying lens operation on the touch screen, modes can be automatically selected. The embodiment of the invention further provides a host.
Description
technical field [0001] The invention relates to the field of data processing, and more specifically relates to a method, device and host for realizing a magnifying glass on a touch screen. Background technique [0002] With the rapid development of mobile platforms, people's dependence on mobile smart touch-screen terminals has begun to surpass that of PCs. Mobile smart terminals have abandoned the traditional keyboard and mouse input methods and adopted more humanized touch-screen input, which greatly simplifies and It is convenient for people to use it, so that people of all ages can use it without training. Moreover, with the continuous reform and progress of technology, the processing capability of mobile smart terminals has been continuously enhanced, which is already comparable to that of PCs. However, compared with PCs, mobile smart terminals are smaller, lighter and easier to carry. Although mobile smart terminals have many features and advantages, they are still un...
