Problems solved by technology

However, limited by the size of the handheld communication device itself, if you want to use a hierarchical display method to display functional options on its limited screen space, you must reduce the size of the options
However, if the font or icon of the option is too small, it is easy for the user to touch other options by mistake, or the user cannot see the content of the option clearly

Abstract

The invention discloses a display method for a tree data structure and a handheld electronic device. The tree data structure comprises a node object and a sub-object, wherein the sub-object belongs to the node object. The handheld electronic device comprises a menu providing module, a label providing module, an input module and a display module. The method for constructing a menu interface comprises the following steps: firstly, displaying an object row comprising the sub-object and a label object on an operating screen; secondly, arranging the node object and the sub-object into the object row; and thirdly, moving the label object, wherein when the label object approaches the sub-object, the name of the node object is displayed on the operating screen.

Description

technical field [0001] The present invention relates to a hand-held electronic device and a display method of a tree-like data structure, in particular to a hand-held electronic device with a screen and a display method of a tree-like data structure. Background technique [0002] With the rapid development of science and technology and economy, various handheld electronic devices have been widely used in human life, among which handheld communication devices have the most profound impact on human life. In order to meet people's needs, these handheld communication devices have become smaller and smaller in size and have more and more functions. Taking handheld communication devices such as PDA mobile phones and smart phones as examples, they not only have various functions of traditional communication devices, but also allow users to write documents through their built-in operating systems. , sending and receiving emails, browsing the Internet, or using instant messaging sof...
