Cross-platform low-redundancy application software instant skin changing method and system

The invention discloses a cross-platform low-redundancy application software instant skin changing method and system. The method comprises the following steps: constructing a skin changing file tree; performing template transformation on the QSS file in the constructed skin change file tree to form a QSS template file; obtaining the name of the skin switched by the user, and reading a QSS template file in the transformed skin changing file tree; splicing a skin-based path according to the skin name information and the program running path, and performing replacement processing on information in the QSS template file based on the skin-based path; the new style information obtained after replacement is completed is applied to all the controls, and instant switching of the skin is achieved; the invention further discloses a cross-platform low-redundancy instant skin changing system for the application software. According to the method, the problems that in the software skin changing process, a large amount of co
