construction Methods: Gauge (Parent,id,range=100,pos,size,style=ga_horizontal)Range refers to the value of an end point specified when the progress bar is loaded, and the program will confirm that the current progress bar should be more than full. The style specifies whether the load is loaded horizontally or vertically, and is loaded vertically ga_verticalUnlike some other components, it is not enough to construct the progress bar in the window alone, so the progress bar is static. The progres

parameters.• Data files store statistical information and are divided into two files: CSISS.DHT stores data index information, Csiss.dat stores data body information, in which the comment CS is the spatial sequence data, TS is the time series data, and CSTs is the spatiotemporal sequence data.• Weight file stores spatial weight information with the suffix named Gal. The number of first-action space entities in this file, starting from the second line, each two lines form a fixed format, such as
