If you want to use Python to develop a graphical interface, there are many tools to choose from, each with the pros and cons, previously used Wxpython+boa-constructor, has not been clear. New understanding of the next PyQt4, seems to use this person also more, so decided to start learning this. Version:pyqt-py2.7-x86-gpl-4.9.1-1.exe PyQt4 takes a QT designer and uses it to create an interface, layout controls such as Form,button,text, and so on, using

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
