Let’s compare the DelphiVCL form with other Python GUI frameworks (we take the GUI created in this post as an example):

DelphiVCL provides better OS integration and styling by default. It provides Windows-10 styling to make your GUI looks professional and up-to-date.

DelphiVCL even provides Windows right-click functionality by default. Compared with PyQt that lacks OS integrations and Tkinter that does not provide the right-click menu by default.
