Python+opencv+tkinter Integrated Demo Because of the need to use OPENCV for small demo development, but because the OPENCV with the GUI function is still very simple, so use opencvv+tkinter combination implementation. First, the result chart. In the GUI click on the point of Praise button in the console can show "Someone to give you a little praise." Directly on the code: fromTkinterImport*ImportCv2 fr

Tkinter supports three kinds of geometry managers: Grid Manager, Package Manager, location ManagerTip: Because each manager has its own style of placing widgets, it is best not to use multiple managers in small artifacts in the same container. You can use the framework as a sub-container to get the desired layout.1.
