C # Notes 9--multi-screen, full-screen program based on TableLayoutPanel

Recently, due to the need for work, you need to set up a multiple-screen window to facilitate multiple-screen playback of the video.
Thinking about it, the general idea is as follows: Use TableLayoutPanel to divide multiple regions, in each area, put a PictureBox, with PictureBox to receive the camera data flow;
Each time you select a different split screen, set the number of rows and columns of TableLayoutPanel according to the number n*n and add PictureBox to it.
Multi-screen effect diagram is as follows:

For multiple split screen, usually need full-screen function, mostly divided into full screen and program form full screen, its corresponding effect is as follows:

The code is as follows:
