scenario 1: set resizable to false

mainWindow = new BrowserWindow({
    height: 563,
    width: 1400,
    resizable: false
  })

scenario 2: set the program to be frameless, and then write the window operation code yourself

mainWindow = new BrowserWindow({
    height: 563,
    width: 1400,
    frame: false
  })

in the render process require ('web-frame'). SetZoomLevelLimits (1,1);

the first method has no effect, after dragging, this property has no effect,
the second is useless,

is set to have no border, and then you need css to drag, and then cause a double click to enlarge, and then you don't know how to disable

mainWindow = new BrowserWindow({
    //
    resizable: false
  })
