1, use Tkinter. Tk () generates the main window (Root=tkinter. Tk ());
Root.title (' title name ') modifies the name of the box body, or it can be named with the classname parameter when it is created;
Root.resizable (0,0) frame size adjustable, respectively, to indicate the variability of x, y direction;
Root.geometry (' 250x150 ') specifies the size of the main frame body;
Root.quit () exit;
Root.update_idletasks ()
Root.update () refresh the page;

2. Primary Sample:

1 Import tkinter2 Root=tkinter. Tk () #生成root主窗口3 label=tkinter. Label (root,text= ' Hello,gui ') #生成标签4 label.pack ()        #将标签添加到主窗口5 button1=tkinter. Button (root,text= ' Button1 ') #生成button16 button1.pack (side=tkinter. left)         #将button1添加到root主窗口7 Button2=tkinter. Button (root,text= ' Button2 ') 8 Button2.pack (Side=tkinter. right) 9 Root.mainloop ()             #进入消息循环 (required component)

4. Placement and layout of components (Pack,grid,place)

The pack component sets the Location property parameter:    after: The    component is placed after another component,    before:    before the component is placed in another component    , Anchor: Alignment of the  component, top-aligned ' n ', Bottom-aligned ' s ', left ' W ', and Right ' E '    side: The    component's position in the main window, can be ' top ', ' bottom ', ' ieft ', ' R ' (Tkinter when used. Top,tkinter. E);    fill            fill mode (Y, vertical, X, horizontal)    expand          1 Extensible, 0 non-extensible grid components use the row and column method to place the component's position, with the parameters:    column:         The starting position of the column where the component is located; Columnspam: Column width of the component     ; row: The      starting position of the row where the component is located;    rowspam:    line width of the component Place components can be placed directly using coordinates, parameters are:    Anchor: component alignment    ;    x: The        x-coordinate of the upper-left corner of the component;    y:   the y-coordinate of the upper-right corner of the component;    RELX: The         component's x-coordinate relative to the window, which should be a decimal between 0-1,    rely: The           component's y-coordinate relative to the window, a decimal between 0-1, and width    :          the component's breadth;    HEITHT: The   height of the component;    relwidth: The       component is relative to the width of the window, 0-1;    relheight:    The height of the component relative to the window, 0-1;
