Tkinter Module Common parameters (Python3)

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:
Import Tkinter
Root=tkinter. Tk () #生成root主窗口
Label=tkinter. Label (root,text= ' Hello,gui ') #生成标签
Label.pack () #将标签添加到主窗口
Button1=tkinter. Button (root,text= ' Button1 ') #生成button1
Button1.pack (Side=tkinter. left) #将button1添加到root主窗口
Button2=tkinter. Button (root,text= ' Button2 ')
Button2.pack (Side=tkinter. right)
Root.mainloop () #进入消息循环 (required component)

3.15 Core components in Tkinter:
button buttons;
A canvas drawing component in which graphics can be drawn;
Checkbutton check box;
Entry text box (single line);
Text textbox (multiple lines);
Frame frame, which sets up a set of several components
A label tag that can display text or pictures;
Lisbox list box;
menu menus;
Menubutton its functions can be completely replaced with the menu;
The Message is similar to the label component, but can wrap text according to its size;
Radiobutton Radio Box;
Scale slider, allowing a numeric value to be set by the slider
Scrollbar scroll bar; Use the standard scroll bar of the canvas, entry, ListBox, and text widgets;
The toplevel is used to create a subwindow window component.
(In Tkinter, the window part class has no rating; all widgets are brothers in the tree.) ）

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 assembly, top-aligned ' n ', bottom-aligned ' s ', left ' W ', right ' e '
Side: The position of the component in the main window can be ' top ', ' bottom ', ' left ', ' right ' (tkinter when used.) Top,tkinter. E);
Fill Filling method (Y, vertical, X, horizontal)
Expand 1 Extensible, 0 non-extensible
The grid component uses the row and column method to place the component's position, with the parameters:
Column: The starting position of the columns where the component is located;
Columnspam: The column width of the component;
Row: The starting position of the line where the component is located;
Rowspam: The line width of the component;
The place component can use coordinates to position components directly, with parameters such as:
Anchor: alignment of components;
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 x-coordinate of the component relative to the window, which should be a decimal between 0-1;
Rely: The component's y-coordinate relative to the window, which should be a decimal between 0-1;
Width: The widths of the components;
HEITHT: The height of the component;
Relwidth: The width of the component relative to the window, 0-1;
Relheight: The height of the component relative to the window, 0-1;

5, use Tkinter. Control button Parameters when button:
Anchor: Specifies the position of the text on the button;

Height: Specifies the level of the button;
Image: Specifies the picture displayed on the button;
State: Specifies the status of the button (disabled);
Text: Specifies that the button is displayed;
Width: Specify a button's widths
PADX sets the distance between the text and the button border X, as well as the pady;
Activeforeground the foreground color when pressed
Textvariable variable text, used in conjunction with STRINGVAR, etc.

9. Group Canvas control Parameters:
Background (BG) background color;
Foreground (FG) foreground color;
BorderWidth component Border width;
width of the component;
Height altitude;
Bitmap bitmap;
Image Image;
The main methods of drawing are as follows:
Create_arc arc;
Create_bitmap draw bitmap, support XBM;
Create_image draw picture, support GIF (x,y,image,anchor);
Create_line draw the spur line;
Create_oval; Draw an ellipse;
Create_polygon Draw polygons (coordinates are listed in order, without parentheses, and parameters, Fill,outline);
Create_rectangle Draws the rectangle ((a,b,c,d), the value is the upper-left corner and the lower-right corner of the coordinates);
Create_text drawing text (font parameter fonts,);

Itemconfig Modify the graphic properties, the first parameter is the ID of the graph, and the parameter that you want to modify is behind;
Move Moving Image (1,4,0), 1 is an Image object, 4 is the Traverse 4 pixels, 0 is a longitudinal pixel, and then with Root.update () refresh can see the movement of the image, in order to make multiple movements become visible, preferably with time.sleep () function;
As long as you draw a graph with the Create_ method, you automatically return an ID, assign it to a variable when creating a graph, and use the variable name when you need an ID.
Coords (ID) returns the two coordinates (4 numeric tuples) of the position of the object;

For button components, menu components, and so on, you can specify their event handlers through the command parameter when you create a component. method is bind, or the Bind_class method is used for class binding, and the Bind_all method binds all component events to the event response function.
