Terms

widget-components, controls such as: Buttons, RadioButtons, text fields, frames, and text labels

frame-contains the rectangular region of the component, a rectangular area, can contain other widgets

Child, parent-When you create a component and put it into a frame, you create a parent-son relationship

2 form Layouts Layout management

Tkinter contains the layout in 3, the author strongly recommends using the grid layout, dividing the form's inner region into similar forms, and creating the component is only displayed in the form after it has been registered using layout mode.

2.1grid () method parameters

column--the number of columns of the control drop position, starting from 0, the default is 0;

clomnspan--setting the number of columns that the cell spans horizontally

in_--Reset W to the subform of the form W2, method: In_=w2.w2 must be the parent form subclass of W;

ipadx--sets the size of the X-direction white space within the control;

ipady--sets the size of the white space in the Y direction of the control;

padx--set the X-direction white space around the control to preserve the size;

pady--sets the size of the white space in the Y-direction around the control;

row--controls the number of rows placed, starting with 0, the default is the number of rows occupied by the previous bit

rowspan--sets the number of columns vertically spanned by the cell rowspan=4, columnspan=5);

sticky--set alignment, default to center

Sticky=tk.ne (upper right corner) tk.se (lower right) TK.SW (lower left) Tk. NW (upper left corner)

Sticky=tk. N (upper middle), Tk. E (middle right), Tk. S (lower middle), Tk. W (left middle).

Sticky=tk. N+tk. S centered and stretched vertically

Sticky=tk. E+tk. W Center and stretch horizontally

Sticky=tk. N+tk. E+tk. S+tk. W Stretch Fill table cell

2.2 Form Redraw

Use the grid layout to populate the component with the entire cell and redraw it as the size of the form changes
