Pack

• Introduced:
  • The pack Geometry Manager packs widgets by row or column. You can control this geometry manager with options such as fill Fill, expand Expand, and pull-over side.
  • The form of the pack's emission controls is like putting a control in the same size from top to down
  • The window default size is exactly the size of all controls when the window is not set to size and the pack is used for layout
  • Controls that are added by default are centered and occupy the entire row
• Common parameters:
  • Fill: Fills the space assigned to the control, fill:x to fill the x-axis direction, y for y-axis, and both to X+y
  • Expand: First, according to the normal standard to specify the size of the control, if the back window is left space, then will be assigned to those expand=true control, is two different sizes of buttons, 2expand=true, when using expand=true, side will not take effect!
  • Side: Side the value Left,right,top,bottom by making the control side-by in the specified direction of the window.
  • Anchor: Alignment, desirable value "n", "S", "W", "E", "NW", "SW", "se", "ne", "center" (Default is "center")
  • IPADX, Ipady: Inner margin
  • Padx,pady: Outer margin
• Applicable: Pack has some limitations compared to gird, but it is much easier to use in some but very common situations:
  • Place a widget into a frame (or any other container widget) and have it fill the entire frame
  • Put multiple widgets together
  • Place some widgets side-by
• Add:
  • Common functions:
    • pack_propagate (flag): The size of the window when the window is used to configure the pack control, and when flag=0, the window size will no longer just wrap all the controls, when the height and width settings of the window can take effect
    • Pack_forget (): Remove the control but not destroy it, you can use pack or another way to display
    • Pack_info (): Returns the value of the option provided by the pack.
    • Pack_slaves (): Returns all child component objects of this component in a list.

Grid

• Description: Grid is the meaning of the grid, the grid can be placed in block-style control.
• Common parameters:
  • Row: line number to distinguish whether different controls are in the same row
  • Column number to distinguish whether different controls are in the same column
  • Sticky: Determines the snapping direction of the control, which takes one or more values from the set n,s,e,w [cardinal meaning]. For example, to align the label to the left border, you can use W (West)
  • RowSpan: Row span, which determines the number of rows that a control occupies, the default row
  • ColumnSpan: column span, which determines the number of columns a control occupies, the default column
  • IPADX, Ipady: Inner margin
  • Padx,pady: Outer margin
• Applicable situation:
  • Especially handy when designing dialog boxes.
  • When the block is placed
• Add:
  • Common functions:
    • Grid_forget: Removing the control but not destroying it, you can use grid or another way to show [Grid_remove has the same effect]

    • Grid_propagete: When the window is resized by the window to configure the pack control, when flag=0, the window size will no longer just wrap all the controls, when the height and width settings of the window can take effect

    • Grid_slaves (): Returns all child component objects of this component in a list.

Place

• Description: The control can be placed using an absolute position or relative position.
• Common parameters:
  • X: The x-coordinate of the control in the window
  • Y: the y-coordinate of the control in the window
  • Relx,rely: The relative position of the main window, such as
  • Relwidth,relheight: Relative size, such as height=0.5,width=0.5, when the control occupies the One-fourth size of the window
• Applicable situation:
  • Customizing display methods
  • Position the button in the dialog box
• Add:
  • Common functions:
    • Place_forget (): Removes the control, but does not destroy it, you can use place again or another way to display
    • Place_slaves (): Returns all child component objects of this component in a list. [Slaves () has the same function]
    • Place_info (): Returns the value corresponding to the option provided by place.
