C # Form controls automatically adjust following form size

Test purpose: How to make the controls in the window automatically adjust to the size of the form

Test environment: WIN10 ENT + VS2015

Method principle: Record the initial window size, control size and other information. Whenever the window size changes, the window size is calculated relative to the initial scale, and then the position (location), size, and font size (font.size) of the control are adjusted based on the scale.

C # main test code:

using system;using system.drawing;using system.windows.forms;namespace test1111{     public partial class Form1 : Form    {         int igformwidth = new int ();   //window width         int igformheight = new int ();  //window height         float fgwidthscaling = new float ();  / /width Scaling         float fgheightscaling = new float () ;  //Height scale         public form1 ()          {             InitializeComponent ();             igformwidth  = this. width;            igformheight = this. Height;            initcontag (This);         }        private void  Form1_Load (object sender, eventargs e)         {         }        private void  form1_resize (object sender, eventargs e)         {             if  (igformwidth == 0  | |  igformheight == 0)  return;             fgWidthScaling =  (float) this. width /  (float) igformwidth;            fgheightscaling =  (float) this. height /  (float) igformheight;             resizecon (fgwidthscaling, fgheightscaling, this);         }                // Records the initial   position, size, font size information for the control set         private void initcontag ( Control cons)         {             foreach  (control con in cons. Controls)  //traversal control set             {                 con. Tag = con. left +  ","  + con. top +  ","  + con. width +  ","  + con. height +  ","  + con. Font.size;                if   (Con. controls.count > 0)  //Handling child controls                  {                     initcontag (Con);                 }             }        }                 //Resize   Position, size, font size          private void resizecon (Float widthscaling, float heightscaling,  control cons)         {    &nbsP;       float ftmp = new float ();             foreach  (control con in cons. Controls)  //traversal control set             {                 string[] conTag  = con. Tag.tostring (). Split (new char[] {', '});                 ftmp = convert.tosingle (contag[0])  * widthScaling;                 con. left =  (int) ftmp;                 ftmp = convert.tosingle (contag[1])  * heightScaling;                  con. top =  (int) ftmp;                 ftmp = convert.tosingle (contag[2])  * widthScaling;                 con. width =  (int) ftmp;                 ftmp = convert.tosingle (contag[3])  * heightScaling;                 con. height =  (int) ftmp;                 ftmp = convert.tosingle (Contag[4])  * widthScaling *  heightscaling;                 Con. Font = new font ("",  ftmp);                if  (Con. controls.count > 0)  //Handling child controls                  {                     resizecon (Widthscaling, heightscaling, con);                 }             }        }     }}

To run the initial diagram:

650) this.width=650; "Src=" Https://s4.51cto.com/oss/201711/11/8460ef1492be77d33e48ab9c01e8e97f.png-wh_500x0-wm_3 -wmp_4-s_1597195286.png "title=" Img_01.png "alt=" 8460ef1492be77d33e48ab9c01e8e97f.png-wh_ "/>

Window resizing after Image:

650) this.width=650; "Src=" Https://s5.51cto.com/oss/201711/11/7ba30d431d6dee9d0584f43be9ceecf3.png-wh_500x0-wm_3 -wmp_4-s_4294428054.png "title=" Img_02.png "alt=" 7ba30d431d6dee9d0584f43be9ceecf3.png-wh_ "/>

You can see that when the size of the form changes, the position, size, and font size of the controls in the body have changed slightly.
