Thank the author a lot.

This article is modified according to a program in codeproject.

You can achieve this by dragging the mouse in the window. Really? Yes

Code:

A form. One class:

Form:

Effect:

Code:

Public partial class frm_movecontrol: FORM {private cls_movecontrol movecontrol; Public frm_movecontrol () {initializecomponent (); movecontrol = new cls_movecontrol (this); // This indicates a window, or a panel or other container movecontrol. applymove (button2); movecontrol. applymove (button3, cls_movecontrol.movedirection.vertical); movecontrol. applymove (button1, Panel1, cls_movecontrol.movedirection.any );}}

Next is the class for mobile controls:

Using system; using system. collections. generic; using system. drawing; using system. text; using system. windows. forms; namespace cachedemo1 {class cls_movecontrol {public Enum movedirection {Any, horizontal, vertical} private int detail = 200; private int int_frmheight = 200; Public int int_frmwidth {get {return detail ;} set {int_frmwidth = value ;}} public int int_frmheight {get {return int_frmh Eight;} set {int_frmheight = value;} public cls_movecontrol (INT width, int height) {this.int _ frmwidth = width; this.int _ frmheight = height ;} // if only the window is passed in, you can use form. Of course, you can also use the control class, because form is also sent to the control class public cls_movecontrol (control FRM) {this.int _ frmwidth = FRM. clientrectangle. width; this.int _ frmheight = FRM. clientrectangle. height; frm. resize + = delegate (Object sender, eventargs e) {this.int _ frmwidth = FRM. clientrectangle. width; this.int _ frmheight = FRM. clientrectangle. height;}/** frm. clientrectangle. width; the reason why clientrectangle is used here * Because clientrectangle can obtain the available area of the window * The height of the title bar of the window can be removed. * The advantage of control is that form can be passed in. You can also wear container controls, such as panel */Public void applymove (Control) {applymove (control, movedirection. any);} public void applymove (Control, movedirection) {applymove (control, control, movedirection);} public void applymove (control, control container, movedirection) {bool isdrag = false; point dragstartpoint = point. empty; control. mousedown + = delegate (Object sender, Mouseeventargs e) {isdrag = true; dragstartpoint = new point (e. x, E. y); control. cursor = cursors. sizeall; control. capture = true;}; control. mouseup + = delegate (Object sender, mouseeventargs e) {isdrag = false; control. cursor = cursors. default; control. capture = false;}; control. mousemove + = delegate (Object sender, mouseeventargs e) {If (isdrag) // true only when the mouse is pressed. Once the mouse is opened, the value is false {// The value can only be moved horizontally. Vertical movement can only be vertical movement. // Any direction can be moved if (movedirection! = Movedirection. vertical) // horizontal and any can enter {int left = container. left + E. x-dragstartpoint. x; // container. left = math. max (0, left); // do not exceed the left boundary container. left = getmiddlevalue (left, container. width, this.int _ frmwidth);} If (movedirection! = Movedirection. horizontal) {int Top = container. top + E. y-dragstartpoint. y; // container. top = math. max (0, top); container. top = getmiddlevalue (top, container. height, this.int _ frmheight );}}};} /// <summary> // do not control the dragged control beyond the window. // </Summary> /// <Param name = "Val"> </param> // /<Param name = "containerwoh"> </param> // <Param name = "frmwidth"> </param> // <returns> </returns> private int getmiddlevalue (INT Val, int containerwoh, int frmwoh) {int min = 0; int max = frmwoh-containerwoh; If (Val <min) {val = min;} If (Val> MAX) {val = max;} console. writeline (VAL); Return Val ;}}}
