+Summary: Form ClientRectangle.Size Ignores Menu and Scroll bar.
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+With .NET the ClientRectangle.Size does not subtract the Menu bar or the
+Scrollbar area of the form.
+
+The following program with a Menu and a Scroll bar can be used to
+illustrate the problem:
+
+using System;
+
+using System.Drawing;
+
+using System.Collections;
+
+using System.ComponentModel;
+
+using System.Windows.Forms;
+
+using System.Data;
+
+
+
+namespace WinScreenArea
+
+{
+
+ /// &lt;summary&gt;
+
+ /// Summary description for Form1.
+
+ /// &lt;/summary&gt;
+
+ public class Form1 : System.Windows.Forms.Form
+
+ {
+
+ private System.Windows.Forms.MainMenu mainMenu1;
+
+ private System.Windows.Forms.MenuItem menuItem1;
+
+ private System.Windows.Forms.MenuItem menuItem2;
+
+ private System.Windows.Forms.MenuItem menuItem3;
+
+ private System.Windows.Forms.Label label1;
+
+ /// &lt;summary&gt;
+
+ /// Required designer variable.
+
+ /// &lt;/summary&gt;
+
+ private System.ComponentModel.Container components = null;
+
+
+
+ public Form1()
+
+ {
+
+ //
+
+ // Required for Windows Form Designer support
+
+ //
+
+ InitializeComponent();
+
+
+
+ //
+
+ // TODO: Add any constructor code after InitializeComponent call
+
+ //
+
+ }
+
+
+
+ /// &lt;summary&gt;
+
+ /// Clean up any resources being used.
+
+ /// &lt;/summary&gt;
+
+ protected override void Dispose( bool disposing )
+
+ {
+
+ if( disposing )
+
+ {
+
+ if (components != null)
+
+ {
+
+ components.Dispose();
+
+ }
+
+ }
+
+ base.Dispose( disposing );
+
+ }
+
+
+
+ #region Windows Form Designer generated code
+
+ /// &lt;summary&gt;
+
+ /// Required method for Designer support - do not modify
+
+ /// the contents of this method with the code editor.
+
+ /// &lt;/summary&gt;
+
+ private void InitializeComponent()
+
+ {
+
+ this.mainMenu1 = new System.Windows.Forms.MainMenu();
+
+ this.menuItem1 = new System.Windows.Forms.MenuItem();
+
+ this.menuItem2 = new System.Windows.Forms.MenuItem();

+
+ this.menuItem3});
+
+ //
+
+ // menuItem1
+
+ //
+
+ this.menuItem1.Index = 0;
+
+ this.menuItem1.MenuItems.AddRange(new System.Windows.Forms.MenuItem[] {
+
+ this.menuItem2});
+
+ this.menuItem1.Text = &quot;Menu1&quot;;
+
+ //
+
+ // menuItem2
+
+ //
+
+ this.menuItem2.Index = 0;
+
+ this.menuItem2.Text = &quot;MenuItem2&quot;;
+
+ //

+
+ this.label1.Name = &quot;label1&quot;;
+

+
+ this.label1.TabIndex = 0;
+
+ this.label1.Text = &quot;Label to force scollbar&quot;;
+

+

+

+ Cursor GetLocationCursor(int x,int y)
+
+ {
+
+ // returns the cursor type needed based on the location
+
+ // of the cursor. If the cursor is at least 50 pixels inside
+
+ // any edge of the ClientRectangle the desired cursor is
+
+ // the default cursor, otherwise it is one of the four
+
+ // arrow cursors.
+
+ int xMin,xMax,yMin,yMax;
+
+ xMin=this.ClientRectangle.Left+cursorMargin;
+
+ xMax=this.ClientRectangle.Right-cursorMargin;
+
+ yMin=this.ClientRectangle.Location.Y+cursorMargin; // positive Y is down.
+
+ yMax=this.ClientRectangle.Size.Height-cursorMargin;
+
+ if (y&lt;yMin)
+
+ {
+
+ return Cursors.IBeam;
+
+ }
+
+ else if(y&gt;yMax)
+
+ {
+
+ return Cursors.IBeam;
+
+ }
+
+ if (x&lt;=xMin)
+
+ {
+
+ return Cursors.IBeam;
+
+ }
+
+ else if(x&gt;xMax)
+
+ {
+
+ return Cursors.IBeam;
+
+ }
+
+ return Cursors.Default;
+
+
+
+ }
+
+
+
+ private void Form1_MouseMove(object sender,
+System.Windows.Forms.MouseEventArgs e)
+
+ {
+
+ if (this.Cursor != Cursors.WaitCursor)
+
+ {
+
+ this.Cursor=GetLocationCursor(e.X,e.Y);
+
+ }
+
+
+
+ }
+
+ }
+
+}
+
+
+
+Steps to reproduce the problem:
+1. Compile and execute the program.
+2. Using the Mouse, move the cursor around the screen. When you get within
+50 pixels of any border of the form the cursor will change to an IBeam.
+When you get to the end of the ClientRectangle area the cursor will change
+ back to an arrow.
+
+With .Net this will happen if you cross the menu bar on the top, or the
+Scroll bar on the right of the form. With Mono the IBar remains to the end
+of the Form, ignoring the menu bar and the scroll bar.
+3.
+
+Actual Results:
+Ibeam cursor does not change to an arrow when above the menu bar, or to the
+right of the scroll bar.
+
+Expected Results:
+Ibeam cursor should change to an Arrow when cursor is above the bottom of
+the menu bar, and to the right of the left most edge of the scroll bar.
+
+How often does this happen?
+Always
+
+Additional Information:
+
+Mono is from SVN
