How to create an XNA textbox

• You can download source code here!

Introduction 

As there was no text box in the XNA environment I was forced to create a text box by myself, and wanted to share the solution here for programmers.

Using the Code 

First think that we need to draw our text, so what do we need to wrap text in a rectangle? Below is my source code to wrap text in a rectangle by width. So the spirtfont is for measurement purposes, text is what you want to wrap in the textbox, and maxLineWidth is the parameter for the width of the TextBox.

let's first define some structs: 

public struct Text
{
    public int key;
    public string myText;
    public int FontSize;
    public Rectangle rect;
    public Color mycolor;
    public string strplaceOfUse;
    public bool ShouldItBeShownInThisScreen;
    public string wrappedString;
    public int HorizontalMargin;
    public string Action;
    public bool isFocused;
}
public struct mylist
{
    public string mystring;
    public int key;
}

Let's create a function to load fonts:

//
public SpriteFont fncGivemeFont(int fontsize)
{
    string BaseDirectory = ".";
    SpriteFont myfont=null;
    switch (fontsize)
    {
        case 14:
        {
            myfont = content.Load<SpriteFont>(BaseDirectory + "\\Font\\myfont14");
            break;
        }
        case 16:
        {
            myfont = content.Load<SpriteFont>(BaseDirectory + "\\Font\\myfont16");
            break;
        }
        case 18:
        {
            myfont = content.Load<SpriteFont>(BaseDirectory + "\\Font\\myfont18");
            break;
        }
        case 20:
        {
            myfont = content.Load<SpriteFont>(BaseDirectory + "\\Font\\myfont20");
            break;
        }
        case 22:
        {
            myfont = content.Load<SpriteFont>(BaseDirectory + "\\Font\\myfont22");
            break;
        }
        default:
        {
            myfont = content.Load<SpriteFont>(BaseDirectory + "\\Font\\myfont14");
            break;
        }
    }
    return myfont;
}

Now we initialize our text:

//mytext
mytext.key = 0;
mytext.HorizontalMargin = 50;
mytext.mycolor = Color.Blue;
mytext.rect = new Rectangle((WindowsScreenWidth - 1000) / 2 + mytext.HorizontalMargin, 
  (WindowsScreenHeight - 300) / 2 + 50, 1000 - 1 * mytext.HorizontalMargin, 300);
mytext.strplaceOfUse = "AddNewWords_Word";
mytext.ShouldItBeShownInThisScreen = false;
mytext.myText = "";
mytext.FontSize = 22;
mytext.wrappedString = WrapText(fncGivemeFont(mytext.FontSize), mytext.myText, mytext.rect.Width);
mytext.Action="TextBox";
mytext.isFocused=true;
//ArrayList=>MyTexts
myTexts[0] = mytext;

The output of this function is another string, however it has a \n to do our wrap in it.

public static string WrapText(SpriteFont spriteFont, string text, float maxLineWidth)
{
    string[] words = text.Split(' ');
    StringBuilder sb = new StringBuilder();
    //
    ArrayList MyFormattedWords=new ArrayList();
    int currentkey=0;
    //
    float lineWidth = 0f;

    float spaceWidth = spriteFont.MeasureString(" ").X;
    Vector2 ResidueSize = Vector2.Zero;
    foreach (string word in words)
    {
        Vector2 size = spriteFont.MeasureString(word);
        if (size.X > maxLineWidth)
        {

            string tempstr1 = "";
            int EndIndexOfSplittedWord = 0;
            ArrayList mystringList = new ArrayList();
            int SplittedWordIndex = 0;
            int StartIndexOfSplittedWord = 0;
            for (int i = 0; i < word.Length; i++)
            {
                tempstr1 += word[i];
                Vector2 mytempstrsize = spriteFont.MeasureString(tempstr1);
                if (mytempstrsize.X >= maxLineWidth)
                {
                    EndIndexOfSplittedWord = i - 1;
                    mylist objstring = new mylist();
                    objstring.mystring = "";
                    SplittedWordIndex++;
                    objstring.key = SplittedWordIndex;
                    for (int j = StartIndexOfSplittedWord; j < EndIndexOfSplittedWord; j++)
                    {
                        objstring.mystring += word[j].ToString();
                    }
                    mystringList.Add(objstring);
                    tempstr1 = word[i].ToString();
                    StartIndexOfSplittedWord = i;
                    if (i == word.Length - 1)
                    {
                        mylist objstring2 = new mylist();
                        objstring2.mystring = tempstr1;
                        SplittedWordIndex++;
                        objstring2.key = SplittedWordIndex;
                        mystringList.Add(objstring2);
                    }
                }
                else if (!(mytempstrsize.X >= maxLineWidth))
                {
                    if (i == word.Length - 1)
                    {
                        mylist objstring3 = new mylist();
                        objstring3.mystring = tempstr1;
                        SplittedWordIndex++;
                        objstring3.key = SplittedWordIndex;
                        mystringList.Add(objstring3);
                    }
                }
            }
             //
            string mystr = "";
            for (int i = 1; i <= SplittedWordIndex; i++)
            {
                foreach (mylist objlist in mystringList)
                {
                    if (objlist.key == i)
                    {
                        currentkey++;
                        mylist formattedobjlist;
                        formattedobjlist.key=currentkey;
                        formattedobjlist.mystring=objlist.mystring;
                       MyFormattedWords.Add(formattedobjlist);
                    }
                }
            }
            sb.Append(mystr);
        }
        else
        {
            currentkey++;
            mylist formattedobjlist;
            formattedobjlist.key = currentkey;
            formattedobjlist.mystring = word;
            MyFormattedWords.Add(formattedobjlist);
        }
    }
    for (int i=1;i<=currentkey;i++)
    {
        foreach (mylist wordx in MyFormattedWords)
        {
            if (i == wordx.key)
            {
                Vector2 size = spriteFont.MeasureString(wordx.mystring);

                if (lineWidth + size.X < maxLineWidth)
                {
                    sb.Append(wordx.mystring + " ");
                    lineWidth += size.X + spaceWidth;
                }

                }
            }
        }
    }
    return sb.ToString();
}  

So now we create our wrap function. We should get the input from the user, how do we do it? Here is the code: 

First we need a class to define our parameters of the keys and stuff: Let's name the class clsInput:

        public string ZKeyState = "none";
        public string SpaceKeyState = "none";
        public string BackKeyState = "none";
        /// //////////////////////////////////////////////

            foreach (Keys key in mykeys)
            {
                if (key == Keys.LeftShift || key == Keys.RightShift)
                {
                    result = true;
                }
            }
            return result;
        }
        public bool isControlPressed(Keys[] mykeys)
        {
            bool result = false;

            }
            return result;

    }
}

Great, now we code for getting the keyboard input from the user:

string keyboardString = "";
clsInput myclsinput = new clsInput();

{
    if(IsGettingStringFromUseron)
    {
        Keys[] mykeys=myKeyboardState.GetPressedKeys();
        bool isShift = myclsinput.isShiftPressed(mykeys);
        bool isControl = myclsinput.isControlPressed(mykeys);
        if (myKeyboardState.IsKeyDown(Keys.A))
        {
            if (myclsinput.AKeyState == "none") myclsinput.AKeyState = "down";

So this would be our function to get the keyboard state and keys from the user.

Now let's draw our string on a rectangle:

public void DrawTexts(SpriteBatch mybatch)
{
    for (int i = 0; i < myTexts.Length; i++)
    {
        if (myTexts[i].ShouldItBeShownInThisScreen)
        {
            mybatch.DrawString(fncGivemeFont(myTexts[i].FontSize), 
              myTexts[i].wrappedString, 
              new Vector2(myTexts[i].rect.Left,myTexts[i].rect.Top),
              myTexts[i].mycolor);
        }
    }
}

Points of Interest

Well, wrapping a text will get you a complete day, so I recommend you to recommend Microsoft to create some stuff like textbox for XNA and make it easier to work with this great technology for programmers. I really suggest you have a look at the wrapper function and make it more perfect. I worked  a day on it, you can put half a day and make it useful for any font and any height of a rectangle.

If there may be any updates, you may get it here, don't go elsewhere. Thanks for reading my article. Love all coders <3.
