The TextEdit of QML

TextEdit Displays an editable, formatted text box. It can also display plaintext and rich text. For example:
TextEdit {
width:240
Text: "<b>Hello</b> <i>World!</i>"
font.family: "Helvetica"
Font.pointsize:20
Color: "Blue"
Focus:true
}

Set focus to True to allow TextEdit to accept keyboard focus.
Note: The text edit box does not implement scrolling, cursor manipulation, and other behaviors that are specific to the senses. For example, add flickable scroll to follow the cursor:
flickable {
Id:flick

width:300; height:200;
ContentWidth:edit.paintedWidth
ContentHeight:edit.paintedHeight
Clip:true

function EnsureVisible (R)
{
if (ContentX >= r.x)
ContentX = r.x;
else if (contentx+width <= r.x+r.width)
ContentX = R.x+r.width-width;
if (Contenty >= r.y)
Contenty = R.Y;
else if (contenty+height <= r.y+r.height)
Contenty = R.y+r.height-height;
}

TextEdit {
Id:edit
Width:flick.width
Height:flick.height
Focus:true
WrapMode:TextEdit.Wrap
OnCursorRectangleChanged:flick.ensureVisible (Cursorrectangle)
}
}
A particular sensory may use smooth scrolling (for example, using smoothedanimation), possibly another visible scrollbar, or a scroll bar that fades to the display, and so on.
Clipboard support can provide cut (), copy (), paste () functions, selection can rely on settings selectbymouse to handle various kinds of information in the traditional mouse mechanism. Complete processing is accomplished by setting the starting position and terminating position, or using SelectAll () or Selectword ();
You can convert between the cursor position and the pixel point by Positionat () and Positiontorectangle ().
