Thread: How to shift a String in a rectangle which is type of Canvas

Hi,
I had create a rectangle in Canvas like the textfield and now I can print my input in that rectangle, I want that how can I write the input when it's size is bigger than the rectangle! I want that when it's size is bigger than the rectangle the remain of my input must be shown and the input which I wrote earlier must be shifted! actualy I want to scroll my input in the rctangle, How can I do it? Could anyone show me sample code for it please?
to scrolling the input in the rectangle I worte some code like below but when i scroll the input with Canvas.Right the String which I inserted after scrolling will be seprated to characters! Could you help me to solve it please?How could I shift the String when I click on Canvas.Right?

public void copyStr(){
 
tchar=this.text.toCharArray();
copy=text.length()-1;
textchar[cp]=tchar[copy];
t[p]=textchar[cp];
cp++;
p++;
if(text.length()>=9){
 
shiftRight();
 
}
}
public void shiftRight(){
int m=0;
String temp;
char []te;
for (int i=10;i<this.text.length()-1;i++){
t[i-1]=t[i];
}
for(int i=10;i<this.text.length()-1;i++){
textchar[m]=t[i];
m++;
}
text=new String(textchar);
}
 
protected void keyPressed(int keyCode)
{
if(keyCode==-4){
shiftRight();
}
 
long currentTime = System.currentTimeMillis();
int pressedKeyNum = getNum(keyCode);
if( pressedKeyNum >= 0 && pressedKeyNum <= 9 ) {
if(keyCode == this.lastKeyStroke && currentTime - this.lastKeyStrokeTime < MIN_STROKE_TIME)
{
cursorplace++;
cursor[cursorplace]='_';
this.text = this.text.substring(0, this.text.length() - 1);
this.text += KEY_MAP[pressedKeyNum][this.lastKeyStrokeIndex];
this.lastKeyStrokeIndex++;
copyStr();
}
 
else
{
this.text += KEY_MAP[pressedKeyNum][0];
this.lastKeyStrokeIndex = 1;
copyStr();
}
 
if(this.lastKeyStrokeIndex >= KEY_MAP[pressedKeyNum].length)
{
this.lastKeyStrokeIndex = 0;
}
else
{
if( pressedKeyNum == 10 ) {
this.remove();
}
}
this.lastKeyStroke = keyCode;
this.lastKeyStrokeTime = System.currentTimeMillis();
}
 
}
