Some practical graphical user interface methods

This function has been applied repeatedly to multiple mobile phone application software platforms

Usage: Parameter definition: str--string to split

font--fonts

rowmaxw--width per line after split

Support designator:

\ n Line Change

\ t Inserts a space of two Chinese characters length

public static final string[] Clipstring (String str,font font,int rowmaxw) {
if (str = null)
return null;　　 　 　
if (Rowmaxw < Font.charwidth (' ha '))
Rowmaxw = font.charwidth (' ha ');
int strid = 0;
int roww = 0;
Vector strmanager = new vector ();
Char ch = '; 　
while (Str.length () > Strid) {
ch = str.charat (Strid);
　　Switch (CH)
{
case ' \ n ':
Strmanager.addelement (str.substring (0,strid));
str = str.substring (strid+1);
Roww = 0;
Strid = 0;
break; 　　
case ' \ t ':
StringBuffer sb = new StringBuffer (str);
Sb.deletecharat (Strid);
Sb.insert (Strid, "");
str = sb.tostring ();
break; 　　
Default:
if (Roww + font.charwidth (ch) > Rowmaxw) {
Strmanager.addelement (str.substring (0,strid));
str = str.substring (Strid);
Roww = 0;
Strid = 0; 　　
}else{

}
}
}
Strmanager.addelement (str);
string[] O_str = new string[strmanager.size ()];
Strmanager.copyinto (O_STR);
return o_str;
