About cursor

[jackken123]

Hello,
Now I got some question about cursor
These are the code for cursor, am I right?

Window_Selectable.prototype.updateCursor = function() {
    if (this._cursorAll) {
        var allRowsHeight = this.maxRows() * this.itemHeight();
        this.setCursorRect(0, 0, this.contents.width, allRowsHeight);
        this.setTopRow(0);
    } else if (this.isCursorVisible()) {
        var rect = this.itemRect(this.index());
        this.setCursorRect(rect.x, rect.y, rect.width, rect.height);
    } else {
        this.setCursorRect(0, 0, 0, 0);
    }
};

Window.prototype.setCursorRect = function(x, y, width, height) {
    var cx = Math.floor(x || 0);
    var cy = Math.floor(y || 0);
    var cw = Math.floor(width || 0);
    var ch = Math.floor(height || 0);
    var rect = this._cursorRect;
    if (rect.x !== cx || rect.y !== cy || rect.width !== cw || rect.height !== ch) {
        this._cursorRect.x = cx;
        this._cursorRect.y = cy;
        this._cursorRect.width = cw;
        this._cursorRect.height = ch;
        this._refreshCursor();
    }
};

Window.prototype._refreshCursor = function() {
    var pad = this._padding;
    var x = this._cursorRect.x + pad - this.origin.x;
    var y = this._cursorRect.y + pad - this.origin.y;
    var w = this._cursorRect.width;
    var h = this._cursorRect.height;
    var m = 4;
    var x2 = Math.max(x, pad);
    var y2 = Math.max(y, pad);
    var ox = x - x2;
    var oy = y - y2;
    var w2 = Math.min(w, this._width - pad - x2);
    var h2 = Math.min(h, this._height - pad - y2);
    var bitmap = new Bitmap(w2, h2);

    this._windowCursorSprite.bitmap = bitmap;
    this._windowCursorSprite.setFrame(0, 0, w2, h2);
    this._windowCursorSprite.move(x2, y2);

    if (w > 0 && h > 0 && this._windowskin) {
        var skin = this._windowskin;
        var p = 96;
        var q = 48;
        bitmap.blt(skin, p+m, p+m, q-m*2, q-m*2, ox+m, oy+m, w-m*2, h-m*2);
        bitmap.blt(skin, p+m, p+0, q-m*2, m, ox+m, oy+0, w-m*2, m);
        bitmap.blt(skin, p+m, p+q-m, q-m*2, m, ox+m, oy+h-m, w-m*2, m);
        bitmap.blt(skin, p+0, p+m, m, q-m*2, ox+0, oy+m, m, h-m*2);
        bitmap.blt(skin, p+q-m, p+m, m, q-m*2, ox+w-m, oy+m, m, h-m*2);
        bitmap.blt(skin, p+0, p+0, m, m, ox+0, oy+0, m, m);
        bitmap.blt(skin, p+q-m, p+0, m, m, ox+w-m, oy+0, m, m);
        bitmap.blt(skin, p+0, p+q-m, m, m, ox+0, oy+h-m, m, m);
        bitmap.blt(skin, p+q-m, p+q-m, m, m, ox+w-m, oy+h-m, m, m);
    }
};

So when I use

this._windowCursorSprite.tint = '#FFFF00';

in Window_Selectable.prototype.updateCursor
I can change the color.
Then I was thinking, can I change CursorRect to a picture?(not just a box)
Can someone help me with this?
Change CursorRect to a picture, maybe in the img/pictures.

Thank you.
