Determines the relative offset into the given text that best represents the given span in the view coordinate system.

Usage

From source file:FormattedTextFieldExample.java

public int viewToModel(float fx, float fy, Shape a, Position.Bias[] bias) {
    a = adjustAllocation(a);/*from  w ww . j  ava  2s.  c  om*/
    bias[0] = Position.Bias.Forward;

    int x = (int) fx;
    int y = (int) fy;
    Rectangle r = a.getBounds();
    int startOffset = element.getStartOffset();
    int endOffset = element.getEndOffset();

    if (y < r.y || x < r.x) {
        return startOffset;
    } else if (y > r.y + r.height || x > r.x + r.width) {
        return endOffset - 1;
    }

    // The given position is within the bounds of the view.
    int offset = Utilities.getTabbedTextOffset(contentBuff, getFontMetrics(), r.x, x, this, startOffset);
    // The offset includes characters not in the model,
    // so get rid of them to return a true model offset.
    for (int i = 0; i < offsets.length; i++) {
        if (offset <= offsets[i]) {
            offset = i;
            break;
        }
    }

    // Don't return an offset beyond the data
    // actually in the model.
    if (offset > endOffset - 1) {
        offset = endOffset - 1;
    }
    return offset;
}
