Lesson 2: Drawing Styled Text

Exercise 2: Drawing Styled Text

  1. How do your create a text string with an interesting fill pattern?
    A. Create a TextAttribute object with and call its fillPattern method.
    B. Create a Font object from an Image object.
    C. Create a Shape from the TextLayout's outline, set the graphics context clip area to that Shape, and draw the image.
    D. Set the graphics context's fill to an Image object.

  2. What does this code segment do? 

    Font f=new Font("Times", Font.BOLD, 24);
AttributedString ats=new AttributedString("Magic");
ats.addAttribute(TextAttribute.FONT, f);
ats.addAttribute(TextAttribute.UNDERLINE, 
		TextAttribute.UNDERLINE_ON);
AttributedCharacterIterator iter=ats.getIterator();

FontRenderContext frc=g2.getFontRenderContext();
tl=new TextLayout(iter, frc);
g2.setColor(Color.red);
tl.draw(g2, (float)30, (float)50);

Lesson 3: Interacting with Styled Text

Exercise 3: Interacting with Styled Text

  1. How do you calculate the current insertion point moving right?
    A. By starting with a TextHitInfo object that represents the current insertion point, and calling TextLayout.getCaretShapes when the right arrow key is pressed.

    B. By starting with a TextHitInfo object that represents the current insertion point, and calling TextLayout.getHitTestChar when the right arrow key is pressed.

    C. By starting with a TextHitInfo object that represents the current insertion point, and calling TextLayout.getNextLeftHit when the right arrow key is pressed.

    D. By starting with a TextHitInfo object that represents the current insertion point, and calling TextLayout.getNextRightHit when the right arrow key is pressed.

  2. What is the best way to draw the highlight region for selected text?


    A. Draw the highlight region first and draw the text over it.
    B. Draw the text first and draw the highlight region over it.
    C. It does not matter.

    B. French.
    C. Sanskrit.
