Examples of TextLayout

ae.java.awt.font.TextLayout
slate graphics to origin of layout on screen g.translate(loc.getX(), loc.getY()); Shape[] carets = layout.getCaretShapes(next.getInsertionIndex()); g.draw(carets[0]); if (carets[1] != null) { g.draw(carets[1]); } }
Drawing a selection range corresponding to a substring in the source text. The selected area may not be visually contiguous:
```
 // selStart, selLimit should be relative to the layout, // not to the source text int selStart = ..., selLimit = ...; Color selectionColor = ...; Shape selection = layout.getLogicalHighlightShape(selStart, selLimit); // selection may consist of disjoint areas // graphics is assumed to be tranlated to origin of layout g.setColor(selectionColor); g.fill(selection); 
```
Drawing a visually contiguous selection range. The selection range may correspond to more than one substring in the source text. The ranges of the corresponding source text substrings can be obtained with getLogicalRangesForVisualSelection():
```
 TextHitInfo selStart = ..., selLimit = ...; Shape selection = layout.getVisualHighlightShape(selStart, selLimit); g.setColor(selectionColor); g.fill(selection); int[] ranges = getLogicalRangesForVisualSelection(selStart, selLimit); // ranges[0], ranges[1] is the first selection range, // ranges[2], ranges[3] is the second selection range, etc. 
```
Note: Font rotations can cause text baselines to be rotated, and multiple runs with different rotations can cause the baseline to bend or zig-zag. In order to account for this (rare) possibility, some APIs are specified to return metrics and take parameters 'in baseline-relative coordinates' (e.g. ascent, advance), and others are in 'in standard coordinates' (e.g. getBounds). Values in baseline-relative coordinates map the 'x' coordinate to the distance along the baseline, (positive x is forward along the baseline), and the 'y' coordinate to a distance along the perpendicular to the baseline at 'x' (postitive y is 90 degrees clockwise from the baseline vector). Values in standard coordinates are measured along the x and y axes, with 0,0 at the origin of the TextLayout. Documentation for each relevant API indicates what values are in what coordinate system. In general, measurement-related APIs are in baseline-relative coordinates, while display-related APIs are in standard coordinates. @see LineBreakMeasurer @see TextAttribute @see TextHitInfo @see LayoutPath
