You need to add the following
import
statements to the
SketcherFrame
class:
import javax.swing.border.*;
import static javax.swing.Action.*;
Directory "Sketcher 7 with File toolbar buttons"
The first makes the border class names available without qualifiers and the second imports member
names in the
Action
class that define keys.
If you recompile Sketcher and run it, the window should look like that shown in
Figure 18-9
.
How It Works
Calling
putValue()
for an
Action
object stores the value you specify by the second argument with the
key you supply as the first argument. The new statements in the
createFileMenuActions()
method add
an
Icon
object from the
SketcherConstants
class as the value corresponding to the
LARGE_ICON_KEY
