46 * +------------------------------+ /
|
|
|
47 *
|
|
|
48 * The height of the tabs includes the shadow width, top and bottom
|
|
|
49 * margins, and the height of the text.
|
|
|
50 *
|
|
|
51 * The height of the frame includes the top and bottom shadow width and the
|
|
|
52 * size of the child widget window.
|
|
|
53 *
|
|
|
54 * The tabs overlap the frame and each other vertically by the shadow
|
|
|
55 * width, so that when the topmost tab is drawn, it obliterates part of
|
|
|
56 * the frame.
