30 * Overall layout of this widget is as follows:
|
|
|
31 *
|
|
|
32 * ________ ,---------. _________
|
|
|
33 * | label || Label || Label | \ tabs
|
|

34 * |________|| ||_________| /
|
|
|
35 * |+----------------------------+| \
|
|
|
36 * || || |
|
|
|
37 * || child widget window || > frame
|
|
|
38 * |+----------------------------+| |
|
|
|
39 * +------------------------------+ /
|
|
|
40 *
|
|
|
41 * The height of the tabs includes the shadow width, top and bottom
|
|
|
42 * margins, and the height of the text.
|
|
|
43 *
|
|
|
44 * The height of the frame includes the top and bottom shadow width and the
|
|
|
45 * size of the child widget window.
|
|
|
46 *
|
|
|
47 * The tabs overlap the frame and each other vertically by the shadow
|
|
|
48 * width, so that when the topmost tab is drawn, it obliterates part of
|
|
|
49 * the frame.

57 bad idea.
