The Fl_Tabs widget is the "file card tabs" +interface that allows you to put lots and lots of buttons and +switches in a panel, as popularized by many toolkits. +
Clicking the tab makes a child visible() (by calling -show() on it) and all other children are invisible (by calling -hide() on them). Usually the children are -Fl_Group widgets containing several widgets -themselves.
-Each child makes a card, and it's label() is printed on the -card tab (including the label font and style). The color of that child -is used to color the card as well. Currently this only draws nicely if -you set box() to the -default FL_THIN_UP_BOX or to FL_FLAT_BOX, which gets -rid of the edges drawn on the sides and bottom.

The size of the tabs is controlled by the bounding box of the -children (there should be some space between the children and the edge -of the Fl_Tabs), and the tabs may be placed "inverted" on the -bottom, this is determined by which gap is larger. It is easiest to -lay this out in fluid, using the fluid browser to select each child -group and resize them until the tabs look the way you want them to.

The destructor also deletes all the children. This +allows a whole tree to be deleted at once, without having to +keep a pointer to all the children in the user code. A kludge +has been done so the Fl_Tabs and all of it's children +can be automatic (local) variables, but you must declare the +Fl_Tabs widget first so that it is destroyed +last. + +

+Fl_Color fl_average_color(Fl_Color c1, Fl_Color c2, float weight); ++ +
Returns the weighted average color between the two colors. +The red, green, and blue values are averaged using the following +formula: + +
+color = c1 * weight + c2 * (1 - weight) ++ +
Thus, a weight value of 1.0 will return the
+first color, while a value of 0.0 will return the second color.

+Fl_Color fl_contrast(Fl_Color fg, Fl_Color bg); ++ +
Returns the foreground color if it contrasts sufficiently
+with the background color. Otherwise, returns
+FL_WHITE or FL_BLACK depending on
+which color provides the best contrast.
