FLtabs

FLtabs — Creates a tabbed FLTK interface.

Description

FLtabs is a file card tabs interface that is useful to display several areas containing widgets in the same windows, alternatively. It must be used together with FLgroup, another container that groups child widgets.

Syntax

FLtabs iwidth, iheight, ix, iy

Initialization

iwidth -- width of widget.

iheight -- height of widget.

ix -- horizontal position of upper left corner of the valuator, relative to the upper left corner of corresponding window. Expressed in pixels.

iy -- vertical position of upper left corner of the valuator, relative to the upper left corner of corresponding window. Expressed in pixels.

Performance

Containers are useful to format the graphic appearance of the widgets. The most important container is FLpanel, that actually creates a window. It can be filled with other containers and/or valuators or other kinds of widgets.

There are no k-rate arguments in containers.
