PyGadgets Launcher Bar

The PyGadgets script runs some of the same programs as PyDemos, but for real, prac-
tical use, not as demonstrations. Both scripts use launchmodes to spawn other programs,
and display bars of launcher buttons, but PyGadgets is a bit simpler because its task is
more focused. PyGadgets also supports two spawning modes—it can either start a
canned list of programs immediately and all at once, or display a GUI for running each
program on demand. Figure 10-19 shows the launch bar GUI made in on-demand mode
when it first starts; PyDemos and PyGadgets can be run at the same time, and both
grow with their window if resized (try it on your own to see how).
