Lively Kernel Tutorial: (7) Windows and Window Controls
The Lively Kernel supports windows that behave
much like windows in conventional desktop operating systems.
Windows are distinguished from other objects in the system
by the presence of a title bar. The title bar contains the
name of the window as well as some window control buttons
to close or collapse the window (red and yellow buttons, respectively),
as well as to open the popup menu of the window (blue button).
Window controls have balloon help to summarize the behavior
of each control.
Notes:
A window can be moved by grabbing it from the title bar.
A window can be resized or rotated using the handles in its corners.
Pressing the red Close button will close the window.
Pressing the yellow Collapse button once will collapse
the window. Pressing the collapse button another time will
restore/expand the window. Note that a collapsed window can be moved
independently of the normal location of the window on the screen.
The blue Menu button opens a menu that allows the contents
of the window to be manipulated.
Try it yourself! Move the window around by grabbing its title bar.
Try out the menus and the collapse/expand functionality. Furthermore,
try rotating and resizing the window. Finally,
close the window by pressing its Close button.
Note that all the objects inside the Sun 3D logo below are
full-fledged objects that you can manipulate directly.
