ALIGNABLE | Helper class to write alignable variant. See for example LABEL_ALIGNABLE
Alignment is useful only if x_expand_allowed or y_expand_allowed
is `True' and the space given to the object is bigger than it's
standard size.
|
ALIGNMENT_CONSTANTS |
|
ALIGNMENT | This class is used to describe widget position inside area
choosen by the container's layout.
x is in range 0.0 to 1.0 from left to right (0.5 is the middle)
y is in range 0.0 to 1.0 from top to bottom (0.5 is the middle)
Alignment is useful only if x_expand_allowed or y_expand_allowed
is `True' and the space given to the object is bigger than it's
standard size.
|
BASIC_FONT | BASIC_FONT describe basic font properties (like size, font family...)
and allow to draw characters (see class `FONT' for options like
underline).
Use `FONT_MANAGER' for `BASIC_FONT' creation.
|
COMBO | Allow to select one element from a list.
|
COMBO_HANDLE |
|
CONTAINER | A CONTAINER is designed to contain many widgets (called children).
Children are arranged in the container using some LAYOUT, and painted.
The CONTAINER may be seen as a shell: if the container is not
shrinkable, it will not shrink any of it's children. If the
container is shrinkable, it may shrink children that are shrinkable
but never shrink not shrinkable children (it's like a shell again).
The LAYOUT is an algorithm attached to the container. It has to
decide size and position for children.
|
CURSOR_SPACE | This class is only for inserting one pixel wide space to draw text cursor.
|
DRAWABLE | DRAWABLE is common classe for surfaces with painting
capabilities (like WINDOWs and PIXMAPs).
|
DRAWABLE_HANDLER | DRAWABLE_HANDLER is common class for objects who need low-level
access to DRAWABLE objects for basic drawing services.

|
DRAW_KIT | DRAW_KIT is a tool to make some free drawing, you may consider
it as a pen. You can draw points, lines, rectangles, arcs, words...
Difference with DRAW_STYLE is that you pre-select the drawable
to draw into and drawing functions automatically use this drawable.
|
DRAW_STYLE | DRAW_STYLE is low-level service who describe drawing attributes
(color, line width, font...)
|
EVENT_CATCHER | EVENT_CATCHER is the `JOB' that handle graphic interface
relative events. The event_catcher wait for such events and
emit signal relative to this event. Previously registred
procedure (via vision.*_connect) are executed.
For more information about `JOB', see lib/sequencer and
tutorial/sequencer directories.
|
FILL_RECTANGLE |
|
FONT | Class `FONT' allow to draw characters in style defined by some
`BASIC_FONT' and add some decoration like underline.
|
FONT_MANAGER | The font manager is singleton accessible via `font_manager'
from `GRAPHIC'. This class help to find the font on the system best
matching given whishes.
All created fonts are accessible in `fonts' attribute, the
default font on the system is the first one.
|
GRAPHIC_CONNECTION | This internal class allow to see the graphic connection as a
file who the sequencer has to wait data from.
Some graphic program may wait data from multiple source (files)
and wait for user requests (from the user interface) at the same time.
See lib/sequencer for more details.
|
GRAPHIC |
|
HORIZONTAL_LINE | `HORIZONTAL_LINE' is a widget you can use as separator. As it's
a widget, position and size are managed by the layout
associated with the container the line is put into.
|
IMAGE | This class allow to draw an image in memory (process memory)
and send it to the display. Each draw require lots of network
if the display is remote. A draw require hard work to convert
the image into display format (be the display local or remote).
See `PIXMAP' for image stored in the "display" memory.
|
LABEL_ALIGNABLE | Like `LABEL' with alignment capabilities. See `ALIGNABLE'
|
LABEL | `LABEL' is a widget to draw (unicode) string.
See class `TEXT_FIELD' if you want to allow the user to edit
the string.
|
LINE | Use line as widget (insert in container then position, draw and size
are automatic). Common ancestor for `HORIZONTAL_LINE' and `VERTICAL_LINE'
|
MENU_BAR |
|
MENU |
|
PIXMAP | `PIXMAP' is `DRAWABLE' area like `WINDOW' but allow you to draw "off
the screen" and the put it on the screen at any time.
The pixmap is in display memory, not in the process' memory
(see also `IMAGE').
|
RECTANGLE | Use rectangle as widget (insert in container then position, draw
and size are automatic).
|
RECT | Describe rectangular area.
|
SENSITIVE | SENSITIVE is common class for objects who the system may send events.
|
STATE_CONSTANTS | Constants state values.
|
STATE | This class describe the state of widgets.
|
TEXT_CURSOR_JOB | Draw blinking cursor in text area.
|
TEXT_FIELD | Class creates a text field which allows the user to grab a single line
of text.
|
VERTICAL_LINE | `VERTICAL_LINE' is a widget you can use as separator. As it's
a widget, position and size are managed by the layout
associated with the container the line is put into.
|
VISION | `VISION' object is singleton, accessible via `vision' from `GRAPHIC'
This object is responsible of "graphic mode" initialisation and
graphic events management.
This class give access to the events' loop (see also `start')
and to the display size.
|
VISION_LOOP_STACK | It's some loop_stack (see lib/sequencer) `EVENT_CATCHER' as
"special job". Use it like `LOOP_STACK'.
|
WIDGET | WIDGET is the most abstract class for all graphics objects.
width and height are current object size
min_width and min_height are the absolute minimal size
std_width and std_height are the needed dimensions to see the
entire object
If the object may not be shrink, size >= std
If the object may be shrink, size >= min
If the object may not be expanded, size <= std
If the object may be expanded, size may increase
