Abstractions:
|
|
|
|
Abstractions in this module encapsulate and contain state information for
|
|
certain entities that are necessary for the proper operation of this module.
|
|
The structures or classes that coorespond to these abstractions are defined
|
|
locally in this module. Code outside of this module only sees an opaque
|
|
data type, and *must* use functions in this module to manipulate the
|
|
abstractions. The developer of this module is free to put data members into
|
|
the locally defined structure or class, so that this module has the correct
|
|
state information to function properly.
|
|
|
|
XinWindow
|
|
|
|
this abstraction encapsulates the state and information for a created
|
|
window. also, we use an XinWindow to encapsulate the state and information
|
|
for horizontal and vertical scroll bars. scroll bars are the only controls
|
|
that Xin implements. XinWindow is also used for print windows.
|
|
|
|
examples are:
|
|
- the handle to the native window
|
|
- a pointer to the XinWindowEventHandler
|
|
- a pointer to the previous modal window, for proper implementation of modals
|
|
- a long integer for storing application data upon request of the module that
|
|
uses Xin
|
|
|
|
when creating an XinWindow, we pass in an XinWindowDef as an argument to
|
|
XinWindowCreate. an XinWindowDef contains all of the information necessary
|
|
to properly create either the scroll bar or the window. XinWindowType is an
|
|
enum that specifies whether to create a window or a scroll bar, and what kind
|
|
of window or scroll bar to create. The XinWindowMode determines "modality" of
|
|
the window. XinModeless is a normal window. XinModalReturn will create a window
|
|
that is the only window that can get focus and the XinWindowCreate function
|
|
will return as soon as the window is created. XinModalWait will create a window
|
|
that is the only window that can get focus and the XinWindowCreate function
|
|
will return when that window is destroyed. XinModalAutoclose will create a window
|
|
that will close automatically as soon as it loses focus. Note that XinModalReturn
|
|
and XinModalWait windows can be nested to open new modals windows. Creating
|
|
a modeless window while a modal window is open should create it without focus.
|
|
Autoclose windows can also be created "on top" of modal windows.
|
|
|
|
one of the more difficult things to handle is our concept of a modal window.
|
|
if MFC has a modal window, we should use it. however, if we need to implement
|
|
modal windows by disabling and re-enabling windows, we will wait until later
|
|
on in this project to implement them.
|
|
|
|
for historical reasons, in the XVT implementation, an XinWindow is, in fact,
|
|
the XVT window. this complicates the implementation because we then need to
|
|
keep state information on the window in a separate structure, and look up the
|
|
window information in a list whenever we need to access it. in the MFC
|
|
implementation, we will define a class that holds the state information on the
|
|
window, and the XinWindow should be a pointer to that class.
|
|
|
|
windows can be enabled or disabled. a disabled window still responds to
|
|
paint events, but can't be raised, and doesn't receive character or mouse
|
|
events.
|
|
|
|
windows can be visible or invisible. an invisible window does not generate
|
|
any paint events, nor receive character or mouse events.
|
|
|
|
Xin does not implement child windows.
|
|
|
|
the client area of a window is the area in which the module using Xin can draw.
|
|
the actual visible size of the window includes the border, title and menu which
|
|
are not part of the client area of the window. sometimes the
|
|
associated controls on the border are called the window decorations.
|
|
|
|
there are two XinWindows that are automatically created before
|
|
XinAppSystemSetupInit is called. the first is the task window. this allows
|
|
the module using Xin to manipulate the task window. the second is the screen
|
|
window. This allows Xin to draw directly onto the screen.
|
|
|
|
XinFont
|
|
|
|
this abstraction encapsulates the data necessary to specify a font. the
|
|
font can then be passed as an argument to XinWindowTextDraw, specifying
|
|
the font that the text is drawn in.
|
|
|
|
The XinFont can be created and set using a basic set of 'family' values, or
|
|
it can be the result of a font selection dialog. In either case, the
|
|
properties of 'bold', 'italic' and 'family' must be retrievable from the
|
|
XinFont. If the family does not match the basic set, then XinFontFamilyOther
|
|
will be used.
|
|
|
|
fonts can be mapped or unmapped.
|
|
after a font is mapped to a window, then the module using Xin can call
|
|
functions that use the font for drawing, or to get pixel metrics of the font.
|
|
if a font is mapped to a screen window, then the pixel metrics will be very
|
|
different than if the font is mapped to a printer window.
|
|
|
|
XinPrinterRec
|
|
|
|
This abstraction encapsulates the data for a selected printer.
|
|
It is used for printing operations and it should be possible to
|
|
save this structure in a file and load it later. (The size of
|
|
the structure is returned by XinPrintRecordCreate.)
|
|
|
|
XinBitmap
|
|
|
|
this abstraction encapsulates a bitmap that can be drawn into an XinWindow.
|
|
the internal format of an XinBitmap is the BMP format. this simplifies the
|
|
process of reading bitmaps from files or dlls, then subsequently drawing the
|
|
bitmap in a window.
|
|
|
|
XinRect
|
|
|
|
this structure contains the four points of a rectangle (top, left, bottom, right).
|
|
it is used in calls to many Xin functions.
|
|
|
|
XinPoint
|
|
|
|
this structure contains the horizontal and vertical components of a point (h, v)
|
|
|
|
Application
|
|
|
|
the Xin module contains the main (or win_main) or whatever function is
|
|
automatically executed when an MFC application starts. the module using Xin
|
|
needs to write two things for the minimal application. a function called
|
|
XinAppSystemSetupInit is written. this function initializes a data structure that
|
|
is passed in as an argument. this data structure defines certain application
|
|
wide characteristics such as the task window title, the task window event handler,
|
|
etc. in addition, the argc and argv variables are passed to this function for
|
|
processing if the user of Xin desires.
|
|
|
|
the sequence of actions when an application written using Xin starts is as follows:
|
|
1) win_main (or whatever in MFC) is called by the system.
|
|
2) win_main does any initial setup, puts argc and argv into the SystemSetup structure
|
|
3) win_main calls XinAppSystemSetupInit
|
|
4) data structures are set up so that when the system sends events to the MFC task
|
|
window handler, the events can be translated and sent to the Xin task window
|
|
event handler.
|
|
5) win_main returns.
|
|
6) windows starts sending event through to the task window event handler.
|
|
|
|
The "use_mdi" member of XinSystemSetup indicates if MDI should be enabled. The
|
|
Window menu will be specified with the tag XI_MENU_WIN. If that tag does not
|
|
exist, the Window menu will be created at the end of the existing menu.
|
|
The Window menu should contain Cascade, Tile Horizontally, Tile Vertically,
|
|
Close All, a separator(if any windows are open), and then the list of open windows,
|
|
including a "Windows..." item to open a separate dialog if there are too many
|
|
windows for the menu. Even if the XI_MENU_WIN tag exists, the window list will need
|
|
to be added to that existing menu. Of course, MDI will also handle iconizing of
|
|
top-level windows, etc.
|
|
|
|
Menus
|
|
|
|
Xin implements functions to manipulate menus. the functionality includes the
|
|
ability to set up an entire menu hierarchy with one call, replace a branch of
|
|
the menu hierarchy, replace a single item, change the enabled/disabled state of
|
|
any menu item, and change the checked state af a menu item.
|
|
|
|
there are no facilities to load menus from resources. the entire functionality
|
|
of the menu is available only through the api.
|
|
|
|
immediately after the application starts, the user of the Xin module will
|
|
call the function that sets up the entire menu. in the MFC implementation, we
|
|
may need to define a small "stub" menu in the windows resources. this stub
|
|
menu will not have anything in it other than a file menu with an exit item.
|
|
this stub menu will be replaced before the user has any oportunity to do any
|
|
menu selections.
|
|
|
|
there are two data structures associated with menus. an XinMenu is an array and
|
|
a count of child XinMenuItems an XinMenuItem is a branch on an XinMenu tree. it
|
|
may be the tip of a branch (a menu item that a user can select) or it may be the
|
|
parent of multiple child XinMenuItems, in which case, there is a submenu.
|
|
|
|
The text of menus can contain a '~' to indicate the shortcut key. For example,
|
|
"~File", "~Edit", and "E~xit".
|
|
|
|
Timers
|
|
|
|
this allows a module using Xin to set a timer
|
|
and get an event a specified number of miliseconds in the future. upon creation
|
|
of a timer, Xin returns a timer identifier (a long
|
|
integer) that identifies the timer. the timer id is part of the data for a timer
|
|
event, so that the module using Xin can set up multiple timers, and know which
|
|
timer an event is for. the timer identifier is also used when killing the timer.
|
|
|
|
Clipboard
|
|
|
|
Xin abstracts operations on the clipboard. the clipboard as implemented by Xin
|
|
can have two kinds of formats on it (text, and bitmap). any module using Xin can
|
|
query the clipboard, finding whether the desired format of data is on the clipboard,
|
|
then the module can get the contents of the clipboard.
|
|
|
|
Printing
|
|
|
|
printing has much in common with displayed windows. before printing, a print window
|
|
needs to be created. after the print window is created, fonts can be mapped to
|
|
the print window, rectangles, lines, and text can be drawn in the window, etc.
|
|
there is one fundimental difference. after the print window is created, the module
|
|
using Xin must call XinPrintPageStart. then, the module using Xin calls
|
|
XinPrintBandNext until it returns NULL. if it is necessary to paint a band at a
|
|
time, then XinPrintBandNext will return a rectangle several times. After each return,
|
|
the area within the returned rectangle should be drawn by the module using Xin. After
|
|
XinPrintBandNext returns NULL, then the module using Xin should call XinPrintPageEnd.
|
|
This will cause the page to be printed. If the printer and the printer driver are
|
|
capable of printing the entire page at once, then XinPrintBandNext will only return
|
|
a rectangle once.
|
|
|
|
Bob, according to a comment written by John Lilley in the report writer, banding is
|
|
no longer used for any XVT implementation. Do we really need to continue to support
|
|
banding?
|
|
|
|
If that's true, then no. But is it true? - Bob

|
Events
|
|
|
|
Xin is an event based system. When Xin is informed of certain events in the
|
|
underlying system, then Xin should send an event to the module using Xin. the
|
|
method of sending an event to the module using Xin is as follows:
|
|
|
|
1) declare an automatic variable of type XinEvent
|
|
2) set every byte in the XinEvent structure to '\0'
|
|
3) fill in the XinEvent structure. information that needs to be specified is
|
|
the event type, and information specific to that type of event.
|
|
4) call the event handler that the module using Xin specified when the application
|
|
was created, or when the window was created.
|
|
|
|
Below is the set of events that Xin needs to generate:
|
|
|
|
XinEventCreate
|
|
|
|
This event is sent when a window is created. When the application is starting,
|
|
then this event is sent to the task window event handler, which was specified
|
|
in the function XinAppSystemSetupInit. This will be the first event for any
|
|
window.
|
|
|
|
XinEventDestroy
|
|
|
|
This event is sent when a window is destroyed. When the application is
|
|
terminating, then this event is sent to the task window event handler. The
|
|
window will still be valid during this event, but no other event will occur
|
|
for the window after this event.
|
|
|
|
XinEventFocus
|
|
|
|
This event is sent when a window is gaining or loosing keyboard focus. A
|
|
boolean variable
|
|
in the XinEvent structure indicates whether the window is gaining or losing
|
|
focus.
|
|
|
|
XinEventResize
|
|
|
|
This event is sent when a window is re-sized or minimized.
|
|
|
|
XinEventPaint
|
|
|
|
This event is sent when the windowing system needs to have the module using
|
|
Xin paint a certain region of a window.
|
|
|
|
XinEventCloseButton
|
|
|
|
This event is sent when the user either clicks on the close button in the
|
|
upper right corner of the window, double clicks on the window menu at the
|
|
upper left corner of the window, or selects close on the window menu. the
|
|
window should not be closed when the above actions happen. rather, Xin
|
|
lets the module using Xin close the window if it desires.
|
|
|
|
XinEventMouseDown
|
|
|
|
This event is sent when the user presses the mouse button within the
|
|
bounderies of a window.
|
|
|
|
Xin reports the pressed state of the shift, control, and alt keys when
|
|
generating this event.
|
|
|
|
XinEventMouseUp
|
|
|
|
This event is sent when the user releases the mouse button within the
|
|
bounderies of a window. If the mouse is trapped to a window, then this
|
|
event is sent to the window in which the mouse is trapped, regardless of
|
|
whether the mouse is over that window or not.
|
|
|
|
Xin reports the pressed state of the shift, control, and alt keys when
|
|
generating this event.
|
|
|
|
XinEventMouseMove
|
|
|
|
This event is sent when the user moves the mouse within the bounderies
|
|
of a window. If the mouse is trapped to a window, then this
|
|
event is sent to the window in which the mouse is trapped, regardless of
|
|
whether the mouse is over that window or not. If the mouse is trapped to
|
|
a window, and the mouse is held down, then mouse move events are continually
|
|
generated, whether the mouse is moving or not.
|
|
|
|
Xin reports the pressed state of the shift, control, and alt keys when
|
|
generating this event.
|
|
|
|
XinEventMouseDouble
|
|
|
|
This event is sent when the user double clicks the mouse within the
|
|
bounderies of a window. The sequence of events when the user double clicks
|
|
and releases the mouse is:
|
|
XinEventMouseDown
|
|
XinEventMouseUp
|
|
XinEventMouseDouble
|
|
XinEventMouseUp
|
|
|
|
Xin reports the pressed state of the shift, control, and alt keys when
|
|
generating this event.
|
|
|
|
XinEventCharacter
|
|
|
|
This event is sent to a window when the window has keyboard focus, and the
|
|
user presses a key in the window. Character events are translated to
|
|
Xin virtual characters. The list of virtual characters is:
|
|
|
|
XI_KEY_DEL delete key
|
|
XI_KEY_UP up arrow key
|
|
XI_KEY_DOWN down arrow key
|
|
XI_KEY_RIGHT right arrow key
|
|
XI_KEY_LEFT left arrow key
|
|
XI_KEY_PREV page up key
|
|
XI_KEY_NEXT page down key
|
|
XI_KEY_LHOME home key
|
|
XI_KEY_LEND end key
|
|
XI_KEY_WLEFT control left arrow key
|
|
XI_KEY_WRIGHT control right arrow key
|
|
XI_KEY_BTAB shift tab key
|
|
XI_KEY_F1 function keys
|
|
XI_KEY_F2
|
|
XI_KEY_F3
|
|
XI_KEY_F4
|
|
XI_KEY_F5
|
|
XI_KEY_F6
|
|
XI_KEY_F7
|
|
XI_KEY_F8
|
|
XI_KEY_F9
|
|
XI_KEY_F10
|
|
XI_KEY_F11
|
|
XI_KEY_F12
|
|
|
|
Xin reports the pressed state of the shift, control, and alt keys when
|
|
generating this event.
|
|
|
|
XinEventMenuCommand
|
|
|
|
This event is sent when the user selects a menu item. The event reports the
|
|
menu tag of the selected menu item. There are no events for navigating menus.
|
|
|
|
Xin reports the pressed state of the shift and control keys when generating
|
|
this event.
|
|
|
|
XinEventControl
|
|
|
|
This event is sent when the user operates a scroll bar that was set up by
|
|
Xin. The control_id in the XinEvent structure is the control id specified
|
|
when the scroll bar was created.
|
|
|
|
In XinControlInformation, the following fields are set:
|
|
type is set to either XinWindowTypeHorizontalScrollBar or
|
|
XinWindowTypeVerticalScrollBar
|
|
win is set to the scroll bar window
|
|
v.scroll.action is set to one of XinScrollBarActionLineUp
|
|
XinScrollBarActionLineDown
|
|
XinScrollBarActionPageUp
|
|
XinScrollBarActionPageDown
|
|
XinScrollBarActionThumb
|
|
XinScrollBarActionThumbTrack
|
|
v.scroll.position is set to the current position of the thumb of the
|
|
scroll bar.
|
|
|
|
XinEventTimer
|
|
|
|
This event is sent when a timer expires. The module using Xin can set or
|
|
kill timers. See the discussion on timers for more details.
|
|
|
|
XinEventQuit
|
|
|
|
This event is sent when something or someone requests that Xin terminate.
|
|
For instance, when someone shuts down Windows95, then this event is sent.
|
|
The application, based on its state, can query the user to see if the user
|
|
wants to save changed data, discard changed data, or cancel the shutdown
|
|
operation. If, after processing input from the user, and it is still OK
|
|
to shut down, then the module using Xin should call XinAppQuitOk. If
|
|
XinAppQuitOk is not called, then the shutdown operation is aborted.
|
|
|
|
XinEventFont
|
|
|
|
This event does not need to be implemented in MFC.

Drawing
|
|
|
|
this section details the semantics and behaviors of drawing in windows.
|
|
|
|
Mathmatical Rectangles
|
|
|
|
Many of the Xin functions work using 'Mathmatical Rectangles'. By this, we
|
|
mean that a rectangle refers to the lines between the pixels, not the pixels
|
|
themselves. For instance, when we draw a rectangle, we specify a mathmatical
|
|
rectangle, and the pixels that get drawn are those just inside the mathmatical
|
|
rectangle.
|
|
|
|
the following diagram needs to be viewed in a fixed font to appear correctly.
|
|
it represents a grid of pixels where the mathmatical lines between the pixels
|
|
are numbered, and the spaces represent pixels.
|
|
|
|

| | | | | | | | |
|
|
7 -----------------
|
|
| | | | | | | | |
|
|
-----------------
|
|
|
|
for instance, if we were to draw a hollow rectangle where:
|
|
top = 1
|
|
left = 1
|
|
right = 4
|
|
bottom = 4
|
|
then the following pixels would get drawn:
|
|
|
|
0 1 2 3 4 5 6 7 8
|

-----------------
|
|
|
|
at various points in this module, we will refer to mathmatical rectangles,
|
|
and to properly identify the semantics of drawing functions, we will
|
|
use diagrams like the ones above.
|
|
|
|
Clipping
|
|
|
|
when clipping is set for a window, the drawing functions only draw within
|
|
the clipping rectangle. the rectangle for clipping is a mathmatical
|
|
rectangle.
|
|
|
|
the functions that clip to the clipping rectangle are:
|
|
- XinWindowRectDraw
|
|
- XinWindowLineDraw
|
|
- XinWindowTextDraw
|
|
- XinWindowBitmapDraw
|
|
- XinWindowIconDraw
|
|
|
|
note that carets do not clip to the clipping rectangle. there is a
|
|
rectangle passed in to the XinWindowCaretOn for clipping of the caret.
|
|
|
|
Text Drawing
|
|
|
|
The vertical metrics of a font have three components: ascent, descent,
|
|
and leading. these are pixel counts of the components of a font.
|
|
|
|
____
|
|
leading ____
|
|
|
|
|
|
|
|
xxxxxx
|
|
x x
|
|
ascent x x
|
|
x x
|
|
baseline ____ xxxxx
|
|
x
|
|
descent x
|
|
____ xxxx
|
|
|
|
the baseline is the mathmatical line upon which most text (without
|
|
descenders) is drawn. ascent is the number of pixels above the
|
|
baseline to the top of the font. descent is the number of pixels
|
|
available for the descenders. leading is the space between the lines
|
|
of drawn text.
|
|
|
|
There are two modes of text drawing, opaque, and not opaque. If opaque,
|
|
the background color is drawn in the entire leading/ascent/descent area.
|
|
The background color is specified by XinWindowColorTextBackSet or by
|
|
the drawing tools.
|
|
|
|
If opaque is set to false, then only the text itself is drawn, using the
|
|
foreground color.
|
|
|
|
XinDrawMode
|
|
|
|
when drawing, there are two modes of drawing: copy and xor. if the draw
|
|
mode is copy, then the pixels are simply copied to the window. if the draw
|
|
mode is xor, then, if drawn on pixels equalling the back_color of the window,
|
|
drawing will attempt to produce the fore_color of the tool (pen/brush/text).
|
|
Drawing on pixels of fore_color will attempt to produce back_color. The
|
|
operation is self-reversing. the only thing that xor mode is used for is
|
|
drawing rubber band rectangles when moving columns, moving rows, resizing
|
|
columns and resizing rows. drawing in xor mode assumes that the window is
|
|
on top, and will remain on top until the rubber banding operation is complete.
|
|
|
|
XinPen
|
|
|
|
A pen specifies what is drawn for lines or rectangle borders. The 'width'
|
|
determines the number of pixels for the line or border. The 'pattern' may
|
|
be hollow, solid or dashed. If hollow, then no border will be drawn for a
|
|
rectangle. Solid and dashed lines are drawn using the 'fore_color'. Dashed
|
|
lines will not draw in the space between the dashes.
|
|
|
|
XinBrush
|
|
|
|
a brush specifies what is drawn in the interior of a rectangle. there are
|
|
two fields in an XinBrush data structure: 'pattern', and 'color'. if
|
|
'pattern' is XinBrushHollow, then 'color' is ignored, and the interior of
|
|
the rectangle (the pixels other than those just inside the mathmatical
|
|
rectangle) are left alone.
|
|
|
|
if 'pattern' is XinBrushSolid, then the pixels in the interior of the
|
|
rectangle are drawn in the specified color.
|
|
|
|
XinDrawTools
|
|
|
|
drawing tools is a convenience feature of Xin. it allows the user of Xin
|
|
to set or get the state of drawing (draw mode, brush, pen, fore color,
|
|
back color, and text opaqueness) with one function call.
|
|
|
|
Drawing Rectangles
|
|
|
|
There are three cases to consider when drawing rectangles:
|
|
|
|
1) solid pen and solid brush
|
|
2) hollow pen and solid brush
|
|
3) solid pen and hollow brush
|
|
|
|
note that it does not make any sense to draw with a hollow pen and a hollow
|
|
brush. this would draw nothing.
|
|
|
|
Example 1: solid red pen and solid blue brush
|
|
top = 1
|
|
left = 1
|
|
bottom = 5
|
|
right = 5
|
|
|
|
this will draw a red one pixel wide rectangle just inside the
|
|
specified mathmatical rectangle. it will fill the area inside
|
|
the red rectangle of pixels with blue pixels.
|
|
|
|
the following would be the result, r is a red pixel, b is a blue pixel
|
|
|
|
0 1 2 3 4 5 6 7 8

|
|
top = 1
|
|
left = 1
|
|
bottom = 5
|
|
right = 5
|
|
|
|
this will fill the mathmatical rectangle with blue pixels.
|

|
|
top = 1
|
|
left = 1
|
|
bottom = 5
|
|
right = 5
|
|
|
|
this will draw a blue rectangle, one pixel wide, just inside
|
|
the mathmatical rectangle.
|

the following would be the result, b is a blue pixel
|
|

Drawing Lines
|
|
|
|
There are three cases to consider when drawing lines:
|
|
|
|
1) horizontal lines
|
|
2) vertical lines
|
|
3) diagonal lines
|
|
|
|
Example 1: a horizontal line
|
|
from
|
|
horizontal = 1
|
|
vertical = 1
|
|
to
|
|
horizontal = 6
|
|
vertical = 1
|
|
|
|
this will draw the row of pixels just below the mathmatical line.
|
|
|

|
Example 2: a vertical line
|
|
from
|
|
horizontal = 1
|
|
vertical = 1
|
|
to
|
|
horizontal = 1
|
|
vertical = 7
|
|
|
|
this will draw the row of pixels just to the right of
|
|
the mathmatical line.

horizontal = 1
|

to
|
|
horizontal = 4
|
|
vertical = 4
|
|
|
|
taking the mathmatical rectangle formed by placing the two points
|
|
at oposite corners, the two pixels just inside the corners of the
|
|
mathmatical rectangle are drawn, with some pixels in between. if
|
|
the absolute value of the rise and the run are equal, i.e. the line
|
|
is a diagonal line 45 degrees off of horizontal and vertical, then
|
|
a straight diagonal line is drawn.

Other Notes
|
|
|
|
Mouse Trapping
|
|
|
|
the mouse can be trapped to a window. when the mouse is trapped, all mouse
|
|
events until the mouse is released go to the window in which the mouse is
|
|
trapped. this ensures that if a window receives a mouse down event, it will
|
|
be guarenteed to receive the mouse up event.
|
|
|
|
while the mouse is trapped, if the mouse button is down, the window is
|
|
guarenteed to receive mouse move events even if the mouse is not moving. this
|
|
facilitates the behavior where the user is selecting text, drags the mouse
|
|
outside of the region where they are selecting text, and the text continually
|
|
scrolls until the user drags the mouse back into the region, or the user
|
|
releases the mouse button.
