I've made sure that all code has syntax highlighting, I did it all at once(which took a long time) so it's easier to reverse if this wasn't desired.

<big><presyntaxhighlight lang="cpp">
void draw(int fn = FW_NO_REFRESH)const;
</presyntaxhighlight></big>
If '''fn''' is '''FW_REFRESH''' or '''FW_FULL_FRAME''', it will call its parent draw with '''fn''' as its argument. Then It will draw all the '''Fields''' in the '''Dialog'''. <br />
If '''fn''' is '''FW_NO_REFRESH''', then it will just draw all the '''Fields''' in the '''Dialog'''.<br />
If '''fn''' is a non-zero positive value, then it will only draw '''Field''' number '''fn''' in the dialog. (First added '''Field''' is field number one.)
<big><presyntaxhighlight lang="cpp">
int edit(int fn = FW_NO_REFRESH);
</presyntaxhighlight></big>
If '''FWDialog''' is not editable (all fields are non-editable), it will just display the Dialog and then waits for the user to enter a key and then terminates the function returning the key.<br />
# For any other key, terminate the edit function returning the character which caused the termination.
<big><presyntaxhighlight lang="cpp">
int add(FWField* field, bool dynamic = true);
</presyntaxhighlight></big>

<big><presyntaxhighlight lang="cpp">
FWLineEdit(char* Str, int Row, int Col, int Width,
int Maxdatalen, int* Insertmode,
bool Bordered = false,
const char* Border=FW_BORDER_CHARS);
</presyntaxhighlight></big>
LineEdit, sets the Field's _data to the value of str. If LineEdit is instantiated with this constructor then it will edit an external string provided by the caller function of LineEdit. LineEdit in this case is not creating any dynamic memory, therefore _dyn is set to false (therefore the destructor will not attempt to deallocate the memory pointed by _data).<br />
The location (row and col) and Bordered are directly passed to the parent (FWField) and str is passed as data to the parent constructor. Unlike Label, LineEdit could have border or not so depending on this (Bordered being true or false) the Height is set to 3 or 1 respectfully. <br />
(hint: use '''? :''' operator to pass the proper value to FWField's constructor)
<big><presyntaxhighlight lang="cpp">
FWLineEdit(int Row, int Col, int Width,
int Maxdatalen, int* Insertmode,
bool Bordered = false,
const char* Border=FW_BORDER_CHARS);
</presyntaxhighlight></big>
Works exactly like the previous constructor with one difference; since no external data is passed to be edited here, this constructor must allocate enough dynamic memory to accommodate editing of '''Maxdatalen''' characters. Then make it an empty string and set Fields's _data to point to it. Make sure _dyn is set to true in this case, so the destructor knows that it has to deallocate the memory at the end.
<big><presyntaxhighlight lang="cpp">
~FWLineEdit();
</presyntaxhighlight></big>
If '''_dyn''' is true, it will deallocate the character array pointed by Fields's '''_data'''
<big><presyntaxhighlight lang="cpp">
void draw(int Refresh = FW_NO_REFRESH)const;
</presyntaxhighlight></big>
If the Border is visible, it will first call Border's draw passing '''Refresh'''as an argument to it.<br />
Then it will make a direct call to iol_display to show the data kept in Field's '''_data'''.<br />
*len: width() (''reduce by two is border is visible''')
<big><presyntaxhighlight lang="cpp">
int edit();
</presyntaxhighlight></big>
Makes and direct call to, and returns '''iol_edit()'''.
For the coordinates and width arguments follow the same rules as the draw function.
For the rest of the arguments of iol_edit, use the attributes of '''FWLineEdit'''.
<big><presyntaxhighlight lang="cpp">
bool editable()const;
</presyntaxhighlight></big>
Always return true;
<big><presyntaxhighlight lang="cpp">
void set(const void* Str);

===Methods===
<big><presyntaxhighlight lang="cpp">FWButton(const char *Str, int Row, int Col,
bool Bordered = true,
const char* Border=FW_BORDER_CHARS);
</presyntaxhighlight></big>
When creating a Button, allocate enough memory to hold the contents of the '''Str''' and set Field's _data to point to it. Then copy the content of '''Str''' into the newly allocated memory.<br />
Pass all the arguments directly to Field's constructor.<br />
For width: Set width to the length of '''Str''' + 2 (adding 2 for surrounding brackets) or if the Button is bordered set width to the length of '''Str''' + 4 (adding 2 for surrounding brackets and 2 for the borders).
For height: Set the height to 1 or if the Button is bordered, set the height to 3.
<big><presyntaxhighlight lang="cpp">
~FWButton();
</presyntaxhighlight></big>
Deallocates the allocated memory pointed by Field's '''_data'''.
<big><presyntaxhighlight lang="cpp">

*:display the text at absRow()+1 and absCol()+2
<big><presyntaxhighlight lang="cpp">
int edit();
</presyntaxhighlight></big>
First draw() the Button, then surround it by squared brackets, place the cursor under the first character of Button's text and wait for user entry.<br />
When user hits a key, if the key is ENTER_KEY or SPACE, return FW_BUTTON_HIT (defined in confw.h) otherwise return the entered key.<br />
Make sure the surrounding characters are replaced with spaces before exiting the edit() method.

If the container() is NULL then this function works exactly like LineEdit::edit().<br />
If the container() is not NULL:
==FWText==
The FWText class splits a string of text into series if strings at newline characters, then starts editing them in a text area one string at a time.
Each string in this array of strings represents a line in text.
The lines can scroll left and right (already implemented in iol_edit) and up and down during the edit if needed.
at any time by calling the data() method the array of strings is converted back to a newline separated and null terminated array of characters (Converted back to text) and returned.

<big><presyntaxhighlight lang="cpp">
bool _readOnly;
</presyntaxhighlight></big>
Keeps the status of the text being read only, or editable. (note that when read only, you can still scroll the text to left and right or up and down, but you can't modify the text).<br />
This flag is passed to iol_edit for the same reason.
<big><presyntaxhighlight lang="cpp">
int _curpos;

Variables to be used with iol_edit to edit the lines of text.
<big><presyntaxhighlight lang="cpp">
int _lcurpos;
</presyntaxhighlight></big>
Line Cursor Position; this variable keeps track of which line of text the cursor is on. _lcurpos is zero, if the cursor is on the fist line appearing in the Border.
<big><presyntaxhighlight lang="cpp">
int _loffset;
</presyntaxhighlight></big>
Offset Of the First Line; this variable keeps track of which line is the first appearing in the border. _loffset is zero, if the first string (line) of the string array is appearing on the fist line of the Border.<br /><br />
'''_lcurpos''' and '''_loffset''' have the same responsibility as _curpos, and _offset, but only for lines of the text. So as the left and right scrolling is done by manipulating _offset and _curpos, up and down scrolling of lines in the text are done by manipulating '''_loffset''' and '''_lcurpose'''

Works exactly like the previous constructor, but also it will call the '''set''' method of FWText to split the incoming text ('''Str''') at newline characters into an array of strings.
<big><presyntaxhighlight lang="cpp">
void draw(int Refresh = FW_NO_REFRESH)const;

Converts the newline delimited array of characters (the text) into an array of strings.<br />
Set starts with the first string in the array of strings and copies the characters of the array to the current string until it reaches a newline character. <br />
Then it will null terminate the current string and go to the next string in the array of strings and repeats the same over and over until it reaches the end of the text.
:''Note that if '''FW_MAX_LINE_CHARS''' is reached before getting to the newline character, the current string is null terminated and copying continues into the next one''. <big><presyntaxhighlight lang="cpp">
void *data();
</presyntaxhighlight></big>
Converts the array of strings, back to a single string of text and returns it.<br />
'''data()''' first calculates the size of the whole text including the newline characters at the end of each line. Then it will allocated enough memory to hold it all.<br /> Finally, it will concatenate all the strings back into the allocated memory adding a newline character to the end of each of them and returns it. <big><presyntaxhighlight lang="cpp">
int edit();
</presyntaxhighlight></big>
Draws the text area and then starts the editing from the fist line.<br />
The whole text should scroll to left, write, up or down instead, if the cursor tries to pass the edges of the text area.<br />
When Backspace key is hit at the beginning of the line, the content of the current line should be moved to the previous line, the and current line should be deleted. The cursor in this case should stand in front of the copied data. <br />
:''Note that this will not happen if the sum of the length of the current and previous lines are more than FW_MAX_LINE_CHARS''
