form library +.Sh LIBRARY +.Lb libform +.Sh SYNOPSIS +.In form.h +.Ft int +.Fn form_driver "FORM *form" "int request" +.Sh DESCRIPTION +The +.Fn form_driver +is the heart of the forms library, it takes commands in the +.Fa request +parameter that is either a request to the driver to perform some +action or is a character to be inserted into the current field. +The form driver will attempt to insert any printable character passed to +it into the current field. +This may or may not succeed depending on the state of the current field. +If the character passed is not +printable then the driver attempts to process it as a driver request. +If the character passed is not a valid request then the driver will +return an unknown command error. +.Sh PARAMETERS +The forms driver recognizes the following requests: +.Pp +.Bl -tag -width REQ_SFIRST_FIELD -compact +.It REQ_NEXT_PAGE +Change to the next page in the form. +.It REQ_PREV_PAGE +Change to the previous page in the form. +.It REQ_FIRST_PAGE +Select the first page in the form. +.It REQ_LAST_PAGE +Go to the last page in the form. +.It REQ_NEXT_FIELD +Move to the next field in the form field array. +.It REQ_PREV_FIELD +Move to the previous field in the form field array. +.It REQ_FIRST_FIELD +Go to the first field in the form field array. +.It REQ_LAST_FIELD +Go to the last field in the form field array. +.It REQ_SNEXT_FIELD +Move to the next sorted field on the form. +.It REQ_SPREV_FIELD +Move to the previous sorted field on the form. +.It REQ_SFIRST_FIELD +Go to the first field in the sorted list. +.It REQ_SLAST_FIELD +Move to the last field in the sorted list. +.It REQ_LEFT_FIELD +Go one field to the left on the form page. +.It REQ_RIGHT_FIELD +Go one field to the right on the form page. +.It REQ_UP_FIELD +Go up one field on the form page. +.It REQ_DOWN_FIELD +Go down one field on the form page. +.It REQ_NEXT_CHAR +Move one char to the right within the field +.It REQ_PREV_CHAR +Move one char to the left within the current field. +.It REQ_NEXT_LINE +Go down one line in the current field. +.It REQ_PREV_LINE +Go up one line in the current field. +.It REQ_NEXT_WORD +Go forward one word in the current field +.It REQ_PREV_WORD +Go backward one word in the current field. +.It REQ_BEG_FIELD +Move the cursor to the beginning of the current field. +.It REQ_END_FIELD +Move the cursor to the end of the current field. +.It REQ_BEG_LINE +Move the cursor to the beginning of the line in the current field. +.It REQ_END_LINE +Move the cursor to the end of the line. +.It REQ_LEFT_CHAR +Move the cursor left one character +.It REQ_RIGHT_CHAR +Move the cursor right one character +.It REQ_UP_CHAR +Move the cursor up one line. +.It REQ_DOWN_CHAR +Move the cursor down one line. +.It REQ_NEW_LINE +Insert a new line at the current cursor position. +.It REQ_INS_CHAR +Insert a blank character at the current cursor position +.It REQ_INS_LINE +Open a blank line at the current cursor position. +.It REQ_DEL_CHAR +Delete the character at the current cursor position. +.It REQ_DEL_PREV +Delete the character to the left of the current cursor position. +.It REQ_DEL_LINE +Delete the current line. +.It REQ_DEL_WORD +Delete the word at the current cursor position. +.It REQ_CLR_EOL +Clear the field from the current cursor position to the end of the +current line. +.It REQ_CLR_EOF +Clear the field from the current cursor position to the end of the field. +.It REQ_CLR_FIELD +Clear the field. +.It REQ_OVL_MODE +Enter overlay mode, characters added to the field will replace the +ones already there. +.It REQ_INS_MODE +Enter insert mode, characters will be inserted at the current cursor +position. +Any characters to the right of the cursor will be moved +right to accommodate the new characters. +.It REQ_SCR_FLINE +Scroll the field forward one line. +.It REQ_SCR_BLINE +Scroll the field backward one line. +.It REQ_SCR_FPAGE +Scroll the field forward one field page. +.It REQ_SCR_BPAGE +Scroll the field backward one field page. +.It REQ_SCR_FHPAGE +Scroll the field forward half one field page. +.It REQ_SCR_BHPAGE +Scroll the field backward half one field page. +.It REQ_SCR_FCHAR +Scroll the field horizontally forward one character +.It REQ_SCR_BCHAR +Scroll the field horizontally backward one character +.It REQ_SCR_HFLINE +Scroll the field horizontally forward one field line. +.It REQ_SCR_HBLINE +Scroll the field horizontally backward one field line. +.It REQ_SCR_HFHALF +Scroll the field horizontally forward half a field line. +.It REQ_SCR_HBHALF +Scroll the field horizontally backward half a field line. +.It REQ_VALIDATION +Request the contents of the current field be validated using any field +validation function that has been set for the field. +Normally, the field is validated before the current field changes. +This request allows the current field to be validated. +.It REQ_PREV_CHOICE +Select the previous choice in an enumerated type field. +.It REQ_NEXT_CHOICE +Select the next choice in an enumerated type field. +.El +.Sh RETURN VALUES +Functions returning pointers will return +.Dv NULL +if an error is detected. +The functions that return an int will return one of the following error +values: +.Pp +.Bl -tag -width E_UNKNOWN_COMMAND -compact +.It Er E_OK +The function was successful. +.It Er E_REQUEST_DENIED +The forms driver request could not be fulfilled +.It Er E_UNKNOWN_COMMAND +The passed character is not a printable character and is not a valid +forms driver request. +.It Er E_BAD_ARGUMENT +A bad argument was passed to the forms driver. +.It Er E_INVALID_FIELD +The form passed to the driver has no valid attached fields. +.It Er E_NOT_POSTED +The given form is not currently posted to the screen. +.It Er E_BAD_STATE +The forms driver was called from within an init or term function. +.It Er E_INVALID_FIELD +The character passed to the forms driver fails the character +validation for the current field. +.El +.Sh SEE ALSO +.Xr curses 3 , +.Xr forms 3 +.Sh NOTES +Field sorting is done by location of the field on the form page, the +fields are sorted by position starting with the top-most, left-most +field and progressing left to right. +For the purposes of sorting, the +fields top left corner is used as the sort criteria. +The header +.In form.h +automatically includes both +.In curses.h +and +.In eti.h . |
