This routine has + three major input cases: + + <STRONG>o</STRONG> The input is a form navigation request. Navigation + request codes are constants defined in <STRONG><form.h></STRONG>, which + are distinct from the key- and character codes + returned by <STRONG>wgetch</STRONG>. + + <STRONG>o</STRONG> The input is a printable character. Printable charac- + ters (which must be positive, less than 256) are + checked according to the program's locale settings. + + <STRONG>o</STRONG> The input is the KEY_MOUSE special key associated with + an mouse event. + + The form driver requests are as follows: + + REQ_NEXT_PAGE + Move to the next page. + + REQ_PREV_PAGE + Move to the previous page. + + REQ_FIRST_PAGE + Move to the first page. + + REQ_LAST_PAGE + Move to the last field. + + + REQ_NEXT_FIELD + Move to the next field. + + REQ_PREV_FIELD + Move to the previous field. + + REQ_FIRST_FIELD + Move to the first field. + + REQ_LAST_FIELD + Move to the last field. + + REQ_SNEXT_FIELD + Move to the sorted next field. + + REQ_SPREV_FIELD + Move to the sorted previous field. + + REQ_SFIRST_FIELD + Move to the sorted first field. + + REQ_SLAST_FIELD + Move to the sorted last field. + + REQ_LEFT_FIELD + Move left to a field. + + REQ_RIGHT_FIELD + Move right to a field. + + REQ_UP_FIELD + Move up to a field. + + REQ_DOWN_FIELD + Move down to a field. + + + REQ_NEXT_CHAR + Move to the next char. + + REQ_PREV_CHAR + Move to the previous char. + + REQ_NEXT_LINE + Move to the next line. + + REQ_PREV_LINE + Move to the previous line. + + REQ_NEXT_WORD + Move to the next word. + + REQ_PREV_WORD + Move to the previous word. + + REQ_BEG_FIELD + Move to the beginning of the field. + + REQ_END_FIELD + Move to the end of the field. + + REQ_BEG_LINE + Move to the beginning of the line. + + REQ_END_LINE + Move to the end of the line. + + REQ_LEFT_CHAR + Move left in the field. + + REQ_RIGHT_CHAR + Move right in the field. + + REQ_UP_CHAR + Move up in the field. + + REQ_DOWN_CHAR + Move down in the field. + + + REQ_NEW_LINE + Insert or overlay a new line. + + REQ_INS_CHAR + Insert a blank at the cursor. + + REQ_INS_LINE + Insert a blank line at the cursor. + + REQ_DEL_CHAR + Delete character at the cursor. + + REQ_DEL_PREV + Delete character before the cursor. + + REQ_DEL_LINE + Delete line at the cursor. + + REQ_DEL_WORD + Delete blank-delimited word at the cursor. + + REQ_CLR_EOL + Clear to end of line from cursor. + + REQ_CLR_EOF + Clear to end of field from cursor. + + REQ_CLR_FIELD + Clear the entire field. + + REQ_OVL_MODE + Enter overlay mode. + + REQ_INS_MODE + Enter insert mode. + + + REQ_SCR_FLINE + Scroll the field forward a line. + + REQ_SCR_BLINE + Scroll the field backward a line. + + REQ_SCR_FPAGE + Scroll the field forward a page. + + REQ_SCR_BPAGE + Scroll the field backward a page. + + REQ_SCR_FHPAGE + Scroll the field forward half a page. + + REQ_SCR_BHPAGE + Scroll the field backward half a page. + + + REQ_SCR_FCHAR + Scroll the field forward a character. + + REQ_SCR_BCHAR + Scroll the field backward a character. + + REQ_SCR_HFLINE + Horizontal scroll the field forward a line. + + REQ_SCR_HBLINE + Horizontal scroll the field backward a line. + + REQ_SCR_HFHALF + Horizontal scroll the field forward half a line. + + REQ_SCR_HBHALF + Horizontal scroll the field backward half a line. + + + REQ_VALIDATION + Validate field. + + REQ_NEXT_CHOICE + Display next field choice. + + REQ_PREV_CHOICE + Display previous field choice. + + If the second argument is a printable character, the + driver places it in the current position in the current + field. If it is one of the forms requests listed above, + that request is executed. + + <STRONG>MOUSE</STRONG> <STRONG>HANDLING</STRONG> + If the second argument is the KEY_MOUSE special key, the + associated mouse event is translated into one of the above + pre-defined requests. Currently only clicks in the user + window (e.g., inside the form display area or the decora- + tion window) are handled. + + If you click above the display region of the form: + + a REQ_PREV_FIELD is generated for a single click, + + a REQ_PREV_PAGE is generated for a double-click and + + a REQ_FIRST_FIELD is generated for a triple-click. + + If you click below the display region of the form: + + a REQ_NEXT_FIELD is generated for a single click, + + a REQ_NEXT_PAGE is generated for a double-click and + + a REQ_LAST_FIELD is generated for a triple-click. + + If you click at an field inside the display area of the + form: + + <STRONG>o</STRONG> the form cursor is positioned to that field. + + <STRONG>o</STRONG> If you double-click a field, the form cursor is + positioned to that field and <STRONG>E_UNKNOWN_COMMAND</STRONG> is + returned. This return value makes sense, because a + double click usually means that an field-specific + action should be returned. It is exactly the pur- + pose of this return value to signal that an appli- + cation specific command should be executed. + + <STRONG>o</STRONG> If a translation into a request was done, + <STRONG>form_driver</STRONG> returns the result of this request. + + If you clicked outside the user window or the mouse event + could not be translated into a form request an + <STRONG>E_REQUEST_DENIED</STRONG> is returned. + + <STRONG>APPLICATION-DEFINED</STRONG> <STRONG>COMMANDS</STRONG> + If the second argument is neither printable nor one of the + above pre-defined form requests, the driver assumes it is + an application-specific command and returns <STRONG>E_UNKNOWN_COM-</STRONG> + <STRONG>MAND</STRONG>.
