DtEditorInsertFromFile(library call) DtEditorInsertFromFile(library call) NAME
DtEditorInsertFromFile -- insert data from a file into a DtEditor widget SYNOPSIS
#include <Dt/Editor.h> DtEditorErrorCode DtEditorInsertFromFile( Widget widget, char *fileName); DESCRIPTION
The DtEditorInsertFromFile function inserts data from a file to the insertion cursor position in a DtEditor widget. After the data is inserted, the insertion cursor is positioned after the last character inserted. The widget argument specifies the DtEditor widget ID. The fileName argument is the pathname of the file relative to the local system. For a complete definition of the DtEditor widget and its associated resources, see DtEditor(3). RETURN VALUE
Upon successful completion, the DtEditorInsertFromFile function returns one of the following values: DtEDITOR_NO_ERRORS The file is readable and writable. DtEDITOR_READ_ONLY_FILE The file is read only. DtEDITOR_NULLS_REMOVED The file contained embedded NULL characters, which were removed. Otherwise, if it cannot insert the data into the DtEditor widget, DtEditorInsertFromFile returns one of the following values: DtEDITOR_NONEXISTENT_FILE The file does not exist. DtEDITOR_DIRECTORY The file is a directory. DtEDITOR_CHAR_SPECIAL_FILE The file is a character-special device. DtEDITOR_BLOCK_MODE_FILE The file is a block-mode device. DtEDITOR_NO_FILE_ACCESS The file cannot be accessed. DtEDITOR_INSUFFICIENT_MEMORY Not enough system memory is available to insert the file. DtEDITOR_UNREADABLE_FILE The file is unreadable for an unspecified reason. APPLICATION USAGE
If the data is in memory, rather than a disk file, the application should use DtEditorInsert(3). SEE ALSO

DtEditorReplace(library call) DtEditorReplace(library call) NAME
DtEditorReplace -- replace a portion of the contents of a DtEditor widget SYNOPSIS
#include <Dt/Editor.h> DtEditorErrorCode DtEditorReplace( Widget widget, XmTextPosition startPos, XmTextPosition endPos, DtEditorContentRec *data); DESCRIPTION
The DtEditorReplace function replaces part of the contents of a DtEditor widget with a string, a wide character string or sized buffer. The data is transferred to the DtEditor widget using a DtEditorContentRec, which indicates the type of data being transferred along with the actual data. All data following the start position and up to, but not including, the end position is replaced. If the start position and the end position are equal, the data is inserted after the end position. The character positions begin at zero and are numbered sequentially from the beginning of the text. After the replacement, the insertion cursor is positioned after the last character inserted. The widget argument specifies the DtEditor widget ID. The startPos argument specifies the starting character position of the portion to replace. The replacement begins at this character. The endPos argument specifies the ending character position of the portion to replace. The replacement ends before this character. The data argument is a pointer to the data structure containing the data to insert. For a complete definition of the DtEditor widget and its associated resources, see DtEditor(3). For a complete definition of DtEditorContentRec, see Dt/Editor.h - DtEditor(5). RETURN VALUE
Upon successful completion, the DtEditorReplace function returns one of the following values: DtEDITOR_NO_ERRORS The data was replaced sucessfully. DtEDITOR_NULLS_REMOVED NULL characters were found and removed from the data. Otherwise, if the DtEditorReplace function cannot replace the data in the DtEditor widget, it returns one of the following values: DtEDITOR_INVALID_TYPE The Type field is not recognized. DtEDITOR_INVALID_RANGE The startPos argument is greater than the endPos argument. DtEDITOR_ILLEGAL_SIZE The size of the buffer passed in is negative. DtEDITOR_NULL_ITEM The data buffer is NULL. DtEDITOR_INSUFFICIENT_MEMORY Not enough system memory is available to replace the data. EXAMPLES
The following code segment modifies the contents of a DtEditor widget to ``The quick fox.'' Widget editor; DtEditorContentRec cr; DtEditorErrorCode status; XmTextPosition start = (XmTextPosition) 4, end = (XmTextPosition) 9; char *sampleString1="The brown fox", *sampleString2="quick"; cr.type = DtEDITOR_TEXT; cr.value.string = sampleString1; status = DtEditorSetContents(editor, &cr); if (status != DtEDITOR_NO_ERRORS && status != DtEDITOR_NULLS_REMOVED) { printf("Unable to set contents of the widget "); } else { cr.type = DtEDITOR_TEXT; cr.data.string = sampleString2; status = DtEditorReplace(editor, start, end, &cr); if (status != DtEDITOR_NO_ERRORS) printf("Unable to replace part of the widget contents "); } APPLICATION USAGE
If the data is in a disk file, rather than in memory, the application should use DtEditorReplaceFromFile(3). SEE ALSO
