NAME

DtEditorChange — change one or all occurrences of a string in a DtEditor widget

SYNOPSIS

#include &<Dt/Editor.h>
Boolean DtEditorChange(
Widget widget,
DtEditorChangeValues *findChangeStrings,
unsigned int instanceToChange);

DESCRIPTION

The DtEditorChange function replaces the next occurrence of a string, all occurrences of the string, or the currently selected text in a DtEditor widget with a replacement string. The string to search for and the value to change it to can be the last values entered in the Find/Change dialog (see DtEditorInvokeFindChangeDialog(3)) or passed as arguments to DtEditorChange.

The search begins at the insertion cursor. If the string is not found by the time the end of the document is reached, the search continues at the beginning of the document, stopping at the character before the insertion cursor.

The widget argument specifies the DtEditor widget ID.

The findChangeStrings argument specifies the string to change and the replacement value. If findChangeStrings is NULL, DtEditorChange uses the last string specified in the Find and Change To fields of the Find/Change dialog. If the instanceToChange argument is DtEDITOR_CURRENT_SELECTION, the Find field of DtEditorChangeValues is ignored.

If the instanceToChange argument is set to DtEDITOR_NEXT_OCCURRENCE, DtEditorChange replaces the next occurrence (relative to the insertion cursor) of the find string. If this argument is set to DtEDITOR_ALL_OCCURRENCES, all instances of the find string are changed. If this argument ia set to DtEDITOR_CURRENT_SELECTION, the Find field of DtEditorChangeValues, is ignored and the currently selected text is replaced.

RETURN VALUE

Upon successful completion, the DtEditorChange function returns True if the substitution occurred; otherwise, it returns False.
