NAME¶
XmTextReplace — A Text function that replaces part of a text
string "XmTextReplace" "Text functions"
"XmTextReplace"
SYNOPSIS¶
#include <Xm/Text.h>
void XmTextReplace(
Widget widget,
XmTextPosition from_pos,
XmTextPosition to_pos,
char * value);
DESCRIPTION¶
XmTextReplace replaces part of the text string in the Text widget. The
character positions begin at 0 (zero) and are numbered sequentially from the
beginning of the text.
An example text replacement would be to replace the second and third characters
in the text string. To accomplish this, the parameter
from_pos must be
1 and
to_pos must be 3. To insert a string after the fourth character,
both parameters,
from_pos and
to_pos, must be 4.
This routine calls the widget's
XmNvalueChangedCallback and verification
callbacks, either
XmNmodifyVerifyCallback or
XmNmodifyVerifyCallbackWcs, or both. If both verification callback
lists are registered, the procedures of the
XmNmodifyVerifyCallback
list are executed first and the resulting data is passed to the
XmNmodifyVerifyCallbackWcs callbacks. The
XmNmotionVerifyCallback is generated if
to_pos is less than or
equal to the cursor position and the length of
value is not the same as
the length of the text being replaced, or if the cursor position is between
from_pos and
to_pos, and the distance from the cursor position
to
from_pos is greater than the length of
value.
