Routines / Setting the Caret and Selection Range

TESetSelect

The TESetSelect procedure sets the selection range within the text of the specified
edit record.

PROCEDURE TESetSelect (selStart, selEnd: LongInt; hTE: TEHandle); 

selStart

The byte offset at the start of the text selection range.

selEnd

The byte offset at the end of the text selection range.

hTE

A handle to the edit record.

DESCRIPTION

The TESetSelect procedure removes highlighting of the old selection range and highlights the new one. If selStart equals selEnd, the new selection range is an insertion point, and a caret is displayed. If selEnd is anywhere beyond the last character of the text, TESetSelect uses the first position past the last character. The selEnd and selStart fields can range from 0 to 32767.

SPECIAL CONSIDERATIONS

When only the Roman script system is used, the selection range is always displayed and highlighted as a continuous range of text. However, when one or more script systems requiring mixed-directional display of text are installed, a continuous sequence of characters in memory may appear as a discontinuous selection when displayed.
