TCustomComboBox.SelStart property
zero-based index to the UTF-8 character at the beginning of the
selected text in the edit box.
Declaration
property SelStart: Integer read GetSelStart write SetSelStart;Description
If text is selected in the edit box for the control, this is the starting position. When no text is selected, SelStart is the cursor position and SelLength is 0 (zero).
Writing a new value to the property moves the cursor, and removes the current text selection. Set SelLength after changing SelStart, to establish a new text selection.
SelStart is a zero-based index to UTF-8 character in the Text, in contrast to the usual 1-based string indices. The value 0 means the first UTF-8 character, the value 1 means the second UTF-8 character, etc.
