TComboBoxExStrings.Move Method

Changes the position of a string in the list.

Pascal

procedure Move(CurIndex: Integer; NewIndex: Integer); override;

C++

virtual __fastcall Move(int CurIndex, int NewIndex);

Description

Use Move to move the string at position CurIndex so that it occupies the position NewIndex. The positions are specified as 0-based indexes. For example, the following lines of code move the string in the first position to the last position.

Copy Code

MyStringsObject.Move(0, MyStringsObject.Count

Copy Code

MyStringsObject->Move(0, MyStringsObject->Count - 1);

If the string has an associated object, the object remains associated with the string in its new position.
