CVI에서 컨트롤을 동적으로 생성하기



CVI에서 동적으로 컨트롤을 생성하는 방법이다.

일반적인GUI프로그램에서 사용하고자 하는 컨트롤을 Panel에 미리 배치해놓고 작업을 하게 된다.
하지만 경우에 따라 버튼을 클릭한다거나 했을 때 동적으로 panel에 생성할 필요가 있을 때가 있다.

이 때 LabWindows/CVI에서 사용할 수 있는 함수가 NewCtrl()함수이다.

인자로 panel핸들, 컨트롤의 스타일, 컨트롤의 label, 위치(상, 좌)가 있고, int형의 컨트롤 ID를 반환한다.

NewCtrl

int NewCtrl (int panelHandle, int controlStyle, char controlLabel[], int controlTop, int controlLeft);

Purpose

Creates a new control and returns a control ID that you can use to specify the control in subsequent function calls.
If you call this function to add a timer control to a panel, you must do so in the same thread in which you create or load the panel.

Parameters
