ListView sort column's order at runtime

Post by gfilatov » Fri Aug 15, 2008 9:46 am

Hello All,

Just idea for a next HMG build below:

Code: Select all

/*
 * MiniGUI Grid Demo
 * (c) 2005 Roberto Lopez
 *
 * ListView SORT ORDER COLUMN 
 * Author: BADIK <badik@mail.ru>
*/

#include "minigui.ch"

Memvar fColor

Function Main

Local aRows [20] [3]

	Private fColor := { || if ( This.CellRowIndex/2 == int(This.CellRowIndex/2) , { 0,0,255 } , { 0,255,0 } ) }	

	DEFINE WINDOW Form_1 ;

				SEPARATOR
				MENUITEM 'Exit'				ACTION Form_1.Release
			END POPUP
		END MENU

		aRows [1]	:= { 113.12,date(),1,1 , .t. }
