Display Images In A Grid

• Step 1 - Declare global variables in <yourform>.classdeclaration

public class FormRun extends ObjectRun

{

    Imagelist imageList;

    Image image;

}

• Step 2 - Create Image List in <yourForm>.init

public void init()

{

    imageList = new ImageList(ImageList::smallIconWidth(), ImageList::smallIconHeight());

    image = new Image();

    image.loadResource(1030);  // tick icon

    imagelist.add(image);

    image.loadResource(927); // info icon

    imageList.add(image);

    image.loadResource(928); // warning icon

    imageList.add(image);

    image.loadResource(929); // red x icon

    imageList.add(image);

    super();

    

}

• Step 3 - Create a window field on the grid

Set the AutoDeclaration of the window field to yes in the properties dialog

Load the image list to the window in <yourForm>.init after the super();

public void init()

{

    imageList = new ImageList(ImageList::smallIconWidth(), ImageList::smallIconHeight());

    image = new Image();

    image.loadResource(1030); 

    imagelist.add(image);

    image.loadResource(927);

    imageList.add(image);

    image.loadResource(928);

    imageList.add(image);

    image.loadResource(929);

    imageList.add(image);

    super();

    <windowField>.imageList(imageList);

}

• Step 4 - Create method to set image on window field

On the table that is driving the grid, add a display method to set the picture in the window field.

The picture set is the data item in the array, not the icon number

public client server display int setIcon()

{

    #define.TickIcon(0)

    #define.InfoIcon(1)

    #define.WarningIcon(2)

    #define.StopIcon(3)

    

    if(!InventTable::find(this.itemNumber))

    {

        return #StopIcon;

    }

    else if(this.qtyOnHand() <= 0)

    {

        return #WarningIcon;

    }

    return #TickIcon;

}

• Step 5 - Link window field to data

On the properties of the window field to point to the data method in step 4

DataSource  = <table in step 4>

DataMethod = <display method in step 4>
