object

A SftTree object.

ItemIndex

The zero-based item index.

refPictureObj

Defines the graphic displayed as the item's item graphic. The refPictureObj object must represent a bitmap, icon or Windows metafile. If a bitmap is used, the top, left pixel of each graphic must contain the background color. This color will be replaced by the actual background when the graphic is displayed. For information about picture properties, please visit the applicable section "Using SftTree/OCX with ...".

The ItemPicture property defines the graphic displayed as the item's item graphic.

The ItemPicture and ItemPictureH properties are synonyms, but accept different value types (Picture object reference or Windows bitmap handle).

The ItemPicture property is used to override the default item graphic defined using the Items.ItemImageExpandable, Items.ItemImageExpanded and Items.ItemImageLeaf properties. These default graphics must be defined for item graphics to be shown.

The ItemPicture property can be set before the default graphics have been defined using the Items.ItemImageExpandable, Items.ItemImageExpanded and Items.ItemImageLeaf properties, but item graphics are not shown until these default graphics are defined.

When using fixed height items (see Items.Style), all graphics used in a tree control as ItemPicture, Items.ItemImageExpandable, Items.ItemImageExpanded and Items.ItemImageLeaf properties at the same time must be the same size (height and width). The dimensions of the graphics are used to calculate the minimum dimension for items, so graphics used as ItemPicture property are never clipped vertically. To change the item graphic size, all item graphics must be removed first using the Items.ClearItemImages method.

When using variable height items (see Items.Style), the graphics used can be of varying size. The item height is adjusted automatically, so graphics are never clipped vertically.

If an item is disabled (see Item.Enabled property), the graphic is drawn in a "grayed" fashion, if it is based on a bitmap. Other image types, like color samples, .NET image objects, etc., must be explicitly replaced with a grayed image if a different rendering of a disabled image is desired.

The ItemPicture property can be set to the value Nothing (NULL), which restores the default graphic.

The Items.ItemImageAlign property can be used to align item graphics on lower levels with higher level cells.

The VAlignStyle property can be used to define the vertical alignment of item graphics.

Using PutRef (see Syntax above) the control will use the reference to the Picture object. If the Picture object is later changed, this will also affect the image used by the control. Using Put instead causes the control to create a copy of the Picture object. If the Picture object is later changed, this will not affect the image used by the control as it uses a copy of the object. Because of the additional overhead and the increased resource use of Put, PutRef is the preferred method.
