Syntax       

Get

VB.NET

Handle = object.ItemPictureLeafH  As Integer

VB

Handle = object.ItemPictureLeafH  As OLE_HANDLE

C#.NET

int Handle = object.ItemPictureLeafH;

VC++

OLE_HANDLE Handle = object->ItemPictureLeafH;
OLE_HANDLE Handle = object->GetItemPictureLeafH();

C

HRESULT object->get_ItemPictureLeafH(OLE_HANDLE* Handle);

Delphi

Handle := object.ItemPictureLeafH  : Cardinal;

Put

VB.NET

object.ItemPictureLeafH = Handle  As Integer

VB

object.ItemPictureLeafH = Handle  As OLE_HANDLE

C#.NET

int object.ItemPictureLeafH = Handle;

VC++

OLE_HANDLE object->ItemPictureLeafH = Handle;
void object->PutItemPictureLeafH(OLE_HANDLE Handle);

C

HRESULT object->put_ItemPictureLeafH(OLE_HANDLE Handle);

Delphi

object.ItemPictureLeafH := Handle  : Cardinal;

object

A SftTree object.

Handle

A bitmap handle.  Defines the default graphic used to display a leaf item's item graphic.  This bitmap handle has to remain valid until the tree control no longer uses it.  The application has to destroy the bitmap handle once it is no longer needed.  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.

The ItemPictureLeafH property defines the default graphic used to display a leaf item's item graphic.

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

The ItemPictureLeafH property is used to define the default item graphic displayed for an item which doesn't have any dependentsItem graphics are not shown until the properties Items.ItemImageExpandable, Items.ItemImageExpanded and Items.ItemImageLeaf define valid graphics.

When using fixed height items (see Items.Style), all graphics used in a tree control as Item.Image, 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 item graphics 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 ItemPictureLeafH property can be set to the value 0 (NULL).  Item graphics are then no longer displayed.  The Item.Image properties remain unchanged.

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.
