Defines the graphic used to display a leaf item's plus/minus graphic.

Deprecated - Provided for compatibility with earlier versions only - Use Items.PlusMinusImageLeaf instead

Syntax

Get

VB.NETrefPictureObj = object.PlusMinusPictureLeaf As System.Drawing.Image
VBSet refPictureObj = object.PlusMinusPictureLeaf As IPictureDisp
C#.NETSystem.Drawing.Image refPictureObj = object.PlusMinusPictureLeaf;
VC++IPictureDisp* refPictureObj = object->GetPlusMinusPictureLeaf();
CHRESULT object->get_PlusMinusPictureLeaf(IPictureDisp** refPictureObj);

Put

VB.NETobject.let_PlusMinusPictureLeaf(ByVal refPictureObj As System.Drawing.Image)
VBobject.PlusMinusPictureLeaf = refPictureObj As IPictureDisp
C#.NETvoid object.let_PlusMinusPictureLeaf(System.Drawing.Image refPictureObj);
VC++void object->PutPlusMinusPictureLeaf(IPictureDisp* refPictureObj);
CHRESULT object->put_PlusMinusPictureLeaf(IPictureDisp* refPictureObj);

PutRef

VB.NETobject.PlusMinusPictureLeaf = refPictureObj As System.Drawing.Image
VBSet object.PlusMinusPictureLeaf = refPictureObj As IPictureDisp
C#.NETSystem.Drawing.Image object.PlusMinusPictureLeaf = refPictureObj;
VC++void object->PutRefPlusMinusPictureLeaf(IPictureDisp* refPictureObj);
CHRESULT object->putref_PlusMinusPictureLeaf(IPictureDisp* refPictureObj);

object

A SftTree object.

refPictureObj

Defines the graphic used to display a leaf item's plus/minus graphic. The ref PictureObj object must represent a bitmap and cannot represent an icon or a metafile. The top, left pixel of each graphic must contain the background color. This color will be replaced by the actual background color when the graphic is displayed. For information about picture properties, please visit the applicable section "Using SftTree/OCX with ...".

Comments

Deprecated - Provided for compatibility with earlier versions only - Use Items.PlusMinusImageLeaf instead

The PlusMinusPictureLeaf property defines the graphic used to display a leaf item's plus/minus graphic.

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

The PlusMinusPictureLeaf property is used to define the plus/minus graphic displayed for an item which doesn't have any dependents. All items which don't have any dependents will be displayed with this plus/minus graphic. Individual items cannot override the plus/minus graphic.

Plus/minus graphics are not shown until the properties Items.PlusMinusImageExpandable and Items.PlusMinusImageExpanded define valid graphics. The PlusMinusImageLeaf property is optional.

All graphics used in a tree control as Items.PlusMinusImageExpandable, Items.PlusMinusImageExpanded and PlusMinusImageLeaf 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 plus/minus graphics are never clipped vertically. To change the plus/minus graphic size, the plus/minus graphics properties Items.PlusMinusImageExpandable, Items.PlusMinusImageExpanded and PlusMinusImageLeaf must be set to the value Nothing (NULL) before assigning new plus/minus graphics.

If an item is disabled (see Item.Enabled property), the plus/minus 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 PlusMinusPictureLeaf property can be set to the value Nothing (NULL). Plus/minus graphics are then no longer displayed for leaf items.

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.
