Defines the graphic used to display an expandable item's plus/minus graphic. The refPictureObj 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 ...".
The PlusMinusPictureExpandable and PlusMinusPictureExpandableH properties are synonyms, but accept different value types (Picture object reference or Windows bitmap handle).
All graphics used in a tree control as Items.PlusMinusImageExpandable, Items.PlusMinusImageExpanded and Items.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 Items.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 PlusMinusPictureExpandable property can be set to the value Nothing (NULL). Plus/minus graphics are then no longer displayed.
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.
