A bitmap handle. Defines the graphic used to display an expanded item's plus/minus 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 PlusMinusPictureExpanded and PlusMinusPictureExpandedH 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 PlusMinusPictureExpandedH property can be set to the value 0 (NULL). Plus/minus graphics are then no longer displayed.
