Tree Control I Directive

Syntax

%I= Image_List %

Argument	Type	Description
Image_List	C	A CR-LF delimited list of the names of one or more bitmap images.

Description

The I directive specifies image used in a tree control. To use images in a tree control, you specify the list of images to use in the format string (i.e. between the % ….% delimiters in the control definition. When you have multiple directives in a Format string, you separate them with semi-colons ";".

Before any entry on a tree that contains an image, add a number, which corresponds to the number of the image in the Image_Choices.

If a different bitmap is displayed when a branch of a tree is open, use an optional '+' followed by the number of the image to show when the branch is open. for the open dialog. A Comma should be placed after the prefix image number. [Picture]
