Line Annotation Object

 

The line annotation object (ANNOBJECT_LINE) is a simple line. With the automated functions, the line is started on a mouse-down event and completed on a mouse-up event.

The class for Line Annotation objects is LAnnLine.

With low-level functions, you must provide the points that define the line. Other applicable properties have the following defaults, which you can change:

Visible

Defaults to FALSE. It can be changed using the LAnnotation::SetVisible function.

Selected

Defaults to FALSE. It can be changed using the LAnnotation::SetSelected function.

Name

Defaults to an empty string. It can be changed using the LAnnotation::SetNameOptions function.

Line width

Defaults to 0.75 points. It can be changed using the LAnnLine::SetLineWidth function. (Note that when displayed, the line must have a minimum width of 1 pixel.)

Line style

Defaults to solid. It can be changed using the LAnnLine::SetLineStyle function.

ROP2 code

Defaults to ANNROP2_COPY. It can be changed using the LAnnotation::SetROP2 function.

Foreground color

Defaults to red. It can be changed using the LAnnLine::SetForeColor function.

Fixed State

Defaults to not fixed. It can be changed using the LAnnXXX::SetFixed function.

Hyperlink

Defaults to ANNLINK_NONE. It can be changed using the LAnnotation::SetHyperlink function.

Tag (identifier)

Defaults to 0. It can be changed using the LAnnotation::SetTag function.

Window handle

Defaults to NULL or the handle inherited from the container.

User mode

Defaults to design mode or the mode inherited from the container.

Note: You can not create a line of two points which they are the same.
