ListView_DeleteColumns Method

Description

This method will delete the columns specified in a list in the ListView control.

Parameters

MyControlReference: Reference to the control in the form of MyProject_MyForm_MyControl.
ProjectFile: String identifying the project as it was passed in LoadProject.
DialogName: String identifying the dialog by name.
ControlName: String identifying the control by name.
nColIndexX: Integer specifying the Xth column to delete.

Return Values

Returns the following according to the situation:

T when successful.
Nil if the control is not found or does not support this function.

AutoLISP Syntax

The recommended convention is passing the control identifier directly:

Copy Code
(Odcl_ListView_DeleteColumns MyControlReference [as Reference] (list nColIndex1 [as Integer] nColIndex2 [as Integer] nColIndex3 [as Integer] ... nColIndexN [as Integer] ) )

An alternative convention is to identify the control by providing the project file, the dialog name and the control name:

Copy Code
(Odcl_ListView_DeleteColumns ProjectFile [as String] DialogName [as String] ControlName [as String] (list nColIndex1 [as Integer] nColIndex2 [as Integer] nColIndex3 [as Integer] ... nColIndexN [as Integer] ) )

Copy Code

(Odcl_ListView_DeleteColumns
		ProjectFile [as String]
		DialogName [as String]
		ControlName [as String]
		(list 
			nColIndex1 [as Integer]
			nColIndex2 [as Integer]
			nColIndex3 [as Integer]
			...
			nColIndexN [as Integer]
		)
	)

Remarks

Please create lists as follows using the list keyword:

(list (list x y ...) (list x y ...) ...)

It seems that ObjectARX does not always handle lists created as follows:

'(x y ...) (x y ...) ...

Applies For

ListView.

Example

Copy Code
; Delete the second and third column (Odcl_ListView_DeleteColumns MyProject_MyForm_MyControl (list 2 1) )
