Tech Note 03i: ImageList Object

January 5, 2007

For more information on this control, see Microsoft's documentation.

This control contains a collection of images to which you can refer by index. Use as a central repository to conveniently supply other controls, such as TabStrip, ListView, and TreeView, with images. The number of images that you can load is limited by the amount of available memory.

This control has been replaced by NSBControls.dll.

Here is some documention, thanks to Heiko Stolte:

Syntax

AddObject "ceimagelist.imagelistctrl.1", "ImageList1",0,0,0,0

Where Imagelist1 is the name of the object.

Properties

HImageList	Pointer to Imagelist
Count	Number of pictures
Imagewidth*	Width of Imagelist = width of first picture
Imageheight*	Height of Imagelist = height of first picture

* all other pictures will be resized to first picture size

Methods

Add pathfilename	Adds an image to imagelist Important: picture colors*
Remove index	Remove pictures number
RemoveAll	Removes all pictures
Replace index, pathfilename	Replace picture number index with picture filename
Reset	Resets imagelist

* I tested with 256 colors, that works fine

Example (see MSCEListview sample)

AddObject "ceimagelist.imagelistctrl.1","ImageList1",0,0,0,0
AddObject "ceimagelist.imagelistctrl.1","ImageList2",0,0,0,0
AddObject "listviewctrl.listviewctrl.1","listView",10,130,220,120
