Usage
When you add a small picture to a ListView control, it is
given the next available picture index in the ListView. For example,
if your ListView has two pictures, the next picture you add will
have index number 3.
Before you add small pictures, you can specify scaling for
the pictures by setting the SmallPictureWidth and SmallPictureHeight
properties. The dimensions in effect when you add the first picture
determine the scaling for all pictures. Changing the property values
after you add pictures has no effect.
If you do not specify values for SmallPictureWidth and SmallPictureHeight before
you add pictures, the dimensions of the first image determine the
scaling for all pictures you add.
Before you call AddSmallPicture, specify
the color in the bitmap that will be transparent by setting the
SmallPictureMaskColor property. You can change the SmallPictureMaskColor
property between calls.
Examples
This example adds the file “shortcut.ico” to the
small picture index of the ListView lv_files:
|
1 |
//Add small picture |
|
1 |
integer index |
|
1 |
index = lv_files.<span>AddSmallPicture</span>("shortcut.ico") |
