Usage
When you add a large picture to a ListView, 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 be assigned picture index
number 3.
Before you add large pictures, you can specify scaling for the
pictures by setting the LargePictureWidth and LargePictureHeight
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 LargePictureWidth and
LargePictureHeight before you add pictures, the dimensions of the first
image determine the scaling for all pictures you add.
When you add a bitmap, specify the color in the bitmap that will be
transparent by setting the LargePictureMaskColor property before calling
AddLargePicture. You can change the LargePictureMaskColor property between
calls.
Examples
This example adds the file “folder.ico” to the large picture index
of the ListView lv_files:
|
1 2 3 |
// Add large picture integer index index = lv_files.AddLargePicture("folder.ico") |
