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:
// Add large picture
integer index
index = lv_files.AddLargePicture("folder.ico")See also
