- This is a test program for the TBmpListBox and TBmpComboBox
- components. See BMPLBOX.PAS for details and documentation.
-
- You mmust install the components in BMPLBOX.PAS before running
- this sample program.
-
- The "Color" button shows you how the TransparentColor property
- works. When you click on it, the property switches between blue
- and red. This shows you that the selected color becomes transparent
- when the listbox or combobox item is displayed.
-
- The "Margin" button demonstrates that the gap between the text
- and the bitmap can be dynamically adjusted. This margin also
- applies to the left of the bitmap.
-
- Also, observe how the glyph index is passed to AddObject. The HiWord
- of the pseudo TObject reference is used to pass the glyph index and
- you can use the LoWord for your own needs. You can associate any glyph
- from the bitmap strip to any item in the list.
-
- Since you have access to Items.Objects[i], you can change this value
- dynamically.
-
- Have fun!
