Updates to Common Controls

The improvements to standard controls in the VCL of Delphi 2009 are extremely important because they are also related with commonly used controls like edits and buttons. The new version of the VCL also includes many enhancements to other controls provided by the Windows API since the move to the 32-bit version of the operating system. Here are some controls that have new features:

  • ImageList: Although not every single developer will benefit from this, the ImageList component now supports alpha-blended images and lets you set a custom color depth, using a new property with the corresponding name (ColorDepth).
  • TreeView: Another component with limited updates in the past is the TreeView, which now lets you define an image index for expanded nodes and (on Windows XP or later) support disabled tree nodes.
