Summary0004076: Cool Extension to JvDocking (alpha blended form dragging)
DescriptionWith JvDocking when you drag a dock form a rectangular is painted directly on the Desktop using PatBlt (same as Delphi docking). This is highly problematic with Windows Vista when using the Aero theme (very slow even with a good graphics card). In Vista, you are strongly discouraged to write directly to the desktop. If you have noticed BDS uses instead an alpha blended rectangular form which works fine with Windows Vista and looks much better.

The attached modified JvDocking files implement such a feature in JvDocking. All modifications to the files (quite minimal) are inside
so they are very easy to see. I could provide diff files if needed.

Also the modifications resolve a bug in JvDocking according to which the dragged form impage is not painted correctly when dragged over a TabControl with the TabPosision set to tpTop.

To test the extensions:
- Copy the files to the jvcl\run directory
- Play with the AdvancePro JvDocking demo

Additional InformationCould someone please have a look and commit the other submitted patches to JvDocking in reports 3958, 4020, 3998 and 3989? These patches resolve long outstanding issues with JvDocking.

Please provide patch files, it makes integration MUCH easier especially when other changes have been made in between. Use TortoiseSVN to create the patch files as it makes merging much easier for us. Thanks.
