Description


The SizingGrip class makes it possible to show a small sizing grip bitmap in the lower right corner of dbViews and dbModalPanels.

This way users will know when they can resize a panel.

Usage



Unzip the file `SizingGrip.Zip' to your projects directory. It will create a workspace directory SizingGrip.
To view the example program that comes with this package, you first need to register the workspace.
Click on the file `Classes.VDFGuidance.SizingGrip.ws' in the Programs directory to register the workspace in VDF 8.x.

Then start the ide and open the program `Example'.
Compile and run the program to see what's happening.

Special thanks to Wil van Antwerpen for sharing his cvBitmapContainer class which makes it possible
to use transparent bitmaps.
Don't forget to take a closer look at his vWin32fh.pkg package as well. It contains a collection of file
