Virtual Treeview is a Delphi treeview control built from ground up. Many years of development made it one of the most flexible and advanced tree controls available today. Virtual Treeview starts off with the claim to improve many aspects of existing solutions and introduces some new technologies and principles which were not available before.

Help Needed: Any volunteer that takes care about C++ Builder bugs and packages?

I don't use C++ Builder and my experience with it is very limited. This makes it difficult to take care about bugs that are reported in C++ Builder and to maintain the C++ Builder packages. I would be great if someone would volunteer to do this.

Reporting Bugs

First of all, please make sure you are using the latest official version. When reporting a bug please attach a sample project as ZIP-file that allows us to quickly reproduce the bug. This can also be one of the demo projects that come with Virtual Treeview, modified to show the bug. If only small changes are required, a description is sufficient how a demo projects needs to be changed in order to replicate the bug. Please follow best practices for good bug reports.

If you already have a solution, please supply a patch file or make a pull request. If you used a previous version that did not have the bug, please include this version number in your report.

Feature Requests

We currently focus on reducing the number of reported bugs and getting Virtual Treeview stable. Feature Requests will most likely not processed at the moment. We are only going to process enhancement requests if the new feature is of general interest and a source code patch based on the latest SVN revision is attached to the report. Please mark feature requests with the flag "Enhancement".


If you want to contribute, you are welcome. We always look for help, not only for the development of the Virtual Treeview control itself, but also for maintaining the sample projects, the help or the wiki. Please send an email to: joachim(dot)marder(a)
