STX B+ Tree Demo Program

Summary

This demonstration program draws illustrations of the B+ trees constructed by the STX B+ Tree template classes. The demo allows the user to selected different types of B+ tree instantiations: integer or string keys and different slot numbers. The user may insert and erase key/data pairs from the tree and run different search operations. The demo program uses the cross-platform wxWidgets toolkit and can be compiled on Linux, Windows and MacOSX.

Download Binaries

Pick the binary built on the operating system closest to your running system. Beware that the dynamically linked Linux binaries will only work on distributions with similar library naming rules.

If the following demo binaries do not work, you can try older downloads, because all patches to the btree source code are not relevant for the demo. The B+ tree was always correct, and thus the demo was as well.

Program Usage

The easiest way to see how the demo functions is by pressing "Insert Random" and selecting 10 pairs from the popup menu. These random number pairs are then shown in the B+ tree illustration.

The operation buttons perform their respective functions on the B+ tree with the key/data input given in the two edit fields. The operation's result is printed into the text line below the buttons.

The B+ tree drawing can be scrolled using the scrollbars and zoomed using the mouse wheel (on Windows this requires the drawing to be activated by a click).
