wxGlade has the ability to integrate custom or 3rd party widgets into its pallette. This feature is not documented very well. By using some sample code from Alberto Griggio and digging through the core-widgets source code, I was able to create bridge code that adds Andrea Gavana’s FloatSpin control to the pallette. For those that follow, I suggest starting with the a similar class from the core pallette and the code for html_window. The only real gotcha for this integration was that the widget container was not seeing KILL FOCUS events from the FloatSpin controls and therefore changed data was not saved. This was fixed by trapping EV_FLOATSPIN events and calling the update.
The FloatSpin bridge code is installed by untarring from within your .wxglade directory. The included README contains more details.
