This is true and in the specific case of triple click, wx does indeed report them to the application differently than gtk does. This doesn't, to my knowledge, interfere with text controls that don't try to handle the click, but it may result in inconsistent behavior with an app that adds triple click behavior to it's own text controls. > > wxPython (as opposed to wxWidgets, the C++ core) has a sizeable library > > of custom controls as part of its standard lib.

The differences are orders of magnitude in severity. One common problem is that people use incorrect (but working on Windows) code and don't test under linux, it can cause similar issues. The *toolkit* is very strong on all platforms. Individual apps are often much less strong, because relatively view developers have access and motivation to test heavily on all platforms. wx tries to make correct code work the same on all platforms, but it can't make incorrect code fail the same way on all platforms. And, of course, many people simply aren't familiar with or choose not to use the APIs that wx provides for whatever reason. Custom controls that don't use native fonts are fairly common, for example, even though wx provides APIs to retrieve the correct fonts and the use of them is encouraged - people just hardcode whatever they "know" the right font is on their native platform. -- http://mail.python.org/mailman/listinfo/python-list
