Title: wx2.9.5 Patch for wxWidgets - Contrib Items wx2.9.x
Post by: stahta01 on August 17, 2013, 11:11:04 pm

I have found an compile bug/design changed issue caused by wxWidgets 2.9.5

Example Compiler Error

Code

src\plugins\contrib\wxContribItems\wxchart\src\legendwindow.cpp|34|error: no 'wxObject* wxLegendWindow::wxCreateObject()' member function declared in class 'wxLegendWindow'|

Reason seems to be the use of wxWidgets Macro DECLARE_CLASS when the correct Macro is DECLARE_DYNAMIC_CLASS in the header file.
It is needed if IMPLEMENT_DYNAMIC_CLASS is used in the source file.

Can an C++ and wxWidgets expect confirm this is correct?

Patch below; it compiles with wxWidgets 2.9.5; but, no other testing has been done.

I just stumbled across the same issue.
I just committed the fix.

In wx2.8 DECLARE_CLASS and DECLARE_DYNAMIC_CLASS are the same, while in wx2.9 they differ.
The dynamic classes implement a static wxCreateObject function, which is not declared by DECLARE_CLASS.

...I already have a patch pending for this - it just needs testing....
