Ok, I now risk being kicked out from this list for spamming :D but I have to take my chances. Btw: I'm still waiting for a bung of WPF books to arrive, so, please bear with me.
Here's a primitive app I'm trying to build in VS2010 using IPy and, to me, the new WPF stuff. XAML and the Python Code attached. Now, when I try to build the app, I get an error: "Event addition expected callable object, got NoneType" Can anyone explain to me why I'm getting this error? As I said, I'm more used to WinForms and adding a function definition to a control this way has always worked. Even more so as I copied some of the code, incl. the evenaddition from this site: http://www.ironpython.info/index.php/XAML_GUI_Events_Example
Thank you very much (again) in advance, I really do appretiate all your support. Lukáš Duběda Director [T] +420 602 444 164 duber studio(tm) [M] [email protected] [W] http://www.duber.cz [A] R.A.Dvorského 601, Praha 10 [A] 10900, Czech Republic, Europe niki wrote:
