I have 4 spinctrls in my app. When I click on them, I want all their 
content to be selected instantly. And another thing is, I need to make 
them tab traversal. Can you help me with some sort of code to do this 
task? 
Thanks in advance.
You need to catch EVT_SPIN or EVT_SPINCTRL and in your handler, you can select all the values by calling each of the control's GetValue method. In the wxPython demo, it seems to support tab traversal. I'm not sure what's going on with yours. Did you try the FloatSpin widget as an alternative?
Make Spinctrl selected when activated in WxPython
