Hi All,
Below is a sample of a wx.ScrolledPanel. The vertical grid has 25
wx.TextCtrl fields.
Is there ANY way to automatically (by pressing a button) move the
scroll so the 10th field is the first one visible? The 20th field?
And back to the 0th field. I just want to save the user time
scrolling and possibly passing the field they want. Maybe this is an
enhancement request but it seems like a feature wx.ScrolledPanel could
use if it does not already have it.
