Hi,
It’s my first time to use sizers manually (based on code generated by wxGlage).
Alas, I’m not able to set a button to a fixed distance from the right edge of a frame.
I have the below frame, where I want the “Cancel” button to appear exactly below the “Find” button.
(“Cancel” needs to be relative to the right edge, because the width of from_row_combo_box changes in my real application).
However, even after reading http://www.wxpython.org/docs/api/wx.Sizer-class.html and various examples on the web, I still am unable to find the right combination of flags that will place the “Cancel” button under the “Find” button.
Has anyone experience with sizers, and can point me in the right direction ?
Thanks,
Ron.
