written on windows 7 using python 3.6.2, should work on any platform,
but not tested on Linux or OS-X
I've been doing a lot of playing around with wxpython for the past few weeks.
I needed a reliable routine that could distinguish between single and double
mouse clicks.
There is a good timer example in the demos that come with the wxpython phoenix
tarball, and I used this as the basis for this routine.
Here's how it works:
when a EVT_LEFT_DOWN event is triggered, the timer is started
if another left click down event is triggered (recognized as a EVT_LEFT_DCLICK),
the timer is stopped because, it's no longer needed, this is a double click.
After 250ms EVT_TIMER event occurs, that means that the full 250ms elapsed and the
event must be a single click. The timer is stopped and right click can be processed.
Here's the code:

Here's how it works:
- wx.EVT_LEFT_DOWN is bound to on_left_down
- wx.EVT_LEFT_DCLICK is bound to on_dbl_click
- wx.EVT_TIMER is bound to single_click
when a EVT_LEFT_DOWN event is triggered, the timer is started
if another left click down event is triggered (recognized as a EVT_LEFT_DCLICK),
the timer is stopped because, it's no longer needed, this is a double click.

event must be a single click. The timer is stopped and right click can be processed.
