custom slider and register events

wxPython Users
1

This is my try for creating custom widget. I am trying to create a custom slider. It’s working fine but I am not able to set wx.CommandEvent for
various stats(LEFT_UP, LEFT_DOWN, MOTION etc.)

I have used wx.PyPanel for making the slider. Is it OK? or what ever I have done, I mean look wise can be done If I subclass wx.Slider for making
a custom slider

Thanks

Hello,

  1. When constructing an event object you need to pass an event type (i.e wx.wxEVT_, not wx.EVT_),

See line 80 in your sample.

  1. You are rebinding EVT_LEFT_UP in your Frame and not skipping the event so it doesn’t propagate down to your other handler inside your slider class.

  2. I think you want to check for HasCapture instead of GetCapture.

Cody,

Does every Event (e.g., wx.EVT_*) have an EventType analog (e.g.,
wx.wxEVT_*) If so, where do I find them?

I'm trying to create a Notebook event for a unittest, but
wx.wxEVT_NOTEBOOK_PAGE_CHANGED doesn't appeart to exist.

Cody,

wx.wxEVT_*) If so, where do I find them?

I’m trying to create a Notebook event for a unittest, but
wx.wxEVT_NOTEBOOK_PAGE_CHANGED doesn’t appeart to exist.

If they are a command event (notebook commands are) they typically are as follows

wx.wxEVT_COMMAND_*

Most/all events should have an associated event type though they are not always named in a predictable manner. I am sure they are in the documentation somewhere. But I typically just do something like the following in a python shell to find what I am looking for,

for x in dir(wx):

if ‘NOTEBOOK_PAGE_CHANGED’ in x:

print x

You should see a wxEVT_COMMAND_NOTEBOOK_PAGE_CHANGED in there

Regards,

Cody

If you don't care what the actual name of the eventType is then there is a shortcut to get the value using the binder object. They have a typeId property that returns the value. As you can see here it is the same as the wxEVT_* version:

  >>> import wx
  >>> wx.EVT_NOTEBOOK_PAGE_CHANGED.typeId
  10125
  >>>
  >>> wx.wxEVT_COMMAND_NOTEBOOK_PAGE_CHANGED
  10125
  >>>

Some events are composites of other events, (EVT_MOUSE_EVENTS and EVT_SCROLL for example) so there is also another attribute that is a list of eventType ID values:

  >>> wx.EVT_NOTEBOOK_PAGE_CHANGED.evtType
  [10125]
  >>> wx.EVT_SCROLL.evtType
  [10055, 10056, 10057, 10058, 10059, 10060, 10061, 10062, 10063]
