Mouse enter/leave events of a frame
Andy Wu
Hi,
I'm having a problem with mouse enter/leave events. I am trying to write
a frame that automatically close it self if the mouse has left the
window for a while. However, I can't bind the event to the frame if the
frame has child panels which usually is the case. The panels cover the
frame so mouse enter/leave event of the frame will never trigger.
I tried to make all children of the frame posting the events to the
frame by calling wx.PostEvent in their event handling function, but this
will trigger the events when moving the mouse across different panels of
the frame and they cannot have their own handlers anymore.
Is there a solution for this? I mean, a frame's MouseEnter/MouseLeave
events are always called as long as the mouse is in the area if the
frame no matter what kind of children the frame is holding.
Many thanks
Andy

Thanks Federico.
That means you customized every windows in your frame? I wonder if you
can just have a customized frame and be free to add any kind of widgets
you want. If that is impossible, I guess I'll have to customized
everything in the frame.

I know this is a very rudimentary solution, and I'm sure someone will
chip in with a solid solution involving the event handler.
I had a similar problem a while ago, and since it was for a minor set
of controls with the identical number and type of childrens (just 3
staticbitmaps and a statictext), what I did was to have all 4 four
windows (panel and childrens) to set/unset each one a particular bit
in a bitmask whenever there was an Enter_Window or Leave_Window event.
If the bitmask dropped to zero, then I knew they were not involved
with the position of the mouse.

not know anything about mouse move in/out as they will probably have
their own event handler on these events.
Your idea seems fine...I'm thinking about the same thing minutes ago, I
will go this way most likely.
Thanks for helping!

Unfortunately, yes, I had to to subclass everything. Mind you, they
all were to begin with, as I was drawing a fancy tab with alpha
blending.
It's not a very good solution for larger problems, tough, some ideas:
Does it have to exit the frame inmediatly upon leaving the app's area?
Otherwise you can rig a Timer to periodically call the static method
wx.GetMousePosition() and compare the results against the area covered
by your frame. Get a rect of the frame with GetClientRect(), offset it
by an (x,y) tuple as provided by [frame].ClientToScreen((0,0)), and
then check if the mouse position is inside the rect, (Offset and
Inside in wx.Rect will be very useful).

My real code will look a little different because I close the frame by fading it out. But thanks a lot for sharing this.

How about using a timer and checking to see it the mouse is inside the frame or outside the frame?
You will have to make sure that the mouse starts inside the frame or... implement some kind of a trigger mechanism
Like this:
import wx
class CustomFrame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None)
self.armed = False
self.t1 = wx.Timer(self)
self.t1.Start (100)
self.Bind(wx.EVT_TIMER, self.OnTimer)
def OnTimer(self, evt):
mouse_pos = wx.GetMousePosition()
frame_pos = self.GetPosition()
frame_size = self.GetSize ()
rect = wx.Rect(frame_pos[0], frame_pos[1], frame_size[0], frame_size[1])
if rect.Inside(mouse_pos) and not self.armed:
self.armed = True
print "Mouse captured. If the mouse leaves the frame it will die!"
elif not rect.Inside(mouse_pos) and self.armed:
print "I've warned you! Now the frame died!"
self.Close()
app = wx.App(0)
frame = CustomFrame()
frame.Show()
app.MainLoop()
