Mouse motion example - help

Desktop wxRuby
1

Hi,
I am trying out this example adapted from the wxpython book, but the
mouse motion event does not seem to be captured right. What am I doing
wrong?

Thanks
warrior

code below

require ‘wx’

class MyFrame < Wx::Frame
def initialize
super(nil, -1, “My Frame”, :size => [300,300])
@my_panel = Wx::Panel.new(self, -1)
evt_motion(){ |event| on_move(event)}
Wx::StaticText.new(@my_panel, -1, :label => “Pos:”, :pos => [10,
12])
@posCtrl = Wx::TextCtrl.new(@my_panel, -1, “”,:pos => [40, 10])
show
end

def on_move(event)
@pos = event.get_position
@posCtrl.change_value("#{@pos}")
end
end
Wx::App.run{MyFrame.new}

The mouse movement event is directed to the topmost window. So you
either need to specify that mouse events are captured by the Frame, or
call the event handler upon the panel which is topmost.

If you think this is different to wxPython, could you post/point to the
example you mention please?

code below

require ‘wx’

class MyFrame < Wx::Frame
def initialize
super(nil, -1, “My Frame”, :size => [300,300])
@my_panel = Wx::Panel.new(self, -1)
evt_motion(){ |event| on_move(event)}

Either:

@my_panel.evt_motion { | e | on_move(e) }

or

capture_mouse
evt_motion :on_move

Wx::App.run{MyFrame.new}

Thanks, your suggestion worked. I missed out on the fact that I had to
bind the mouse motion to the panel and not to MyFrame. So,
@my_panel.evt_motion worked exactly as needed.
