Hi,
I use a draw widget with motion events turned on, I've noticed that a double
click event has a different y-position to a single click event. This is
demonstrable by the code at the bottom of this message. For a double click,
the events returned give:
X Y
Cursor position = 187 110
Cursor position = 187 110
Cursor position = 187 111
Cursor position = 187 110
It is easy to work around the problem by detecting the double click
(event.clicks = 2) and subtracting 1 from event.y
I can recreate the problem on another computer of almost identical
specification to my own. I am using IDL 5.3.1 on NT 4. Can anybody recreate
this bug and on what platforms?
Regards,
Oliver Smith
PRO DRAW_EVENT, event
Print, 'Cursor position = ', Event.x, Event.y
END
PRO ojs
base = Widget_Base(UNAME = 'WID_BASE', SCR_XSIZE=300 ,SCR_YSIZE=200)
draw = Widget_Draw(Base, UNAME = 'WID_DRAW',SCR_XSIZE = 300, SCR_YSIZE =
200, /BUTTON_EVENTS, EVENT_PRO = 'DRAW_EVENT')
Widget_Control, /REALIZE, base
Xmanager, 'WID_BASE', base, /NO_BLOCK
END

I've sent a message to UK support.
No reply as yet (other than acknowledgement).

Hi Oliver, Martin
On my W2K, IDL 5.3.1 I got SSDD (Same Shit Different Day)...
To be 100% correct not every time...
Cursor position = 96 151
Cursor position = 96 151
Cursor position = 96 152
Cursor position = 96 151
Cursor position = 96 151
Cursor position = 96 151
Cursor position = 96 152
Cursor position = 96 151
Cursor position = 96 151
Cursor position = 96 151
Cursor position = 96 151
Cursor position = 96 151
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 150
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 150
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 150
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 150
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 150
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 150
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 150
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 149
Cursor position = 162 149
As you see 3/12=25% of the coorect behaviour. I am using MS IntelliMouse
Explorer USB mouse, if this info helps you... It was done with "ordinary
care";
for "supergentle pressing" the results are differnt
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
Cursor position = 63 144
12/12 = 100%
So I think driver-mouse sensitivity is the key to your question...

I am seeing the same problem in IDL 5.2 on WinNT SP4.
The Y value is always one more on the release that indicates a double-click.

I'm certain I'm not moving the mouse. The final y value (2nd release event)
is the same as the first two, so the mouse would have to move for the second
press, then move back to the original position for the second release. I
don't see the cursor move at all on the screen.
As for the coffee theory, I do have one of those oversized RSI mugs....
Can anybody else running IDL 5.x under NT recreate this? (see original post
for code).
Regards,
Oliver
