The exact thin I want to do is retrieve the moose coordinates when I click
on a map.
The way I use actually is :
Create a ToolButton, calling 'mycallback'
then
Sub mycallback
Dim x,y As Float
x = CommandInfo(CMD_INFO_X)
y = CommandInfo(CMD_INFO_Y)
nb_found = SearchPoint(-,-,x,y)
s_table = SearchInfo(----)
.... Then enumerate the results.....
End Sub
But this method is not very nice, because the user MUST first click on the
ToolButton, each time before clicking on the map.

Hi Christophe,
short and direct example not possible I think, but should know if you want
use this feature in your own application you should use "callback". you can
find detailed information in MapBasic's help - Integrated Mapping section.
Note: to get continuously the mouse coordinates and to get coordinate of
clicked point is two different things. In an integrated application MapInfo
able to communicate to your application through callback. E.g. MI
continously able to send status text to your application, from it you will
able to pick-up actual coordinate and display it on your form's statusbar
for example.(As you move the cursor on map coordinates will display in your
form's statusbar) On the same way when you click on a map MI send info
(throught callback) to your application which will/can include x,y clicked
then you can pick them up and display.
Hope this helps a bit
regards

Subject: MI-L Follow Mouse Coordinates with Mapbasic
Hi
I would like to display continuously the mouse coordinates, to know exactly
the cursor position when I click on a map.
At 06/21/2004, B. Thoen talked about XMouse tool, written by Robert Edwards
few years ago.
He specified too a list of Windows API used to do that, like ClientToScreen,
GetClientRect, GetCursorPos....
Does someone know more about that ?
Thank you - Chris
