Hi, I'm having issuses while developing a new addin - it seems that ALL mouse event handlers (except onMouseMove[Map]), doesn't work / blocked when I draw a line in on the map. I really need that functionality, since my tool need to ignore certain points on the polyline, indicated by ctrl+left mouse click. Does anybody knows how can I get thouse events while drawing a line? Thanks, Yoav. P.S: There's a code example: class DrawLine ( object ) : """Implementation for SomeToolExample.drawline (Tool)""" def __init__ ( self ) : self . enabled = False self . shape = "Line" def onMouseDown ( self , x , y , button , shift ) : # This DOESN'T work (blocked?) while a drawing a line pass def onMouseDownMap ( self , x , y , button , shift ) : # This DOESN'T work (blocked?) while a drawing a line pass def onMouseUp ( self , x , y , button , shift ) : # This DOESN'T work (blocked?) while a drawing a line pass def onMouseUpMap ( self , x , y , button , shift ) : # This DOESN'T work (blocked?) while a drawing a line pass def onMouseMove ( self , x , y , button , shift ) : # This is working while a drawing a line pass def onMouseMoveMap ( self , x , y , button , shift ) : # This is working while a drawing a line pass def onDblClick ( self ) : pass def onKeyDown ( self , keycode , shift ) : # This DOESN'T work (blocked?) while a drawing a line pass def onKeyUp ( self , keycode , shift ) : # This DOESN'T work (blocked?) while a drawing a line pass def deactivate ( self ) : pass def onLine ( self , line_geometry ) : # Main Logic here, not important for this example pass

onMouseDownMap event with Line shape - Addin Tool

Hi,

I'm having issuses while developing a new addin - it seems that ALL mouse event handlers (except onMouseMove[Map]), doesn't work / blocked when I draw a line in on the map.

I really need that functionality, since my tool need to ignore certain points on the polyline, indicated by ctrl+left mouse click.

Does anybody knows how can I get thouse events while drawing a line?

Thanks,

Yoav.

P.S: There's a code example:

A simple print doesn't work. Of course, I want an array like you said, but the event is blocked by the line drawing (doesn't even print the x, y of onMouseDownMap). That's the issue I'm having.

RandyBurton

What code have you tried with the onMouseDownMap? Just 'pass'? Don't know if something like this would work, but have you tried saving the onMouseDownMap x, y, button and shift data in an array, and then checking the array when onLine is triggered?

YoavAbadi

Hi Randy,

Yes, I read that, as you see, this code uses None shape, and i need the mouse events to work while in line shape event.

Do you hace a solution to that?

Yoav.

RandyBurton

There is an example of onMouseDownMap on this page: How To: Capture map coordinates with a mouse click using Python

YoavAbadi

Yes, but that's what i have to do.. 😕

Thanks, Yoav.

I don't use arcobjects… my preference would be a right-click on a selection rather than trying to skip stuff during a drawing process

YoavAbadi

Do you know if there is something like that in arcobjects, in case illI have to rewrite everything in c# for skipping a point?

I want just the coords of the points whike there been drawn 😕

DanPatterson_Retired

They need some more specific examples I suppose, but the way I read it, nothing will happen and no functions are called until the line is drawn first. There doesn't seem to be any example of drawing a line and skipping points

YoavAbadi

Hi Mark,

Thanks for replying.

What do you mean by following?

I did read all the documentations and every existing post here/gis-stockexcstock before I posted this .

But, i didn't see anywhere a mention about one event blocking the other.

I did see that by using None shape, you can utilize the on events handlers, but as I mentioned above, I must have a line drawing while using them 😕

I you have any idea what to do, it will be much appreciated!

Yoav.
