Hi Jai, That did the trick! Thanks very much, it works like a charm, and doesn't even need threading. All the best, Jelmer

Hi Jai, thanks for your reply. I'm currently not using any other GUI framework than ArcGIS itself, using the python add-in wizard: https://www.arcgis.com/home/item.html?id=5f3aefe77f6b4f61ad3e4c62f30bff3b And by using a while loop in the code the tool and ArcGIS hangs. Here is a simple snippet example: import arcpy import pythonaddins class ButtonClass1(object): """Implementation for tryaddin_addin.button (Button)""" def __init__(self): self.enabled = True self.checked = False def onClick(self): # the while loop global switch while switch == 0: print 1 global switch class ButtonClass2(object): """Implementation for tryaddin_addin.button_2 (Button)""" def __init__(self): self.enabled = True self.checked = False def onClick(self): # turn off the while loop global switch switch = 1 switch = 0

As far as I've seen online I can answer my question: the answer is no.

I'm building a python add-in for ArcGIS desktop with a button which runs a while loop. Another button should close the while loop. In the while loop there is a continuous process going on which is important for the functionality of the add-in. But unfortunately the while loop causes the add-in, and therefore ArcGIS desktop, to hang. I have tried time.sleep(.1) in the while loop. And I have tried the threading library. But nothing seems to work. I was hoping someone maybe had a suggestion? Thanks in advance!

I wasn't planning to use these data driven pages, but if they solve my problem I will of course. I'm merely interested to find out if there is an event listener available which triggers once a user zooms/pans the map.

I'm trying to make a python add-in application extension which triggers once the map view extent has changed. But none of these functions seem to work: ArcGIS Help 10.1 Is this still possible?

I was able to solve the error. I changed: layer = arcpy.mapping.Layer('C:\path\shapefile.shp') symbologylayer = arcpy.mapping.Layer('C:\path\symbologylayer.lyr') arcpy.ApplySymbologyFromLayer_management(layer, symbologylayer) Into: layer = arcpy.mapping.Layer('C:\path\shapefile.shp') arcpy.ApplySymbologyFromLayer_management(layer, 'C:\path\symbologylayer.lyr') The former code worked only on my PC, the latter code works on all PCs checked so far.

An ArcGIS 10.2 layerfile can be read by ArcGIS 10.1 Hi Xander, That was what I was trying to find out. If this is true then something else must cause the error. The add-in works in 10.2 and there the data types match. The symbology layer is the .lyr file and the other layer I make on-the-fly using arcpy. I will need to wait until I can debug on 10.1. Thanks for your reply, Jelmer

I'm working on a python add-in which includes a .LYR file with specific symbology. I use ApplySymbologyFromLayer_management to load a shapefile with this .LYR symbology in the ArcMap TOC. This works perfectly on my own testing PC with ArcGIS 10.2. But when I ask a test user to try the add-in on ArcGIS 10.1 the following error is returned: ExecuteError: Failed to execute. Parameters are not valid. ERROR 000968: The symbol layer does not match the input layer Failed to execute (ApplySymbologyFromLayer). I can't easily debug this problem on the test user system and therefore, as a first step, I would like to find out if a .LYR file made in 10.2 should be backwards compatible with 10.1? Thanks in advance!

Thanks! That did the trick! I needed to set self.enabled and self.editable to True.

Using self.value it is possible to preset the value of the combo box (one of the values in the self.items list). But this value is not shown when the add-in is first loaded, you still see a blank combo box, even after self.refresh(). How can I show the selected value? This is not the most important functionality, but I think it would make the add-in I'm working on more easily understood by users.

Hi Jeff, I added the code you suggested but then ArcMap 10 crashes... Jelmer

Hello, I have two raster layers in my TOC of which the top one is semitransparent. They have the same size and extent. I would like to export this combined 'map' in it's full resolution. My first attempt uses File > Export Map. First I set the Dataframe width to be the rasters width. Next in Export Map I increase the DPI until the exported image width is around the width of the rasters. When I export ArcGIS 10 SP3 crashes. This has worked for me with ArcGIS 9.3. The second attempt is using python: import arcpy mxd = arcpy.mapping.MapDocument("mymxd.mxd") outTIFFpath = "out.tif" df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0] arcpy.mapping.ExportToTIFF(mxd, outTIFFpath, df, df_export_width=46070, df_export_height=28126, resolution=2642, world_file=True, geoTIFF_tags=True) (the width of the rasters is 46080 and 46070 here is the best approximation I can get) The problem here is that the exported TIFF isn't correctly georeferenced. The resulting map is mostly white 'nodata' around the raster. How can I make sure the MapDocument goes to full extent before I export? Kind regards, Jelmer Oosthoek
