I would like to create a dialog box which pops up when the user click on a button from a Python Add-In toolbar.
The user will navigate to their preferred file and select any shapefiles they wish to add to ArcMap.
I found this code:
import Tkinter, tkFileDialog
root = Tkinter.Tk()
root.withdraw()
file_path = tkFileDialog.askopenfile()
but the dialog box is ALMOST opening and then ArcMap crashes.
Since you're using a python addin, you could use the pythonaddins.OpenDialog method.
Slightly modified example based on the documentation:
This add-in button uses OpenDialog() to select a set of layer files and adds each layer to the selected data frame.
import arcpy
import pythonaddins
class AddLayers(object):
def __init__(self):
self.enabled = True
self.checked = False
def onClick(self):
layer_files = pythonaddins.OpenDialog('Select Layers', True, r'C:\GISData', 'Add')
mxd = arcpy.mapping.MapDocument('current')
df = mxd.activeDataFrame
for dataset in datasets:
layer = arcpy.mapping.Layer(dataset)
arcpy.mapping.AddLayer(df, layer)
