Thanks! I was missing the step of storing an attribute for each independent variable and doing something in the event handler to change the menu items from checked to unchecked. Your samples allowed me to get my first custom context menu working! It’s good enough for what I was hoping to accomplish. Thank you again for all of your help!
Below is the code that worked for me. Note: Rhino 6, (6.7.18190.21071, 07/09/2018). GH python component in SDK mode.
from ghpythonlib.componentbase import executingcomponent as component
from System.Windows.Forms import ToolStripSeparator
import Grasshopper, GhPython
import System
import Rhino
import rhinoscriptsyntax as rs
import math
import fractions
class decFtConverter(component):
def __init__(self):
super(decFtConverter,self).__init__()
self.factor = 1
self.checked1 = False
self.checked2 = False
self.checked3 = False
def RunScript(self,decIn):
if self.factor == 1:
ftIn = decIn
self.Message = "Make a Choice"
else: ftIn = self.feet_inches(decIn)
return ftIn
def feet_inches(self,decimal):
tol = round(decimal * self.factor)
b = math.modf(tol / self.factor)
feet = int(b[1] // 12)
inch = int(b[1] % 12)
fract = fractions.Fraction(b[0])
if fract == 0:
fract = ""
fi= str(feet)+"'- "+str(inch)+" "+str(fract)+'"'
return fi
def AppendAdditionalMenuItems(self, items):
try: #always everything inside try
#context menu item 1
component.AppendAdditionalMenuItems(self, items)
image = None
items.Items.Add(ToolStripSeparator())
item = items.Items.Add("Round to 1/2", image, self.OnClicked1)
item.ToolTipText = "Round 1/2";
item.Name = "2";
item.Checked = self.checked1
#context menu item 2
item = items.Items.Add("Round to 1/4", image, self.OnClicked2)
item.ToolTipText = "Round 1/4 ";
item.Name = "4";
item.Checked = self.checked2
#context menu item 3
item = items.Items.Add("Round to 1/8", image, self.OnClicked3)
item.ToolTipText = "Round 1/8";
item.Name = "8";
item.Checked = self.checked3
except Exception, ex:
System.Windows.Forms.MessageBox.Show(str(ex))
def OnClicked1(self, index, value):
try: #always everything inside try
self.checked1 = not self.checked1
self.checked2 = False
self.checked3 = False
self.factor = int(index.Name)
self.Message = (index.ToolTipText)
self.ExpireSolution(True)
except Exception, ex:
System.Windows.Forms.MessageBox.Show(str(ex))
def OnClicked2(self, index, value):
try: #always everything inside try
self.checked2 = not self.checked2
self.checked1 = False
self.checked3 = False
self.factor = int(index.Name)
self.Message = (index.ToolTipText)
self.ExpireSolution(True)
except Exception, ex:
System.Windows.Forms.MessageBox.Show(str(ex))
def OnClicked3(self, index, value):
try: #always everything inside try
self.checked3 = not self.checked3
self.checked1 = False
self.checked2 = False
self.factor = int(index.Name)
self.Message = (index.ToolTipText)
self.ExpireSolution(True)
except Exception, ex:
System.Windows.Forms.MessageBox.Show(str(ex))
