Hello, i want to add button “disable/enable solver” , which loaded automatically when Grasshopper started.
How i can fix this code to make it work?

using Grasshopper;
using Grasshopper.Kernel;

namespace DisableSolver
{
    public class DisableSol
    {

        public static void CustomizeUI()
        {

            if (Instances.DocumentEditor.Controls[0].Controls[1] is System.Windows.Forms.ToolStrip toolbar)
            {
                var SolverButton = new System.Windows.Forms.ToolStripButton("Disable")
                {
                    ToolTipText = "Disable Solver"
                };
                SolverButton.Click += (s, e) =>
                {
                    if (GH_Document.EnableSolutions == true)
                    {
                        if (SolverButton.ToolTipText == "Disable Solver")
                        {
                            GH_Document.EnableSolutions = false; 
                        }
                    }
                    else if (GH_Document.EnableSolutions == false)
                    {
                        if (SolverButton.ToolTipText == "Disable Solver")
                        { 
                            GH_Document.EnableSolutions = true; 
                        }
                    }
                };
                toolbar.Items.Add(SolverButton);

            }
        }
    }
}

Hello,

At first, you can access the toolbar with Grasshopper.Instances.DocumentEditor.MainMenuStrip.
And your method should be called in Grasshopper.Instances.CanvasCreated event. This is to ensure that all UI objects have been created.

I just saw your previous message. Automatically add buttons to the toolbar when GHA is loaded? - #4 by seghierkhaled
If it’s the same question, my answer is wrong and I don’t know.
The Grasshopper.Instances.DocumentEditor.MainMenuStrip provides access to the top level toolbar:

Hi @kitjmv
Thank you, what i want is a permanent button
At this moment i use python script and need place it every time to add the button to the toolbar.
I see in rhino.inside-bricscaf source code ,they call Grasshopper as command with code of the button.
I don’t know how to call the above script when we click Grasshopper button in Rhino.

Thanks again, i just want permanent button
I don’t need the menu

Sorry I do not understand.
Maybe a image is better…

I assume you are using this model:

Inside a Rhino plugin:

public class Plugin_Rhino : PlugIn
{
     public Plugin_Rhino () {
          RhinoApp.Initialized += OnRhinoAppInitialized;
     }

     void OnRhinoAppInitialized (object sender, EventArgs e) {
          RhinoApp.Initialized -= OnRhinoAppInitialized;
          Grasshopper.Instances.CanvasCreated += CreateGrasshopperUI;
     }

    void CreateGrasshopperUI (GH_Canvas canvas) {
          Grasshopper.Instances.CanvasCreated -= CreateGrasshopperUI;
         ...
    }
}

Exactly
Looks like i need to create a dll with the second code?
CreateGrasshopperUI …

10

I don’t know what you call “second code” but you must have a Rhino plugin (like my example to initialize CanvasCreated event) and the Grasshopper plugin

(CreateGrasshopperUI is the name I chose)

11

Thank you , i will try it

Note that your Rhino plugin can reference your Grasshopper project and your CreateGrasshopperUI method can be placed in the GH plugin:

void OnRhinoAppInitialized (object sender, EventArgs e) {
          RhinoApp.Initialized -= OnRhinoAppInitialized;
          Grasshopper.Instances.CanvasCreated += MyGrasshopperPluginClass.CreateGrasshopperUI;
 }

I don’t understand why we need Rhino plugin (rhp)?
I see many Grasshopper addon have unique buttons loaded automatically.

14

It uses a private grasshopper function LoadGHA:

      var LoadGHAProc = Grasshopper.Instances.ComponentServer.GetType().GetMethod("LoadGHA", BindingFlags.NonPublic | BindingFlags.Instance);

To be honest, if you don’t understand the Grasshopper loading process, use two plugins.

That said, I really don’t understand.
If you have a Grasshopper loaded, just call the function that creates your menu.
in your first post, an explanation of the error would be helpful

16

Calling the function is not the problem.
When i run the code, the button added immediately to the toolbar.
But i want the button appears automatically when Grasshopper opened, which mean -maybe- autorun the function.

17

Finally it works, i find a solution after checking PersistentDataEditor
