Hello everyone,

I've been trying to implement the toolbox feature for the maxima plugin that I am currently working on. The example that I am following is from Davide Carpi

https://smath.info:8443/!/#public/view/head/plugins/CustomFunctions/Toolbox.cs

When implementing ButtonsMetaData[] part, it shows me an error "ButtonsMetaData.ButtonsMetaData()" is inaccessible due to its protection level. Any idea on what did I do wrong or way to fix this?

Regards,

Muiz

I'm not sure that the Toolbox code in Custom Functions is updated to the latest API changes, since that feature is not activated there;

please check one of the following:

You might find the latter more interesting since implements also the SVG rendering.

If you like my plugins please consider to support the program buying a license; for personal contributions to me: paypal.me/dcprojects

Greetings,

I vaguely remember having a similar issue. I program in VB.NET, so part of my issue was converting code from C# to VB.NET, but I'll rattle off some items:

Make sure you set up your class correctly; ｢Implements｣ IPluginToolboxGroups instead of ｢Inherits｣ or ｢Delegate｣ or ｢Shared｣
Subs/Functions/Variables must use appropriate permissions; I think I had some as ｢Private｣ or ｢Protected｣, but had to use ｢Public｣ ¿Maybe?

I broke up my ButtonsMetaData declarations; instead of having an inline statement like you, I created an object and then modified the properties; I remember having some trouble getting an inline statement to work...


      Dim btnButtonA2 As ButtonsMetaData = New ButtonsMetaData(" Δ°F "
      btnButtonA2.Action = "'Δ°F"
      btnButtonA2.Description = "Degrees Fahrenheit, Difference of"


      Dim toolGrp_A As ToolboxGroup = New ToolboxGroup()
      toolGrp_A.Title = "Engineering Toolbar"
      toolGrp_A.Buttons = {btnButtonA1, btnButtonA2, btnButtonA3}

      Return (New ToolboxGroup() {toolGrp_A})

As a final note (for what its worth): this is the class I am using:

SMath.Manager.ButtonsMetaData

Your problem may be the "ButtonsMetaData.ButtonsMetaData()".

I'm using v0.99 so that may also be an item to note between us.

May this be of Good Help;
