#propertygrid

Besides basic types, PropertyGrid also has a good support with collection classes. In my editor, I created a wrapper class with CLI/C++ to expose C++ material as C# property. A collection of wrapper materials can be accessed in PropertyGrid.

property List<ManagedMaterial^>^ Materials

{     List<ManagedMaterial^>^ get(); }

Within the collection, each element’s properties are shown on the right. As long as the accessors and mutators are properly set, this field should come up automatically.

SeBesides my own engine, I have developed an editor with C# and CLI/C++. PropertyGrid is a good control to set and retrieve object properties.

(Editor with PropertyGrid panel on the right)

To bind an object to PropertyGrid, just set SelectedObject on PropertyGrid to your object:

propertyGrid1.SelectedObject = myGameObject;

To have properties shown up on the grid, object class must have accessor for the property. A mutator is optional when property is read-only to user.

PropertyGrid is very flexible with basic data types and string. For a structural data such as vector3, a good idea is to convert data to string for display/modification, and store to vector3 from string value. Let’s take property position as an example:

property String^ Position {     String^ get()     {         return Vec3ToString(m_SceneObject->GetPosition());     }

    void set(String^ value)     {         m_SceneObject->SetPosition(StringToVec3(value));     } };

Both accessor and mutator are used to make change to the property in PropertyGrid.

Here are the convertor functions between Vector3 and String:

String^ ManagedSceneObject::Vec3ToString(const RVec3& vec) {     return String::Format(L"{0}, {1}, {2}", vec.x, vec.y, vec.z); }

RVec3 ManagedSceneObject::StringToVec3(String^ str) {     String^ delimStr = ",";     array<Char>^ delimiter = delimStr->ToCharArray();     array<String^>^ words = str->Split(delimiter);

    RVec3 vec;     vec.x = (float)Convert::ToDouble(words[0]);     vec.y = (float)Convert::ToDouble(words[1]);     vec.z = (float)Convert::ToDouble(words[2]);

    return vec; }

Setting ReadOnly Property in PropertyGrid Sets All Properties Readonly

I am using a PropertyGrid control to edit my class properties and I am trying to set certain properties read-only depending on other property settings.

This is the code of my class:

Imports System.ComponentModel Imports System.Reflection Public Class PropertyClass Private _someProperty As Boolean = False Public Property SomeProperty As Boolean Get Return _someProperty End Get Set(value As…
