How to create a custom panel?

sbcad

Hi,

I would like to create a custom panel, i.e. a little window that can be docked to the left or right side and show a treeview list of items, like the structure panel. I'll be finde to fill the panel, however I need to the starting point. For example, what is the container object to put the control into? If anyone has a little example for this, I would be very grateful!

Thanks

I will be using the .Net Api, developing in C#/Visual Studio. Sorry, I forgot to mention that.

Hi,

You can use a PaletteSet with a UserControl (palette tab) containing your TreeView.

Here's a simple example, The CustomPaletteSet class inherits from PaletteSet.
It contains an instance of TreeViewTab class, the custom class derived from UserControl which contains your TreeView control.

using System;

using Bricscad.Windows;

namespace BricscadPaletteSample
{
    /// <summary>
    /// Describes a custom palette set
    /// </summary>
    public class CustomPaletteSet : PaletteSet
    {
        /// <summary>
        /// Creates a new instance of CustomPalette 
        /// SHOW_PALETTE is the name of the command used to set the palette visible
        /// </summary>
        public CustomPaletteSet() : base("SHOW_PALETTE", new Guid("{0CF42D05-06C0-4D77-9648-04E293538098}"))
        {
            Name = "Palette";
            Style = PaletteSetStyles.ShowAutoHideButton |
                    PaletteSetStyles.ShowCloseButton |
                    PaletteSetStyles.ShowPropertiesMenu;
            MinimumSize = new System.Drawing.Size(250, 150);
            Dock = DockSides.Left;

            // add a palette tab (derived from System.Windows.Forms.UserControl) to the palette set
            Add("Tree View", new TreeViewTab());
        }
    }
}

The Commands class where the command to set the palette visible is defined

using Bricscad.Windows;

using Teigha.Runtime;

namespace BricscadPaletteSample
{
    public class Commands
    {
        static PaletteSet palette;

        [CommandMethod("SHOW_PALETTE")]
        public static void ShowPalette()
        {
            if (palette == null)
                palette = new CustomPaletteSet();
            palette.Visible = true;
        }
    }
}
