Create a Popup Dialog with colors on it

Rhino Developer

I have a color mapping dictionary, whose keys and values are:

  • Key: a number
  • Value: A color mapped to that key

Can I create a dialog (or a popup), that shown the color alongside it’s associated value ? Something along the line of the figure below.

Cheers!

Hi,
I’m not sure about a custom dialog, It does sound possible.
One way I’d tackle this problem is by using a form instead.
You can use the System.Windows.Forms.Panel class and the System.Drawing.Color class. Here is an example of how you might do this:

import System.Drawing
import System.Windows.Forms

# Create a dictionary that maps colors to their values
color_values = {
    System.Drawing.Color.Red: 100,
    System.Drawing.Color.Green: 200,
    System.Drawing.Color.Blue: 300
}

# Create a panel
panel = System.Windows.Forms.Panel()

# Set the panel's layout to a vertical flow layout

panel.AutoScroll = True

# Iterate over the colors in the dictionary
for color, value in color_values.items():
    # Create a label for the color
    color_label = System.Windows.Forms.Label()
    color_label.BackColor = color
    color_label.Text = color.Name
    color_label.Width = 100
    color_label.Height = 50

    # Create a label for the value
    value_label = System.Windows.Forms.Label()
    value_label.Text = str(value)
    value_label.Width = 100
    value_label.Height = 50

    # Create a panel for the color and value labels
    color_value_panel = System.Windows.Forms.Panel()
    color_value_panel.Controls.Add(color_label)
    color_value_panel.Controls.Add(value_label)

    # Add the color-value panel to the main panel
    panel.Controls.Add(color_value_panel)

# Display the panel
form = System.Windows.Forms.Form()
form.Controls.Add(panel)
form.Show()
Print "Your nice custom form :)"

Hope that helps

Appreciated, I’m not familiar with the API so your suggestion gave me some pointer.
Currently, I’m using Eto.Drawing.Forms (cause its for C#).
For some reason, the label background color doesn’t show.

Hello,

Here is my current code.

Dictionary<double, Color> colorDict = new Dictionary<double, Color>();

# def create_key,value_pairs_for_colorDict()

Panel panel = new Panel();
DynamicLayout panelLayout = new DynamicLayout();
panelLayout.BeginHorizontal();
foreach (var item in colorDict)
{
    var sysColor = item.Value;
    var etoColor = convertSysToEtoColor(sysColor); 

    Label valueLabel = new Label();
    valueLabel.Text = item.Key.ToString();
    valueLabel.Width = 100;
    valueLabel.Height = 50;

    Label colorLabel = new Label();
    colorLabel.BackgroundColor = etoColor;
    colorLabel.Width = 100;
    colorLabel.Height = 50;

    panelLayout.Add(colorLabel);
    panelLayout.Add(valueLabel);
}
panelLayout.EndHorizontal();
panel.Content = panelLayout;
Form form = new Form();
form.Content = panel;
form.Show();

#conversion between System.Drawing.Color to Eto.Drawing.Color
        private Eto.Drawing.Color convertSysToEtoColor(System.Drawing.Color color)
        {
            Eto.Drawing.Color result = new Eto.Drawing.Color();
            result.A = color.A;
            result.R = color.R;
            result.G = color.G;
            result.B = color.B;
            return result;
        }

Nvm, I found the solution, for some reason, Label.backgroundColor() only works when the Color object is initialized using Color.FromArgb().

            Panel panel = new Panel();
            DynamicLayout panelLayout = new DynamicLayout();
            panelLayout.BeginHorizontal();
            foreach (var item in colorDict)
            {
                var sysColor = item.Value;
                //var etoColor = convertSysToEtoColor(sysColor);

                Label valueLabel = new Label();
                valueLabel.Text = item.Key.ToString();
                valueLabel.Width = 100;
                valueLabel.Height = 50;

                Label colorLabel = new Label();
                colorLabel.BackgroundColor = Color.FromArgb(sysColor.R,
                    sysColor.G, sysColor.B, sysColor.A);
                //colorLabel.BackgroundColor = Colors.LightGreen;

                colorLabel.Width = 100;
                colorLabel.Height = 50;

                panelLayout.Add(colorLabel);
                panelLayout.Add(valueLabel);
            }
            panelLayout.EndHorizontal();
            panel.Content = panelLayout;
            Form form = new Form();
            form.Content = panel;
            form.Show();
