Customizable Color Picker

As a starting point, I used Luis Ortega's code from A Color Picker.

This customizable color picker was designed because I needed a color picker that could calculate itself when passed an array of colors. I didn't want to use a resource file, so the entire color dialog is created dynamically from memory. This makes using the control quick and easy. I have included methods for customizing the border sizes, number of well columns, well heights, and well shapes. The control is designed for loading colors at run-time (from a database,for example). There is not support for serialization, persistance to the registry, or an "other" button. These can be easily added if needed. My project didn't need them, so I didn't bother adding them.

A demo project is included. I hope someone else can get some use out of this code, too. :-)

How to include in your project

  1. Copy ColorBtn.cpp and ColorBtn.h into your project directory.
  2. Add ColorBtn.cpp to your project.

How to use

  1. Create a button on your dialog. Mark it as "Owner Draw".
  2. Declare a variable in your dialog class, like this:
    CColorBtn colorbtn;
  3. At OnInitDialog, call SubclassDlgItem, like this:
    colorbtn.SubclassDlgItem(IDC_BUTTON,this); // Use your button ID here
  4. Add Colors to the button's color dialog using AddColorWell or SetColorsFromArray
  5. Customize the button's color dialog by setting the number of columns, border widths, and shape variables
  6. Repeat the process for each button you want. (See the sample project provided for more details)

You can set and read the selected color using the "m_CurrentColor" member variable.
