- \class ColorDialog ColorDialog.h
- \brief The OColorDialog class provides a dialog widget for specifying colors.
- \ingroup dialogs
-
- The color dialog's function is to allow users to choose colors -
- for instance, you might use this in a drawing program to allow the
- user to set the brush color.
-
- This version of Qt only provides modal color dialogs. The static
- getColor() function shows the dialog and allows the user to specify a color,
- while getRgba() does the same but allows the user to specify a color with an
- alpha channel (transparency) value.
-
- The user can store customCount() different custom colors. The custom
- colors are shared by all color dialogs, and remembered during the
- execution of the program. Use setCustomColor() to set the
- custom colors, and customColor() to get them.
-
