Detailed Description

The QColorDialog class provides a dialog widget for specifying colors.

The color dialog's function is to allow users to choose colors. For example, you might use this in a drawing program to allow the user to set the brush color.

The static functions provide modal color dialogs.

Warning
This function is not part of the public interface. If you require a modeless dialog, use the QColorDialog constructor.

The static getColor() function shows the dialog, and allows the user to specify a color. This function can also be used to let users choose a color with a level of transparency: pass the ShowAlphaChannel option as an additional argument.

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 use customColor() to get them.

The Standard Dialogs example shows how to use QColorDialog as well as other built-in Qt dialogs.

Enumerations

◆ ColorDialogOption

This enum specifies various options that affect the look and feel of a color dialog.

Since
4.5
  • ShowAlphaChannel Allow the user to select the alpha component of a color.
  • NoButtons Don't display OK and Cancel buttons. (Useful for "live dialogs".)
  • DontUseNativeDialog Use Qt's standard color dialog on the Mac instead of the operating system native color dialog.

◆ getColor() [1/2]

Pops up a modal color dialog with the given window title (or "Select Color" if none is specified), lets the user choose a color, and returns that color.

Since
4.5

The color is initially set to initial. The dialog is a child of parent. It returns an invalid (see QColor::isValid()) color if the user cancels the dialog.

The options argument allows you to customize the dialog.

On Symbian, this static function will use the native color dialog and not a QColorDialog. On Symbian the parameters title and parent has no relevance and the options parameter is only used to define if the native color dialog is used or not.

◆ getRgba()

QRgb QColorDialog::getRgba ( QRgb  initial = 0xffffffff,

Pops up a modal color dialog to allow the user to choose a color and an alpha channel (transparency) value. The color+alpha is initially set to initial. The dialog is a child of parent.

If ok is non-null, *ok is set to true if the user clicked OK, and to false if the user clicked Cancel.

If the user clicks Cancel, the initial value is returned.

Use QColorDialog::getColor() instead, passing the QColorDialog::ShowAlphaChannel option.

◆ open()

QColorDialog::open ( QObject receiver,
const char *  member 
)

Opens the dialog and connects its colorSelected() signal to the slot specified by receiver and member.

Shows the dialog as a window modal dialog, returning immediately.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Since
4.5

The signal will be disconnected from the slot when the dialog is closed.
