Detailed Description

A color selection dialog.


  • Color selection from a wide range of palettes.
  • Color selection from a palette of H vs S and V selectors.
  • Direct input of HSV or RGB values.
  • Saving of custom colors

In most cases, you will want to use the static method KColorDialog::getColor(). This pops up the dialog (with an initial selection provided by you), lets the user choose a color, and returns.


QColor myColor;
int result = KColorDialog::getColor( myColor );

To react to the color selection as it is being selected, the colorSelected() signal can be used. This can be used still in a modal way, for example:

KColorDialog dialog(this);
connect(&dialog, SIGNAL(colorSelected(const QColor &)), this, SLOT(temporarilyChangeColor(const QColor &)));
QColor myColor;
int result = dialog.exec();
changeColor( dialog.color() );
temporarilyChangeColor(myColor); //change back to original color
KDE Color Dialog

The color dialog is really a collection of several widgets which can you can also use separately: the quadratic plane in the top left of the dialog is a KXYSelector. Right next to it is a KHSSelector for choosing hue/saturation.

On the right side of the dialog you see a KColorTable showing a number of colors with a combo box which offers several predefined palettes or a palette configured by the user. The small field showing the currently selected color is a KColorPatch.

Constructor & Destructor Documentation

◆ KColorDialog()

KColorDialog::KColorDialog ( QWidget parent = nullptr,
bool  modal = false 

Constructs a color selection dialog.

Definition at line 994 of file kcolordialog.cpp.

◆ ~KColorDialog()

KColorDialog::~KColorDialog ( )

Destroys the color selection dialog.

Definition at line 1293 of file kcolordialog.cpp.

Member Function Documentation

◆ color()

QColor KColorDialog::color ( ) const

Returns the currently selected color.

◆ colorSelected

void KColorDialog::colorSelected ( const QColor col)

Emitted when a color is selected.

Connect to this to monitor the color as it as selected if you are not running modal.

◆ defaultColor()

QColor KColorDialog::defaultColor ( ) const
the value passed to setDefaultColor

◆ getColor() [1/2]

int KColorDialog::getColor ( QColor theColor,
const QColor defaultColor,
QWidget parent = nullptr 

Creates a modal color dialog, lets the user choose a color, and returns when the dialog is closed.

The selected color is returned in the argument theColor.

This version takes a defaultColor argument, which sets the color selected by the "default color" checkbox. When this checkbox is checked, the invalid color (QColor()) is returned into theColor.

theColorif valid, specifies the color to be initially selected. On return, holds the selected color.
defaultColorcolor selected by the "default color" checkbox

Definition at line 1485 of file kcolordialog.cpp.

◆ getColor() [2/2]

int KColorDialog::getColor ( QColor theColor,
QWidget parent = nullptr 

Creates a modal color dialog, let the user choose a color, and returns when the dialog is closed.

The selected color is returned in the argument theColor.

theColorif valid, specifies the color to be initially selected. On return, holds the selected color.

Definition at line 1466 of file kcolordialog.cpp.

◆ grabColor()

QColor KColorDialog::grabColor ( const QPoint p)

Gets the color from the pixel at point p on the screen.

Definition at line 1750 of file kcolordialog.cpp.

◆ isAlphaChannelEnabled()

bool KColorDialog::isAlphaChannelEnabled ( ) const

Returns true when the user can change the alpha channel.


◆ setAlphaChannelEnabled()

void KColorDialog::setAlphaChannelEnabled ( bool  alpha)

When set to true, the user is allowed to change the alpha component of the color.

The default value is false.


Definition at line 1350 of file kcolordialog.cpp.

◆ setColor

void KColorDialog::setColor ( const QColor col)

Preselects a color.

Definition at line 1458 of file kcolordialog.cpp.

◆ setDefaultColor()

void KColorDialog::setDefaultColor ( const QColor defaultCol)

Call this to make the dialog show a "Default Color" checkbox.

If this checkbox is selected, the dialog will return an "invalid" color (QColor()). This can be used to mean "the default text color", for instance, the one with the KDE text color on screen, but black when printing.
