Detailed Description
A color wheel widget.
This widget allows the user to choose the hue (as defined in the LCH color space).
- Note
- This widget always accepts focus by a mouse click within the circle. This happens regardless of the
QWidget::focusPolicy
property:- If you set the
QWidget::focusPolicy
property to a value that does not accept focus by mouse click, the focus will nevertheless be accepted for clicks within the actual circle. (This is the default behavior.) - If you set the
QWidget::focusPolicy
property to a value that accepts focus by mouse click, the focus will not only be accepted for clicks within the actual circle, but also for clicks anywhere within the (rectangular) widget.
- If you set the
Definition at line 64 of file colorwheel.h.
Property Documentation
◆ hue
|
readwrite |
The currently selected hue.
This is the hue angle, as defined in the LCH color model.
Measured in degree.
Valid range: [0°, 360°[. The widget accepts initially also out-of-range values, but once a user interaction has taken place, it will hold a normalized value. So
- 0 gets 0
- 359.9 gets 359.9
- 360 gets 0
- 361.2 gets 1.2
- 720 gets 0
- -1 gets 359
- -1.3 gets 358.7
- See also
- READ hue() const
- WRITE setHue()
- NOTIFY hueChanged()

Constructor & Destructor Documentation
◆ ColorWheel()
|
explicit |
Constructor.
- Parameters
-
colorSpace The color space within which this widget should operate. Can be created with RgbColorSpaceFactory. parent The widget’s parent widget. This parameter will be passed to the base class’s constructor.
Definition at line 38 of file colorwheel.cpp.
◆ ~ColorWheel()

Member Function Documentation
◆ hue()
|
nodiscard |
◆ hueChanged
|
signal |
◆ keyPressEvent()
|
overrideprotectedvirtual |
React on key press events.
Reimplemented from base class.
Reacts on key press events. When the plus key or the minus key are pressed, it raises or lowers the hue. When Qt::Key_Insert
or Qt::Key_Delete
are pressed, it raises or lowers the hue faster.
- Parameters
-
event the corresponding event
Reimplemented from QWidget.
Definition at line 257 of file colorwheel.cpp.
◆ minimumSizeHint()
|
nodiscardoverridevirtual |
Recommended minimum size for the widget.
Reimplemented from base class.
- Returns
- Recommended minimum size for the widget.
- See also
- sizeHint()
Reimplemented from QWidget.
Definition at line 452 of file colorwheel.cpp.
◆ mouseMoveEvent()
|
overrideprotectedvirtual |
React on a mouse move event.
Reimplemented from base class.
Reacts only on mouse move events if previously there had been a mouse press event that had been accepted. If previously there had not been a mouse press event, the mouse move event is ignored.
- Parameters
-
event The corresponding mouse event
Reimplemented from QWidget.
Definition at line 175 of file colorwheel.cpp.
◆ mousePressEvent()
|
overrideprotectedvirtual |
React on a mouse press event.
Reimplemented from base class.
Does not differentiate between left, middle and right mouse click.
If the mouse is clicked within the wheel ribbon, than the handle is placed here and further mouse movements are tracked.
- Parameters
-
event The corresponding mouse event
Reimplemented from QWidget.
Definition at line 133 of file colorwheel.cpp.
◆ mouseReleaseEvent()
|
overrideprotectedvirtual |
React on a mouse release event.
Reimplemented from base class. Does not differentiate between left, middle and right mouse click.
- Parameters
-
event The corresponding mouse event
Reimplemented from QWidget.
Definition at line 198 of file colorwheel.cpp.
◆ paintEvent()
|
overrideprotectedvirtual |
Paint the widget.
Reimplemented from base class.
- Parameters
-
event the paint event
Reimplemented from QWidget.
Definition at line 304 of file colorwheel.cpp.
◆ resizeEvent()
|
overrideprotectedvirtual |
React on a resize event.
Reimplemented from base class.
- Parameters
-
event The corresponding resize event
Reimplemented from QWidget.
Definition at line 393 of file colorwheel.cpp.
◆ setHue
|
slot |
Setter for the hue property.
- Parameters
-
newHue the new hue
Definition at line 414 of file colorwheel.cpp.
◆ sizeHint()
|
nodiscardoverridevirtual |
Recommended size for the widget.
Reimplemented from base class.
- Returns
- Recommended size for the widget.
- See also
- minimumSizeHint()
Reimplemented from QWidget.
Definition at line 440 of file colorwheel.cpp.
◆ wheelEvent()
|
overrideprotectedvirtual |
React on a mouse wheel event.
Reimplemented from base class.
Scrolling up raises the hue value, scrolling down lowers the hue value. Of course, the point at 0°/360° it not blocking.
- Parameters
-
event The corresponding mouse event
