Detailed Description

Class for visual selection of a color from the color grid.

An example of ColorGrid

ColorGrid can use a custom (user-defined) color scheme, as well as one of pre-defined ones (see setScheme() function). Also, the size of color cells and their layout can be customized.

A color can be picked from the grid with the mouse or with the cursor and Enter keys (see setPickByDrag() and setClickMode() functions).

Signal picked() is emitted when the user picks a color from the grid. Signal highlighted() is emitted when the user moves mouse cursor over the grid.

Member Enumeration Documentation

enum QSint::ColorGrid::ClickMode

Defines color selection behavior.

Enumerator
CM_PRESS	a color is picked when mouse button has been pressed
CM_RELEASE	a color is picked when mouse button has been released

Constructor & Destructor Documentation

QSint::ColorGrid::ColorGrid ( QWidget * parent = 0 )

Constructor.

QSint::ColorGrid::~ColorGrid ( )

virtual

Destructor.

Member Function Documentation

bool QSint::ColorGrid::autoSize ( ) const

inline

Returns true if autosize has been enabled.

See Also: setAutoSize()

ColorList * QSint::ColorGrid::baseColors ( )

static

Returns default color scheme based on 16 base colors.

See Also: setScheme()

int QSint::ColorGrid::cellSize ( ) const

inline

Returns size of a color cell in pixels.

ClickMode QSint::ColorGrid::clickMode ( ) const

inline

Returns currently active color picking mode.

See Also: setClickMode()

ColorList * QSint::ColorGrid::defaultColors ( )

static

Returns default color scheme.

See Also: setScheme()

ColorList * QSint::ColorGrid::defaultColors2 ( )

static

Returns second default color scheme.

See Also: setScheme()

int QSint::ColorGrid::heightInCells ( ) const

Returns height of the grid in cells.

void QSint::ColorGrid::highlighted ( const QColor & color )

signal

Emitted when user moves mouse cursor over the grid or changes selection with the cursor keys.

color is the color value under the cursor.

const QColor& QSint::ColorGrid::lastHighlighted ( ) const

inline

Returns a recently highlighted color.

See Also: highlighted()

const QColor& QSint::ColorGrid::lastPicked ( ) const

inline

Returns a recently picked color.

See Also: picked()

ColorList * QSint::ColorGrid::namedColors ( )

static

Returns default color scheme based on QColor::colorNames() list.

See Also: setScheme()

bool QSint::ColorGrid::pickByDrag ( ) const

inline

Returns true if pick-by-drag mode has been enabled.

See Also: setPickByDrag()

void QSint::ColorGrid::picked ( const QColor & color )

signal

Emitted when user picks a color from the grid.

color is the picked color value.

ColorList* QSint::ColorGrid::scheme ( ) const

inline

Returns currently active color scheme (by default, defaultColors() is used).

See Also: setScheme()

void QSint::ColorGrid::setAutoSize ( bool autosize )

Sets autosize mode to autosize (disabled by default).

If autosize mode is enabled, the size of the grid is calculated automatically based on number of colors in the current color scheme. In this mode, calls to setWidthInCells() are ignored.

void QSint::ColorGrid::setCellSize ( int size )

Sets size of a color cell in pixels to size (must be > 0).

void QSint::ColorGrid::setClickMode ( ClickMode mode )

inline

Sets color picking mode to mode.

void QSint::ColorGrid::setPickByDrag ( bool set )

inline

Sets pick-by-drag mode to set (disabled by default).

If pick-by-drag mode is enabled, then signal picked() is emitted when the user drags mouse over the grid with pressed mouse button.

void QSint::ColorGrid::setScheme ( ColorList * scheme )

Sets color scheme to scheme.

void QSint::ColorGrid::setWidthInCells ( int width )

Sets width of the grid in cells to width (must be > 0).

int QSint::ColorGrid::widthInCells ( ) const

inline

Returns width of the grid in cells.
