Detail
The ColorSelection is a widget that is used to select a color. It
consists of a color wheel and number of sliders and entry boxes for color
parameters such as hue, saturation, value, red, green, blue, and opacity. It
is found on the standard color selection dialog box ColorSelectionDialog.
Class Hierarchy
Types
data ColorSelection Source
Instances
class VBoxClass o => ColorSelectionClass o Source
Instances
castToColorSelection :: GObjectClass obj => obj -> ColorSelection Source
toColorSelection :: ColorSelectionClass o => o -> ColorSelection Source
Constructors
colorSelectionNew :: IO ColorSelection Source
Creates a new ColorSelection.
Methods
colorSelectionGetCurrentAlpha Source
Arguments
| :: ColorSelectionClass self | |
| => self | |
| -> IO Int | returns an integer between 0 and 65535. |
Returns the current alpha value.
colorSelectionSetCurrentAlpha Source
Arguments
| :: ColorSelectionClass self | |
| => self | |
| -> Int |
|
| -> IO () |
Sets the current opacity to be alpha. The first time this is called, it
will also set the original opacity to be alpha too.
colorSelectionGetCurrentColor :: ColorSelectionClass self => self -> IO Color Source
Gets the current color in the ColorSelection widget.
colorSelectionSetCurrentColor Source
Arguments
| :: ColorSelectionClass self | |
| => self | |
| -> Color |
|
| -> IO () |
Sets the current color to be color. The first time this is called, it
will also set the original color to be color too.
colorSelectionGetHasOpacityControl Source
Arguments
| :: ColorSelectionClass self | |
| => self | |
| -> IO Bool | returns |
Determines whether the ColorSelection widget has an opacity control.
colorSelectionSetHasOpacityControl Source
Arguments
| :: ColorSelectionClass self | |
| => self | |
| -> Bool |
|
| -> IO () |
Sets the ColorSelection widget to use or not use opacity.
colorSelectionGetHasPalette Source
Arguments
| :: ColorSelectionClass self | |
| => self | |
| -> IO Bool | returns |
Determines whether the color selector has a color palette.
colorSelectionSetHasPalette Source
Arguments
| :: ColorSelectionClass self | |
| => self | |
| -> Bool |
|
| -> IO () |
Sets whether to show or hide the palette.
colorSelectionGetPreviousAlpha Source
Arguments
| :: ColorSelectionClass self | |
| => self | |
| -> IO Int | returns an integer between 0 and 65535. |
Returns the previous alpha value.
colorSelectionSetPreviousAlpha Source
Arguments
| :: ColorSelectionClass self | |
| => self | |
| -> Int |
|
| -> IO () |
Sets the 'previous' alpha to be alpha. This function should be called
with some hesitations, as it might seem confusing to have that alpha change.
colorSelectionGetPreviousColor :: ColorSelectionClass self => self -> IO Color Source
Returns the original color value.
colorSelectionSetPreviousColor :: ColorSelectionClass self => self -> Color -> IO () Source
Sets the 'previous' color to be color. This function should be called
with some hesitations, as it might seem confusing to have that color change.
Calling colorSelectionSetCurrentColor will also set this color the first
time it is called.
colorSelectionIsAdjusting :: ColorSelectionClass self => self -> IO Bool Source
Gets the current state of the widget. Returns True if the user is currently dragging a color around, and False if the selection has stopped.
Attributes
colorSelectionHasOpacityControl :: ColorSelectionClass self => Attr self Bool Source
Whether the color selector should allow setting opacity.
Default value: False
colorSelectionHasPalette :: ColorSelectionClass self => Attr self Bool Source
Whether a palette should be used.
Default value: False
colorSelectionCurrentAlpha :: ColorSelectionClass self => Attr self Int Source
The current opacity value (0 fully transparent, 65535 fully opaque).
Allowed values: <= 65535
Default value: 65535
colorSelectionPreviousAlpha :: ColorSelectionClass self => Attr self Int Source
'previousAlpha' property. See colorSelectionGetPreviousAlpha and
colorSelectionSetPreviousAlpha
