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	`alpha` - an integer between 0 and 65535.
-> 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	`color` - A `Color` to set the current color with.
-> 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 `True` if the color selector has an opacity control. `False` if it does't.

Determines whether the ColorSelection widget has an opacity control.

colorSelectionSetHasOpacityControl Source

Arguments

:: ColorSelectionClass self
=> self
-> Bool	`hasOpacity` - `True` if color selector can set the opacity, `False` otherwise.
-> IO ()

Sets the ColorSelection widget to use or not use opacity.

colorSelectionGetHasPalette Source

Arguments

:: ColorSelectionClass self
=> self
-> IO Bool	returns `True` if the selector has a palette. `False` if it hasn't.

Determines whether the color selector has a color palette.

colorSelectionSetHasPalette Source

Arguments

:: ColorSelectionClass self
=> self
-> Bool	`hasPalette` - `True` if palette is to be visible, `False` otherwise.
-> 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	`alpha` - an integer between 0 and 65535.
-> 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
