|
| colorSelectionGetCurrentAlpha :: ColorSelectionClass obj => obj -> IO Int |
Returns the current alpha value.
- The alpha value is represented by an integer between 0 and 65535.
|
|
| colorSelectionSetCurrentAlpha :: ColorSelectionClass obj => obj -> Int -> IO () |
Sets the current opacity. The first time this is called, it will also set
the original opacity too.
- The alpha value is represented by an integer between 0 and 65535.
|
|
| colorSelectionGetCurrentColor :: ColorSelectionClass obj => obj -> IO Color |
| Gets the current color in the ColorSelection widget.
|
|
| colorSelectionSetCurrentColor :: ColorSelectionClass obj => obj -> Color -> IO () |
| Sets the current color. The first time this is called, it will also set the
original color too.
|
|
| colorSelectionGetHasOpacityControl :: ColorSelectionClass obj => obj -> IO Bool |
| Sets the ColorSelection widget to use or not use opacity.
|
|
| colorSelectionSetHasOpacityControl :: ColorSelectionClass obj => obj -> Bool -> IO () |
| Determines whether the ColorSelection widget has an opacity control.
|
|
| colorSelectionGetHasPalette :: ColorSelectionClass obj => obj -> IO Bool |
| Determines whether the color selector has a color palette.
|
|
| colorSelectionSetHasPalette :: ColorSelectionClass obj => obj -> Bool -> IO () |
| Sets whether to show or hide the palette.
|
|
| colorSelectionGetPreviousAlpha :: ColorSelectionClass obj => obj -> IO Int |
| Returns the previous alpha value.
|
|
| colorSelectionSetPreviousAlpha :: ColorSelectionClass obj => obj -> Int -> IO () |
Sets the 'previous' alpha to the given value.
- This function should be called with some hesitations, as it might seem
confusing to have that alpha change.
|
|
| colorSelectionGetPreviousColor :: ColorSelectionClass obj => obj -> IO Color |
| Returns the original color value.
|
|
| colorSelectionSetPreviousColor :: ColorSelectionClass obj => obj -> Color -> IO () |
Sets the 'previous' 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 obj => obj -> IO Bool |
| 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.
