| adjustmentNew :: Double -> Double -> Double -> Double -> Double -> Double -> IO Adjustment |
Create a new Adjustment object.
- The creation function take every value that is contained in the object:
value is the initial value and should be between the
upper and lower bounds of the slider. Clicking on the
arrows increases this value by stepIncrement. Clicking in the
slider advances by pageIncrement. The pageSize is
needed to determine if the end of the slider is still in the range.
|
|
| adjustmentSetValue :: Adjustment -> Double -> IO () |
| Set the current value of the Adjustment object.
|
|
| adjustmentGetValue :: Adjustment -> IO Double |
| Get the current value of the Adjustment object.
|
|
| adjustmentClampPage :: Adjustment -> Double -> Double -> IO () |
Ensure that the alignment is within these
bounds.
- Updates the Adjustment value to ensure that the range between lower and
upper is in the current page (i.e. between value and value + page_size).
If the range is larger than the page size, then only the start of it will
be in the current page. A "changed" signal will be emitted if the value
is changed.
|
|
| onAdjChanged :: Adjustment -> IO () -> IO (ConnectId Adjustment) |
| This signal is emitted if some value of
Adjustment except value itself changes.
|
|
| afterAdjChanged :: Adjustment -> IO () -> IO (ConnectId Adjustment) |
|
| onValueChanged :: Adjustment -> IO () -> IO (ConnectId Adjustment) |
| This signal is emitted if the value of the
Alignment object changed.
|
|
| afterValueChanged :: Adjustment -> IO () -> IO (ConnectId Adjustment) |
