Description |
Create buttons which retain their state
|
|
Synopsis |
|
|
|
|
Detail
|
|
A ToggleButton is a Button which will remain 'pressed-in' when
clicked. Clicking again will cause the toggle button to return to its normal
state.
A toggle button is created by calling either toggleButtonNew or
toggleButtonNewWithLabel. If using the former, it is advisable to pack a
widget, (such as a Label and/or a Pixmap), into the toggle button's
container. (See Button for more information).
The state of a ToggleButton can be set specifically using
toggleButtonSetActive, and retrieved using toggleButtonGetActive.
To simply switch the state of a toggle button, use toggleButtonToggled.

Constructors
|
|
toggleButtonNew :: IO ToggleButton |
Creates a new toggle button. A widget should be packed into the button,
as in buttonNew.
|
|
toggleButtonNewWithLabel |
:: String | label - a string containing the message to be
placed in the toggle button.
| -> IO ToggleButton | | Creates a new toggle button with a text label.
|
|
|
toggleButtonNewWithMnemonic |
:: String | label - the text of the button, with an underscore
in front of the mnemonic character
| -> IO ToggleButton | | Creates a new ToggleButton containing a label. The label will be
created using labelNewWithMnemonic,
so underscores in label indicate the
mnemonic for the button.
|
|
|
Methods
|
|
toggleButtonSetMode |
:: ToggleButtonClass self | | => self | | -> Bool | drawIndicator - if True, draw the button as a separate
indicator and label; if False, draw the button like a normal
button
| -> IO () | | Sets whether the button is displayed as a separate indicator and label.
You can call this function on a CheckButton or a RadioButton with False
to make the button look like a normal button.
This function only affects instances of classes like CheckButton and
RadioButton that derive from ToggleButton, not instances of
ToggleButton itself.
|
|
|
toggleButtonGetMode |
:: ToggleButtonClass self | | => self | | -> IO Bool | returns True if the togglebutton is drawn as a separate
indicator and label.
| Retrieves whether the button is displayed as a separate indicator and
label. See toggleButtonSetMode.
|
|
|
toggleButtonToggled :: ToggleButtonClass self => self -> IO () |
Emits the toggled signal on the ToggleButton. There is no good reason
for an application ever to call this function.
|
|
toggleButtonGetActive :: ToggleButtonClass self => self -> IO Bool |
Queries a ToggleButton and returns its current state. Returns True if
the toggle button is pressed in and False if it is raised.
|
|
toggleButtonSetActive |
:: ToggleButtonClass self | | => self | | -> Bool | isActive - True or False.
| -> IO () | | Sets the status of the toggle button. Set to True if you want the
ToggleButton to be 'pressed in', and False to raise it. This action
causes the toggled signal to be emitted.
|
|
|
toggleButtonGetInconsistent |
|
|
toggleButtonSetInconsistent |
:: ToggleButtonClass self | | => self | | -> Bool | setting - True if state is inconsistent
| -> IO () | | If the user has selected a range of elements (such as some text or
spreadsheet cells) that are affected by a toggle button, and the current
values in that range are inconsistent, you may want to display the toggle in
an "in between" state. This function turns on "in between" display.
Normally you would turn off the inconsistent state again if the user toggles
the toggle button. This has to be done manually,
toggleButtonSetInconsistent only affects visual appearance, it doesn't
affect the semantics of the button.

Attributes
|
|
toggleButtonActive :: ToggleButtonClass self => Attr self Bool |
If the toggle button should be pressed in or not.
Default value: False
|
|
toggleButtonInconsistent :: ToggleButtonClass self => Attr self Bool |
If the toggle button is in an "in between" state.
Default value: False
|
|
toggleButtonDrawIndicator :: ToggleButtonClass self => Attr self Bool |
If the toggle part of the button is displayed.
Default value: False
|
|
toggleButtonMode :: ToggleButtonClass self => Attr self Bool |
'mode' property. See toggleButtonGetMode and toggleButtonSetMode
|
|
Signals
|
|
onToggled :: ToggleButtonClass self => self -> IO () -> IO (ConnectId self) |
Whenever the state of the button is changed, the toggled signal is
emitted.
|
|
afterToggled :: ToggleButtonClass self => self -> IO () -> IO (ConnectId self) |
