Required Methods
fn adjustment(&self) -> Adjustment
fn adjustment(&self) -> Adjustment
Gets the Adjustment
associated with the ScaleButton
’s scale.
See RangeExt::adjustment()
for details.
Returns
the adjustment associated with the scale
Retrieves the minus button of the ScaleButton
.
Returns
the minus button of the ScaleButton
as a Button
Retrieves the plus button of the ScaleButton
.
Returns
the plus button of the ScaleButton
as a Button
fn set_adjustment(&self, adjustment: &impl IsA<Adjustment>)
fn set_adjustment(&self, adjustment: &impl IsA<Adjustment>)
Sets the Adjustment
to be used as a model
for the ScaleButton
’s scale.
See RangeExt::set_adjustment()
for details.
adjustment
Sets the current value of the scale; if the value is outside
the minimum or maximum range values, it will be clamped to fit
inside them. The scale button emits the signal::ScaleButton::value-changed
signal if the value changes.
value
new value of the scale button
The names of the icons to be used by the scale button. The first item in the array will be used in the button when the current value is the lowest value, the second item for the highest value. All the subsequent icons will be used for all the other values, spread evenly over the range of values.
If there’s only one icon name in the icons
array, it will
be used for all the values. If only two icon names are in
the icons
array, the first one will be used for the bottom
50% of the scale, and the second one for the top 50%.
It is recommended to use at least 3 icons so that the
ScaleButton
reflects the current value of the scale
better for the users.
fn connect_popdown<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
fn connect_popdown<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
The ::popdown signal is a [keybinding signal][GtkBindingSignal] which gets emitted to popdown the scale widget.
The default binding for this signal is Escape.
fn emit_popdown(&self)
fn connect_popup<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
fn connect_popup<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
The ::popup signal is a [keybinding signal][GtkBindingSignal] which gets emitted to popup the scale widget.
The default bindings for this signal are Space, Enter and Return.
