Expand description
Required Methods
Changes the properties of an existing spin button. The adjustment, climb rate, and number of decimal places are updated accordingly.
adjustment
a Adjustment
to replace the spin button’s
existing adjustment, or None
to leave its current adjustment unchanged
climb_rate
the new climb rate
digits
the number of decimal places to display in the spin button
fn adjustment(&self) -> Adjustment
fn adjustment(&self) -> Adjustment
fn is_numeric(&self) -> bool
fn is_numeric(&self) -> bool
Returns whether non-numeric text can be typed into the spin button.
See set_numeric()
.
Returns
true
if only numeric text can be entered
fn snaps_to_ticks(&self) -> bool
fn snaps_to_ticks(&self) -> bool
Returns whether the values are corrected to the nearest step.
See set_snap_to_ticks()
.
Returns
true
if values are snapped to the nearest step
fn update_policy(&self) -> SpinButtonUpdatePolicy
fn update_policy(&self) -> SpinButtonUpdatePolicy
Gets the update behavior of a spin button.
See set_update_policy()
.
Returns
the current update policy
fn value_as_int(&self) -> i32
fn value_as_int(&self) -> i32
Returns whether the spin button’s value wraps around to the
opposite limit when the upper or lower limit of the range is
exceeded. See set_wrap()
.
Returns
true
if the spin button wraps around
fn set_adjustment(&self, adjustment: &impl IsA<Adjustment>)
fn set_adjustment(&self, adjustment: &impl IsA<Adjustment>)
Replaces the Adjustment
associated with self
.
adjustment
a Adjustment
to replace the existing adjustment
fn set_digits(&self, digits: u32)
fn set_digits(&self, digits: u32)
Set the precision to be displayed by self
. Up to 20 digit precision
is allowed.
digits
the number of digits after the decimal point to be displayed for the spin button’s value
fn set_increments(&self, step: f64, page: f64)
fn set_increments(&self, step: f64, page: f64)
fn set_numeric(&self, numeric: bool)
fn set_numeric(&self, numeric: bool)
Sets the flag that determines if non-numeric text can be typed into the spin button.
numeric
flag indicating if only numeric entry is allowed
fn set_snap_to_ticks(&self, snap_to_ticks: bool)
fn set_snap_to_ticks(&self, snap_to_ticks: bool)
Sets the policy as to whether values are corrected to the nearest step increment when a spin button is activated after providing an invalid value.
snap_to_ticks
a flag indicating if invalid values should be corrected
fn set_update_policy(&self, policy: SpinButtonUpdatePolicy)
fn set_update_policy(&self, policy: SpinButtonUpdatePolicy)
Sets the update behavior of a spin button. This determines whether the spin button is always updated or only when a valid value is set.
policy
a SpinButtonUpdatePolicy
value
Sets the flag that determines if a spin button value wraps around to the opposite limit when the upper or lower limit of the range is exceeded.
wrap
a flag indicating if wrapping behavior is performed
