Sets the acceleration rate for repeated changes when you hold down a button or key.
climb_rate | The rate of acceleration, must be >= 0. |
void Gtk::SpinButton::set_digits | ( | guint | digits | ) |
Set the precision to be displayed by spin_button.
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. |
Sets the step and page increments for spin_button.
This affects how quickly the value changes when the spin button’s arrows are activated.
step | Increment applied for a button 1 press. |
page | Increment applied for a button 2 press. |
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. |
Sets the minimum and maximum allowable values for spin_button.
If the current value is outside this range, it will be adjusted to fit within the range, otherwise it will remain unchanged.
min | Minimum allowable value. |
max | Maximum allowable value. |
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. |
void Gtk::SpinButton::set_update_policy | ( | UpdatePolicy | policy | ) |
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 Gtk::SpinButton::UpdatePolicy value. |
Sets the value of spin_button.
value | The new 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. |
Glib::SignalProxy< void()> Gtk::SpinButton::signal_activate | ( | ) |
void on_my_activate()
Flags: Run Last, Action
Emitted when the spin button is activated.
The keybindings for this signal are all forms of the Enter
key.
If the Enter
key results in the value being committed to the spin button, then activation does not occur until Enter
is pressed again.
Glib::SignalProxy< int(double &)> Gtk::SpinButton::signal_input | ( | ) |
int on_my_input(double& new_value)
Flags: Run Last
Emitted to convert the users input into a double value.
The signal handler is expected to use Gtk::Editable::get_text() to retrieve the text of the spinbutton and set new_value to the new value.
The default conversion uses Glib::strtod().
new_value | Return location for the new value. |
true
for a successful conversion, false
if the input was not handled, and GTK_INPUT_ERROR if the conversion failed. Glib::SignalProxy< bool()> Gtk::SpinButton::signal_output | ( | ) |
bool on_my_output()
Flags: Run Last
Emitted to tweak the formatting of the value for display.
[C example ellipted]
true
if the value has been displayed. Glib::SignalProxy< void()> Gtk::SpinButton::signal_value_changed | ( | ) |
void on_my_value_changed()
Flags: Run Last
Emitted when the value is changed.
Also see the signal_output() signal.
Glib::SignalProxy< void()> Gtk::SpinButton::signal_wrapped | ( | ) |
void on_my_wrapped()
Flags: Run Last
Emitted right after the spinbutton wraps from its maximum to its minimum value or vice-versa.
Increment or decrement a spin button’s value in a specified direction by a specified amount.
direction | A Gtk::SpinType indicating the direction to spin. |
increment | Step increment to apply in the specified direction. |
void Gtk::SpinButton::unset_adjustment | ( | ) |
void Gtk::SpinButton::update | ( | ) |
Manually force an update of the spin button.

A Glib::wrap() method for this object.
object | The C instance. |
take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
