/**
|
||
* GtkSpinButton:
|
||
*
|
||
* A `GtkSpinButton` is an ideal way to allow the user to set the
|
||
* value of some attribute.
|
||
*
|
||
* 
|
||
*
|
||
* Rather than having to directly type a number into a `GtkEntry`,
|
||
* `GtkSpinButton` allows the user to click on one of two arrows
|
||
* to increment or decrement the displayed value. A value can still be
|
||
* typed in, with the bonus that it can be checked to ensure it is in a
|
||
* given range.
|
||
*
|
||
* The main properties of a `GtkSpinButton` are through an adjustment.
|
||
* See the [class@Gtk.Adjustment] documentation for more details about
|
||
* an adjustment's properties.
|
||
*
|
||
* Note that `GtkSpinButton` will by default make its entry large enough
|
||
* to accommodate the lower and upper bounds of the adjustment. If this
|
||
* is not desired, the automatic sizing can be turned off by explicitly
|
||
* setting [property@Gtk.Editable:width-chars] to a value != -1.
|
||
*
|
||
* ## Using a GtkSpinButton to get an integer
|
||
*
|
||
* ```c
|
||
* // Provides a function to retrieve an integer value from a GtkSpinButton
|
||
* // and creates a spin button to model percentage values.
|
||
*
|
||
* int
|
||
* grab_int_value (GtkSpinButton *button,
|
||
* gpointer user_data)
|
||
* {
|
||
* return gtk_spin_button_get_value_as_int (button);
|
||
* }
|
||
*
|
||
* void
|
||
* create_integer_spin_button (void)
|
||
* {
|
||
*
|
||
* GtkWidget *window, *button;
|
||
* GtkAdjustment *adjustment;
|
||
*
|
||
* adjustment = gtk_adjustment_new (50.0, 0.0, 100.0, 1.0, 5.0, 0.0);
|
||
*
|
||
* window = gtk_window_new ();
|
||
*
|
||
* // creates the spinbutton, with no decimal places
|
||
* button = gtk_spin_button_new (adjustment, 1.0, 0);
|
||
* gtk_window_set_child (GTK_WINDOW (window), button);
|
||
*
|
||
* gtk_window_present (GTK_WINDOW (window));
|
||
* }
|
||
* ```
|
||
*
|
||
* ## Using a GtkSpinButton to get a floating point value
|
||
*
|
||
* ```c
|
||
* // Provides a function to retrieve a floating point value from a
|
||
* // GtkSpinButton, and creates a high precision spin button.
|
||
*
|
||
* float
|
||
* grab_float_value (GtkSpinButton *button,
|
||
* gpointer user_data)
|
||
* {
|
||
* return gtk_spin_button_get_value (button);
|
||
* }
|
||
*
|
||
* void
|
||
* create_floating_spin_button (void)
|
||
* {
|
||
* GtkWidget *window, *button;
|
||
* GtkAdjustment *adjustment;
|
||
*
|
||
* adjustment = gtk_adjustment_new (2.500, 0.0, 5.0, 0.001, 0.1, 0.0);
|
||
*
|
||
* window = gtk_window_new ();
|
||
*
|
||
* // creates the spinbutton, with three decimal places
|
||
* button = gtk_spin_button_new (adjustment, 0.001, 3);
|
||
* gtk_window_set_child (GTK_WINDOW (window), button);
|
||
*
|
||
* gtk_window_present (GTK_WINDOW (window));
|
||
* }
|
||
* ```
|
||
*
|
||
* # CSS nodes
|
||
*
|
||
* ```
|
||
* spinbutton.horizontal
|
||
* ├── text
|
||
* │ ├── undershoot.left
|
||
* │ ╰── undershoot.right
|
||
* ├── button.down
|
||
* ╰── button.up
|
||
* ```
|
||
*
|
||
* ```
|
||
* spinbutton.vertical
|
||
* ├── button.up
|
||
* ├── text
|
||
* │ ├── undershoot.left
|
||
* │ ╰── undershoot.right
|
||
* ╰── button.down
|
||
* ```
|
||
*
|
||
* `GtkSpinButton`s main CSS node has the name spinbutton. It creates subnodes
|
||
* for the entry and the two buttons, with these names. The button nodes have
|
||
* the style classes .up and .down. The `GtkText` subnodes (if present) are put
|
||
* below the text node. The orientation of the spin button is reflected in
|
||
* the .vertical or .horizontal style class on the main node.
|
||
*
|
||
* # Accessibility
|
||
*
|
||
* `GtkSpinButton` uses the %GTK_ACCESSIBLE_ROLE_SPIN_BUTTON role.
