Detailed Description
A slider widget for selecting a value from a range.
A Gtk::Scale is a slider control used to select a numeric value. To use it, you'll probably want to investigate the methods on its base class, Gtk::Range , in addition to the methods for Gtk::Scale itself. To set the value of a scale, you would normally use set_value() . To detect changes to the value, you would normally use signal_value_changed() .
Note that using the same upper and lower bounds for the Scale (through the Range methods) will hide the slider itself. This is useful for applications that want to show an undeterminate value on the scale, without changing the layout of the application (such as movie or music players).

Member Function Documentation
void Gtk::Scale::add_mark | ( | double | value , |
PositionType | position , | ||
const Glib::ustring & | markup | ||
) |
Adds a mark at value .
A mark is indicated visually by drawing a tick mark next to the scale, and GTK+ makes it easy for the user to position the scale exactly at the marks value.
If
markup
is not
nullptr
, text is shown next to the tick mark.
To remove marks from a scale, use clear_marks() .
- Parameters
-
value The value at which the mark is placed, must be between the lower and upper limits of the scales’ adjustment. position Where to draw the mark. For a horizontal scale, Gtk::POS_TOP and Gtk::POS_LEFT are drawn above the scale, anything else below. For a vertical scale, Gtk::POS_LEFT and Gtk::POS_TOP are drawn to the left of the scale, anything else to the right. markup Text to be shown at the mark, using [ Pango markup][PangoMarkupFormat], or nullptr
.
|
protected virtual |
void Gtk::Scale::clear_marks | ( | ) |
Removes any marks that have been added with add_mark() .
|
protected virtual |
int Gtk::Scale::get_digits | ( | ) | const |
Get the number of decimal digits.
bool Gtk::Scale::get_draw_value | ( | ) | const |
Get whether the current value is displayed as a string next to the slider.
bool Gtk::Scale::get_has_origin | ( | ) | const |
Glib::RefPtr < Pango::Layout > Gtk::Scale::get_layout | ( | ) |
Gets the Pango::Layout used to display the scale.
The returned object is owned by the scale so does not need to be freed by the caller.
- Returns
-
The
Pango::Layout
for this scale, or
nullptr
if the Gtk::Scale::property_draw_value() property isfalse
.
Glib::RefPtr <const Pango::Layout > Gtk::Scale::get_layout | ( | ) | const |
Gets the Pango::Layout used to display the scale.
The returned object is owned by the scale so does not need to be freed by the caller.
- Returns
-
The
Pango::Layout
for this scale, or
nullptr
if the Gtk::Scale::property_draw_value() property isfalse
.
void Gtk::Scale::get_layout_offsets | ( | int & | x , |
int & | y | ||
) | const |
Obtains the coordinates where the scale will draw the Pango::Layout representing the text in the scale.
Remember when using the Pango::Layout function you need to convert to and from pixels using PANGO_PIXELS() or Pango::SCALE .
If the
Gtk::Scale::property_draw_value()
property is
false
, the return values are undefined.
- Parameters
-
x Location to store X offset of layout, or nullptr
.y Location to store Y offset of layout, or nullptr
.

Glib::PropertyProxy < int > Gtk::Scale::property_digits | ( | ) |
Number of displayed decimal digits.
The number of decimal places that are displayed in the value.
- Returns
- A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.
Glib::PropertyProxy_ReadOnly < int > Gtk::Scale::property_digits | ( | ) | const |
The number of decimal places that are displayed in the value.
- Returns
- A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.
Glib::PropertyProxy < bool > Gtk::Scale::property_draw_value | ( | ) |
Whether to draw the value as a string next to slider.
Whether the current value is displayed as a string next to the slider.
- Returns
- A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.
Glib::PropertyProxy_ReadOnly < bool > Gtk::Scale::property_draw_value | ( | ) | const |
Whether the current value is displayed as a string next to the slider.
- Returns
- A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.
Glib::PropertyProxy < bool > Gtk::Scale::property_has_origin | ( | ) |
Whether the scale has an origin.
- Returns
- A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.
Glib::PropertyProxy_ReadOnly < bool > Gtk::Scale::property_has_origin | ( | ) | const |
Whether the scale has an origin.
- Returns
- A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.
Glib::PropertyProxy < PositionType > Gtk::Scale::property_value_pos | ( | ) |
The position in which the value is displayed.
The position in which the current value is displayed.
- Returns
- A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.
Glib::PropertyProxy_ReadOnly < PositionType > Gtk::Scale::property_value_pos | ( | ) | const |
The position in which the current value is displayed.
- Returns
- A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.
void Gtk::Scale::set_digits | ( | int | digits | ) |
Set the number of decimal digits.
This also causes the adjustment to be rounded off so the retrieved value matches the value the user sees. Setting digits to 1 gives for example 1.0, 2 gives 1.00, etc.
void Gtk::Scale::set_draw_value | ( | bool |
draw_value
=
true
|
) |
Set whether the current value is displayed as a string next to the slider.
void Gtk::Scale::set_has_origin | ( | bool |
has_origin
=
true
|
) |
If
has_origin
is set to
true
(the default), the scale will highlight the part of the scale between the origin (bottom or left side) of the scale and the current value.
- Parameters
-
has_origin true
if the scale has an origin.
void Gtk::Scale::set_value_pos | ( | PositionType | pos | ) |
Set the position in which the value is displayed.
Glib::SignalProxy < Glib::ustring ,double > Gtk::Scale::signal_format_value | ( | ) |
- Slot Prototype:
-
Glib::ustring on_my_format_value(double value)
Signal which allows you to change how the scale value is displayed. Connect a signal handler which returns an allocated string representing value . That string will then be used to display the scale's value.
Here's an example signal handler which displays a value 1.0 as with "-->1.0<--".
[C example ellipted]
- Parameters
-
value The value to format.
- Returns
- Allocated string representing value .
