| void Gtk::Range::set_adjustment | ( | const Glib::RefPtr< Adjustment >& | adjustment | ) |
Sets the adjustment to be used as the “model” object for this range widget.
The adjustment indicates the current range value, the minimum and maximum range values, the step/page increments used for keybindings and scrolling, and the page size. The page size is normally 0 for Gtk::Scale and nonzero for Gtk::Scrollbar, and indicates the size of the visible area of the widget being scrolled. The page size affects the size of the scrollbar slider.
- Parameters
-
adjustment A Gtk::Adjustment.
| void Gtk::Range::set_fill_level | ( | double | fill_level | ) |
Set the new position of the fill level indicator.
The “fill level” is probably best described by its most prominent use case, which is an indicator for the amount of pre-buffering in a streaming media player. In that use case, the value of the range would indicate the current play position, and the fill level would be the position up to which the file/stream has been downloaded.
This amount of prebuffering can be displayed on the range’s trough and is themeable separately from the trough. To enable fill level display, use set_show_fill_level(). The range defaults to not showing the fill level.
Additionally, it’s possible to restrict the range’s slider position to values which are smaller than the fill level. This is controller by set_restrict_to_fill_level() and is by default enabled.
- Parameters
-
fill_level The new position of the fill level indicator.
| void Gtk::Range::set_flippable | ( | bool | flippable = true | ) |
If a range is flippable, it will switch its direction if it is horizontal and its direction is Gtk::TextDirection::RTL.
See Gtk::Widget::get_direction().
- Parameters
-
flippable trueto make the range flippable.
| void Gtk::Range::set_increments | ( | double | step, |
| double | page | ||
| ) |
Sets the step and page sizes for the range.
The step size is used when the user clicks the Gtk::Scrollbar arrows or moves Gtk::Scale via arrow keys. The page size is used for example when moving via Page Up or Page Down keys.
- Parameters
-
step Step size. page Page size.
| void Gtk::Range::set_inverted | ( | bool | setting = true | ) |
Ranges normally move from lower to higher values as the slider moves from top to bottom or left to right.
Inverted ranges have higher values at the top or on the right rather than on the bottom or left.
- Parameters
-
setting trueto invert the range.
| void Gtk::Range::set_range | ( | double | min, |
| double | max | ||
| ) |
Sets the allowable values in the Gtk::Range, and clamps the range value to be between min and max.
(If the range has a non-zero page size, it is clamped between min and max - page-size.)
- Parameters
-
min Minimum range value. max Maximum range value.
| void Gtk::Range::set_restrict_to_fill_level | ( | bool | restrict_to_fill_level = true | ) |
Sets whether the slider is restricted to the fill level.
See set_fill_level() for a general description of the fill level concept.
- Parameters
-
restrict_to_fill_level Whether the fill level restricts slider movement.
| void Gtk::Range::set_round_digits | ( | int | round_digits | ) |
Sets the number of digits to round the value to when it changes.
See Gtk::Range::signal_change_value().
- Parameters
-
round_digits The precision in digits, or -1.
| void Gtk::Range::set_show_fill_level | ( | bool | show_fill_level = true | ) |
Sets whether a graphical fill level is show on the trough.
See set_fill_level() for a general description of the fill level concept.
- Parameters
-
show_fill_level Whether a fill level indicator graphics is shown.
| void Gtk::Range::set_slider_size_fixed | ( | bool | size_fixed = true | ) |
Sets whether the range’s slider has a fixed size, or a size that depends on its adjustment’s page size.
This function is useful mainly for Gtk::Range subclasses.
- Parameters
-
size_fixed trueto make the slider size constant.
| void Gtk::Range::set_value | ( | double | value | ) |
Sets the current value of the range; if the value is outside the minimum or maximum range values, it will be clamped to fit inside them.
The range emits the Gtk::Range::signal_value_changed() signal if the value changes.
- Parameters
-
value New value of the range.
| Glib::SignalProxy<void(double)> Gtk::Range::signal_adjust_bounds | ( | ) |
- Slot Prototype:
void on_my_adjust_bounds(double new_value)
Emitted before clamping a value, to give the application a chance to adjust the bounds.
- Parameters
-
new_value The value before we clamp.
| Glib::SignalProxy<bool(ScrollType, double)> Gtk::Range::signal_change_value | ( | ) |
- Slot Prototype:
bool on_my_change_value(ScrollType scroll, double new_value)
The Gtk::Range::signal_change_value() signal is emitted when a scroll action is performed on a range. It allows an application to determine the type of scroll event that occurred and the resultant new value. The application can handle the event itself and return true to prevent further processing. Or, by returning false, it can pass the event to other handlers until the default GTK+ handler is reached.
The value parameter is unrounded. An application that overrides the GtkRange::change-value signal is responsible for clamping the value to the desired number of decimal digits; the default GTK+ handler clamps the value based on Gtk::Range::property_round_digits().
- Parameters
-
scroll The type of scroll action that was performed. new_value The new value resulting from the scroll action.
- Returns
trueto prevent other handlers from being invoked for the signal,falseto propagate the signal further.
| Glib::SignalProxy<void(ScrollType)> Gtk::Range::signal_move_slider | ( | ) |
- Slot Prototype:
void on_my_move_slider(ScrollType scroll)
Virtual function that moves the slider. Used for keybindings.
- Parameters
-
scroll How to move the slider.
| Glib::SignalProxy<void()> Gtk::Range::signal_value_changed | ( | ) |
- Slot Prototype:
void on_my_value_changed()
Emitted when the range value changes.
| void Gtk::Range::unset_adjustment | ( | ) |
