Get the Gtk::Adjustment which is the "model" object for Gtk::Range. See set_adjustment() for details. The return value does not have a reference added, so should not be unreferenced.

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.
|
|
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.
|
|
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.
|
|
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.)
|
|
Sets the update policy for the range. Gtk::UPDATE_CONTINUOUS means that anytime the range slider is moved, the range value will change and the value_changed signal will be emitted. Gtk::UPDATE_DELAYED means that the value will be updated after a brief timeout where no slider motion occurs, so updates are spaced by a short time rather than continuous. Gtk::UPDATE_DISCONTINUOUS means that the value will only be updated when the user releases the button and ends the slider drag operation.
|
|
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 "value_changed" signal if the value changes.
|
|
|
|
The 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 change_value signal is responsible for clamping the value to the desired number of decimal digits; the default handler clamps the value based on range->round_digits. It is not possible to use delayed update policies in an overridden change_value handler.
