Class

GtkVScale

Description [src]

class Gtk.VScale : Gtk.Scale {
  scale: GtkScale
}

The GtkVScale widget is used to allow the user to select a value using a vertical slider. To create one, use gtk_hscale_new_with_range().

The position to show the current value, and the number of decimal places shown can be set using the parent GtkScale class’s functions.

GtkVScale has been deprecated, use GtkScale instead.

Constructors

gtk_vscale_new

Creates a new GtkVScale.

Deprecated since: 3.2

gtk_vscale_new_with_range

Creates a new vertical scale widget that lets the user input a number between min and max (including min and max) with the increment step. step must be nonzero; it’s the distance the slider moves when using the arrow keys to adjust the scale value.

Deprecated since: 3.2

Instance methods

Methods inherited from GtkScale (12)
gtk_scale_add_mark

Adds a mark at value.

Available since: 2.16

gtk_scale_clear_marks

Removes any marks that have been added with gtk_scale_add_mark().

Available since: 2.16

gtk_scale_get_digits

Gets the number of decimal places that are displayed in the value.

gtk_scale_get_draw_value

Returns whether the current value is displayed as a string next to the slider.

gtk_scale_get_has_origin

Returns whether the scale has an origin.

Available since: 3.4

gtk_scale_get_layout

Gets the PangoLayout used to display the scale. The returned object is owned by the scale so does not need to be freed by the caller.

Available since: 2.4

gtk_scale_get_layout_offsets

Obtains the coordinates where the scale will draw the PangoLayout representing the text in the scale. Remember when using the PangoLayout function you need to convert to and from pixels using PANGO_PIXELS() or #PANGO_SCALE.

Available since: 2.4

gtk_scale_get_value_pos

Gets the position in which the current value is displayed.

gtk_scale_set_digits

Sets the number of decimal places that are displayed in the value. Also causes the value of the adjustment to be rounded to this number of digits, so the retrieved value matches the displayed one, if GtkScale:draw-value is TRUE when the value changes. If you want to enforce rounding the value when GtkScale:draw-value is FALSE, you can set GtkRange:round-digits instead.

gtk_scale_set_draw_value

Specifies whether the current value is displayed as a string next to the slider.

gtk_scale_set_has_origin

If GtkScale:has-origin is set to TRUE (the default), the scale will highlight the part of the trough between the origin (bottom or left side) and the current value.

Available since: 3.4

gtk_scale_set_value_pos

Sets the position in which the current value is displayed.

Methods inherited from GtkRange (28)
gtk_range_get_adjustment

Get the GtkAdjustment which is the “model” object for GtkRange. See gtk_range_set_adjustment() for details. The return value does not have a reference added, so should not be unreferenced.

gtk_range_get_fill_level

Gets the current position of the fill level indicator.

Available since: 2.12

gtk_range_get_flippable

Gets the value set by gtk_range_set_flippable().

Gets the sensitivity policy for the stepper that points to the ‘lower’ end of the GtkRange’s adjustment.

Available since: 2.10

gtk_range_get_min_slider_size

This function is useful mainly for GtkRange subclasses.

Available since: 2.20

Deprecated since: 3.20

gtk_range_get_range_rect

This function returns the area that contains the range’s trough and its steppers, in widget->window coordinates.

Available since: 2.20

gtk_range_get_restrict_to_fill_level

Gets whether the range is restricted to the fill level.

Available since: 2.12

gtk_range_get_round_digits

Gets the number of digits to round the value to when it changes. See GtkRange::change-value.

Available since: 2.24

gtk_range_get_show_fill_level

Gets whether the range displays the fill level graphically.

Available since: 2.12

gtk_range_get_slider_range

This function returns sliders range along the long dimension, in widget->window coordinates.

Available since: 2.20

gtk_range_get_slider_size_fixed

This function is useful mainly for GtkRange subclasses.

Available since: 2.20

gtk_range_get_upper_stepper_sensitivity

Gets the sensitivity policy for the stepper that points to the ‘upper’ end of the GtkRange’s adjustment.

Available since: 2.10

gtk_range_get_value

Gets the current value of the range.

gtk_range_set_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 GtkScale and nonzero for GtkScrollbar, and indicates the size of the visible area of the widget being scrolled. The page size affects the size of the scrollbar slider.

gtk_range_set_fill_level

Set the new position of the fill level indicator.

Available since: 2.12

gtk_range_set_flippable

If a range is flippable, it will switch its direction if it is horizontal and its direction is GTK_TEXT_DIR_RTL.

Available since: 2.18

gtk_range_set_increments

Sets the step and page sizes for the range. The step size is used when the user clicks the GtkScrollbar arrows or moves GtkScale via arrow keys. The page size is used for example when moving via Page Up or Page Down keys.

gtk_range_set_inverted

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.

gtk_range_set_lower_stepper_sensitivity

Sets the sensitivity policy for the stepper that points to the ‘lower’ end of the GtkRange’s adjustment.

Available since: 2.10

gtk_range_set_min_slider_size

Sets the minimum size of the range’s slider.

Available since: 2.20

Deprecated since: 3.20

gtk_range_set_range

Sets the allowable values in the GtkRange, 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.)

gtk_range_set_restrict_to_fill_level

Sets whether the slider is restricted to the fill level. See gtk_range_set_fill_level() for a general description of the fill level concept.

Available since: 2.12

Methods inherited from GtkWidget (263)
gtk_widget_activate

For widgets that can be “activated” (buttons, menu items, etc.) this function activates them. Activation is what happens when you press Enter on a widget during key navigation. If widget isn’t activatable, the function returns FALSE.

gtk_widget_add_accelerator

Installs an accelerator for this widget in accel_group that causes accel_signal to be emitted if the accelerator is activated. The accel_group needs to be added to the widget’s toplevel via gtk_window_add_accel_group(), and the signal must be of type G_SIGNAL_ACTION. Accelerators added through this function are not user changeable during runtime. If you want to support accelerators that can be changed by the user, use gtk_accel_map_add_entry() and gtk_widget_set_accel_path() or gtk_menu_item_set_accel_path() instead.

gtk_widget_add_device_events

Adds the device events in the bitfield events to the event mask for widget. See gtk_widget_set_device_events() for details.

Available since: 3.0

gtk_widget_add_events

Adds the events in the bitfield events to the event mask for widget. See gtk_widget_set_events() and the [input handling overview][event-masks] for details.

gtk_widget_add_mnemonic_label

Adds a widget to the list of mnemonic labels for this widget. (See gtk_widget_list_mnemonic_labels()). Note the list of mnemonic labels for the widget is cleared when the widget is destroyed, so the caller must make sure to update its internal state at this point as well, by using a connection to the GtkWidget::destroy signal or a weak notifier.

Available since: 2.4

gtk_widget_add_tick_callback

Queues an animation frame update and adds a callback to be called before each frame. Until the tick callback is removed, it will be called frequently (usually at the frame rate of the output device or as quickly as the application can be repainted, whichever is slower). For this reason, is most suitable for handling graphics that change every frame or every few frames. The tick callback does not automatically imply a relayout or repaint. If you want a repaint or relayout, and aren’t changing widget properties that would trigger that (for example, changing the text of a GtkLabel), then you will have to call gtk_widget_queue_resize() or gtk_widget_queue_draw_area() yourself.

Available since: 3.8

gtk_widget_can_activate_accel

Determines whether an accelerator that activates the signal identified by signal_id can currently be activated. This is done by emitting the GtkWidget::can-activate-accel signal on widget; if the signal isn’t overridden by a handler or in a derived widget, then the default check is that the widget must be sensitive, and the widget and all its ancestors mapped.

Available since: 2.4

gtk_widget_child_focus

This function is used by custom widget implementations; if you’re writing an app, you’d use gtk_widget_grab_focus() to move the focus to a particular widget, and gtk_container_set_focus_chain() to change the focus tab order. So you may want to investigate those functions instead.

gtk_widget_child_notify

Emits a GtkWidget::child-notify signal for the [child property][child-properties] child_property on widget.

gtk_widget_class_path

Same as gtk_widget_path(), but always uses the name of a widget’s type, never uses a custom name set with gtk_widget_set_name().

Deprecated since: 3.0

gtk_widget_compute_expand

Computes whether a container should give this widget extra space when possible. Containers should check this, rather than looking at gtk_widget_get_hexpand() or gtk_widget_get_vexpand().

gtk_widget_create_pango_context

Creates a new PangoContext with the appropriate font map, font options, font description, and base direction for drawing text for this widget. See also gtk_widget_get_pango_context().

gtk_widget_create_pango_layout

Creates a new PangoLayout with the appropriate font map, font description, and base direction for drawing text for this widget.

gtk_widget_destroy

Destroys a widget.

gtk_widget_destroyed

This function sets *widget_pointer to NULL if widget_pointer != NULL. It’s intended to be used as a callback connected to the “destroy” signal of a widget. You connect gtk_widget_destroyed() as a signal handler, and pass the address of your widget variable as user data. Then when the widget is destroyed, the variable will be set to NULL. Useful for example to avoid multiple copies of the same dialog.

gtk_widget_device_is_shadowed

Returns TRUE if device has been shadowed by a GTK+ device grab on another widget, so it would stop sending events to widget. This may be used in the GtkWidget::grab-notify signal to check for specific devices. See gtk_device_grab_add().

Available since: 3.0

gtk_drag_begin

This function is equivalent to gtk_drag_begin_with_coordinates(), passing -1, -1 as coordinates.

Deprecated since: 3.10

gtk_drag_begin_with_coordinates

Initiates a drag on the source side. The function only needs to be used when the application is starting drags itself, and is not needed when gtk_drag_source_set() is used.

Available since: 3.10

gtk_drag_check_threshold

Checks to see if a mouse drag starting at (start_x, start_y) and ending at (current_x, current_y) has passed the GTK+ drag threshold, and thus should trigger the beginning of a drag-and-drop operation.

gtk_drag_dest_add_image_targets

Add the image targets supported by GtkSelectionData to the target list of the drag destination. The targets are added with info = 0. If you need another value, use gtk_target_list_add_image_targets() and gtk_drag_dest_set_target_list().

Available since: 2.6

gtk_drag_dest_add_text_targets

Add the text targets supported by GtkSelectionData to the target list of the drag destination. The targets are added with info = 0. If you need another value, use gtk_target_list_add_text_targets() and gtk_drag_dest_set_target_list().

Available since: 2.6

gtk_drag_dest_add_uri_targets

Add the URI targets supported by GtkSelectionData to the target list of the drag destination. The targets are added with info = 0. If you need another value, use gtk_target_list_add_uri_targets() and gtk_drag_dest_set_target_list().

Available since: 2.6

gtk_drag_dest_find_target

Looks for a match between the supported targets of context and the dest_target_list, returning the first matching target, otherwise returning GDK_NONE. dest_target_list should usually be the return value from gtk_drag_dest_get_target_list(), but some widgets may have different valid targets for different parts of the widget; in that case, they will have to implement a drag_motion handler that passes the correct target list to this function.

Signals

Signals inherited from GtkScale (1)
Gtk.Scale::format-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.

Signals inherited from GtkRange (4)
Gtk.Range::adjust-bounds

Emitted before clamping a value, to give the application a chance to adjust the bounds.

Gtk.Range::change-value

The GtkRange::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.

Available since: 2.6

Gtk.Range::move-slider

Virtual function that moves the slider. Used for keybindings.

Gtk.Range::value-changed

Emitted when the range value changes.

Signals inherited from GtkWidget (69)
Gtk.Widget::accel-closures-changed
No description available.
Gtk.Widget::button-press-event

The ::button-press-event signal will be emitted when a button (typically from a mouse) is pressed.

Gtk.Widget::button-release-event

The ::button-release-event signal will be emitted when a button (typically from a mouse) is released.

Gtk.Widget::can-activate-accel

Determines whether an accelerator that activates the signal identified by signal_id can currently be activated. This signal is present to allow applications and derived widgets to override the default GtkWidget handling for determining whether an accelerator can be activated.

Gtk.Widget::child-notify

The ::child-notify signal is emitted for each [child property][child-properties] that has changed on an object. The signal’s detail holds the property name.

Gtk.Widget::composited-changed

The ::composited-changed signal is emitted when the composited status of widgets screen changes. See gdk_screen_is_composited().

Deprecated since: 3.22

Gtk.Widget::configure-event

The ::configure-event signal will be emitted when the size, position or stacking of the widgets window has changed.

Gtk.Widget::damage-event

Emitted when a redirected window belonging to widget gets drawn into. The region/area members of the event shows what area of the redirected drawable was drawn into.

Available since: 2.14

Gtk.Widget::delete-event

The ::delete-event signal is emitted if a user requests that a toplevel window is closed. The default handler for this signal destroys the window. Connecting gtk_widget_hide_on_delete() to this signal will cause the window to be hidden instead, so that it can later be shown again without reconstructing it.

Gtk.Widget::destroy

Signals that all holders of a reference to the widget should release the reference that they hold. May result in finalization of the widget if all references are released.

Gtk.Widget::destroy-event

The ::destroy-event signal is emitted when a GdkWindow is destroyed. You rarely get this signal, because most widgets disconnect themselves from their window before they destroy it, so no widget owns the window at destroy time.

Gtk.Widget::direction-changed

The ::direction-changed signal is emitted when the text direction of a widget changes.

Gtk.Widget::drag-begin

The ::drag-begin signal is emitted on the drag source when a drag is started. A typical reason to connect to this signal is to set up a custom drag icon with e.g. gtk_drag_source_set_icon_pixbuf().

Gtk.Widget::drag-data-delete

The ::drag-data-delete signal is emitted on the drag source when a drag with the action GDK_ACTION_MOVE is successfully completed. The signal handler is responsible for deleting the data that has been dropped. What “delete” means depends on the context of the drag operation.

Gtk.Widget::drag-data-get

The ::drag-data-get signal is emitted on the drag source when the drop site requests the data which is dragged. It is the responsibility of the signal handler to fill data with the data in the format which is indicated by info. See gtk_selection_data_set() and gtk_selection_data_set_text().

Gtk.Widget::drag-data-received

The ::drag-data-received signal is emitted on the drop site when the dragged data has been received. If the data was received in order to determine whether the drop will be accepted, the handler is expected to call gdk_drag_status() and not finish the drag. If the data was received in response to a GtkWidget::drag-drop signal (and this is the last target to be received), the handler for this signal is expected to process the received data and then call gtk_drag_finish(), setting the success parameter depending on whether the data was processed successfully.

Gtk.Widget::drag-drop

The ::drag-drop signal is emitted on the drop site when the user drops the data onto the widget. The signal handler must determine whether the cursor position is in a drop zone or not. If it is not in a drop zone, it returns FALSE and no further processing is necessary. Otherwise, the handler returns TRUE. In this case, the handler must ensure that gtk_drag_finish() is called to let the source know that the drop is done. The call to gtk_drag_finish() can be done either directly or in a GtkWidget::drag-data-received handler which gets triggered by calling gtk_drag_get_data() to receive the data for one or more of the supported targets.

Gtk.Widget::drag-end

The ::drag-end signal is emitted on the drag source when a drag is finished. A typical reason to connect to this signal is to undo things done in GtkWidget::drag-begin.

Gtk.Widget::drag-failed

The ::drag-failed signal is emitted on the drag source when a drag has failed. The signal handler may hook custom code to handle a failed DnD operation based on the type of error, it returns TRUE is the failure has been already handled (not showing the default “drag operation failed” animation), otherwise it returns FALSE.

Available since: 2.12

Gtk.Widget::drag-leave

The ::drag-leave signal is emitted on the drop site when the cursor leaves the widget. A typical reason to connect to this signal is to undo things done in GtkWidget::drag-motion, e.g. undo highlighting with gtk_drag_unhighlight().

Gtk.Widget::drag-motion

The ::drag-motion signal is emitted on the drop site when the user moves the cursor over the widget during a drag. The signal handler must determine whether the cursor position is in a drop zone or not. If it is not in a drop zone, it returns FALSE and no further processing is necessary. Otherwise, the handler returns TRUE. In this case, the handler is responsible for providing the necessary information for displaying feedback to the user, by calling gdk_drag_status().

Gtk.Widget::draw

This signal is emitted when a widget is supposed to render itself. The widgets top left corner must be painted at the origin of the passed in context and be sized to the values returned by gtk_widget_get_allocated_width() and gtk_widget_get_allocated_height().

Available since: 3.0

Gtk.Widget::enter-notify-event

The ::enter-notify-event will be emitted when the pointer enters the widgets window.

Gtk.Widget::event

The GTK+ main loop will emit three signals for each GDK event delivered to a widget: one generic ::event signal, another, more specific, signal that matches the type of event delivered (e.g. GtkWidget::key-press-event) and finally a generic GtkWidget::event-after signal.

Gtk.Widget::event-after

After the emission of the GtkWidget::event signal and (optionally) the second more specific signal, ::event-after will be emitted regardless of the previous two signals handlers return values.

Gtk.Widget::focus
No description available.
Gtk.Widget::focus-in-event

The ::focus-in-event signal will be emitted when the keyboard focus enters the widgets window.

Gtk.Widget::focus-out-event

The ::focus-out-event signal will be emitted when the keyboard focus leaves the widgets window.

Gtk.Widget::grab-broken-event

Emitted when a pointer or keyboard grab on a window belonging to widget gets broken.

Available since: 2.8

Gtk.Widget::grab-focus
No description available.
Gtk.Widget::grab-notify

The ::grab-notify signal is emitted when a widget becomes shadowed by a GTK+ grab (not a pointer or keyboard grab) on another widget, or when it becomes unshadowed due to a grab being removed.

Gtk.Widget::hide

The ::hide signal is emitted when widget is hidden, for example with gtk_widget_hide().

Gtk.Widget::hierarchy-changed

The ::hierarchy-changed signal is emitted when the anchored state of a widget changes. A widget is “anchored” when its toplevel ancestor is a GtkWindow. This signal is emitted when a widget changes from un-anchored to anchored or vice-versa.

Gtk.Widget::key-press-event

The ::key-press-event signal is emitted when a key is pressed. The signal emission will reoccur at the key-repeat rate when the key is kept pressed.

Gtk.Widget::key-release-event

The ::key-release-event signal is emitted when a key is released.

Gtk.Widget::keynav-failed

Gets emitted if keyboard navigation fails. See gtk_widget_keynav_failed() for details.

Available since: 2.12

Gtk.Widget::leave-notify-event

The ::leave-notify-event will be emitted when the pointer leaves the widgets window.

Gtk.Widget::map

The ::map signal is emitted when widget is going to be mapped, that is when the widget is visible (which is controlled with gtk_widget_set_visible()) and all its parents up to the toplevel widget are also visible. Once the map has occurred, GtkWidget::map-event will be emitted.
