HScale

The #GtkHScale widget is used to allow the user to select a value using a horizontal 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.

GtkHScale has been deprecated, use #GtkScale instead.

Constructors

this
this(GtkHScale* gtkHScale, bool ownedRef)

Sets our main struct and passes it to the parent class.

this
this(Adjustment adjustment)

Creates a new #GtkHScale.

this
this(double min, double max, double step)

Creates a new horizontal 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.

From Scale

gtkScale

getScaleStruct
GtkScale* getScaleStruct(bool transferOwnership)

Get the main Gtk struct

getStruct
void* getStruct()

getType
GType getType()
addMark
void addMark(double value, GtkPositionType position, string markup)

Adds a mark at @value.

clearMarks
void clearMarks()

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

getDigits
int getDigits()

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

getDrawValue
bool getDrawValue()

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

getHasOrigin
bool getHasOrigin()

Returns whether the scale has an origin.

getLayout
PgLayout getLayout()

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.

getLayoutOffsets
void getLayoutOffsets(int x, int y)

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.

getValuePos
GtkPositionType getValuePos()

Gets the position in which the current value is displayed.

setDigits
void setDigits(int 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.

setDrawValue
void setDrawValue(bool drawValue)

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

setHasOrigin
void setHasOrigin(bool hasOrigin)

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.

setValuePos
void setValuePos(GtkPositionType pos)

Sets the position in which the current value is displayed.

addOnFormatValue
gulong addOnFormatValue(string delegate(double, Scale) dlg, ConnectFlags connectFlags)

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.
