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.

class HScale : Scale {

protected

GtkHScale* gtkHScale;

GtkHScale* getHScaleStruct(bool transferOwnership);

void* getStruct();

this(GtkHScale* gtkHScale, bool ownedRef);

static GType getType();

this(Adjustment adjustment);

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

}

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 GtkScale* gtkScale;: the main Gtk struct
getScaleStruct GtkScale* getScaleStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
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.
