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();

void* getStruct();

this(GtkHScale* gtkHScale);

void setStruct(GObject* obj);

this(Adjustment adjustment);

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

}

Constructors

this this(GtkHScale* gtkHScale): Sets our main struct and passes it to the parent class
this this(Adjustment adjustment): Warning gtk_hscale_new has been deprecated since version 3.2 and should not be used in newly-written code. Use gtk_scale_new() with GTK_ORIENTATION_HORIZONTAL instead Creates a new GtkHScale.
this this(double min, double max, double step): Warning gtk_hscale_new_with_range has been deprecated since version 3.2 and should not be used in newly-written code. Use gtk_scale_new_with_range() with GTK_ORIENTATION_HORIZONTAL instead 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. Note that the way in which the precision is derived works best if step is a power of ten. If the resulting precision is not suitable for your needs, use gtk_scale_set_digits() to correct it.

From Scale

gtkScale GtkScale* gtkScale;: the main Gtk struct
getScaleStruct GtkScale* getScaleStruct(): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
setStruct void setStruct(GObject* obj): Undocumented in source. Be warned that the author may not have intended to support it.
connectedSignals int[string] connectedSignals;
onFormatValueListeners string delegate(gdouble, Scale)[] onFormatValueListeners;: Undocumented in source.
addOnFormatValue void addOnFormatValue(string delegate(gdouble, 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. Here's an example signal handler which displays a value 1.0 as with "-->1.0<--".
callBackFormatValue void callBackFormatValue(GtkScale* scaleStruct, gdouble value, Scale _scale): Undocumented in source. Be warned that the author may not have intended to support it.
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 off to this number of digits, so the retrieved value matches the value the user saw.
setDrawValue void setDrawValue(int drawValue): Specifies whether the current value is displayed as a string next to the slider.
setHasOrigin void setHasOrigin(int hasOrigin): If has_origin is set to TRUE (the default), the scale will highlight the part of the scale between the origin (bottom or left side) of the scale and the current value.
setValuePos void setValuePos(GtkPositionType pos): Sets the position in which the current value is displayed.
getDigits int getDigits(): Gets the number of decimal places that are displayed in the value.
getDrawValue int getDrawValue(): Returns whether the current value is displayed as a string next to the slider.
getHasOrigin int getHasOrigin(): Returns whether the scale has an origin.
getValuePos GtkPositionType getValuePos(): Gets the position in which the current value is displayed.
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. Since 2.4
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. If the "draw-value" property is FALSE, the return values are undefined. Since 2.4
addMark void addMark(double value, GtkPositionType position, string markup): Adds a mark at value. A mark is indicated visually by drawing a tick mark next to the scale, and GTK+ makes it easy for the user to position the scale exactly at the marks value. If markup is not NULL, text is shown next to the tick mark. To remove marks from a scale, use gtk_scale_clear_marks(). Since 2.16
clearMarks void clearMarks(): Removes any marks that have been added with gtk_scale_add_mark(). Since 2.16
