Adjustment

The #GtkAdjustment object represents a value which has an associated lower and upper bound, together with step and page increments, and a page size. It is used within several GTK+ widgets, including #GtkSpinButton, #GtkViewport, and #GtkRange (which is a base class for #GtkScrollbar and #GtkScale).

The #GtkAdjustment object does not update the value itself. Instead it is left up to the owner of the #GtkAdjustment to control the value.

Functions

changed void changed(): Emits a #GtkAdjustment::changed signal from the #GtkAdjustment. This is typically called by the owner of the #GtkAdjustment after it has changed any of the #GtkAdjustment properties other than the value.
clampPage void clampPage(double lower, double upper): Updates the #GtkAdjustment:value property to ensure that the range between lower and upper is in the current page (i.e. between #GtkAdjustment:value and #GtkAdjustment:value + #GtkAdjustment:page-size). If the range is larger than the page size, then only the start of it will be in the current page.
configure void configure(double value, double lower, double upper, double stepIncrement, double pageIncrement, double pageSize): Sets all properties of the adjustment at once.
connectChanged gulong connectChanged(T callback, Flag!"After" after): Connect to Changed signal.
connectValueChanged gulong connectValueChanged(T callback, Flag!"After" after): Connect to ValueChanged signal.
getLower double getLower(): Retrieves the minimum value of the adjustment.
getMinimumIncrement double getMinimumIncrement(): Gets the smaller of step increment and page increment.
getPageIncrement double getPageIncrement(): Retrieves the page increment of the adjustment.
getPageSize double getPageSize(): Retrieves the page size of the adjustment.
getStepIncrement double getStepIncrement(): Retrieves the step increment of the adjustment.
getUpper double getUpper(): Retrieves the maximum value of the adjustment.
getValue double getValue(): Gets the current value of the adjustment. See gtk.adjustment.Adjustment.setValue.
self Adjustment self(): Returns this, for use in with statements.
setLower void setLower(double lower): Sets the minimum value of the adjustment.
setPageIncrement void setPageIncrement(double pageIncrement): Sets the page increment of the adjustment.
setPageSize void setPageSize(double pageSize): Sets the page size of the adjustment.
setStepIncrement void setStepIncrement(double stepIncrement): Sets the step increment of the adjustment.
setUpper void setUpper(double upper): Sets the maximum value of the adjustment.
setValue void setValue(double value): Sets the #GtkAdjustment value. The value is clamped to lie between #GtkAdjustment:lower and #GtkAdjustment:upper.
valueChanged void valueChanged(): Emits a #GtkAdjustment::value-changed signal from the #GtkAdjustment. This is typically called by the owner of the #GtkAdjustment after it has changed the #GtkAdjustment:value property.
