Adjustment

gtk.adjustment.Adjustment is a model for a numeric value.

The gtk.adjustment.Adjustment has an associated lower and upper bound. It also contains step and page increments, and a page size.

Adjustments are used within several GTK widgets, including gtk.spin_button.SpinButton, gtk.viewport.Viewport, gtk.scrollbar.Scrollbar and gtk.scale.Scale.

The gtk.adjustment.Adjustment object does not update the value itself. Instead it is left up to the owner of the gtk.adjustment.Adjustment to control the value.

class Adjustment : InitiallyUnowned {

this(double value, double lower, double upper, double stepIncrement, double pageIncrement, double pageSize);

void clampPage(double lower, double upper);

void configure(double value, double lower, double upper, double stepIncrement, double pageIncrement, double pageSize);

double getLower();

double getMinimumIncrement();

double getPageIncrement();

double getPageSize();

double getStepIncrement();

double getUpper();

double getValue();

void setLower(double lower);

void setPageIncrement(double pageIncrement);

void setPageSize(double pageSize);

void setStepIncrement(double stepIncrement);

void setUpper(double upper);

void setValue(double value);

ulong connectChanged(T callback, Flag!"After" after);

ulong connectValueChanged(T callback, Flag!"After" after);

}

Constructors

this this(double value, double lower, double upper, double stepIncrement, double pageIncrement, double pageSize): Creates a new gtk.adjustment.Adjustment.

Functions

clampPage void clampPage(double lower, double upper): Updates the value property to ensure that the range between lower and upper is 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 ulong connectChanged(T callback, Flag!"After" after): Connect to Changed signal.
connectValueChanged ulong 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.
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 gtk.adjustment.Adjustment value.
