Unigine::WidgetSpinBoxDouble Class

Header: #include <UnigineWidgets.h>
Inherits from: Widget

This class creates a spin box with double values.

Usage Example#

This example illustrates creation of a spinbox via code.

Source code (C++)
// AppWorldLogic.cpp

// including necessary headers and declaring a spinbox
#include <UnigineWidgets.h>
#include <UnigineGUI.h>
using namespace Unigine;
WidgetSpinBoxDoublePtr spinbox;

// ...

// callback to be fired on changing spinbox value
void sbChanged(Unigine::Ptr<Widget> widget) {
	WidgetSpinBoxDoublePtr sb = widget;
	
	// printing the current spinbox value to the console
	Log::message("Spinbox value changed: %d \n", sb->getValue());
}

// Method creating a spinbox with specified parameters at the specified position
WidgetSpinBoxDoublePtr createSB(double x, double y, double min, double max, double value, double step)
{
	// creating a new edit line and adding it to the GUI
	WidgetEditLinePtr new_el = WidgetEditLine::create(Gui::get());
	Gui::get()->addChild(new_el, Gui::ALIGN_OVERLAP);
	
	// setting widget's position
	new_el->setPosition(x, y);
	
	// creating a spinbox with the specified parameters and adding it to the GUI
	WidgetSpinBoxDoublePtr new_sb = WidgetSpinBoxDouble::create(Gui::get(), min, max, value, step);
	Gui::get()->addChild(new_sb, Gui::ALIGN_OVERLAP);

	// adding a callback to be fired on changing spinbox value
	new_sb->addCallback(Gui::CHANGED, MakeCallback(sbChanged));
	new_sb->setOrder(1);
	
	// attaching the spinbox to the edit line
	new_el->addAttach(new_sb);
	
	// setting initial spinbox value
	new_sb->setValue(value);

	return new_sb;
}

// ...

int AppWorldLogic::init()
{
	// creating a spinbox with values in [0.0, 10.0] range (current - 5.0) with step 1.0 at position (100, 100)
	spinbox = createSB(100, 100, 0.0, 10.0, 5.0, 1.0);
	return 1;
}

// ...

int AppWorldLogic::shutdown()
{
	// cleanup
	spinbox.destroy();
	return 1;
}

// ...

Members


static WidgetSpinBoxDoublePtr create ( const Ptr<Gui> & gui, double min = 0.0, double max = 100.0, double value = 0.0, double step = 1.0 ) #

Constructor. Creates a spinbox with given parameters and adds it to the specified GUI.

Arguments

  • const Ptr<Gui> & gui - GUI, to which the spinbox will belong.
  • double min - Minimum value.
  • double max - Maximum value.
  • double value - Initial value.
  • double step - Initial step.

static WidgetSpinBoxDoublePtr create ( double min = 0.0, double max = 100.0, double value = 0.0, double step = 1.0 ) #

Constructor. Creates a spinbox with given parameters and adds it to the Engine GUI.

Arguments

  • double min - Minimum value.
  • double max - Maximum value.
  • double value - Initial value.
  • double step - Initial step.

void setMaxExpand ( double expand ) #

Sets the maximum value, up to which the upper limit of the range of the spinbox values can be expanded.

Arguments

  • double expand - Maximum value, up to which the spinbox upper limit can be raised.

double getMaxExpand ( ) const#

Returns the current maximum value, up to which the upper limit of the range of the spinbox values can be expanded. The upper limit of the spinbox can be expanded only if the spinbox is attached to an editline with the Gui::ATTACH_MAX_EXPAND flag.

Return value

Maximum value, up to which the spinbox upper limit can be raised.

void setMaxValue ( double value ) #

Sets a maximum value of the spinbox.

Arguments

  • double value - Maximum spinbox value.

double getMaxValue ( ) const#

Returns a maximum value of the spinbox.

Return value

Maximum spinbox value.

void setMinExpand ( double expand ) #

Sets the minimum value, up to which the lower limit of the range of the spinbox values can be expanded.

Arguments

  • double expand - Minimum value, up to which the spinbox lower limit can be dropped.

double getMinExpand ( ) const#

Returns the current minimum value, up to which the lower limit of the range of the spinbox values can be expanded. The lower limit of the spinbox can be expanded only if the spinbox is attached to an editline with the Gui::ATTACH_MIN_EXPAND flag.

Return value

Minimum value, up to which the spinbox lower limit can be dropped.

void setMinValue ( double value ) #

Sets a minimum value of the spinbox.

Arguments

  • double value - Minimum spinbox value.

double getMinValue ( ) const#

Returns a minimum value of the spinbox.

Return value

Minimum spinbox value.

void setValue ( double value ) #

Updates the current value of the spinbox.

Arguments

  • double value - New spinbox value.

double getValue ( ) const#

Returns the current value of the spinbox.

Return value

Current spinbox value.

void setStep ( double step ) #

Updates the current step of the spinbox.

Arguments

  • double step - New spinbox step.

double getStep ( ) const#

Returns the current step of the spinbox.

Return value

Current spinbox step.

void setButtonColor ( const Math::vec4 & color ) #

Sets the color for the widget's button.

Arguments

  • const Math::vec4 & color - Four-component vector specifying the color in the RGBA format.

Math::vec4 getButtonColor ( ) const#

Returns the current color for the widget's button.

Return value

Four-component vector specifying the color in the RGBA format.
