static WidgetSpinBoxPtr create ( const Ptr<Gui> & gui, int min = 0, int max = 100, int value = 0, int step = 1 ) #

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

static WidgetSpinBoxPtr create ( int min = 0, int max = 100, int value = 0, int step = 1 ) #

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

Arguments

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

void setMaxExpand ( int expand ) #

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

Arguments

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

int 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 ( int value ) #

Sets a maximum value of the spinbox.

Arguments

• int value - Maximum spinbox value.

int getMaxValue ( ) const#

Returns a maximum value of the spinbox.

Return value

Maximum spinbox value.

void setMinExpand ( int expand ) #

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

Arguments

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

int 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 ( int value ) #

Sets a minimum value of the spinbox.

Arguments

• int value - Minimum spinbox value.

int getMinValue ( ) const#

Returns a minimum value of the spinbox.

Return value

Minimum spinbox value.

void setValue ( int value ) #

Updates the current value of the spinbox.

Arguments

• int value - New spinbox value.

int getValue ( ) const#

Returns the current value of the spinbox.

Return value

Current spinbox value.

void setStep ( int step ) #

Updates the current step of the spinbox.

Arguments

• int step - New spinbox step.

int 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.
