Detailed Description

Regular image that works like a button.

Unlike the TextButton, this button doesn't draw anything on its own. It takes an existing graphic and treats it as a button, inverting colors when necessary. This is necessary for special buttons like in the Geoscape.

Constructor & Destructor Documentation

OpenXcom::ImageButton::ImageButton	(	int	width,
		int	height,
		int	x = 0,
		int	y = 0
	)

Creates a new image button with the specified size and position.

Sets up an image button with the specified size and position.

Parameters

width	Width in pixels.
height	Height in pixels.
x	X position in pixels.
y	Y position in pixels.

Gets the image button's color.

Returns the color for the image button.

Returns

Color value.

void OpenXcom::ImageButton::mousePress ( Action *  action, State *  state  )

virtual

Special handling for mouse presses.

Sets the button as the pressed button if it's part of a group, and inverts the colors when pressed.

void OpenXcom::ImageButton::setGroup

(

ImageButton **

group

)

Sets the image button's group.

Changes the button group this image button belongs to.

Parameters

Pointer to the pressed button pointer in the group. Null makes it a regular button.

void OpenXcom::ImageButton::toggle

(

bool

press

)

Invert a button explicitly either ON or OFF.

Invert a button explicitly either ON or OFF and keep track of the state using our internal variables.
