Protected Attributes inherited from GUI_BaseElement
GUI_ELEMENT_TYPE	type
	The type of this element.

RECT	rect
	Rect the element should draw on, relative to parent.

int	width
	The width of the element.

int	height
	The height of the element.

int	id
	The locally unique identifier of the element.

SURFHANDLE	src = NULL
	Source surface to draw the element on. When the element is drawn on the panel, it will be blitted from this surface.

bool	noBlitting = false
	Some elements might not have to blit themselves because they are static part of the background. This is not the same as !visible, as the element still processes events and still draws children, it just doesn't draw itself.

vector< GUI_BaseElement * >	children
	List containing all direct children of this element.

vector< GUIplugin * >	plugins
	List containing all GUIplugins currently pluged into this element.

GUI_font *	font
	The font used by this element.

GUI_ElementStyle *	style
	The style used by this element.

bool	visible
	Whether the element is visible or not (if false, element and any of its children will neither draw nor process events)

bool	isfixed = false
	Whether the element retains a fixed position in a scrolling frame.

Detailed Description

A label is a simple text on a single line without visible borders and without event handling

A labels text is unchangable during its lifetime.

Note: The labels text will be horizontally and vertically centered in its rect.

Constructor & Destructor Documentation

GUI_Label::GUI_Label	(	string	_text,
		RECT	_rect,
		int	_id,
		GUI_ElementStyle *	_style
	)

Parameters

_text	The text to be displayed as label
_rect	Parent-relative position and dimensions
_id	Identifier of the element, locally unique to the containing GUIentity
_style	The style to render the checkbox in

Member Function Documentation

void GUI_Label::ChangeText ( string text )

Sets a new text for the label.

This should NOT be used to display frequently updating text, much less anything that updates by the frame. The source surface is destroyed and allocated anew, so this is actually MORE expensive than blitting dynamic text to the screen. Use it if the text is generally static, but has to change at one point or another over the lifetime of the element.

Parameters

text	The new text the label should display

void GUI_Label::DrawMe	(	SURFHANDLE	_tgt,
		int	xoffset,
		int	yoffset,
		RECT &	drawablerect
	)

privatevirtual

Draws this element.

Separated from DrawChildren so it can be freely overloaded

Parameters

_tgt	The target surface to draw to
xoffset	The offset between this element rects left edge and the left panel edge, in pixel
yoffset	The offset between this element rects top edge and the top panel edge, in pixel
drawablerect	The total drawable rect of this element. Serves as clipping rect.

Reimplemented from GUI_BaseElement.
