	)

Completely fills the cairo with the specified style.

Parameters

cairo_ptr	A cairo, backed by an image surface.
fill_ptr

wlmaker_primitives_cairo_fill_at()

void wlmaker_primitives_cairo_fill_at	(	cairo_t *	cairo_ptr,
		int	x,
		int	y,
		unsigned	width,
		unsigned	height,
		const wlmtk_style_fill_t *	fill_ptr
	)

Fills the cairo with the specified style at the specified rectangle.

Parameters

wlmaker_primitives_draw_bezel()

void wlmaker_primitives_draw_bezel	(	cairo_t *	cairo_ptr,
		double	bezel_width,
		bool	raised
	)

Draws a bezel into the cairo.

Parameters

wlmaker_primitives_draw_bezel_at()

void wlmaker_primitives_draw_bezel_at	(	cairo_t *	cairo_ptr,
		int	x,
		int	y,
		unsigned	width,
		unsigned	height,
		double	bezel_width,
		bool	raised
	)

Draws a bezel into the cairo, at specified position and width/height.

Parameters

cairo_ptr	A cairo, backed by an image surface.
x
y
width
height
bezel_width
raised	Whether the bezel is to highlight a raised (true) or pressed (false) state.

wlmaker_primitives_draw_close_icon()

void wlmaker_primitives_draw_close_icon	(	cairo_t *	cairo_ptr,
		int	size,
		uint32_t	color
	)

Draws the "close" icon, as used in the title bar.

Parameters

cairo_ptr
size
color

wlmaker_primitives_draw_minimize_icon()

void wlmaker_primitives_draw_minimize_icon	(	cairo_t *	cairo_ptr,
		int	size,
		uint32_t	color
	)

Draws the "minimize" icon, as used in the title bar.

Parameters

cairo_ptr
size
color

wlmaker_primitives_draw_text()

void wlmaker_primitives_draw_text	(	cairo_t *	cairo_ptr,
		int	x,
		int	y,
		const wlmtk_style_font_t *	font_style_ptr,
		uint32_t	color,
		const char *	text_ptr
	)

Draws the text with given parameters into the cairo_t at (x, y).

Parameters

cairo_ptr
x
y
font_style_ptr
color
text_ptr

wlmaker_primitives_draw_window_title()

void wlmaker_primitives_draw_window_title	(	cairo_t *	cairo_ptr,
		const wlmtk_style_font_t *	font_style_ptr,
		const char *	title_ptr,
		uint32_t	color
	)

Draws the window title into the cairo_t.

Parameters

cairo_ptr
font_style_ptr	The font style to use.
title_ptr	Title string, or NULL.
color	As an ARGB 8888 value.

wlmaker_primitives_set_bezel_color()

void wlmaker_primitives_set_bezel_color	(	cairo_t *	cairo_ptr,
		bool	illuminated
	)

Sets the bezel color.

Note: Window Maker draws the bezel by adding 80 (0x50) to each R, G, B of the underlying title for the illuminated side; respectively by subtracting 40 (0x28) on the non-illuminated side. We are using cairo's overlaying with the respective "alpha" values below, which leads to different results.

Parameters

cairo_ptr
illuminated
