Draw a beveled box
int PgDrawBevelBox( PhRect_t const *rect,
PgColor_t secondary,
short width,
int flags );
int PgDrawIBevelBox( int x1, int y1,
int x2, int y2,
PgColor_t secondary,
short width,
int flags );
int PgDrawBevelBoxCx( void *dc,
PhRect_t const *rect,

int PgDrawIBevelBoxCx( void *dc,

int x2, int y2,
PgColor_t secondary,

int flags );
- dc
- PgDrawBevelBoxCx() and PgDrawIBevelBoxCx() only.
A void pointer to any type of draw context. Examples of draw contexts are:
- rect (PgDrawBevelBox() and PgDrawBevelBoxCx() only)
- A rectangle that describes the size of the bevel box.
- x1, x2, y1, y2 (PgDrawIBevelBox() and PgDrawIBevelBoxCx() only)
- The coordinates of the top left (x1, y1) and bottom right (x2, y2) of the bevel box.
- secondary
- The color of the lower and right edges of the bevel box. The top and left edges are drawn with the current stroke color.
- width
- The thickness of the lines.
- flags
- One of the following:
- Pg_DRAW_STROKE — draw as a line.
- Pg_DRAW_FILL — fill the box.
- Pg_DRAW_FILL_STROKE — fill the box, then stroke it.
The flags argument must be one of
the following:
ph
These functions build a command in the draw buffer to draw a
beveled box. This box is used for the outlines of buttons
and panes.
PgDrawBevelBox() and PgDrawIBevelBox() work on the current
draw context, while you can specify the draw context for PgDrawBevelBoxCx()
and PgDrawIBevelBoxCx().
|
For PgDrawBevelBox() and PgDrawBevelBoxCx(),
the width parameter must be ≤ 15. |
When you increase the thickness, the lines grow toward the
middle of the beveled box. The maximum width is given by
Pg_BEVEL_MAX.
|
PgDrawBevelBox() and PgDrawBevelBoxCx() require a
pointer to a
PhRect_t
structure,
whereas PgDrawIBevelBox() and PgDrawIBevelBoxCx() take
individual arguments. |
- 0
- Success.
- -1
- The draw buffer is too small to hold the current draw state and
the draw command.
The following example:
DrawBevelBox() {
PhRect_t r = { 8, 8, 152, 112 };
PgSetFillColor( Pg_GREY );
PgSetStrokeColor( Pg_WHITE );
PgDrawBevelBox( &r, Pg_DGREY, 4,
Pg_DRAW_FILL_STROKE );
}
