XFillRectangle(display, d, gc, x, y, width, height)
Display *display;
Drawable d;
GC gc;
int x, y;
unsigned int width, height;
| display | Specifies the connection to the X server. |
| d | Specifies the drawable. |
| gc | Specifies the GC. |
| x y | Specify the x and y coordinates, which are relative to the origin of the drawable and specify the upper-left corner of the rectangle. |
| width height | Specify the width and height, which are the dimensions of the rectangle to be filled. |
[x,y] [x+width,y] [x+width,y+height] [x,y+height]
The function uses the x and y coordinates, width and height dimensions, and GC you specify.
For any given rectangle, XFillRectangle() does not draw a pixel more than once. If rectangles intersect, the intersecting pixels are drawn multiple times.
The function uses these GC components: function, plane-mask, fill-style, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask. They also use these GC mode-dependent components: foreground, background, tile, stipple, tile-stipple-x-origin, and tile-stipple-y-origin.
XFillRectangle() can generate BadDrawable , BadGC , and BadMatch errors.
| BadDrawable | A value for a Drawable argument does not name a defined Window or Pixmap. |
| BadGC | A value for a GContext argument does not name a defined GContext. |
| BadMatch | An InputOnly window is used as a Drawable. |
| BadMatch | Some argument or pair of arguments has the correct type and range but fails to match in some other way required by the request. |
