Hi,
I want to draw poly lines using Gtk+ over DirectFB backend.
The code i am using, is given below.
GdkGCValues values;
values.line_width = 15;
values.line_style = GDK_LINE_ON_OFF_DASH;
values.cap_style = GDK_CAP_ROUND;
values.join_style = GDK_JOIN_BEVEL;
gdk_gc_set_values (GdkGraphDescPool[gdkGraphDesc].gc, &values,
GDK_GC_LINE_WIDTH | GDK_GC_LINE_STYLE | GDK_GC_CAP_STYLE | GDK_GC_JOIN_STYLE);
/*for (i = 0; i < nPoints-1; i++) {
gdk_draw_line (GdkImageDescPool[GdkGraphDescPool[gdkGraphDesc].gid].pixmap,
GdkGraphDescPool[gdkGraphDesc].gc, points[i].x, points[i].y, points[i+1].x,
points[i+1].y);
}*/
gdk_draw_lines(GdkImageDescPool[GdkGraphDescPool[gdkGraphDesc].gid].pixmap,GdkGraphDescPool[gdkGraphDesc].gc,points,
(gint)nPoints);
I am facing problem regarding line attributes.
The line attributes (e.g. line width, line style, cap style, join style) that i
am setting has no effect on output.
For example, line width in the output, is same irrespective of "line_width"
value in the code.
I think the setting the attributes of line is not supported in DirectFB.
Please help me to solve this problem.
Thanks in advance.
