I have a couple of problems with GC calls, and I'm curious if I'm doing something wrong, or if other people have these problems as well (and they are actually bugs). First, when I use XSetLineAttributes to change the line_style, it doesn't always work. If I change something else in the GC along with the line style (such as the width or dash list), then the call seems to work fine. But if I set the line style alone, no changes are evident. Specifically, I make calls: XSetLineAttributes(display, gc, x_width, LineOnOffDash, x_cap_style, x_join_style); XSetDashes(display, gc, 0, new_dash_list, new_num_dash); . . and I get the line style I expect. Then I make the call: XSetLineAttributes(display, gc, x_width, LineSolid, x_cap_style, x_join_style); and the line style is still dashed, with the previously specified characteristics. However, if instead the second call to XSetLineAttributes is: XSetLineAttributes(display, gc, new_width, LineSolid, x_cap_style, x_join_style); then I get the expected solid line, with the new width value. Second problem - I can't seem to get the join style to be set to JoinRound. I make the call: XSetLineAttributes(display, gc, width, style, cap_style, JoinRound); and when I draw a rectangle using XDrawRectangle or XFillRectangle, I get square-cornered rectangles. I don't know if this problem is related to the above problem, but no matter what the width or dash style of the line, I seem to get no reaction to the join style setting. Is XSetLineAttributes the wrong function to use? I'm working with X.V11R2 on a Sun 3/260 running SunOS 3.2. Any working examples or explanations of what I may be doing wrong would be much appreciated. Thanks, ~ penny bauersfeld.wbst@xerox.com
