<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">I've asked a question kind of like this before, but this time, I've made sure I have a newer version (1.4.2). I'm doing the following sequence (in pseudocode):<DIV><BR class="khtml-block-placeholder"></DIV><DIV>nsGC = [NSGraphicsContext graphicsContextWithWindow: anNSWindow];</DIV><DIV>cgRef = [nsGC graphicsPort];</DIV><DIV>surface = cairo_quartz_surface_create_for_cg_context(cgRef, 300, 300);</DIV><DIV>cr = cairo_create(surface);</DIV><DIV>cairo_set_source_rgb(cr, 0.0, 0.0, 1.0);</DIV><DIV>cairo_paint(cr);</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Is this the sequence other's use for drawing on quartz windows? Because it doesn't update. If I drag the window, it seems to flush the GC. Do I have to follow every cairo paint() call with some sort of sync to the quartz APIs? Or is there a flag I can set that will make it happen right away?</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>TIA</DIV><DIV><BR><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 18px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><DIV>--</DIV><DIV>Travis Griggs</DIV><DIV>Objologist</DIV><DIV>Time and Countertops.
