Summary: NSView redisplay doesn't update display when selection
changes
Product: WebKit
Version: 522+ (nightly)
Platform: Macintosh
OS/Version: Mac OS X 10.4
Status: UNCONFIRMED
Severity: Normal
Priority: P2
Component: WebKit Misc.
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: com-webkit at sabi.net
I'm trying to flash the selected text synchronously, but asking the NSView to
redisplay doesn't draw anything after I change the selection. This code works
fine in released versions of Safari 2 (419.3).
WebHTMLView *view;
[...]
NSRect selectionRect = [view selectionRect];
for (i = 0 ; i < textBlinkCount ; i++) {
[view deselectAll];
[view setNeedsDisplayInRect: selectionRect];
[view display];
usleep(60000);
[[view _bridge] selectNSRange: selectedRange];
[view setNeedsDisplayInRect: selectionRect];
[view display];
usleep(60000);
}
I asked about this on #webkit and Darin suggested using [[view window]
displayIfNeeded], which behaved identically to the above code (works in 419.3,
not in nightly).
