Nsview not updating

Rated 3.95/5 based on 958 customer reviews

Retina support can add a new dimension to this headache when you’re dealing with pixel coordinates.Say you have a flipped NSView with an origin of 0,0 and dimensions of 1440 x 900 (e.g it covers the entire Retina screen in points.) Y coordinates on the screen can range in value from 0.0 to 899.5.What I have just noticed now though, is that I don't think Finder is freezing, but rather the display is not updating.I think this because I can open the Finder while it works, select a file, wait for it to freeze - click some else in the window to confirm - click on a file, then press "return".As I alluded to on Episode 14 of The Talk Show, this update was harder than most.The 68k to Power PC, Carbon to Cocoa, and Power PC to Intel transitions were no walk in the park, but this update really kicked my butt.But the shortcut links were still in Finder on the left.

To deal with the first problem, I used an NSEvent category that clamps events so the arrow keys can home in on the destination pixel.There are many cases where x Scope has to align to a pixel boundary.I found myself using this pattern many times throughout NSBezier Path *line = [NSBezier Path bezier Path]; [line set Line Width:pixel Width]; [line move To Point: NSMake Point(point.x point Offset, 0.0); [line line To Point: NSMake Point(point.x point Offset, 100.0); [line stroke]; , but in my experience it’s much more common to need aligned NSPoint values when you’re doing custom drawing.Edit: Console output every time I click on the window 7/10/2014 .163 pm Finder[777]: -[__NSCFString has Prefix:]: nil argument 7/10/2014 .166 pm Finder[777]: ( 0 Core Foundation 0x00007fff90e6a25c __exception Preprocess 172 1 libobjc.A.dylib 0x00007fff8f768e75 objc_exception_throw 43 2 Core Foundation 0x00007fff90e6a10c [NSException raise:format:] 204 3 Core Foundation 0x00007fff90d8332a -[__NSCFString has Prefix:] 90 4 Finder Ext 0x0000000101312693 v Log Debug 617 5 Finder 0x0000000100cd8fcc Finder 1073100 6 Finder 0x0000000100cd8f29 Finder 1072937 7 Finder 0x0000000100cd8407 Finder 1070087 8 Finder 0x0000000100cd7d5f Finder 1068383 9 Finder 0x0000000100cd7c27 Finder 1068071 10 App Kit 0x00007fff8b147468 -[NSControl draw Rect:] 341 11 Finder 0x0000000100c1c54c Finder 300364 12 App Kit 0x00007fff8b13a04f -[NSView _draw Rect:clip:] 3748 13 App Kit 0x00007fff8b1388c4 -[NSView _recursive Display All Dirty With Lock Focus:vis Rect:] 1799 14 App Kit 0x00007fff8b138ca0 -[NSView _recursive Display All Dirty With Lock Focus:vis Rect:] 2787 15 App Kit 0x00007fff8b138ca0 -[NSView _recursive Display All Dirty With Lock Focus:vis Rect:] 2787 16 App Kit 0x00007fff8b138ca0 -[NSView _recursive Display All Dirty With Lock Focus:vis Rect:] 2787 17 App Kit 0x00007fff8b138ca0 -[NSView _recursive Display All Dirty With Lock Focus:vis Rect:] 2787 18 App Kit 0x00007fff8b136706 -[NSView _recursive Display Rect If Needed Ignoring Opacity:is Visible Rect:rect Is Visible Rect For View:top View:] 841 19 App Kit 0x00007fff8b137bc4 -[NSView _recursive Display Rect If Needed Ignoring Opacity:is Visible Rect:rect Is Visible Rect For View:top View:] 6151 20 App Kit 0x00007fff8b137bc4 -[NSView _recursive Display Rect If Needed Ignoring Opacity:is Visible Rect:rect Is Visible Rect For View:top View:] 6151 21 App Kit 0x00007fff8b137bc4 -[NSView _recursive Display Rect If Needed Ignoring Opacity:is Visible Rect:rect Is Visible Rect For View:top View:] 6151 22 App Kit 0x00007fff8b137bc4 -[NSView _recursive Display Rect If Needed Ignoring Opacity:is Visible Rect:rect Is Visible Rect For View:top View:] 6151 23 App Kit 0x00007fff8b3181e2 -[NSBrowser _recursive Display Rect If Needed Ignoring Opacity:is Visible Rect:rect Is Visible Rect For View:top View:] 80 24 App Kit 0x00007fff8b137bc4 -[NSView _recursive Display Rect If Needed Ignoring Opacity:is Visible Rect:rect Is Visible Rect For View:top View:] 6151 25 App Kit 0x00007fff8b137bc4 -[NSView _recursive Display Rect If Needed Ignoring Opacity:is Visible Rect:rect Is Visible Rect For View:top View:] 6151 26 App Kit 0x00007fff8b137bc4 -[NSView _recursive Display Rect If Needed Ignoring Opacity:is Visible Rect:rect Is Visible Rect For View:top View:] 6151 27 App Kit 0x00007fff8b137bc4 -[NSView _recursive Display Rect If Needed Ignoring Opacity:is Visible Rect:rect Is Visible Rect For View:top View:] 6151 28 App Kit 0x00007fff8b135eb1 -[NSTheme Frame _recursive Display Rect If Needed Ignoring Opacity:is Visible Rect:rect Is Visible Rect For View:top View:] 314 29 App Kit 0x00007fff8b132e9f -[NSView _display Rect Ignoring Opacity:is Visible Rect:rect Is Visible Rect For View:] 2828 30 App Kit 0x00007fff8b1122da -[NSView display If Needed] 1680 31 App Kit 0x00007fff8b17774e _handle Window Needs Display Or Layout Or Update Constraints 884 32 App Kit 0x00007fff8b74d061 __83-[NSWindow _post Window Needs Display Or Layout Or Update Constraints Unless Posting Disabled]_block_invoke1331 46 33 Core Foundation 0x00007fff90d9ad67 __CFRUNLOOP_IS_CALLING_OUT_TO_AN_OBSERVER_CALLBACK_FUNCTION__ 23 34 Core Foundation 0x00007fff90d9acd7 __CFRun Loop Do Observers 391 35 Core Foundation 0x00007fff90d8c3b8 __CFRun Loop Run 776 36 Core Foundation 0x00007fff90d8be75 CFRun Loop Run Specific 309 37 HIToolbox 0x00007fff90a13a0d Run Current Event Loop In Mode 226 38 HIToolbox 0x00007fff90a13685 Receive Next Event Common 173 39 HIToolbox 0x00007fff90a135bc _Block Until Next Event Matching List In Mode With Filter 65 40 App Kit 0x00007fff8afdb24e _DPSNext Event 1434 41 App Kit 0x00007fff8afda89b -[NSApplication next Event Matching Mask:until Date:in Mode:dequeue:] 122 42 App Kit 0x00007fff8afce99c -[NSApplication run] 553 43 App Kit 0x00007fff8afb9783 NSApplication Main 940 44 Finder 0x0000000100bd9730 Finder 26416 45 libdyld.dylib 0x00007fff85c805fd start 1 ) The issue was created because either the Google Drive App or the Dropbox App lost their download directories.
