iphone - Swapping views inside a tabview controller -


i have app based on tabbar controller. within view i'd add swipe gesture recognition , swap current view 1 (which not part of tabbarcontroller array). have tried:

- (ibaction)swipeleftdetected:(uigesturerecognizer *)sender { //does not work uiviewcontroller *desiredviewcontroller =[[uiviewcontroller alloc] initwithnibname:@"desiredviewcontroller" bundle:nil]; desiredviewcontroller.modaltransitionstyle = uimodaltransitionstylecrossdissolve; [self presentmodalviewcontroller:desiredviewcontroller animated:yes];  [self.view addsubview:desiredviewcontroller.view]; }

but program crashes. error related segmentedcontrol present in next view absent in current one. views independently work perfectly!

*** terminating app due uncaught exception 'nsunknownkeyexception', reason:'[<uiviewcontroller 0xa355fb0> setvalue:forundefinedkey:]: class not key value coding-compliant key x_segmentedcontrol.'

i don't understand doing wrong.. want swap views rather putting 1 on top of each other. advice please? thanks

the problem not transition.

you loading view controller nib.

a view controller subclassed, (assuming nib configured correctly , have .h , .m implementation file desiredviewcontroller subclass) should init this:

desiredviewcontroller *controllerinstance =[[desiredviewcontroller alloc] initwithnibname:@"desiredviewcontroller" bundle:nil];

the exception because have segmented control inside view controller subclass, xcode trying link control outlet on view controller, outlet doesn't exists (because allocating uiviewcontroller not subclass).

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
