iphone - how to change the UIBarButtonItem size when rotate from the portrait to landscape? -


i add 1 uisegmentedcontrol navigation bar. when view loaded in portrait, frame seems right. when rotate landscape, uibarbuttonitem becomes larger. if rotate portrait again, still remain larger one.

some code snippet here:

#define segment_width   100.0 #define segment_height  32.0  cgrect segmentedcontrolrect = cgrectmake(0, 0, segment_width, segment_height); segmentedcontrol = [[uisegmentedcontrol alloc] initwithframe:segmentedcontrolrect]; segmentedcontrol.momentary = no; segmentedcontrol.segmentedcontrolstyle = uisegmentedcontrolstylebordered; [segmentedcontrol addtarget:self action:@selector(tabbuttonpressed:) forcontrolevents:uicontroleventvaluechanged]; uibarbuttonitem *segmentbarbtn = [[uibarbuttonitem alloc] initwithcustomview:segmentedcontrol];  self.navigationitem.rightbarbuttonitem = segmentbarbtn;

some screenshots follows:

  1. loaded portrait mode. enter image description here

  2. rotate landscape mode. enter image description here

  3. rotate portrait mode. enter image description here

any suggestions appreciated.

do not use bordered style in navigation bar! use uisegmentedcontrolstylebar. that's it's for.

also, not set size (frame) of segmented control. create alloc-init , allow use own intrinsic sizing rules (sizetofit).

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...
