android - Dynamically created button not fill the parent -


i creating table row dynamically in android , creating button in row. rendering fine created button fills parent, i.e. occupies full width of parent row. want fixed width array i.e. 150px.

my code

tablerow rows = new tablerow(this); tablelayout.layoutparams tablerowparamss=      new tablelayout.layoutparams      (tablelayout.layoutparams.fill_parent,tablelayout.layoutparams.wrap_content);       rows.setbackgroundcolor(color.parsecolor("#62b0ff"));      tablerowparamss.setmargins(0, 0, 0, 40);      rows.setlayoutparams(tablerowparamss);       button ib = new button(this);      //ib.setbackgroundresource(r.drawable.accept);      final float scale = getresources().getdisplaymetrics().density;      int heightdp = (int) (33 * scale + 0.5f);      int widthdp = (int) (60 * scale + 0.5f);       viewgroup.layoutparams blp = new viewgroup.layoutparams(widthdp,heightdp);       rows.addview(ib);       table.addview(rows);

how can make button width fixed 150px , align right side of row?

        import tablerowparam       //  import android.widget.tablerow.layoutparams;              @override   public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.text);              tablelayout table = (tablelayout) findviewbyid(r.id.tablelayout1);      tablerow rows = new tablerow(this);     tablelayout.layoutparams tablerowparamss=             new tablelayout.layoutparams                  (tablelayout.layoutparams.fill_parent,tablelayout.layoutparams.wrap_content);      rows.setbackgroundcolor(color.parsecolor("#62b0ff"));     tablerowparamss.setmargins(0, 0, 0, 40);     rows.setlayoutparams(tablerowparamss);      button ib = new button(this);     //ib.setbackgroundresource(r.drawable.accept);             // import android.widget.tablerow.layoutparams;      layoutparams rowparam = new layoutparams(150, layoutparams.wrap_content);      ib.setlayoutparams(rowparam);       rows.addview(ib);       table.addview(rows);   }     <?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"   android:layout_width="match_parent"   android:layout_height="match_parent"   android:gravity="center"   android:orientation="vertical" >      <tablelayout        android:id="@+id/tablelayout1"        android:layout_width="match_parent"        android:layout_height="wrap_content" >      </tablelayout>  </linearlayout>

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...
