html - selectOneListBox with size 1 appears as drop down menu -


i using h:selectonelistbox dynamically add data in it. empty. every time user presses on "add" button, entry added in list box.

i have specified particular height of list box. issue appearance of listbox when has 1 entry. appears drop down menu of specified height rather list box. if has more 1 entry, looks fine.

need know, if there way can control appearance of selectonelistbox when size 1. in below code, assume backingbean.names return 1 select item.

<div style="height: 400px"> <h:selectonelistbox id="names" style="width:100%; height:100%; "    value="#{backingbean.selectedname}"> <f:selectitems value="#{backingbean.names}" /> </h:selectonelistbox> </div>

you need explicitly specify size 2 or larger, otherwise indeed default size of available select items.

<c:set var="size" value="#{fn:length(backingbean.names)}" /> ... <h:selectonelistbox ... size="#{size gt 1 ? size : 2}">

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
