java - How to get horizontal scroll in JTable -


i have 2 issue need ask, 1st how horizontal scroll jtable, shrink columns not readable @ all. have 20 columns show in table.

2nd, how adjust table height width maximum screen size.

my current code is

container cp = getcontentpane();              connectiondb con = new connectiondb();             tablemodel = con.getrecord(default_query);      table = new jtable(tablemodel);     table.setpreferredscrollableviewportsize(new dimension(900, 500));      table.setfont(new font("tahoma", font.plain, 12));     scrollpane = new jscrollpane(table);      centerpanel.add(scrollpane, borderlayout.center);     centerpanel.setborder(borderfactory.createtitledborder("books:"));     cp.add("center", centerpanel);

kindly me in it, in advance.

to prevent columns resized scrollpane size can disable auto resize:

table.setautoresizemode(jtable.auto_resize_off);

adding scrollpane center of borderlayout should set maximum size screen size, because jframe can't become bigger.

to set size of scrollpanes viewport screen size can use awt toolkit.

table.setpreferredscrollableviewportsize(toolkit.getdefaulttoolkit().getscreensize());

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
