java - Coloring JTable row dynamicaly, row selection issue on moving row -


i facing issue jtable.

i doing is: moving table rows dynamically , changing color of rows dynamically. facing following issues:

  1. with moving rows, row selection not moving. so, problem is, user select row , something, meanwhile rows move , selected row other, , user operation getting performed on other row desired row.
  2. some time part row (few columns) getting changed color, time whole row getting colored.

so, want whole row colored dynamically, , row selection should move row moves.

somehow managed update color of whole row,

but still have issue of row selection.

below code:

                    if (i == 0) {                         jc.setbackground(color.orange);                     } else if (i == 1 || == 2) {                         jc.setbackground(color.yellow);                     } else if (i == 3) {                         jc.setbackground(color.green);

in code, when select row, after movements in rows, selected row other, i.e. row selection not moving row moves.

please me on this.

i resolved issue of coloring rows, overridding setvalueat method of defaulttablemodel. overridden method is:

@override public void setvalueat(object avalue, int row, int column) {     vector rowvector = (vector)datavector.elementat(row);     rowvector.setelementat(avalue, column);     // update whole row instead of single cell     firetablerowsupdated(row, row); }

the issue may due multiple threads doing heavily work, , edt may not getting time update whole row. setting value setvalueat method of defaulttablemodel, column coloring sure due fire of cell update event.

but still have issue of selection not moving row moves in table.

opening new thread row selection issue.

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

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).
