when i try to build it I get a linker error:

Source code

#include "tst.h"

#include <qlabel.h>

#include <kmainwindow.h>
#include <klocale.h>

tst::tst()
    : KMainWindow( 0, "tst" )
{
    // set the shell's ui resource file
    setXMLFile("tstui.rc");
	KFileTreeView * tree = new KFileTreeView(this,"name");
	KCombiView(this,"name");
	KColorDialog * la = new KColorDialog(this,"name");
	la->show();
}

tst::~tst()
{
}

the output(using kdevelop):

I think it is kind of strange that I can link against KColorDialog, but not against any in KIO. Maybe one can help me fiddling it out.

You need -lkdeio or something like that (forgot the exact string) for linking with KIO. I cant check it at work here. If you are using this from KDevelop, then you can right click on your target on the right, and in the properties add to the libraries KIO. I'll be able to double check the details when I get home. But it's either -lkio, or -lkdeio, or something similar.

printf("%10.2f", x);
C++:
cout << setw(10) << setprecision(2) << showpoint << x;
Java:
java.text.NumberFormat formatter = java.text.NumberFormat.getNumberInstance();
formatter.setMinimumFractionDigits(2);
formatter.setMaximumFractionDigits(2);
String s = formatter.format(x);
for (int i = s.length(); i < 10; i++) System.out.print(' ');
System.out.print(s);

Just in case, if you are doing it from KDevelop in the make target options, under the Libraries tag in "Link libraries outside the project (LDADD)", you can add $(LIB_KIO).
