Using K Objects in Qt project

[dec0ding]

Hi,

all projects I have been working so far has been created using pure Qt code. Now I see some interesting K classes and want to use them. I put them in my test application (using KUrl object) and at linking time I get this:

obj/form1.o(.text+0x42a): In function Form1::Form1[not-in-charge](QWidget*, char const*, bool, unsigned)':
: undefined reference to KURLRequester::KURLRequester[in-charge](QWidget*, char const*)'

I put LIBS += -L/opt/kde/lib in my pro file but no help

You have to link with proper kde libs (LIBS += -lkdeui -lkdecore and/or other). And use KApplication instead of QApplication. Generally this is called KDE programming

If you need to use KDE Widget I suggest you to make a KDE Application.
In this way you can use complete KDE framework utilities.

Ok but I have written 1000 code so I need to use some KDE Widgets now, that is why I asked...

Wysota: I tryed -lkdeui and -lkdecore but both show this error:

usr/lib/gcc-lib/i486-slackware-linux/3.3.6/../../../../i486-slackware-linux/bin/ld: cannot find -lkdeui
collect2: ld returned 1 exit status
make: *** [learn] Error 1

Thanks

You need to provide a path to look for those libs (using -Lsome_directory)

[dec0ding]

Ok solved...
I put the project in KDevelop and now working from there

Thanks both

I put in my *.pro file this:

LIBS += -L/opt/kde/lib/

then, where do I put -lkdeui, -lkdecore?e

In the same place:

LIBS += -L/opt/kde/lib/ -lkdeui -lkdecore

You should take in consideration, that by using kde libs, you are loosing one of Qt best fetures - its portability.
So if you want to write applications that will run on kde explicitly, then ok, but if not, better create your own classes in Qt that do the same as the KDE calsses that you use do.

In the same place:

LIBS += -L/opt/kde/lib/ -lkdeui -lkdecore

Thanks

theLSB: well u said good thing that I never thought of...maybe I will go on with pure Qt ...
