designing in qt3

[wysota]

I don't see how is your issue related to kde custom widgets... All you need to run an external application is QProcess, you don't need any kde related stuff.

But anyway, if you want to use kdeui, you just have to link with it, for example by adding LIBS+=-lkdeui to your .pro file (remember to run qmake afterwards).

you are correct
in veiw of the Qprocess my problem has got very less to do with Kwidgets.

In order to call Qprocess. fn() i will have to do something like this in .ui.h

void  FORM2::openfile()
{
pushbutton->----- / here will the function of Qprocess work
}

void  FORM2::openfile()
{
pushbutton->----- / here will the function of Qprocess work
}

To copy to clipboard, switch view to plain text mode 

and i shall be connecting the pushbutton to the slot openfile()

how do i ensure that form2 class takes functions from Qprocess also.

[wysota]

Just create a QProcess object either as a member of the class or in the slot which makes use of it (be sure it is allocated on heap in the latter case, so that it doesn't go out of scope).

i have now done the following

#include <qprocess.h>
void Form2 :: showimage()
{
        QProcess* proc = new QProcess( this );
        proc->addArgument( "eog  " );
        proc->addArgument("/root/images/dk.jpg"); 
        proc->start();		  
}

#include <qprocess.h>
void Form2 :: showimage()
{
        QProcess* proc = new QProcess( this );
        proc->addArgument( "eog  " );
        proc->addArgument("/root/images/dk.jpg"); 
        proc->start();		  
}

To copy to clipboard, switch view to plain text mode 

// where showimage is a slot connected by pushbutton
i am able to qmake and make also
but when i run
i get the following message
---------------------------------------------------------------------------

i am not able to find ~/.scim/global in the directories even after an extensive search .
please guide me .

[wysota]

But what does it have to do with Qt? The error comes from the external app you start with QProcess...

[deekayt]

but sir
my problem is not still sorted out
infact on he command line "eog filename" works fine
even system ("eog filename" ) works
then why not qprocess
please guide me
thanks in advance

[wysota]

I'm sorry, I don't know this "eog" app, so I won't be able to help you. In general it looks like there is something wrong with your kde installation (or scim). Do you get the same message while running "eog" from the command line?

Anyway you might try what the message suggests -- create ~/.scim/global and set /DefaultConfigModule to kconfig. If you have any doubts here, google is your friend.

BTW. Next time please use the "[code]" tags to format the source code you enter here. The tag is available under the "#" button in the editor toolbar.
