type cast from int to QString

spoody_goon · 05-19-2005, 06:08 PM

I am a windows programmer looking to get started in Linux. I have chosen kdevelop and qt to design and code. How big is the learning curve when moving from a msdn enviroment to a Linux enviroment?

I could use any resourses for kdevelop and qt that anyone may have, I have a few already but you can never have enough.

Now for the big question I am goofing with a turorial and I need to know how to type case from an int to a QString?

Code:

#include <qlineedit.h>
#include <qcombobox.h>
#include <qmultilineedit.h>
#include "sigcreate.h"

SigCreate::SigCreate(QWidget* parent, const char* name, WFlags fl)
    : Form1(parent,name,fl)
{}

SigCreate::~SigCreate()
{}

/*$SPECIALIZATION$*/
void SigCreate::slotCreateSig()
{
	QString TestString;
	int StringLength;
	
	TestString = nameBox->text();
	StringLength = TestString.length();
	
	sigBox->setText(TestString);
	sigBox->append("\n--");
	// sigBox->append(Cstr(StringLenght));
}

Does my windoz experiance hang out?

Got it if anyone else wants to know use QVariant like so:

Code:

#include <qlineedit.h>
#include <qcombobox.h>
#include <qmultilineedit.h>
// ADDED THIS
#include <qvariant.h>
#include "sigcreate.h"

SigCreate::SigCreate(QWidget* parent, const char* name, WFlags fl)
    : Form1(parent,name,fl)
{}

SigCreate::~SigCreate()
{}

/*$SPECIALIZATION$*/
void SigCreate::slotCreateSig()
{
	QString TestString;
       // ADDED THIS 
	QVariant StringLength;
	QString CastedString;
	
	TestString = nameBox->text();
	StringLength = TestString.length();
	CastedString = StringLength.toString();
	
	sigBox->setText(TestString);
	sigBox->append("\n--");
	sigBox->append(CastedString);
	
	
}

Whaaat? Just use the static function QString::number(yourInteger), which also works with doubles / longs etc....
