<Solved>to get current time to display in a text edit box.

[cdbean04]

I am trying to have a text edit box display a time stamp with the current time on the push of a button called start.. Also I want to put it in a loop so that it will create a running list of current times. Here is the code I have so far, clearly it is wrong.
code/
#include "heatmode.h"
#include "ui_heatmode.h"
#include "wiringPi.h"
#include <QTime>
#include <QTextEdit>

heatmode::heatmode(QWidget *parent) :
QWidget(parent),
ui(new Ui::heatmode)
{
ui->setupUi(this);
}

heatmode::~heatmode()
{
delete ui;
}

void heatmode::on_startButtonHeatMode_clicked()
{
QTime time = QTime::currentTime();

//display time every 5 seconds
ui->tempTimeBoxHeatMode->QTextEdit::setText(time);

}
/code

I have edited out other parts of code that are not relevant to the time.
Thanks for your help.

Hi,

QTime::toString is what you are looking for

[cdbean04]

Thanks SGaist I got the current time to display, now I am having an issue getting it to keep populating. I am trying to get it to display the current time every 5 seconds, with it keeping a running list.
ex.
currentTime
currentTime 5 seconds later
currentTime 5 seconds after that
currentTime etc.
But it is not working, I have tried several different types of loops to try and get the desired results, to no avail. Here is my current code.

void noheatmode::on_timeButton_clicked()
{
//Get Current time and convert it to a string

int i = 30;
do
{
QTime time = QTime::currentTime();
QString sTime = time.toString("hh:mm:mm");
ui->tempTimeNoHeatMode->append(sTime);
delay(5000);

 i--;
}while(i>0);

}

I am trying to display it in a text edit box. Any ideas?

You are blocking the main thread with your loop. Take a look at QTimer, there's even a clock example you can find in Qt's examples

After glancing over QTime I am not sure if it is what I am looking for. It is clearly a timer, what I ultimately am doing is taking the temperature of a heating device and outputting its temperature with a time stamp on it. I plan to check the temperature every few seconds, 5 seconds was just an arbitrary time i used. I do not have the heating device I am measuring off yet so I was just trying to get the time display working so later I can just add to temperature out put to it.

No QTime, QTimer. If all you want to do is get a reading every five second, just connect the timeout signal of a QTimer to a slot that will simulate the reading and you're good to go, aren't you ?

Yep it works.
Thanks again, you always come through SGaist.
