(Solved) QLCDNumber simple problem

[poporacer]

I have a widget with a QLCDNumber that I can't get to display anything. The form was created using Creator and in the constructor for the form, I want to initialize the number. I have read throught the forum and documentation and it should work...not sure why. From what I read, I think that QLCDNumber can take a double or string value. I tried several variations just to get it to work and none of them worked.

here is the code

Timer::Timer(QWidget *parent) :
QWidget(parent),
ui(new Ui::Timer)
{
ui->setupUi(this);
ui->lcdDisplay->display(2345);
//ui->lcdDisplay->display("2345");
//ui->lcdDisplay->display(1234.5);
}
I was looking at this too long...I had a function call later on in the code for initializing everything and it set the number to 0...

Can you explain what you mean by "can't get to display anything"? You cannot see the QLCDNumber widget at all (it has a frame that is always there), or the number is visible but 0, or something else?

This small program works fine here:


#include <QtGui>
#include <QDebug>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);

QLCDNumber lcd;
lcd.display(2345);
// These work too
// lcd.display(2345.0);
// lcd.display("2345");
lcd.show();

return app.exec();
}



Edit: OK, you found the problem. Ignore this.
