Problem with displaying a QPixmap on a QImage

Hello everyone,

i've written the following code:

Code:

---

img = new QImage("images/01_greyscale.png");
	QLabel *text1 = new QLabel(tr("..."));
	img_greyscale->setPixmap(QPixmap::fromImage(*img));
	img_greyscale->show();
 
	QVBoxLayout *leftLayout = new QVBoxLayout;
	leftLayout->addWidget(text1);
 
	setLayout(leftLayout);
	setWindowTitle(tr("Test"));

---

"img_greyscale" is defined in the header-file.
When starting the program with the "img_greyscale->setPixmap" line no Window pops up, nothing happens at all, not even an error is thrown. But i can't terminate the program so there must be a problem with this line.
What do i do wrong?

The "images" folder lies in the source-folder. The png-image weights only 8kb.


Thanks for your help.

Where do you define img_greyscale? Are you sure img_greyscale is not 0 at this state?

When you say "defined in the header-file", do you mean it is declared? Is it initialized as well?

I am guessing img_greyscale has not been initialized (new QLabel) ?

Damn, thank you very much!
I just didn't initialized the QLabel. Stupid me.. :confused:
