Hello again,
this post is related to my previous post. As I tried to setup a
parent-hierarchy among my widgets at one point the JVM crashed. I was able to
reproduce and to narrow the problem. Below is my short example program. Even
though I do admit that it makes little sense to make a widget parent of two
different layouts I didn't come across a good explanation for the crash of the
program.
Is this a known issue? Does anyone know more about this?
Cheers, Curt
public class ErrorExample extends QWidget{
public static void main(String[] args) {
QApplication.initialize(args);
ErrorExample testErrorExample = new ErrorExample(null);
testErrorExample.show();
QApplication.exec();
}
public ErrorExample(QWidget parent){
super(parent);
QLayout layout = new QHBoxLayout(this);
QLabel label = new QLabel("Hello World", this);
layout.addWidget(label);
QLayout crashLayout = new QVBoxLayout();
crashLayout.setParent(this);
QLabel labelCrash = new QLabel("Bam!", this);
crashLayout.addWidget(labelCrash); // this line
causes the crash
}
}
