No error is Their but The emulator is unable to run this program....
When i click the ".exe" for this program no action is being taken place in the emulator

Hi,

Can you explain what you meant by:

layout.exe is unable to build

Have you tried using the debugger to see if the application starts and reaches a breakpoint at the first line?

Hi mind_Freak,
I think there is nothing wrong with your Qt installation but only a few syntax error is there. I had corrected that,just replace the few lines given below.

QSpinBox *spinBox=new QSpinBox;
QSlider *slider=new QSlider(Qt::Horizontal);
spinBox->setRange(0,135);
slider->setRange(0,130);
QObject::connect(spinBox,SIGNAL(valueChanged(int)),slider,SLOT(setvalue(int)));
QObject::connect(slider,SIGNAL(valueChanged(int)),spinBox,SLOT(setvalue(int)));
spinBox->setValue(35);

Please let us know that this works for you or some errors are there...?

Hope this helps you.

Hi,

Indeed, there were syntax errors in your code with incorrect bracketing - this WILL have caused the build to fail. The icon in the emulator would have been from a previous version that did build and it didn't launch because it hadn't been successfully rebuilt. You need to read the console output from the builds to be sure the build is successful and find errors, otherwise this will happen again.

Hope that explains it.

After pressing the "Press Me" button the "hello" button should get disable,but its not working...
Plz get me to a proper way and let me know the errors...

#include <QtGui>
#include <QApplication>
#include<QPushButton>
#include<QHBoxLayout>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QWidget *window = new QWidget();
QPushButton* but1=new QPushButton("Press Me");
QPushButton* but2=new QPushButton("Hello");
QHBoxLayout* layout=new QHBoxLayout;

layout->addWidget(but1);
layout->addWidget(but2);

window->setLayout(layout);
window->show();
QObject::connect(but1,SIGNAL(clicked()),but2,SLOT(setEnable(false)));
return a.exec();
}

Hi Mind_Freak,
please replace the following line in your code

QOBJECT::connect(but1,signal(clicked()),but2,slot(setDisabled(1)));

Hope it helps you.

Hi mind freak

It would be better to start the new question with new thread.
