Problem with spinbox?

[pratik041]

I am using three spinbox in my program and the problem is that while running the program the cursor always remain in one of the spinbox but i want that in initial condition the cursor position should not be in the spin box.

[fluca1978]

Does it giving the focus to another component that is not the spin boxes solve the problem?

[pratik041]

actually other widget are not getting keyboard focus . While pressing tab the focus going to next spinbox.

Not sure why this behavior is wrong for you. Could you please post an example to help us understand the problem?

[pratik041]

I have one code where it is working fine but after some modification in the same code it is not working. can you give me your mail id so that i can post you the code.

Please keep the discussion on the -list- forum. That way, we all can learn from it.

[pratik041]

but i can't post the code here because it is too long to accommodate here

[andre]

Please cut it down to a postable example showing the problem then. You will need to do that anyway; you can not expect another to dig through hundreds of lines of irrelevant code to try to help you find your problem. Debugging is your task, not ours.

This is the code
@main.cpp
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;

int min = 0;
int max = 100;
QPixmap pixmap(":/simple_track_bar.png");
QPixmap pixmap1(":/simple_track_thumb.png");
QRect rect(50,60,4,118);

MBSlider *mb3 = new MBSlider(min, max, pixmap, pixmap1,rect,false,&w);
QSpinBox *spinBox3 = new QSpinBox;
spinBox3->setRange(0, 100);

QObject::connect(spinBox3, SIGNAL(valueChanged(int)),mb3, SLOT(setValue2(int)));
QObject::connect(mb3, SIGNAL(sliderMoved(int)),spinBox3, SLOT(setValue(int)));

Not sure I'm getting the problem, but does not
@mb3->setFocus();@

solve it? You are asking, if I get it right, that the spin box does not have the focus initially.
Moreover, the problem you are trying to face here is the cause of "another problem you posted":http://developer.qt.nokia.com/forums/viewthread/11629/. You should try to solve one per time (in my opinion).

ya i will try that
