How to adjust widgets automatically to screen resolutions
I am very newbie to Qt. I have developed a Qt GUI aplication for Desktops. In my application i have used some buttons and textboxes.
The problem is that when i deploy it on machine of different resolution the Widgets are going here and there. I dontwant to create widgets through code , i just want to drag from menu and use it .
Plz tell me how i can make them autoadjustable to diffrent screen resolution.
Thans in advnce

please tll me how to cahnge these properties of widgets.
Thanking u in advance
bq. All QWidget subclasses can use layouts to manage their children. The QWidget::setLayout() function applies a layout to a widget. When a layout is set on a widget in this way, it takes charge of the following tasks:
- Positioning of child widgets.
- Sensible default sizes for windows.
- Sensible minimum sizes for windows.
- Resize handling.
- Automatic updates when contents change:
- Font size, text or other contents of child widgets.
- Hiding or showing a child widget.
- Removal of child widgets.
So, you can let Layout Manger do that, or you should override events of your main widget and change needed properties dynamically... Like "resizeEvent":http://doc.qt.digia.com/qt/qwidget.html#resizeEvent If you can show us an example of what you are doing and how the properties should be changed, maybe you will get more exact advice...
There are 4 ready-made layouts : QVBoxLayout, QHBoxLayout, QGridLayout and QFormLayout. All of them inherit QLayout.
If any of them doesn't fit your application you can subclass QLayout and create a custom layout :)
