problem while resizing mainwindow.

[phillip_Qt]

in my main window i've 5 lables in a horaizenatllayout. all lable sizepolicy are setting to Prefered.
in my ctor i did like

ui->horizontalLayout->setSizeConstraint(QLayout::SetDefaultConstraint);

ui->horizontalLayout->setSizeConstraint(QLayout::SetDefaultConstraint);

To copy to clipboard, switch view to plain text mode 

But the lables size are not resizing with the main window.
I've attched the ui. plz help me how to solve it. Thank u all.

You have forgot to add a main layout of the dialog, I corrected that. Please see the attched UI file.

Its easy, just right the widget/dialog/mainWindow (what ever you are designing using designer) and select any layout from submenu or use keyboard shortcuts.

You should add the main lay out at the last of your design.
Steps:
1. Create an empty dialog.
2. Add few widgets to it by dragging and dropping.
3. Add those widgets in some layout, lets say in grid layout.
4. At last, right click on dialog and select a layout. This layout will be the main layout of the dialog and should be added at last only.
Please clean your hands on Qt-Designer, do some more practice, its a great tool.
