Layout automatically adjusting the space dynamically

[nikhilqt]

If widget is managed by a layout then you are not directly responsible for size changes of this widget, so you short code snippet suggests bad design or bug in your code. Describe problem with more details: what is changing that should cause resizing? what is (or isn't) in the layout? Expected outcome? How you code looks like (maybe you did some mistakes)?

The code and the layout everything is working fine. There is no point in bad design or buggy code. Here i want to enter email address, the lineedit should change its width depending on the user entry into the field. So the above code/slot only specifies to increase the lineedit width dynamically.
Expected outcome: 1) increase in the lineedit width(this is happening) 2) Dynamically layout has to adjust the size of the other widgets present in that layout(Not Happening and i want to fix this)

If your setGeometry() call has any visible effect then the widget is not managed by a layout.

oh! Thanks for info. That's what i need. yes, there will be increase in the width of the lineedit and layout has to adjust to size of the other widgets present in it. Then how to achieve it ?

You change the sizeHint or the minimumWidth of the line edit.

Don't forget to do something sane when the user's GMail account is I_am_froody_dude_that_always_knows_where_his_towel _is@gmail.com and you have completely crowded out the other widgets in the layout.
