QWidget not resizing on QtDesigner

[wasawi2]

Dear all,

I have two identical projects, one uses QtDesigner to load some widgets and the other loads them directly from code. In both of them i wanted a widget to be resized when the user resizes the window. In the project that does not use QtDesigner that happens perfectly well but in the other identical QtDesigner project it does not resize at all.

I have used the following code in my widget class to make the resize happen:

void LineWidget::resizeEvent(QResizeEvent *)
{
    m_defaultChartView->resize(size());
}

So for some reason the two projects, even if they are identical they do not behave in the same way.

Any idea what might be going on?

you can see the complete code of the project in my last post.

Thank you for any hints.
Best,
w

Why don't you simply use layouts?

@jsulm thank you for answering.

As you can see form the code in my previous post I have used QHBoxLayout both in QtDesigner and from code. The code veersion works as expected but the QtDesigner version does not resize.

Start by placing some breakpoints/debug messages e.g. in your resizeEvent()? Check the value of size().

Not sure why you have to do this resize in code, but maybe. Your LineWidget instance(s) themselves have a layout onto which the chart view is placed?
