How to resize QWidget to fit its contents?

[lachdanan]

Hi,

Basically I have a QTableWidget inside a QVBoxLayout. I set everything so that my table widget resizes to fit the contents. This is good, but I can't get my QWidget that hosts this table widget to resize itself to show everything.

I checked tablewidget.size() but the size is not the correct size, because if I use the same size for my QWidget, the table is cropped, i.e. I can't see it fully.

How can I achieve this?

Thanks in advance.

try tableWidget->setSizeAdjustPolicy(QAbstractScrollArea::AdjustToContents);

@VRonin Thanks a lot, you are right it works :) I have another issue about the row heights, I am trying to resize them but they don't seem to get smaller in height than this:

I am doing it like this:
```
hh = tableWidget.horizontalHeader()
hh.setSectionResizeMode(QtWidgets.QHeaderView.ResizeToContents)

    hh.setFixedHeight(50)
    #hh.setStretchLastSection(True)

    vh = tableWidget.verticalHeader()
    vh.setSectionResizeMode(QtWidgets.QHeaderView.Fixed)
    vh.setDefaultSectionSize(1)

I don't understand why row heights refuse to get smaller.

Hi
There is
vh.setMinimumSectionSize(xx);
and setDefaultSectionSize won't go under that value
so you must lower that first to go really low.

@mrjj said in How to resize QWidget to fit its contents?:

setMinimumSectionSize

Thanks a lot I just tried that but no luck, and if I remove default section size function call, then they get larger:

vh.setDefaultSectionSize(1)
vh.setMinimumSectionSize(1)

This still looks same size for example.

When I used this it worked: vh.setSectionResizeMode(QtWidgets.QHeaderView.Stretch)
