I want to resize a dialog to the width of a QTableView inside of it....

[jdent]

I tried this:

    QSize sizeOfTableView = tableView->size();
    QSize sizeOfWindow = this->size();
    resize(sizeOfTableView.width(), sizeOfWindow.height());

it does not work as expected!

@jdent Behaviour may depend on where/when you call this code.

Show us a screenshot of what you get.

As I said earlier, the sizes of the inner widgets are valid once the dialog is shown.

@mpergand ok, how can I capture the moment a dialog is shown??

In MFC there was a OnInitDialog() method.... nothing similar here? There must be a signal to trap...
