<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This cause an invisible main window in KCalc, due to a <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">setFixedSize(minimumSize())</code> call.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This (new?) behavior is documented in the <a href="http://doc.qt.io/qt-5/qwidget.html#minimumSize-prop" style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">QWidget api</a>, so it doesn't look like a bug in Qt.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The proper way to set a fixed size (based on the actual content) is to use <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">QLayout::setSizeConstraint()</code>, as suggested by the <a href="http://doc.qt.io/qt-5/qwidget.html#setFixedSize" style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">documentation</a> of <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">setFixedSize()</code> itself.</p></pre>
