    text
    <p>I have a widget to insert that looks like this</p> <pre><code>+--------------------+ | +-------++-------+ | | | || | | | | || | | | | || Label | | | | Label || Label | | | | || | | | | || | | | +-------++-------+ | +--------------------+ </code></pre> <p>A QWidget element containing two QVBoxLayouts, each containing one or more QLabels.<br>This Widget is going to be inserted in a Vertical Layout that has a stretch cell, so all the widgets of this kind will go to the top and shrink to the smaller height possible.</p> <p>Resulting in something like this.</p> <pre><code>______________________ ← Layout boundary +--------------------+ | +-------++-------+ | | | || Label | | | | Label || Label | | ← Widget shrunk to the smallest | +-------++-------+ | +--------------------+ ______________________ ← Layout boundary ↑ | | ← Spacer | ↓ ______________________ ← Layout boundary </code></pre> <p>But before doing this insert, I want to know the size that the widget would have in the inserted layout. Maybe the minimum size allowed by its internal layout. Not sure how to call it.</p> <p>I have tried already many approaches like inserting the widget in an alternate invisible layout so I can retrieve its height when inserted, which should be the same that the widget would take when inserted in my definitive layout.</p> <p>But for some reason I always get 480 or 478 when the widget is at most 50px height when pressed vertically. So I am totally lost.</p> <p>I have to do this because I need the widget to animate when inserting, and I need to know the height it will take for me to animate from height 1 to it.</p> <p>How can I do this?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
