    <p>I want a python application that displays a bunch of small portraits and a names below it. Like that: <img src="https://i.stack.imgur.com/iBwoW.png" alt="This is how the application looks like"></p> <p>They should be movable and editable (by double clicking the text).</p> <p>I am using PyQt4 so I figured out, it would be easiest to use a <code>QGraphicsView</code> and a <code>QGraphicsScene</code> for the canvas. So I subclassed a <code>QGraphicsItemGroup</code> like this:</p> <pre><code>from PyQt4 import QtCore, QtGui class Speaker(QtGui.QGraphicsItemGroup): def __init__(self, name, parent=None): QtGui.QGraphicsItemGroup.__init__(self, parent) self.setFlag(QtGui.QGraphicsItem.ItemIsMovable) self.text = QtGui.QGraphicsTextItem(name) self.text.setTextInteractionFlags(QtCore.Qt.TextEditorInteraction) self.addToGroup(self.text) self.portrait = QtGui.QGraphicsPixmapItem(QtGui.QPixmap("portrait.png")) self.portrait.setY(-35) self.addToGroup(self.portrait) def keyPressEvent(self, QKeyEvent): # Forwarding KeyPress events to the text to enable text editing self.text.keyPressEvent(QKeyEvent) </code></pre> <p>But there are some Problems:</p> <ul> <li>Text editing is triggered by a single click, but I want double click (Might be a duplicate of <a href="https://stackoverflow.com/questions/10235411/qgraphicstextitem-editable-only-after-double-mouse-click">this</a>).</li> <li>You can't use the mouse to select text or move the cursor because the whole group is moved then.</li> <li>If you stop the editing the cursor won't disappear. (Though I know how to do that, if I find a way to activate and deactivate editing mode) </li> </ul> <p>I tried to catch the double click signal and switch to an edit mode that forwards the all the mouse events to the text. But I wasn't able to <em>activate</em> the editing process with the double click and furthermore I couldn't preserve the behavior to end the editing by clicking somewhere else.</p> <p>So I hope someone can help me. It might be enough to know how to manually activate and deactivate the text interaction mode of the <code>QGraphicsTextItem</code>. Thanks!</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.
