    <p>I need to show some treeview item text striked out text into a QT treeview from Ruby. After some reading on QT documentation and much coding, I found that only when rendering font in bold, also the strikeout was rendered.</p> <p><img src="https://i.stack.imgur.com/pnt56.png" alt="Resulting treeview rendering."></p> <p>So I wonder, where I'm doing wrong? This is the code to achive the result shown above. Note as I set strikeout for every even row item. I'm using Ruby 1.8.7 and Qt 4.6.2 and qt4ruby 4.4.3-6 on Mandriva Linux.</p> <pre><code>require 'Qt4' require 'date' class MyStandardItem &lt; Qt::StandardItem def initialize(str = nil) super str end def data(role = Qt::UserRole + 1) return super(role) unless role == Qt::FontRole ret_val = Qt::Font.new() #parameters for "fromString":font family, pointSizeF, pixelSize, QFont::StyleHint, QFont::Weight, QFont::Style, underline, strikeOut, fixedPitch, rawMode ret_val.fromString "sans serif,-1,-1,0,0,0,0,0,0,0" case role when Qt::FontRole ret_val.setStrikeOut(true) if (index.row % 2) == 0 if index.column == 1 ret_val.weight = Qt::Font.Bold else ret_val.weight = Qt::Font.Normal end return Qt::Variant.fromValue(ret_val) end return ret_val end end Qt::Application.new(ARGV) do treeview = Qt::TreeView.new do model = Qt::StandardItemModel.new self head = [MyStandardItem.new "Qt v. #{Qt.version}"] head &lt;&lt; MyStandardItem.new("Ruby v. #{VERSION}") head &lt;&lt; MyStandardItem.new("Qt4Ruby v. 4.4.3-6 (Mandriva)") model.append_row head (1..10).each do |i| col0 = MyStandardItem.new 'some text' col0.check_state = ((i % 3) == 0)? Qt.Checked : Qt.Unchecked col0.checkable = true col0.editable= false col1 = MyStandardItem.new "line ##{i}" col2 = MyStandardItem.new((Date.today + i).strftime '%d/%m/%y') model.append_row [col0, col1, col2] end self.model = model show end exec end </code></pre>

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.
