Generally speaking you need to "attach" a Find::IFindSupport implementation to your widget that has focus when the user presses ctrl+f. And provide a place for the find tool bar to show up by adding a Core::FindToolBarPlaceHolder into your layout.

Look how it's done e.g. for the Compile Output pane:
The OutputPaneManager adds a FindToolBarPlaceHolder for all output panes to it's layout:

outputpane.cpp:
OutputPaneManager::OutputPaneManager(QWidget *parent)
{
...
    mainlayout->addWidget(new Core::FindToolBarPlaceHolder(this));
...
}

The CompileOutputWindow itself specifies the IFindSupport to use by coupling the widget with the IFindSupport instance:

compileoutputwindow.cpp:
CompileOutputWindow::CompileOutputWindow(BuildManager * /*bm*/)
{
...
    Aggregation::Aggregate *agg = new Aggregation::Aggregate;
    agg->add(m_textEdit);
    agg->add(new Find::BaseTextFind(m_textEdit));
}

(BaseTextFind is an implementation of IFindSupport for QTextEdit and QPlainTextEdit.)
(Aggregate is used to combine several QObjects into one, that can then be "cast" to each other with Aggregation::query<PointerType>(object), see the documentation in aggregate.cpp .)

Good luck!
