<dd><p>Cross-toolkit “model” representation of a GUI layer object.</p>
|
||
<p>A <code class="docutils literal notranslate"><span class="pre">GUIObject</span></code> is a cross-toolkit “model” representation of a GUI layer object, for example, a
|
||
table. It acts as a cross-toolkit interface to what we call here a <a class="reference internal" href="#hscommon.gui.base.GUIObject.view" title="hscommon.gui.base.GUIObject.view"><code class="xref py py-attr docutils literal notranslate"><span class="pre">view</span></code></a>. That
|
||
view is a toolkit-specific controller to the actual view (an <code class="docutils literal notranslate"><span class="pre">NSTableView</span></code>, a <code class="docutils literal notranslate"><span class="pre">QTableView</span></code>,
|
||
etc.). In our GUIObject, we need a reference to that toolkit-specific controller because some
|
||
actions have effects on it (for example, prompting it to refresh its data). The <code class="docutils literal notranslate"><span class="pre">GUIObject</span></code>
|
||
is typically instantiated before its <a class="reference internal" href="#hscommon.gui.base.GUIObject.view" title="hscommon.gui.base.GUIObject.view"><code class="xref py py-attr docutils literal notranslate"><span class="pre">view</span></code></a>, that is why we set it to <code class="docutils literal notranslate"><span class="pre">None</span></code> on init.
|
||
However, the GUI layer is supposed to set the view as soon as its toolkit-specific controller is
|
||
instantiated.</p>
|
||
<p>When you subclass <code class="docutils literal notranslate"><span class="pre">GUIObject</span></code>, you will likely want to update its view on instantiation. That
|
||
is why we call <code class="docutils literal notranslate"><span class="pre">self.view.refresh()</span></code> in <a class="reference internal" href="#hscommon.gui.base.GUIObject._view_updated" title="hscommon.gui.base.GUIObject._view_updated"><code class="xref py py-meth docutils literal notranslate"><span class="pre">_view_updated()</span></code></a>. If you need another type of
|
||
action on view instantiation, just override the method.</p>
|
||
<p>Most of the time, you will only one to bind a view once in the lifetime of your GUI object.
|
||
That is why there are safeguards, when setting <code class="docutils literal notranslate"><span class="pre">view</span></code> to ensure that we don’t double-assign.
|
||
However, sometimes you want to be able to re-bind another view. In this case, set the
|
||
<code class="docutils literal notranslate"><span class="pre">multibind</span></code> flag to <code class="docutils literal notranslate"><span class="pre">True</span></code> and the safeguard will be disabled.</p>

<p>This view starts as <code class="docutils literal notranslate"><span class="pre">None</span></code> and has to be set “manually”. There’s two times at which we set

the view property: On initialization, where we set the view that we’ll use for our lifetime,
|

and just before the view is deallocated. We need to unset our view at that time to avoid

calls to a deallocated instance (which means a crash).</p>
