<dd><p>Cross-toolkit GUI-enabled progress window.</p>
<p>This class allows you to run a long running, job enabled function in a separate thread and
allow the user to follow its progress with a progress dialog.</p>
<p>To use it, you start your long-running job with <a class="reference internal" href="#hscommon.gui.progress_window.ProgressWindow.run" title="hscommon.gui.progress_window.ProgressWindow.run"><code class="xref py py-meth docutils literal notranslate"><span class="pre">run()</span></code></a> and then have your UI layer
regularly call <a class="reference internal" href="#hscommon.gui.progress_window.ProgressWindow.pulse" title="hscommon.gui.progress_window.ProgressWindow.pulse"><code class="xref py py-meth docutils literal notranslate"><span class="pre">pulse()</span></code></a> to refresh the job status in the UI. It is advised that you call
<a class="reference internal" href="#hscommon.gui.progress_window.ProgressWindow.pulse" title="hscommon.gui.progress_window.ProgressWindow.pulse"><code class="xref py py-meth docutils literal notranslate"><span class="pre">pulse()</span></code></a> in the main thread because GUI toolkit usually only support calling UI-related
functions from the main thread.</p>
