It just clutters the code, and you would have to fix it in about every second line of the application anyways, should it ever happen (it doesn't on linux).</p></pre>

Not doing this would either mean not using a pointer at all (= abandoning the patch), or not checking if the allocation succeeded. And that's not acceptable either. No matter how likely an application is to crash anyway if an allocation fails.

IMO it's pedantic and useless. We are not writing life-critical software; if your system is out of memory, your IDE crashes, such is life. On Linux it doesn't do anything <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">anyways</em> in the default kernel configuration, since allocations always succeed.</p></pre>

Pending events can in that case be (generated and) delivered to objects that were already deleted.
According to the documentation, one should prefer to use <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">QObject::deleteLater()</code> rather than the regular, direct <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">delete</code> whether it be explicit or implicit.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I've long used a local patch that uses this approach in order to prevent a recurring crash after using the context menu of the "ideal dock widget". Somehow I never put it up for review here, apparently.</p></pre>
