width reduced by 1px compared to the previous invocation of the file<br />
dialog.</p>
<p>While the patch worked on the surface when it was applied, the actual<br />
reasoning was wrong: The difference was not because of "extra resize()<br />
events", but because of a mismatch between what was read from the config<br />
(<tt style="background: #ebebeb; font-size: 13px;">placesViewWidth</tt>) and what was written to the config (<tt style="background: #ebebeb; font-size: 13px;">sizes[0]</tt>).</p>
<p>The actual reason <tt style="background: #ebebeb; font-size: 13px;">placesViewWidth</tt> and <tt style="background: #ebebeb; font-size: 13px;">sizes[0]</tt> are different is<br />
because of a previous error: It is assumed that the splitter sizes sum<br />
up to <tt style="background: #ebebeb; font-size: 13px;">availableWidth</tt>, while in reality this width also contains the<br />
width of the splitter handle. Upon <tt style="background: #ebebeb; font-size: 13px;">setSizes</tt>, Qt equally takes away<br />
width from both sides of the splitter to make everything fit.</p>
<p>While for the Oxygen and Fusion styles (3px and 4px splitter handle<br />
width, respectively) an adjustment of 1px did the trick, for Breeze with<br />
its splitter handle width of only 1px this did not work anymore due to<br />
rounding errors, it resulted in the config entry incrementing by 1px for<br />
every invocation of the dialog.</p>
<p>To fix the problem for every style, we simply take the width of the<br />
splitter handle into account and revert the previous fix. While we are<br />
at it, we refactor to make everything more DRY.</p>
