<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">rather than looping, can we use FontMetric's maximumCharacterWidth
* numChars.
Then we could kill sizeHelper competely (FontMetric's didn't exist when this was written)</pre>

I did a quick test and maximumCharacterWidth returned about twice the width actually needed.</p></pre>

That means, I have to test 0-9 for hours/minutes/seconds, 0-2 for tens of hours and 0-5 for tens of minutes/seconds. Otherwise the constructed times will be invalid.
This can be done with three loops and it would bring down the amount of advanceWidth and formatTime calls from 24+60=84 to 3+6+10=19.</p></pre>

At which point it doesn't matter if it's a valid time or not. You can even format 12:12 with Qt.formatTime and then replace the numbers with your placeholder number.
In other words, the time format /is/ known in advance.</pre>

This causes the entire applet to change its width (if the time is the widest displayed item). This in turn can cause all other applets in the same panel to move whenever the displayed time changes.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This patch uses FontMetrics to iterate over all possible time strings (with different width) and chooses the widest of them as reference for the fixed width of the time label.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This way the width of the applet stays the same (unless the date is displayed and changes). The text remains centered though, which means that it can still move within the applet when the time changes.</p></pre>
