Suppose my history looks like this:
- plasmashell
- konsole
- dolphin</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">now imagine i type "plasma". It should then show:
- plasmashell</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Thus far it probably works fine.
Now imagine i clear whatever i typed (so a clean inputfield). All without closing krunner! When i clear it the history probably shows one entry:
- plasmashell</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">What happened to the other two?
Well, you've rewritten history when i typed a search query.
And because you call "runnerWindow.history = history" it will call the C++ setHistory method which will overwrite your history value in the config.. Ouch!</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I could be wrong, but this is how i think it behaves when reading the code.
I think you should use something with a tree. A radix tree would be the easiest, fastest and cheapest in memory, but that doesn't exist in Qt nor the C++ STL.</p></pre>

Also, I forgot to enforce a limit on the number of history items.</p></pre>

It also has some shortcomings due to ComboBox:</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">1.) You cannot use the arrow keys to cycle between entries (when the popup's not opened) because arrow keys navigate through results
2.) forceActiveFocus() on the ComboBox will not activate the embedded TextField - when you had opened the popup there's a slight chance the input field won't get focussed I'll prepare a Qt patch for this.
3.) Before Qt 5.4.2 (not sure if my patch ended up in 5.4.1) pressing space in the edit combobox will open the popup, not insert a space (nasty show stopper)
4.) Plasma's edtiable ComboBox looks a bit strange imho
5.) Plasma's editable ComboBox doesn't support clearButtonShown
6.) Plasma's ComboBox has strange bullets and margins in it, that's probably a bug in Plasma Style (need to look what Desktop style does differently from us)
7.) ComboBox doesn't have a cursorPosition, I'll prepare a Qt patch for this.</p></pre>
