[Qgis-developer] Lineedit with clear button

[Alexander Bruy]

Hi all,

there are several dialogs in QGIS where we have filters, for example
Expression builder, Style manager, Plugin manager etc. This is great
feature, but to remove a filter one has to erase text (select it with
mouse and press Del or using Backspace).

I think it is much better to provide small button to clear filter. So I've
implemented new widget QgsFilterLineEdit that provides lineedit with
builtin clear button. You can find screenshots here:
 - without text [0]
 - with text [1]

If there are no objections I can push code to master.

BTW, there is also similar ticket in SEXTANTE tracker [2]
