[Qt-interest] QLabel and QLineEdit setText are very slow in arm

[xuyaojun]

	hello!
	i have a example that updates 30 QLineEdit's text every 100 ms in a QTimer's slot.

    the example used by Qt4 is much slower than that used by Qt3.if i run the example used by Qt4 like this "./test -decoration -style no &", the CPU usage is coming down,but still higher than that used by Qt3.
    
	can anybody help me or give me some advise? thank you very much!

   the same question was asked in Qt Centre too.
