    Doh, you are right of course. Then again, I would not draw the rectangle over the whole button, normally. But indeed, my version too will yield the same result at lower performance than yours.

    [SOLVED] Optimized compiling with Qt

    I recompiled Qt and OpenCV with -O3 flags (takes 9 hours) and then recompile my program with -O3 flag too. I can't believe the results! There was only 8 frames per second with normal configuration.... Now it's 38 frames per second :) This is my qmake.conf: @ qmake configuration for linux-g++ Written for GNU/Linux platforms that have both lib and lib64 directories, like the AMD Opteron. MAKEFILE_GENERATOR = UNIX TARGET_PLATFORM = unix TEMPLATE = app CONFIG += qt warn_on release incremental link_prl QT += core gui QMAKE_INCREMENTAL_STYLE = sublib QMAKE_CFLAGS -= -O2 QMAKE_CFLAGS -= -O1 QMAKE_CXXFLAGS -= -O2 QMAKE_CXXFLAGS -= -O1 QMAKE_CFLAGS = -m64 -O3 QMAKE_LFLAGS = -m64 -O3 QMAKE_CXXFLAGS = -m64 -O3 include(../common/g++.conf) include(../common/linux.conf) QMAKE_LIBDIR_X11 = /usr/X11R6/lib64 QMAKE_LIBDIR_OPENGL = /usr/X11R6/lib64 load(qt_config) @ God bless gcc ;)

    [quote author="leonidwang" date="1319600202"] But that's some problem out of Qt's scope. [/quote] Of course, but it is in the scope of your application. I was just suggesting you to investigate more...

    Thanks - that did it. I guess the buttons that are placed on Designer UI forms are automatically connected to the on_buttonname_clicked functions, but creating your own functions in that format creates some confusion.

    Alternating row colors in mac and linux

    I have had the same problem(?), with GTK and Qt. The reason for this behavior is the theme the computer is using - it may not have alternate colors for rows, even if you request it. This is the case at least with Linux Mint I use, no program has alternating row colors in their list boxes. So, basically, you should do nothing, as it is generally good to obey user's settings. If you want them visible, you should change your personal desktop settings.

    If you check the "source of QTableWidgetItem":http://qt.gitorious.org/qt/qt/blobs/4.7/src/gui/itemviews/qtablewidget.cpp you can find it out easily (setRowCount calls removeRows, which deletes the item).
