However, this was (at best) a partial success, since then the main composition view is about 1 pixel high by 10 pixels wide, and immovably sat on top of the menu bar. Thus I conclude that the un-commenting of line 910 was done for a reason. Hmm. Any more ideas? Is it just that I still have Qt 4.4? I see that since r10537, Qt 4.5 is needed to even compile trunk: src/gui/widgets/FileDialog.cpp: In static member function ‘static QString Rosegarden::FileDialog::getOpenFileName(QWidget*, const QString&, const QString&, const QString&, QString*, QFlags<QFileDialog::Option>)’: src/gui/widgets/FileDialog.cpp:74: error: ‘class Rosegarden::FileDialog’ has no member named ‘setOptions’ I'm reluctant to upgrade my Ubuntu 8.04 LTS to anything newer, but maybe it's a price I'll have to pay to keep up with the bleeding edge. Are you intending to support Qt 4.4?
