[GUI] qt4 no longer supported?

[MarcinWieczorek]

Hello

I got this error when compiling dash gui with qt4:

qt/masternodelist.cpp: In constructor 'MasternodeList::MasternodeList(const PlatformStyle*, QWidget*)':
qt/masternodelist.cpp:36:55: error: 'class QHeaderView' has no member named 'setSectionResizeMode'
     ui->tableWidgetMyMasternodes->horizontalHeader()->setSectionResizeMode(QHeaderView::Interactive);
                                                       ^
qt/masternodelist.cpp:44:53: error: 'class QHeaderView' has no member named 'setSectionResizeMode'
     ui->tableWidgetMasternodes->horizontalHeader()->setSectionResizeMode(QHeaderView::Interactive);
                                                     ^
Makefile:5739: recipe for target 'qt/qt_libbitcoinqt_a-masternodelist.o' failed

I've looked it up on the net:

void QHeaderView::setSectionResizeMode(ResizeMode mode)
This function was introduced in Qt 5.0.

source: http://doc.qt.io/qt-5/qheaderview.html#setSectionResizeMode

I think this means the gui is impossible to build with qt4, build-unix.md is misleading and --with-gui=qt4 option is unusable.

Should be fixed in #862
Thanks for reporting!

Should I close this? The PR has been merged.

Did you test if it works now? If it works it can be closed :-)
