Re: [Texmacs-dev] Experimental Qt port

[Alvaro Tejero Cantero]

My compilation error is still present with latest CVS update and my
libqtdev is version 4.3.4 (ubuntu 8.04's stock version)

./Plugins/Qt/qt_widget.cpp: In member function 'virtual blackbox
qt_view_widget_rep::query(slot, int)':
./Plugins/Qt/qt_widget.cpp:365: error: cast from 'QWidget*' to 'int'
loses precision
./Plugins/Qt/qt_widget.cpp: In member function 'virtual blackbox
qt_window_widget_rep::query(slot, int)':
./Plugins/Qt/qt_widget.cpp:1144: error: cast from 'QWidget*' to 'int'
loses precision
