Hi Anton,

I have now moved unto using QT 5.4.1  and QWT 6.1.2

Things appear to work well.

However, looks like QT5 references an openGL 3D acceleration library.

So, upon startup we get an error.  Nevertheless, the caQtDM App launches and runs nicely.

Have you seen the error below?

[email protected] caQtDM_Tests]$ startDM tests.ui &

[[email protected] caQtDM_Tests]$ 
caQtDM must be in path and QT_PLUGIN_PATH must be defined correctly
stylesheets and ui files should be located in CAQTDM_DISPLAY_PATH where you will
save your ui files. You can copy them from caQTDM_Tests

see also caQtDM switches for options

caQtDM -- file <caQtDM_stylesheet.qss> loaded as the default application stylesheet
caQtDM -- file = <tests.ui>
caQtDM -- file <stylesheet.qss> replaced the default stylesheet
caQtDM -- viewer will disable monitors for hidden pages of QTabWidgets, in case of problems
          you may disable this by not defining IO_OPTIMIZED_FOR_TABWIDGETS in qtdefs.pri
caQtDM -- created shared memory

static QPixmap QPixmap::grabWindow(WId, int, int, int, int) is deprecated, use QScreen::grabWindow() instead. Defaulting to primary screen.

Cheers,
