Hi, I know I'm a little late to the party, but while trying to port our project to Qt5, I just discovered that the QApplication constructor that takes a "bool GUIenabled" argument has been removed. I cannot find any mention of this in the official change lists.
This change is quite unfortunate for us because we have some programs with "runtime optional" GUIs. These programs would simply instantiate a QApplication, passing true as the GUIenabled argument only if the "DISPLAY" environment variable was not empty. This all worked nicely. Now, without that constructor, I have to explicitly instantiate QApplication or QCoreApplication on the heap and keep it in a pointer. Another problem is that the change does not break existing code, because the "normal" QApplication constructor (int&,char**) actually has a third argument (int) that is hidden from the docs. This means that existing code will continue to compile, but pass one or zero as the third argument, which normally defaults to QT_VERSION (0x05****). I realize that this is more of a complaint than a question, but maybe somebody here can shed some light on the story. -- Mit freundlichen Gruessen / Best regards Marc Schmitzer SW-Entwicklung ESWL / ESWT Software development ESWL / ESWT ***************************************************************** Richard Wolf GmbH Web: http://www.richard-wolf.com ***************************************************************** +++ Richard Wolf GmbH, Pforzheimer Strasse 32, 75438 Knittlingen Managing Directors: Siegfried Karst, Juergen Pfab, Juergen Steinbeck.
