I have two problems with that:
1. To be able to use TextEditor in IDE during desing and coding I need to activate gb.qt5.ext on my system (as I have no qt4 on this system, nor gb.qt4 packages). This will activate gb.qt5 as well which in its turn creates an incompatibility with the selected gb.gui.qt. So, to design and test I have stick with qt5, no problem, but.... see 2.
2. If I now make a package to install on a qt4 system it will not install, as it packaged with gb.qt5 and gb.qt5.ext, and these systems only have gb.qt4 and gb.qt4.ext (older systems as I said).
So, to make a package for both qt4 and qt5 I need gb.gui.qt which will install depending on what is available on the target system. I can't package for gb.gui.qt as I have no gb.gui.qt.ext. And no gb.gui.ext also complains during compilation with a TextEditor on a form, so forget making a package without it, unless you remove the TextEditor of course...
As a workaround I would need to make a package on a qt5 system with gb.qt5 and gb.qt5.ext enabled as dependency and next on an older system make a package with gb.qt4 and gb.qt4.ext enabled as dependency.
So, I have a workaround, but it kind off makes no sense to have no gb.gui.qt.ext component so you can package applications using TextEditor gb.qt4/gb.qt5 independent.
But anayway thanks for thinking along,
