Re: Missing gui component

[Bruce Steers <bsteers4@xxxxxxxxx>]

No not at all.

This was a program written 9 years ago and forgotten about that was
explicitly set to use gb.gtk
Now the user has a system that does not have gtk2 so his gambas install did
not include a gb.gtk component, only gb.gtk3

That's why it's never a good idea to explicitly set a particular gui
toolkit for a program meant for the public domain as you do not know what
toolkits the user may have.
It is always best to use gb.gui to automatically select the available
system toolkit. (or gb.gui.qt to force automatic qt4/qt5/qt6 library
switching)
