For my attempt to fix the problems in the gtk2 TabControl implementation
I need some background information. Can anybody help me, or continue my
started update?
In the first step I try to keep the dummy page, that is created together
with the notebook widget, and use it for all tabs. I also managed to
have the associated dummy tab invisible, but at sudden the
implementation started to behave inconsistenly. Sometimes adding tabs
(in code) works, but in most cases no tabs are shown at all. Reverting
the code to the previously working implementation didn't help, so that
it looks like some random behaviour, as known from uninitialized local
variables.
It looks as if the random problem was caused by designtime tabs. The
gtk2 designer does not yet work properly, and strings added to the
TabControl.Tabs will prevent all tabs from becoming visible. Can
somebody find out why?
I've just uploaded the gtk2 patch as NewTab1.patch. Apply and rebuild
Lazarus, before using the new tabcontrol with gtk2.
