[Lazarus] Order of OnCreate and OnActivate in Qt4

[Vojtěch Čihák]

Hi,
 
I met strange bug today. I have these lines in .lpr:
...
Application.CreateForm(TFrmMain, FrmMain);
...
Application.CreateForm(TFrmContext, FrmContext);
...
 
and the order of events in Qt and GTk2 is:
FrmMain.Create
FrmContext.Create
FrmMain.Activate
 
Today I used tool qtconfig and changed style (Appearance) from Plastique to QtCurve. Now my code crashes, order of events is:
FrmMain.Create
FrmMain.Activate
CRASH, because code in OnActivate assumes that FrmContext already exists.
 
So, Qt4+Plastique has different order of events than Qt4+QtCurve.
Unfortunately, I cannot reproduce with simple demo.
 
What I'm doing wrong? Do I rely on something that is not guaranteed?
 
Thanks.
