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?

Afaik not, that should work w/o problems. Never seen such kind of problem with different themes. In any case, without example project I cannot help.
