Hey, im developing a PtCompound-subclass for QNX4.25
Can anybody send me another example source code for
PtCompound? Im not getting the freeking widget to run…
thx in advance
oh yes, mailto: micro a planetschranz(dot)de
removed mail-link due to heavy spam …
Made it to compile, but linking fails, even i made the code minimum …

so the problem described above is solved …
Doing executable without mainfunction won´t work.
I put in a Main function now,
problem is, as soon as i include my subs, lets say creating an Label in dflts function, and including it in PtCreateWindows Args from my PtCompound-deriviate, makes SIGSEGVing the App …
I put my code now:
LabelCompound.h:

There may be some wired namings, since i changed and deleted a lot for posting, but in general thats all what is run through.
Thx for help[/code]
Found the mistake, you have to set Pt_PROCREATED ind dflts_f, but nevertheless there won´t show up a Label in my App …
The label will show up as soon as i create just the label, but not within the compound …
Is there anybody having experience with PtCompound or has some other example?
I´m really getting tired of Custom Widgets
