    Re: Emulator Starting and ending

    Also, rather than starting HelloWorldQt.exe, try starting epoc.exe (same directory). This should bring up the emulator at its main menu.

    Re: Emulator Starting and ending

    Set a breakpoint near the start of your application and step through it.

    Re: Load failed -- TRKProtocolPlugin

    I guess the only part of that sequence I haven't tried is opening Carbide after starting TRK. I'll give that a shot next time I do a few rounds with the hardware.

    Re: CBase 69 in QT for S60 app

    Yeah, replace references to the widget with references to a "lazy constructor" method that will return the widget reference (from static pointer) if it already exists, create it if not.

    Re: EPOCSTACKSIZE - database application

    Depends on how much heap you have available vs how much the query needs. I would guess that you could eventually work out a way to query available heap and roughly determine the number of records...

    Re: EPOCSTACKSIZE - database application

    I know this sounds trite, but don't ask for more than 250 records at a time. Figure out how to process the data in chunks.

    Re: Multiple forms

    You might want to get a copy of "C++ GUI Programming with Qt 4" by Blanchette & Summerfield. It touches on this topic a little bit.

    Re: I need some help here folks!!!

    No panic code. And since I can't get the debugger to run I can't "look inside the application" to figure out what's wrong.
  13. Re: Where to get Examples and Demos Launcher App of Qt???

    And if you look in the same directory there's a file called "qt_demos.sis" that is a phone-installable image of the demos.
  14. Re: Where to get Examples and Demos Launcher App of Qt???

    Look inside the directory for your Qt install. There's a directory called "examples" and one called "demos".

    Doesn't anyone want to address this issue? Am I the only one having trouble with buttons getting "stuck"?
