Re: [perl-win32-gui-users] Memory Usage

[Jez W. <je...@je...>]

Thanks for the detailed reply.

I broke my app down and found it was taking about 2 meg for all the =
controls/windows - the rest was due to my code or other modules. I'm =
considering using a new design approach were I'll be using child windows =
as containers for groups of controls - potentially there could be lots =
of these windows - roughly how much memory does a window use?

Cheers,

jez.

  Yep, there's a "PERLWIN32GUI_USERDATA" structure for every control and =
window. This structure is chunky, and has references off to other =
structures in it, such as window names, cursors, accelerator tables, NEM =
events, etc. It could probably be optimized down.

  The reason it uses more memory is that it supports and does more =
stuff. When you're writing an application to do, say, a calculator, you =
know exactly what buttons and windows you want, where you want them, and =
what you're doing, so you can build your C windowing code around your =
final goal. When you compile it, things get optimized even more by the =
compiler. With Win32::GUI there is no "final goal" and everything the =
Perl coder could conceivably want to do has to be supported, making it's =
footprint quite large.

    Hi,

    I've noticed that my app uses lots of memory on start up (35 M) =
compared to other "similar" applications (around 12 M) I'm on XP. I've =
got lots of windows and controls which are created at the start - is =
there Win32::GUI memory overhead for each control/window? Or should I =
start considering this as some sort of bug in my code?

    Cheers,

    jez.
