Re: Can you display a bitmap with/inside of a sizer?
Hi James,
Well really I find sizers are a bit problematic too. At the beginning I
did them just as you are doing. Then I started drawing the more
complicated ones out on a piece of paper before starting and now I have
a standard layout which I reuse so that I have a standard header, a main
panel and a standard footer with a standard set of buttons in it. The
main panel still requires some thinking, but I would have used the
nested sizers idea that you used. Wx::GridBagSizer is a bit more
complicated, but would also have worked, that way you might have been
able to do the whole thing with one sizer.
Regarding the memory leak, I thought I had it. I made a number of
changes to make the code more streamlined and efficient and lo and
behold the leak disappeared only to pop up else where.
It's driving me a bit crazier than I was anyway, and worse, I don't even
know if it's causing the video crash! Any suggestions welcome!
Thanks for asking,
Steve.

Made the top level sizer horizontal, containing a left and right
vertical, containing text controls, bitmap, and buttons.
Will post once I add a few more bells and whistles.
Thanks again,

But, of course, one question leads to at least one more.
I would like the bitmap to be displayed to the right of a column
of TextCtrls. Currently the TextCtrls are being displayed under
the bitmap now that I'm not using an onPaint event . Do I need to
create two sub-panels with sub-sizers, one for the bitmap and one
for the TextCtrls? Or should the top sizer be a horzontal rather
than vertical? Trying to make some sense of this sizer stuff.

Hi James,
You want Wx::StaticBitmap, like this:
my $bmp = Wx::Bitmap-new(path/to/bitmap.png,
wxBITMAP_TYPE_PNG) ;
my $sbm = Wx::StaticBitmap-new($parent, wxID_ANY, $bmp,
wxDefaultPosition, wxDefaultSize, );
$sizer-Add($sbm, 0, 0, 0);

Good day!
I'm working on a little app to design common emitter
amplifiers. I created a circuit schematic with Eagle and
exported it to a PNG file.
I am currently displaying the PNG at a fixed location of
the screen with:
Wx::Event::EVT_PAINT($self, sub {
my ($self, $event) = @_;
My $dc = Wx::PaintDC-new($self);
my $bmp = Wx::Bitmap-new(CEAmpImg.png,
wxBITMAP_TYPE_PNG);
$dc-DrawBitmap($bmp, 150, 50, 1);});
If would be nice if I could blend this in with the sizers
that are controlling the layout of the input and output
TextCtrls.
Thanks for your ideas.

Re: Can you display a bitmap with/inside of a sizer?
Steve:
You are already beyond me on looking for the memory leak based on your PM
post. The wxBook has a section on finding memory leaks, but what you are
doing with Valgrind is probably more advanced. Wish I could help more...
I like your idea for a standard layout - Header/Main/Footer. I need to work
that into my new app boiler plate file. It's amazing how many lines are
required for the sizers! Getting there. It makes more sense now that I have
it working. Nice to have example code to look at. Need to get github set up
on this laptop so I can add this to my examples repository.
For what it's worth, attached is my latest learning exercise.
