Win32::GUI Bitmaps on buttons?

HaB has asked for the wisdom of the Perl Monks concerning the following question:


Experiencing the pitfalls of working with a module that is still in beta, and that the author hasn't finished documenting yet. In Win32::GUI, I am trying to create a toolbar, with 5 buttons, each of which should have a picture on it. I am using the sample script that comes with Win32::GUI as a guideline, but I don't see many differences aside from the number of buttons I'm adding, (5) as opposed to what the sample script adds. (3)

So what I'm wondering is...does anyone know proper syntax/arguments for getting a bitmap onto a button? The documentation for Toolbars is not there, and only one bitmap method is described for Bitmap objects. The rest are TBD. I'm using the following code:

$main_toolbar = $main->AddToolbar( -left => 0, -top => 0, -width => $main->ScaleWidth-10, -height => 16, -name => "Toolbar" ); my $tb_bmp = Win32::GUI::Bitmap->new("c:\\devel\\adtserver_new\\toolba +r16.bmp"); $main_toolbar->SetBitmapSize(16,16); $main_toolbar->AddBitmap($tb_bmp, 5); $main_toolbar->AddButtons( 5, 0, 1, 4, 0, 0, 1, 2, 4, 0, 1, 2, 3, 4, 0, 2, 3, 4, 4, 0, 3, 4, 5, 4, 0, 4 );

I get the toolbar and the buttons, but they are blank, and henceforth not very useful. [; Also, any further help on what the args for AddButtons are used for would help immensely. I know the first arg is the number of buttons to add, and the 2nd column in each group of five is the number that's returned for the Click event. Everything else....*shrug* Anyone know what's up?

    The latest version of my Perl/Tk Newest Nodes Client uses bitmaps on the buttons. It's pretty rudamentary, but should show you the technique. I create the bitmap files (which are then stored in a hash) using a Solaris version of bitmap(1).

      I appreciate the response and all, but that doesn't really help me. The problem I'm having is specific to Win32::GUI, and I'm not using Tk. The docs for Bitmaps and Buttons are incomplete in that package, so I'm trying to find out if anyone knows the args and the arg order.

    Hmm.. not sure about the backgrounds/bitmaps for buttons. But here are the options..

    # (@)METHOD:new Win32::GUI::Button(PARENT, %OPTIONS)
    # Creates a new Button object;
    # can also be called as PARENT->AddButton(%OPTIONS).
    # Class specific %OPTIONS are:
    # -align => left/center/right (default left)
    # -valign => top/center/bottom
    # -default => 0/1 (default 0)
    # -ok => 0/1 (default 0)
    # -cancel => 0/1 (default 0)

    I would assume that generic options would work with this as well (ie -color etc...). But, don't take my word for it, I've never used win32::gui.

    update: Played with it a little bit. Looks like what you need to do is something like this:
    $TB = $W->AddToolbar( -left => 0, -top => 0, -width => $W->ScaleWidth-10, -height => 100, -name => "Toolbar", ); $B = new Win32::GUI::Bitmap("unkfolder.bmp"); $C = new Win32::GUI::Bitmap("two.bmp"); $TB->SetBitmapSize(16, 16); $TB->AddBitmap($B, 1); $TB->AddBitmap($C, 2); $TB->AddString("ONE"); $TB->AddString("TWO"); $TB->AddButtons( 2, 0, 1, 4, 0, 0, 1, 2, 4, 0, 1, );
    That's pretty much stolen directly from the sample. Basically, open the bitmaps, assign the size the bitmap will be on the toolbar, and then add the bitmaps to the relative button location (1,2,3 etc). Does that help?
    Another update:
    In the code above, ($B, 1) and ($C, 2) should read as ($B,0) and ($C,1).
