[perl-win32-gui-users] Combobox help
First, I want to send huge amounts of thanks to Mr. Calpini, for his work
in developing this. I've always believed I couldn't really do development
for Win32, because the Win32 API was so cryptic. Having an actual Perl
front end -- a language with which I'm familiar from the Unix world -- is
wonderful beyond belief. Thank you!
I've run into a couple of problems, and until now have been able to find
the answers on the 'net or on this list. This one, though, has me
stumped. I've seen others with the same issue, tried the solutions
recommended for them, and no dice.
Basically, I have a Combobox that I'm trying to display to the user. I've
populated it with, for the test, about 12 items. It displays only the
original items; the others are accessible through the keyboard, but not
up-down scrolling list is available. It just shows the first 10 or so.
$Step2Source = $NewDlg->AddCombobox (
-name=>"NewJobWizardStep2Source",
-tabstop=>1,
-left=>145,
-top=>168,
-width=>280,
-height=>100,
-addstyle=>WS_VISIBLE | 3 | WS_VSCROLL | WS_TABSTOP);
if ($numjobs > 0) {
my $thisjob;
foreach $thisjob (sort keys %joblist) {
$thisjob =~ s/.firebak$//i;
$Step2Source->InsertItem ($thisjob);
}
}
I've tried about every variation on this I can think of, with no dice.
The Combobox appears, and can drop down, and everything's there. But no
listbox. I've tried using the scroll=>1 parameter. Tried just about
every combination of the styles I can think of, including -addstyle and
-style both. No luck. As far as I can tell, my code is basically
identical to all the examples out there. Ideas?

Re: [perl-win32-gui-users] Combobox help
I grabbed that package. Still can't quite figure it out -- it's as perplexing as any Visual environment. I've messed with it like crazy... the only thing I can figure out is that I've encountered some bug in the library, that's being triggered by something else in the code. The package looks good, I'll admit. I'm just still a bit at a loss as to how to actually *use* it. :) So I may try that. On the other hand, it might just do the same thing to me, so I'm not sure. Anyway, I appreciate your response, and if you have any ideas, please let me know.

Re: [perl-win32-gui-users] Combobox help
Johan, you're a lifesaver. I put it in explicitly as 0x0020 | ... And it worked. I'm not sure why that would be any different, but, well, there you have it :) Joel On Sun, 11 May 2003, Johan Lindstrom wrote: > At 01:13 2003-05-11 -0500, Joel Ricketts wrote: > >Basically, I have a Combobox that I'm trying to display to the user.

[perl-win32-gui-users] More Combobox Help
Johan was able to help me by including the options for WS_VSCROLL. For some reason, using the name of the constant fails utterly, while using it by number works fine. My combobox drops down now. One little annoyance left: When it drops down, the first five items in the list (i.e. all that are displayed initially) have a sort of grey background to them behind the text. Once I scroll down, any options below that do not have the grey background and are correctly shown with black text on white background. When I scroll back up, the first five options are now shown normally. While the program is usable, this is disconcerting to the end user. Any suggestions? I'm looking into using TheGUILoft, perhaps, just to see if it might help. Johan showed me the value of a few of the constants, but I'm not sure where I would get those -- do those come from Visual C++ header files? Could somebody possibly give me an idea where to find those values? I'm wondering if this is related to WS_VISIBLE or WS_NOTIFY, which I see people using, but am not sure the reason for them :) They may not be translating properly. >From what I have seen, the primary problem I'm running into is a lack of documentation. The size of the documentation project is, of course, massive. Still, it's sometimes hard to figure out what options are available, and what options apply to what classes, and what they do. As somebody who hasn't done GUI programming under Windows before, some of the options and methods aren't intuitively obvious. More than anything, having better documentation of the library would make this package go from being great to superb! Unless somebody knows where there is some, and I just haven't found it. I've been using Aldo's documentation off his web site, which is great as far as it goes, but isn't finished yet from the look of things. Any help would be appreciated! Thanks!
[perl-win32-gui-users] Existing problems
I'm having some issues with Win32::GUI that I was hoping people could help with. 1. In a Listview, is there any way to right-justify a column? I have a list of filesizes, but haven't found any way to right-justify one of the columns. I can live with it the way it is, but it would look nicer if I could right-justify ;) 2. In TreeView, the list of items will sometimes clear entirely when a node is closed. As in, the whole TreeView becomes blank. Is this something I'm causing in my code or inadvertently triggering? Or is this a known bug that I can't really work around? 3. In TreeView, is there any way to change the image associated with a node after it's been inserted? I've tried this; the image doesn't seem to change. 4. In TreeView, some of my icons seem to appear in monochrome. A few appear in full color. They were all created identically. Is there some special format I need to use to make them appear in proper colors? 5. When using a listview with checkboxes, is there a way to set the initial state? I can't find any documentation on this feature. 6. When a treeview is first expanded such that the vertical scrollbar appears for the first time, the control goes blank until I find the scrollbar and scroll down. Is there a workaround for this behavior? Thanks. Any help would be appreciated. :)
RE: [perl-win32-gui-users] ListView question: What event should I use when checking an item on a list?
I've used the following code to get notified when an item changes:
sub DirTree_Click # Anytime user clicks in our window
{
my ($x,$y) = Win32::GUI::GetCursorPos();
# Grab mouse pointer location
my ($left,$top,$right,$bottom) = $dirtree->GetWindowRect ();
# Subtract upper left of our control
$x -= $left;
$y -= $top;
my ($node,$ninfo) = $dirtree->HitTest ($x, $y);
# See where they clicked. $node will be the node they
# clicked on; $ninfo will be a number indicating where.
return if ($node eq "0");# Don't remember why I added this :)
return if ($ninfo != 64);# '64' means they clicked the
# checkbox

I found the answers to a few of these, and a little more info. Still need help with some of them.

The ItemCheck() function is supposed to do this, at least from what I see in the c++ code for Win32::GUI. However, for whatever reason, it doesn't work. The items always appear unchecked until I actually click on them. I'd like to be able to show the current state, however. > 6.

Yes, this is the case. Unfortunately, I kinda need to do it. Any idea how I can get around this behavior? I've tried just about everything I can think of, but it still seems to blank no matter what I do :/ It's like it expands, then immediately blanks. I can see it expand for a split second.
