[C++] Window/Dialog: Which do I use and how?

Pages: 12
meesa (233)
I'm trying to learn the Win32 API, and since internet tutorials can only get you so far, I thought I'd take one of my console programs and convert it. (Yes, I've been on Google a lot)

For this application, I want a settings window, whether it's a dialog, or a window: I know not what I need. But what I want to to be able to do is have text and edit boxes, perhaps some check boxes, and it needs to scroll. Reason being that will be a good 30+ options, and I don't want a dialog box that long. (Not even sure if that'd fit on my screen.)

So the question is, what do I need to use, and where do I Start? I can use Google just fine, but when I don't know what I'm looking for, it's difficult. So please give me where to start, things to research, etc.

Thanks!

You don't see many scrolling dialogboxes.

What you do see are propertysheets - (which is a tabbed dialogbox).
If you open Internet Explore and bring up the options dialog - you will see what I mean.

You group your controls onto the various tabs.

But using a propertysheet dialog is more work.

Okay, so a window is what I need. However, I don't want tabs, what I need is kind of like what ID has in their advanced tab: the one where all those check box options are. However, I don't need check boxes, I need [Text] [Editbox] [Editbox] And I might need one or two checkboxes.

What you are describing I do very frequently meesa. I do it in Windows CE for data recorder programs because the screen is like three inches by three inches or so. Other than code directly from one of my Windows CE programs, I don't believe I have a simple C/C++ Sdk demo of this but I do have an exact demo of it in the PowerBASIC language that is however exactly like C or C++ Sdk style except there are no semicolons at the ends of PowerBASIC lines.

Unless you are an experienced Sdk Api coder you won't understand one single thing about what I am going to describe, but perhaps the combination of my description and your desire to do it will suffice. Here goes.

A parent window is first created. A 'pane' window is then created as a child of the parent; however, it is created much larger than the parent; in fact large enough to contain hundreds or even thousands of text boxes if you want; The text boxes and labels (or check boxes, whatever), are then created as childs of the pane. You put a scroll bar on the parent, and move the pane about to bring various child window controls into view (the ones outside the parent are clipped and not visible). This is made possible by the fact that the x/y coordinates of a window in both the CreateWindow() call and the MoveWindow() call are typed as ints, which is a signed quantity, and so the pane can be scrolled within the parent's view space in negative and positive directions. I have a nice demo and detailed tutorial of this at a PowerBASIC website here....

http://www.jose.it-berater.org/smfforum/index.php?topic=2981.0

Its my tutorial #11 : Scrolling Controls In A Window

Again, while it isn't C code, it will translate line for line exactly to C (with minor modifications). However, if you don't know Sdk style Api coding you are likely to have problems. I believe all the code is there to be copied; you shouldn't have to join up at that forum (for members my programs can be downloaded as they are in zips). I probably ought to translate it to C/C++. Probably take me an hour.

Couldn't the ScrollDC function be useful in this situation??
(I haven't looked at your code so I don't know if you have mentioned/used this particular function)

You've got me gustgulkan! I never used ScrollDC. I'm pretty sure I used MoveWindow() in that example. There might be a MoveWindowEx(). Not sure. I'd have to check.

I did check out ScrollDC() just now in msdn and the parameters and usage look pretty similiar to ScrollWindow() and ScrollWindowEx(), which I frequently use for scrolling lines of text because it produces a much better and smoother scroll than outputting lines of text with a for loop or whatever.

I'm just not sure how well it would work scrolling controls however. The example I posted was a result of my need to accomplish what the original poster wanted, but I had to do it for Windows CE devices where the screen is quite small. Your recommendation of a tabbed dialog is also a good idea and workable. After I created my various apps with my window scrolling technique I did wonder if a tabbed dialog would be a better solution. Just the other day another fellow and I were discussing this exact issue, and he told me he implemented a Windows CE app with the tabbed dialog technique, but thought my solution might be a bit better. So I don't know which is best.

Thanks guys, I'll be looking into both methods, and I'll report back on the one I use. Your help is much appreciated.

Here's an exact line for line translation of the PowerBASIC code. Compiled with 32 bit XP SP3 Code::Blocks 8.05....

Hey that code looks very familiar. :) Just note that he stores a pointer to hPane in the window extra bytes, not in the hPane class but in the class for the actual application window.

Wow! Thanks!

I'll try it out this week and let you guys know how it goes.

A curiosity question: Which is better, _T("text") or L"text"? Or is it a matter of preference?
Incubbus (678)
TEXT() is better, because it inserts what You need. Unicode text for unicode and so on...
freddie1 (1838)
I want to improve that scroll code when I get a chance; hopefully tomorrow, so check back.

I can tell you that that code will definitly help! Right now I'm working on just getting everything to look right in the window, then once I get the format figured, I'll be working on the scrolling.

An interesting dilema about that is that it is possible to do without the "pane" class by just using a label control, i.e., "static" for the pane and then moving the label through its "virtual" range within the parent. That saves registering a seperate class for the "pane" and also eliminates the window procedure for the pane. However - here's the kicker - the Submit button is a child of the pane and hence the pane's Window Procedure gets WM_COMMAND messages when the button is clicked. I havn't checked how that would work by emiminating the pane and just using a label as the scrolling pane. The Window Procedure for the label is inside Windows. Granted you could hook (subclass) the label's Window Procedure, and perhaps that way catch clicks on the button. That complexity would pretty much eliminate the simplicity gained though by eliminating the pane class.

Quick question: Where did the 489 in vsi.nMax=489; come from? You said in the comments that the GetClientRect was for that variable, but then you just put a number yourself?

Edit: I noticed that hPane is where that number came from, but if that number is the same (Or actually less) than the pane, wouldn't that make scrolling pointless?
