I want to make a more visual method of creating windows in Interface Writer, and I need to know if I can get the width and height of a PlusWnd object.  I'm guessing that I would need to register the WM_SIZE notification on the window, and also that I would need to use Interop, but what function?

And also, can I set the width and height of the window?

Edit: is this on the right lines?

You can also use MoveWindow instead of SetWindowPos.
As for retrieving the window's dimension, use GetWindowRect (if there's no need to get notified every time the dimension is changed)

I would imagine he would so that he could update the xml to reflect the new size

Javascript code:

---

var WndTest = MsgPlus.CreateWnd("Interfaces\\Test.xml", "WndTest", 0);
WndTest.RegisterMessageNotification(0x5, true);
function OnWndTestEvent_MessageNotification(PlusWnd, Message, wParam, lParam)
{
    if (Message === 0x5)
    {
        WndTest.SetControlText("EdtWidth", "");
        WndTest.SetControlText("EdtWidth", "");
    }
}

Javascript code:

var width = lParam & 0xFFFF;

Javascript code:

---

var height = (lParam >> 16);

Ok, that works great!

Next question: can I set the width and height of the window?  I've tried this:

Javascript code:

---

Interop.Call("user32.dll", "SetWindowPos", WndTest, null, 0, 0, 300, 200, SWP_NOMOVE | SWP_NOZORDER);

---

You need to pass the handle to WndTest, not the object, don't you?

EDIT: Well I mean from WndTest to the function... before someone says something

True.    Ok, but now I have another problem.

Javascript code:

---

var SWP_NOMOVE = 2;
var SWP_NOZORDER = 4;
 
var WndTest = MsgPlus.CreateWnd("Interfaces\\Test.xml", "WndTest", 0);
WndTest.RegisterMessageNotification(0x5, true);
WndTest.SetControlText("EdtWidth", 400);
WndTest.SetControlText("EdtHeight", 300);
 
function OnWndTestEvent_MessageNotification(PlusWnd, Message, wParam, lParam)
{
    if (Message === 0x5)
    {
        WndTest.SetControlText("EdtWidth", (lParam & 0xFFFF));
        WndTest.SetControlText("EdtHeight", (lParam >> 16));
    }
}
 
function OnWndTestEvent_CtrlClicked(PlusWnd, ControlId)
{
    if (ControlId == "BtnSize")
    {
        Interop.Call("user32.dll", "SetWindowPos", WndTest.Handle, null, 0, 0, WndTest.GetControlText("EdtWidth"), WndTest.GetControlText("EdtHeight"), SWP_NOMOVE | SWP_NOZORDER);
    }
}

Have you tried Tracing the EdtWidth and EdtHeight values? I've got a feeling it might not be reading them right. Don't know, but it might have something to do with the type conversion, although I would have imagined it would convert to an integer ok.

EDIT: parseInt... Does that mean I was right (even if I was late )

I think the missing pixels in the size may be something to do with the window borders possibly? 32 pixels for a top border seems about right to be honest

Ok, I'm adding 6 to the width and 32 to the height, which counter-acts the borders.  Seems to work great!

One other thing...  is there a way to convert dialog units to pixels, and back again?

I think it's all dependant on screen resolution and some other factors, including font from what I've read, but the topics mostly all relate to VB and C++...

EDIT: http://www.freebasic.net/forum/viewtopic.php?p=83555 <-- Might Help

Looks a bit confusing...

The MapDialogRect function converts the specified dialog box units to screen units (pixels). The function replaces the coordinates in the specified RECT structure with the converted coordinates, which allows the structure to be used to create a dialog box or position a control within a dialog box.

I didn't check, but I thought maybe you could reverse the process?

If this is to convert the units from pixels (from the window) to dialog units (inside the xml), then can't you just force the measurements in pixels? I know it's probably not quite what you want, but it's guaranteed to look the same and will save having to add functions or classes to figure it out for you.

That's what I've thought about doing.  The user can always change it to dialog units if they want, but if they use the builder, then it'll have to be in pixels. 



That's what the builder will look like.    Suggestions welcome.

Edit: I really doubt the feasibility of this, but I'm going to ask anyway.  Is there a way of working out the co-ordinates of a rectangle drawn with the mouse onto a Plus! window?  Would this need a certain control?  If this isn't possible, would I be able to record two clicks (one for the top-left, one for the bottom-right)?

Looks great!

Keep up the good work!

Hmm...    I'll have to think about it.  For now, I need some sleep and preparation for exams.

I've had a look at the two files, but I'm not exactly sure how to implement it.  How would I be able to draw a rectangle over a Plus! window, and get the left/top/width/height values in relation to that window?
