Displaying LONG filename on limited static control

I am writing a program and I'm on the file choosing part of it. I thought it a good idea for the user to see what file and the path they are choosing via a static control. Well, of course a filename can be really long, so how do I display this long path+filename in this limited amount of static area. How do you make a static control's display (on a window, not a dialog) with wordwrap? That could always work. Thanks!

just declare in the header


in the .h file

Code:

---


CStatic txtFileName;


in the .cpp file for the window

#define ID_FILENAME 101

....::OnCreate(.....)
{
      txtFileName.Create( sText,  dwStyle,  rect,  this,  ID_FILENAME );
.....
}

....::SetFileName( CString strFilename )
{
    CDC* pdc = txtFileName.GetDC();
    CSize size = pdc->GetTextExtent( strFilename );
    CRect r;
      txtFileName.GetWindowRect( &r );

    int area1 = r.Width() * r.Height();
    int area2 = size.cx * size.cy;
   
    if( r.Width() < size.cx && area1 < area2 + size.cy )
    {
          //resize the window
          txtFileName.SetWindowPos(NULL, 0, 0, r.Height() + size.cy, SWP_NOMOVE | SWP_NOZORDER);
    }             

    txtFileName.SetWindowText( strFileName );
}

I have not tested the above code but with some fine tuning it will work....

Well, I can only go so far with the static control. Otherwise, it'll be off the client and you won't be able to see it anyway. I think the best thing to do is to use a wordwrap static, but I don't know how to. Thanks...

Hey Garfield,

Just wandering i dont know how to do wordwraps but couldnt you use a multi lined edit box, if you removed the borders and made it read only and colour it the same as the background of your prog, then it would look like a standard static control, and the text would word wrap as nessecery.

Hope that helps,

As a suggestion: create an edit cntrl with the ES_READONLY style.
You can then fit the cntrl to whatever size you choose within the client area of the parent wnd while the user can use keys like END, HOME, arrows etc to move around the text without being able to change it. It also has the advantage of having the std edit cntrl context menu if your user wants to copy the contents to the clipboard.

edit: the background of the edit cntrl is set (I think) to COLOR_BTNFACE too instead of the more usual COLOR_WINDOW (see GetSysColor for more info).

Okay, I'll give the edit control suggestion a try. I'll also use ES_AUTOSCROLL (I think this is the constant) so when I set the window text, it should automatically go to the end (which is the most recent filename/dir), right? Thanks...
