Re: [platform-ui-dev] Wizard pages show up blank

[Jim Zhang <jzhang@xxxxxxxxxx>]

Upon closer inspection I found that
when the page in question does not show up correctly, the following code
in the class "org.eclipse.swt.widgets.Control" exits from the
line marked below, whereas when it does show up correctly it continues
on in the method:

public void setVisible (boolean visible)
{
        checkWidget
();
        if
(drawCount != 0) {
         
      if (((state & HIDDEN) == 0) == visible)
return;
        }
else {
         
      int bits = OS.GetWindowLong (handle, OS.GWL_STYLE);
       
        if (((bits & OS.WS_VISIBLE)
!= 0) == visible) return;   <<<======== exit from this line
when not working
        }
        if
(visible) {
         
      sendEvent (SWT.Show);
         
      if (isDisposed ()) return;
        }
        ...
}


I'm not familiar with that block on
code.  What does it mean?  Any ideas on why it would "fail"
from there?

Again any advice is appreciated.

Has anyone seen this kind of problem?  I have my own wizard and wizard
pages extending from a WTP wizard framework.  From the debugger I
can see that the pages are returned correctly from wizard's getNextPage()
and "createControl()" were called before the page is set visible.
 The page title and description are all shown correctly.  But
none of the controls on the page are shown. 

Any advice is appreciated.
