I'm really getting tired of this problem, and for a while it was
fixed, but seems to have broken again recently.
I have a document based Cocoa application that holds a WebView. The
position and size of the window, initially, is a fixed size. This
works fine -- the application starts, opens a window, loads a URL, etc.
However, when another window is opened, in response to a javaScript
"window.open" call, this is the behaviour:
1) The new window opens on the screen, in the full size
2) The window is moved and resized to the correct dimensions
3) The WebView updates
This looks terrible, because there's a very evident "flashing" that
happens.
If I step into the code with the debugger, there is nothing on screen
until I make this call:
[myFrame loadRequest:[NSURLRequest requestWithURL:fileURL]];
Immediately after that line, when I switch to the paused application,
I see a full size empty window on the screen. The resize and
reposition happens in system code, not accessible. When I had this
problem in the past, it didn't appear on this call, so this seems to
be something new with 10.5.x
What I want to happen is pretty simple:
1) At an early point in the load process, I want to put in something
that says "Never, under any circumstances, show this window until I
specifically call makeKeyAndOrderFront or do something else manually
to show the window"
2) After the WebView has loaded, then, and only then, do I want the
window to appear.
Note that this has nothing to do with the "Visible at Launch" flag in
IB.
Ideas or suggestions greatly appreciated!
