476726 - deCOMtaminate WidgetToScreen and ScreenToWidget

Status: RESOLVED FIXED

(Core :: Widget, defect)

Description

[Jeremy Lea]

Attachment: v1.0

This is a small patch to fix replace WidgetToScreen and ScreenToWidget with WidgetToScreenOffset, which just returns an nsIntPoint.  Passes tests on Linux and Windows, and seems OK on Mac, although the ObjectiveC code could do with a special look.  OS/2 and Qt changes as a courtesy - totally untested.  Should have no performance downside.

I noticed there is a larger bug for nsIWidget.h, which I've added as a blocker.  I'm not sure if anyone is working on that, but i thought I would file a separate bug for this.

v1.0

+    NS_IMETHOD_(nsIntPoint) WidgetToScreenOffset() = 0;

I would just make this
  virtual nsIntPoint WidgetToScreenOffset() = 0;

+    aRect.MoveTo(WidgetToScreenOffset());
+    aRect.SizeTo(mBounds.Size());

  aRect = nsRect(WidgetToScreenOffset(), mBounds.Size());
(two occurrences)

Why does it always seem someone bitrots my patches just when I'm done testing them... ;-)

Revised patch, with fixes for build failures.  Changes are minor and obvious, so no re-review.

2 probably missed comments:
{
/view/src/nsView.cpp
    * line 407 -- // to compute their true screen position. This could mean that WidgetToScreen

/widget/src/gtk2/nsWindow.cpp
    * line 3201 -- // in scroll_event_cb(), so use ScreenToWidget to translate the screen root coordinates into
}

Also, what about Beos and Photon ports: need to file follow-up bugs !?

This patch broke building on Qt. I filed bug 480689 for the breakage.
