ediff frame appear in another page of Fvwm. How to debug/fix?

[Oleksandr Gavenko]

M-x ediff RET RET create ediff frame. It shown at right upper corner.

But recently it shown in another page of Fvwm, so I don't see main Emacs frame.

I try set:

(defun my-ediff-control-frame-position
(ctl-buffer ctl-frame-width ctl-frame-height)
(list '(name . "TEST Ediff") '(top . -10) '(left . -30)))

- now it appear on another page but lower right corner.

I try disable my Fvwm hack:

DestroyFunc MyFuncFocusWindow
AddToFunc MyFuncFocusWindow
+ I FlipFocus
+ I WarpToWindow 50 50
DestroyModuleConfig FvwmEvent-NewWindow
*FvwmEvent-NewWindow: Cmd
*FvwmEvent-NewWindow: Delay 1
*FvwmEvent-NewWindow: StartDelay 10
*FvwmEvent-NewWindow: add_window MyFuncFocusWindow

AddToFunc StartFunction I Module FvwmEvent
AddToFunc StartFunction I FvwmEvent FvwmEvent-NewWindow

and now ediff work good.

This Fvwm code emulate Windows focus behavior that I like.

Any suggestion to fix issue?

Are you talking about the ediff control window? Personally, I prefer it to be in the same frame as the buffers being compared: (setq ediff-window-setup-function 'ediff-setup-windows-plain).

But even when I use emacs -q and run ediff, the control frame never goes off the page, so it must be related to your Fvwm config. I doubt it has anything to do with changing focus; it's probably due to whatever placement styles you have enabled. Here is the part of my Fvwm config which is probably relevant:

,----
| Style * SnapAttraction 10 All Screen
|
| Style * ResizeOpaque
|
| Style * UsePPosition
|
| Style * MinOverlapPlacement
|
| # start on screen with pointer
| Style * StartsOnScreen c
|
| # do not jump to a desk that a window suddenly pops up on
| Style * SkipMapping
`----
,----
| # widows are focused by clicking on them
| # the focusing click is passed to the window
| # clicking in the window does not raise, but clicking on the decorations does
| Style * ClickToFocus, FPClickDecorToFocus
| Style * !FPClickRaisesFocused, !FPClickRaisesUnfocused, \
| FPClickDecorRaisesFocused, FPClickDecorRaisesUnfocused
|
| # programs can focus themselves
| Style * FPFocusByProgram
|
| # new windows/transients grab the focus when created
| # closing a window/transient releases focus to the previously focused window
| Style * FPGrabFocus, FPGrabFocusTransient, FPReleaseFocus, FPReleaseFocusTransient
`----

I don't have any emacs-specific fvwm styles. You should probably ask the Fvwm list.

I satisfied by ediff-setup-windows-plain!

I perform search in 'info emacs' and don't found this function...

I receive evidence as always fill that reading info page is start point, you
always need to read Emacs .el sources...

Next night I back to your config, have go to sleep now. Next issues I address
to fvwn user list.

Thanks for support!
