383 These override what is specified in `default-frame-plist', but are

387 instead of through the frame-properties mechanism.

389 Here is a list of recognized frame properties, other than those

393 initially-unmapped If non-nil, the frame will not be visible

|
394 when it is created. In this case, you
|
|
|
395 need to call `make-frame-visible' to make
|
|
|
396 the frame appear.
|
|
|
397 popup If non-nil, it should be a frame, and this
|
|
|
398 frame will be created as a "popup" frame
|
|
|
399 whose parent is the given frame. This
|
|
|
400 will make the window manager treat the
|
|
|
401 frame as a dialog box, which may entail
|
|
|
402 doing different things (e.g. not asking
|
|
|
403 for positioning, and not iconifying
|
|
|
404 separate from its parent).
|
|
|
405 top Y position (in pixels) of the upper-left
|
|
|
406 outermost corner of the frame (i.e. the
|
|
|
407 upper-left of the window-manager
|
|
|
408 decorations).
|
|
|
409 left X position (in pixels) of the upper-left
|
|
|
410 outermost corner of the frame (i.e. the
|
|
|
411 upper-left of the window-manager
|
|
|
412 decorations).
|
|
|
413
|
|
|
414 See also `default-frame-plist', which specifies properties which apply
|
|
|
415 to all frames, not just mswindows frames.
