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

256 when it is created. In this case, you

|
|
257 need to call `make-frame-visible' to make
|
|
|
258 the frame appear.

259 popup If non-nil, it should be a frame, and this
|
|
|
260 frame will be created as a "popup" frame
|
|
|
261 whose parent is the given frame. This
|
|
|
262 will make the window manager treat the
|
|
|
263 frame as a dialog box, which may entail
|
|
|
264 doing different things (e.g. not asking
|
|
|
265 for positioning, and not iconifying
|
|
|
266 separate from its parent).
|
|
|
267 top Y position (in pixels) of the upper-left
|
|
|
268 outermost corner of the frame (i.e. the
|
|
|
269 upper-left of the window-manager
|
|
|
270 decorations).

271 left X position (in pixels) of the upper-left
|
|
|
272 outermost corner of the frame (i.e. the
|
|
|
273 upper-left of the window-manager
