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

263 when it is created. In this case, you

264 need to call `make-frame-visible' to make
|
|

265 the frame appear.

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

275 outermost corner of the frame (i.e. the

|
276 upper-left of the window-manager
|
|
|
277 decorations).

278 left X position (in pixels) of the upper-left
|
|
|
279 outermost corner of the frame (i.e. the

|
280 upper-left of the window-manager
