1422 be confusing because the text area (the EmacsFrame widget inferior of

1423 the shell) is also called that. So we just set the WM_CLASS property.

2255 Here is a list of recognized frame properties, other than those

2256 documented in `set-frame-properties' (they can be queried and

2257 set at any time, except as otherwise noted):
|
|
|
2258
|
|
|
2259 window-id The X window ID corresponding to the
|
|
|
2260 frame. May be set only at startup, and
|
|
|
2261 only if external widget support was
|
|
|
2262 compiled in; doing so causes the frame
|
|
|
2263 to be created as an \"external widget\"
|
|
|
2264 in another program that uses an existing
|
|
|
2265 window in the program rather than creating
|
|
|
2266 a new one.
|
|
|
2267 initially-unmapped If non-nil, the frame will not be visible
|
|
|
2268 when it is created. In this case, you
|
|
|
2269 need to call `make-frame-visible' to make
|
|
|
2270 the frame appear.
|
|
|
2271 popup If non-nil, it should be a frame, and this
|
|
|
2272 frame will be created as a \"popup\" frame
|
|
|
2273 whose parent is the given frame. This
|
|
|
2274 will make the window manager treat the
|
|
|
2275 frame as a dialog box, which may entail
|
|
|
2276 doing different things (e.g. not asking
|
|
|
2277 for positioning, and not iconifying
|
|
|
2278 separate from its parent).
|
|
|
2279 inter-line-space Not currently implemented.
|
|
|
2280 toolbar-shadow-thickness Thickness of toolbar shadows.
|
|
|
2281 background-toolbar-color Color of toolbar background.
|
|
|
2282 bottom-toolbar-shadow-color Color of bottom shadows on toolbars.
|
|
|
2283 (*Not* specific to the bottom-toolbar.)
|
|
|
2284 top-toolbar-shadow-color Color of top shadows on toolbars.
|
|
|
2285 (*Not* specifier to the top-toolbar.)
|
|
|
2286 internal-border-width Width of internal border around text area.
|
|
|
2287 border-width Width of external border around text area.
|
|
|
2288 top Y position (in pixels) of the upper-left
|
|
|
2289 outermost corner of the frame (i.e. the
|
|
|
2290 upper-left of the window-manager
|
|
|
2291 decorations).

2292 left X position (in pixels) of the upper-left
