2812

2813 Here is a list of recognized frame properties, other than those

2814 documented in `set-frame-properties' (they can be queried and

2815 set at any time, except as otherwise noted):
|
|

2816
|
|
|
2817 window-id The X window ID corresponding to the
|
|
|
2818 frame. May be set only at startup, and
|
|
|
2819 only if external widget support was
|
|
|
2820 compiled in; doing so causes the frame
|
|
185
|
2821 to be created as an "external widget"
|
|
0
|
2822 in another program that uses an existing
|
|
|
2823 window in the program rather than creating
|
|
|
2824 a new one.
|
|
|
2825 initially-unmapped If non-nil, the frame will not be visible
|
|
|
2826 when it is created. In this case, you
|
|
|
2827 need to call `make-frame-visible' to make
|
|
|
2828 the frame appear.
|
|
|
2829 popup If non-nil, it should be a frame, and this
|
|
185
|
2830 frame will be created as a "popup" frame
|
|
0
|
2831 whose parent is the given frame. This
|
|
|
2832 will make the window manager treat the
|
|
|
2833 frame as a dialog box, which may entail
|
|
|
2834 doing different things (e.g. not asking
|
|
|
2835 for positioning, and not iconifying
|
|
|
2836 separate from its parent).
|
|
|
2837 inter-line-space Not currently implemented.

2838 toolbar-shadow-thickness Thickness of toolbar shadows.

2839 background-toolbar-color Color of toolbar background.

2841 (*Not* specific to the bottom-toolbar.)

2844 internal-border-width Width of internal border around text area.
