2850 instead of through the frame-properties mechanism.
|

2851
|
|
|
2852 Here is a list of recognized frame properties, other than those
|
|
|
2853 documented in `set-frame-properties' (they can be queried and
|
|
|
2854 set at any time, except as otherwise noted):
|
|
|
2855
|
|
|
2856 window-id The X window ID corresponding to the
|
|
|
2857 frame. May be set only at startup, and
|
|
|
2858 only if external widget support was
|
|
|
2859 compiled in; doing so causes the frame
|
|
|
2860 to be created as an "external widget"
|
|
|
2861 in another program that uses an existing
|
|
|
2862 window in the program rather than creating
|
|
|
2863 a new one.
|
|
|
2864 initially-unmapped If non-nil, the frame will not be visible
|
|
|
2865 when it is created. In this case, you
|
|
|
2866 need to call `make-frame-visible' to make
|
|
|
2867 the frame appear.
|
|
|
2868 popup If non-nil, it should be a frame, and this
|
|
|
2869 frame will be created as a "popup" frame
|
|
|
2870 whose parent is the given frame. This
|
|
|
2871 will make the window manager treat the
|
|
|
2872 frame as a dialog box, which may entail
|
|
|
2873 doing different things (e.g. not asking
|
|
|
2874 for positioning, and not iconifying
|
|
|
2875 separate from its parent).
|
|
|
2876 inter-line-space Not currently implemented.
|
|
|
2877 toolbar-shadow-thickness Thickness of toolbar shadows.
|
|
|
2878 background-toolbar-color Color of toolbar background.
|
|
|
2879 bottom-toolbar-shadow-color Color of bottom shadows on toolbars.
|
|
|
2880 (*Not* specific to the bottom-toolbar.)
|
|
|
2881 top-toolbar-shadow-color Color of top shadows on toolbars.
|
|
|
2882 (*Not* specific to the top-toolbar.)
|
|
|
2883 internal-border-width Width of internal border around text area.
|
|
|
2884 border-width Width of external border around text area.
|
|
|
2885 top Y position (in pixels) of the upper-left
|
|
|
2886 outermost corner of the frame (i.e. the
|
|
|
2887 upper-left of the window-manager
|
|
|
2888 decorations).
|
|
|
2889 left X position (in pixels) of the upper-left
|
|
|
2890 outermost corner of the frame (i.e. the
|
|
|
2891 upper-left of the window-manager
|
|
|
2892 decorations).
|
|
|
2893 border-color Color of external border around text area.
|
|
|
2894 cursor-color Color of text cursor.
|
|
|
2895
|
|

2897 to all frames, not just X frames.
